The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish jet fighter {{Battle-rating}}. It was introduced in [[Update 1.97 "Viking Fury"]].
+
The '''{{Specs|name}}''' is a rank {{Specs|rank}} British medium tank {{Battle-rating}}. It was introduced in [[Update 1.71 "New E.R.A."]].
  
The {{PAGENAME}} is the first Swedish jet capable of Mach 2. The jet is highly agile and is the first plane in War Thunder capable of performing the famous "Cobra manoeuvre".
+
The Chieftain Mk 10 is the first vehicle available in the British main research tree with APFSDS available for research, significantly improving the vehicle's gun performance once unlocked.

=== Survivability and armour ===
<!-- ''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.'' -->
+
<!-- ''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.'' -->
 +
The Chieftain Mk.10 sports identical hull armour to the earlier variants, however the turret is augmented with Stillbrew composite armour, providing near-complete frontal protection when in hull-down positioning, with the exceptions of the small area around the gun breech and a small section of visible turret ring. The Chieftain's Stillbrew package offers extremely effective protection against most kinetic rounds, with only rounds available on vehicles such as the T-80B and Type 90 able to penetrate it.
  
The Saab {{PAGENAME}} Draken is a highly agile interceptor of the Swedish aviation family. This interceptor uses a double delta wing-configuration and a powerful Avon engine to achieve both excellent high and low-speed performance at various altitudes. This aircraft is outfitted with two wing-mounted Akan m/55 auto-cannons and up to four [[Rb24|RB24]]/[[RB24J]] missiles. Along with options for both anti-air and anti-ground rockets, the {{PAGENAME}} becomes a versatile platform with a high potential thanks to unmatched maneuverability. Having almost twice the wing surface of a [[MiG-21MF (Germany)|MiG-21MF]], the {{PAGENAME}} comfortably dogfights any opponent who dares to challenge it.
+
The vehicle's hull armour should be considered essentially non-existent relative to the weaponry it faces; in most cases a hull shot will result in penetration.
  
The cost of this maneuverability is the large reduction in speed when turning. The {{PAGENAME}} usually drops below 500 km/h airspeed when performing aggressive maneuvers. This lack of speed usually leaves the {{PAGENAME}} vulnerable to enemy attacks, since avoiding missiles or gunfire becomes a lot more difficult. This makes the {{PAGENAME}} a unique flying experience where the player needs to be constantly aware of the current airspeed, while still avoiding dumping all speed at once. In order to maximize the stored speed, the {{PAGENAME}} should be flown carefully. Aerial maneuvers should be avoided and turning has to be done slowly. The efficiency of the {{PAGENAME}} significantly increases when played with higher speeds. Although the plane becomes more sluggish at speeds close to 1,100 km/h, the {{PAGENAME}} still manages to outmaneuver incoming missiles. Avoiding incoming homing devices usually leads to deceleration, but with careful planning, this speed can always be regained thanks to the strong acceleration the engine provides.

=== Mobility ===
 +
<!-- ''Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forwards and backwards.'' -->
 +
 
 +
{{tankMobility|abMinHp= 1178|rbMinHp= 672}}
 +
 
 +
The {{PAGENAME}}'s mobility is extremely sub-par, particularly when considering the vehicles it will face regularly - such as the [[Leopard A1A1]] or the [[AMX-30 Super]]. While the vehicle is ''technically'' capable of a maximum of 48 km/h in RB/SB, the lacklustre power and the {{PAGENAME}}'s significant weight result in this speed being essentially unattainable except in on-road downhills.
 +
 
 +
As such, {{PAGENAME}} players should not rely on their mobility for anything; rather they should make their way to positions with good visibility and attempt to maintain ranged engagements only, relying on their turret armour.

 +
{{main|Ordnance BL Tk. L11 (120 mm)}}
 +
 
 +
The L11 120mm Rifled Cannon is reasonably competitive at the Chieftain's rank, although it does suffer from a somewhat mediocre reload time. The weapon is extremely accurate, particularly once utilising the L23 APFSDS round, and performs admirably in ranged engagements. The weapon's default APDS and HESH rounds can be used to good effect against most targets, given careful aim and target selection.

=== Survivability and armour ===
 
<!-- ''Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.'' -->
 
[[File:J35D protection.jpg|thumb|400px|right|The '''{{PAGENAME}}''' forgoes armour for additional speed and manoeuvrability.]]
 
 
The {{PAGENAME}} is one of the many high-rank planes entirely without protection, much like the [[F-4 Phantom II (Family)|F-4 Phantom]] series of fighters. Although the later variants of the Draken featured bird strike-proof cockpits, no Draken variant was fitted with armour plating or bulletproof glass. In-game, this downside can be quite hard to notice since higher rank vehicles tend to boast incredible amounts of firepower, making every hit incredibly devastating. A {{PAGENAME}} pilot should, like every other pilot, avoid damages at all costs as any damage deteriorates the aircraft's performance and ability to stay in the fight.
 
 
== Armaments ==
 
=== Offensive armament ===
 
<!-- ''Describe the offensive armament of the aircraft, if any. Describe how effective the cannons and machine guns are in a battle, and also what belts or drums are better to use. If there is no offensive weaponry, delete this subsection.'' -->
 
{{main|Akan m/55 (30 mm)}}
 
 
The '''''{{PAGENAME}}''''' is armed with:
 
 
* 2 x 30 mm Akan m/55 cannons, wing-mounted (90 rpg = 180 total)
 
 
The {{PAGENAME}} is outfitted with two 30 mm Akan m/55 cannons, which are Swedish manufactured variants of the British [[ADEN (30 mm)|ADEN]] cannons. These two cannons offer a high burst mass and velocity at medium ranges. Although these guns are dangerous, they are quite limited by their ammunition count. Just like the J32B, these cannons have 90 rounds each, giving the player a total of 180 shells. The cannons should be fired with caution in order to maximize the amount of damage they provide. Since the missiles are outdated RB24 missiles, a {{PAGENAME}} pilot needs to be prepared to engage most enemies with these cannons rather than suspended armaments.
 
 
Another issue with the {{PAGENAME}} is the cannon placement. The two Akans are wing-mounted rather than center-mounted. This is a downgrade compared to the gun placement found on the earlier J32B since set convergence now plays a role. This makes the {{PAGENAME}} lose effectiveness at certain ranges since the target has the chance to fly between the shells, and when hitting a target, the shells are unlikely to concentrate to a singular point, lowering the amount of damage created. This placement creates difficulty in complex maneuvers, since putting the plane sideways creates a vertical spread. A wise {{PAGENAME}} pilot will commence target practice with the guns prior to battle as they are important for the plane's overall survivability and combat effectiveness.
 
 
=== Suspended armament ===
 
<!-- ''Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.'' -->
 
The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:
 
 
* Without load
 
* 12 x m/56D rockets
 
* 38 x srak m/57B rockets
 
* 4 x RB24 missiles
 
* 2 x RB24 missiles + 12 x m/56D rockets
 
* 2 x RB24 missiles + 38 x srak m/57B rockets
 
 
 
{{main|m/56D}}
 
 
The {{PAGENAME}} is able to carry 12 suspended m/56D unguided rockets for ground-strike purposes. These rockets have a TNT filler with the same penetration as the earlier [[m/49A]] found on the earlier ground-strike planes. The rockets fire individually starting from the left, and are placed in a vertical angle, These rockets are devastating against lighter vehicles at high tiers. Thanks to a single-fire system and good velocity, the effectiveness can be quite high if practiced. But due to the {{PAGENAME}} being only available for use at top-tier, these rockets have a very low chance of reliably working, since the targets are usually heavily armoured. The {{PAGENAME}} lacks a ballistic missile computer and is easily countered by missile SPAA, making the {{PAGENAME}} a bad pick for close air support in general. If the player feels the need for a challenge, the {{PAGENAME}} is at the very least highly maneuverable, giving players the option to do several dangerous passes in a short period of time.
 
 
{{main|srak m/57B}}
 
 
The {{PAGENAME}} offers a pair of unguided m/57B rocket pods. These rockets are designed for bomber interception, and are very devastating against aerial targets. These rockets fire in pairs, in contrast to the single-fire m/56D rockets for ground-attack purposes. Being placed parallel with the plane, these rockets are comfortable to aim due to the traditional angle, as well as the center fuselage mounting they offer. These pods weigh less than the full RB24 loadout, but still require a {{PAGENAME}} pilot to engage targets the same way as with the internal Akan m/55 cannons, making them quite redundant. These pods are for pilots looking for a challenge, while still staying effective in aerial combat.
 
 
{{main|Rb24}}
 
 
A later modification found on the {{PAGENAME}} is the option to carry four RB24 missiles, the same being found on the previous J32B Lansen. These missiles are mounted separately from each other, with two under the center fuselage, and two under the outer delta. Having four of these missiles significantly lowers the performance of the {{PAGENAME}}, meaning that more aggressive players should consider if they will find a practical use for this suspended armament. Defensive and more cautious players will, however, enjoy these missiles since they offer a more distanced approach to engaging targets. A pilot should still be aware that these missiles tend to miss most opponents at high-tier due to missile countermeasures, as well as higher speeds and maneuverability found at these tiers.
 
 
''Main article: [[RB24J]]''
 
 
The crown jewel of the {{PAGENAME}}'s modifications are the four RB24J air-to-air missiles carried under the same pylons as before. These missiles have twice the G-load and a wider seeker, giving it a lot more flexibility than its older counterpart. Thanks to their supreme mobility, they can easily engage and destroy close opponents with minimal effort. This feature is incredibly helpful for the {{PAGENAME}}, since most engagements forces the plane to slow down. The RB24J air-to-air missiles allows the {{PAGENAME}} to close the gap between the enemy and itself, no matter the difference in speed, making it one of the most important tools in the {{PAGENAME}}'s arsenal. This missile is heavily recommended for any pilot that wants to make the most out of their own Draken.

The {{PAGENAME}} can be a bit "over the top" when it comes to in-game performance. The {{PAGENAME}} doesn't underperform in any area, even when stock. Yet the {{PAGENAME}} quickly suffers when facing several opponents at once. This is due to the incredible maneuverability the {{PAGENAME}} possesses, which becomes its worst enemy in battles. The {{PAGENAME}} comfortably dodges incoming enemies when at higher speeds, but quickly loses this advantage after the first few passes due to the reduction of speed. Avoiding can still be done easily, but high-load missiles require a speed above 800 km/h to be reliably dodged. To avoid the likelihood of a low-speed experience, the {{PAGENAME}} should maneuver with caution, with the same style as a pilot preventing wings from ripping. The recommended way to use this trick is to control the elevators with the use of the "pitch axis" button. By tapping this button rapidly, a {{PAGENAME}} pilot can prevent high-G maneuvers while still keeping their backs cleared by looking behind them in a defensive-like approach. The amount of pulling can be varied depending on what is approaching the Draken. It's important to remember that aileron rolling can still be done without much consequence, and will come in handy when avoiding enemies in a defensive situation.
+
The Chieftain Mk 10 plays similarly to the Mk 3/Mk 5 - ideally taking long-ranged engagements from hull-down positions, or when forced into shorter-ranged engagements avoiding exposing the vehicle as much as possible. Fortunately, the Stillbrew addition on the Mk.10 significantly reduces the risks of exposing the turret, with the composite capable of deflecting most kinetic rounds it will face - although the armour package is not invulnerable to chemical rounds; some powerful HEAT rounds and most late ATGMs will easily punch through it. Augmenting the vehicle's ability further is the (researchable) access to L23 APFSDS, which significantly improves the L11's long range efficacy. Despite these improvements, the Chieftain still suffers from mediocre mobility and care must be taken to ensure one does not get engaged while the vehicle is moving, as the ability to quickly move into cover is often not an option.
 
 
'''Attacking while using the Akan m/55'''
 
 
 
When the {{PAGENAME}} isn't on the receiving end of an attack, the dominating maneuverability and acceleration start to show. The Draken has the ability to stick with almost any enemy. A rude, but effective approach is to engage already slow enemies since the Draken will never overshoot a target. This should also be done with caution since this is still a sacrifice of valuable energy required to avoid incoming attacks. Learning when to strike is key for the {{PAGENAME}}, since staying alive is always a number one priority.
 
 
 
When it comes to firing on a target, the {{PAGENAME}} immediately shows it's unorthodox gun placement. Shooting opponents running away, or firing on bypassing enemies might often result in the {{PAGENAME}} missing the target entirely. To avoid this, a pilot can both train their aim and learn useful aerial maneuvers to increase the likelihood of hitting opponents. A general tip when firing upon passing opponents is to make the enemy pass the {{PAGENAME}} along its horizontal axis. This ensures that the target passes through both guns, and the time on target automatically increases. Although this tactic won't focus as much lead on a singular point as a regular approach, it will still assure some shells connect with the target, which is usually enough to finish off any opponent.
 
  
'''Attacking while using the RB24 and RB24J'''
+
'''Specific Adversaries'''
  
The missile gameplay favors altitude and separation over head-on engagements and dogfights. Thanks to the {{PAGENAME}}'s performance, the plane can easily flank to the side or reach incredible altitudes while keeping a safe speed. Catching enemies off-guard can be quite difficult, but trying to stay off the radar lock function (keeps you hidden from RWR), is a good start. The early RB24 missiles have no real use of Radar locking, while the RB24J's improve significantly from this function. Avoid locking them until you're in a close proximity to the target. The more speed you have compared to the target also affects the result. A slower opponent has less time to react, while a faster one has extra time and usually agility to avoid incoming homing devices. It's important to know which planes you're attacking and when they're vulnerable to incoming attacks. Even if the missile doesn't hit, the {{PAGENAME}} can easily catch up with the enemy due to their slower speed afterwards. It's important to still make good use of the Akan m/55 while playing with suspended armament. These missiles can effectively help close the distance between the {{PAGENAME}} and its target, where gunfire is ideal. This also spreads out the missiles between opponents, letting the {{PAGENAME}} rank up more kills when played strategically.
+
'''[[T-64B]]/[[T-80B]]:''' The Chieftain is susceptible to the T-64B and T-80B at close to medium ranges, where their highest-performance APFSDS rounds or their ATGMs are capable of punching through the Stillbrew armour. As such, when forced to engage either of these vehicles try to force mistakes by staying in cover, encouraging them to move within your firing line rather than attempting to brute-force your way through them.
  
'''Superstalling'''
+
'''[[Leopard 2K]]:''' The Leopard 2K is a dangerous adversary due to its speed and ability to move quickly and potentially flank the Chieftain Mk.10, as well as its 650mm HEAT round which the Stillbrew will not reliably protect against. The Leopard ''is'' however fairly easy to destroy due to its essentially non-existent armour - although don't underestimate the ability for the sharp angles to bounce rounds.
  
The {{PAGENAME}} features one of the largest wing-areas of any fighter. Although this gives the {{PAGENAME}} a high advantage in terms of manoeuvrability and speed, the plane suffers from a unique, but dangerous downside. This downside becomes apparent when damaged, stalling, or deploying negative elevator for a extended period of time. This feature is known as a "superstall", and can result in complete destruction of the aircraft. A superstall can be noticed by the parachute-like falling the plane experiences. The plane spins, and can't exit the manoeuvre for a extended period of time. In order to exit a superstall, the {{PAGENAME}} is outfitted with four tiny air-brakes positioned at the rear of the aircraft. Deploying these air-brakes will pull the tail-section upwards, allowing a {{PAGENAME}} pilot to regain airflow under their wings. It's important to avoid superstalling since the {{PAGENAME}} stays incredible vulnerable during this period.
+
'''[[AMX-40]]:''' The AMX-40 is a threat to the Chieftain Mk.10 for similar reasons to the Leopard 2K; as with the Leopard, be wary of flanks and the power of the AMX-40's APFSDS.

'''Pros:'''
 
'''Pros:'''
  
* Superior manoeuvrability - able to out-turn anything it wishes
+
* Stillbrew composite armour makes a hull-down Chieftain essentially impervious to all but the best kinetic rounds. It is also resistant to most rank VI chemical rounds and early generation ATGMs. Due to this, the tank is a nightmare to fight with outdated tanks for many nations, as not many tanks can even scratch its turret directly to begin with
* High top speed - can catch most top tier aircraft at low altitudes
+
* The L23 APFSDS round is very powerful and will have little trouble penetrating most vehicles at the Chieftain's rank
* Strong acceleration
+
* 10° of gun depression
* Easy and short takeoff/landing
+
* Reasonably fast reload time for a 120mm with a base time of 9.5s and a best time of 7.5s
* Slow stall speed - air-brakes prevent "superstalling"
+
* Reasonable reverse speed
 +
* Receives a Laser Rangefinder as a Tier 4 modification, the first British vehicle this is available on
  
 
'''Cons:'''
 
'''Cons:'''
  
* Poor sustained turning - sustained speed degenerates quickly when manoeuvring at speeds below 1,000 km/h
+
* Stillbrew composite armour does not provide particularly good chemical protection against upgraded rank VI ATGM, which means, that while it can often allow Chieftain Mk 10 to ignore ATGM attacks from tanks like [[Begleitpanzer 57]], [[KPz-70]] or [[M551]] and maybe even some attacks from unskilled [[IT-1]] operator, in up-tier or against specialized rank VI ATGM tanks and tanks, which can carry advanced ATGM ( like [[BMP-1]], [[BMP-1 (DDR)]], [[BMP-2]], [[Type 89]], [[Warrior]], Etc.), the tank commander must be much more cautious
* Unorthodox gun placement - less accurate and more tricky to get used to
+
* While turret is near invulnerable to shells with poor flight characteristics, it still retains a glaring weakspot in form of cupola, which can be penetrated and obliterated by almost any APHE, sometimes even from light tanks such as [[Begleitpanzer 57]], resulting in full crew knockout. Because of this, Chieftain Mk 10 is usually forced to keep their enemies away, even when going to the frontline
* Lack of countermeasures - no flares or RWR
+
* Very poor mobility characteristics, much slower than most medium tanks it have to face
* Sluggish performance when paired with suspended armaments
+
* Hull armour is negligible, comprised only of Cast Homogenous armour, which means that it is even weaker, than what it looks like
* Low amount of fuel, make it vulnerable in case of prolonged engagement
+
* Hull penetration will often result in ammunition detonation as ammo is strewn throughout it

===Concept===
 +
The idea of a "universal tank" began in Britain in 1944 when Montgomery and other influential people began advocating for a more standardized tank to replace the cruiser and infantry tank classes used on the field. Efforts did not start until after World War II under the General Staff designation A45, with development starting just as the new cruiser tank [[Centurion Mk 3|Centurion]] started to enter military service. The A45 was cancelled in 1948 after development troubles and its inability to be used as a "universal" platform. Ironically, the Centurion proved to be a better "universal tank" platform than the A45.<ref name="DunstanChieftain">Dunstan Simon. ''Chieftain Main Battle Tank 1965-2003'' Great Britain: Osprey Publishing Ltd., 2003</ref>
  
;Background
+
===Development===
 +
The [[Centurion Mk 10|Centurion]] tank series was very successful in British and its allies' service, but the development of new Soviet armour such as the [[IS-3]] and [[T-54 (1951)|T-54/55]] caused the British tank arms race to take another leap forward. Development on the Centurion's successor began in 1951 under the name ''Medium Gun Tank No. 2''. The project's priority was gun and armour, but with mobility to be equal to the Centurion's and weight of fewer than 45 tons. The weight limit caused a program known as the Concept Study Programme to commence in order to find ways to keep the tank under that weight limit yet meet all the armour and firepower specifications. One of the concepts that came out was the usage of bagged charges, which was already in use on naval ships but was a new concept for tank ammunition. Thus, a gun using the bagged charge propellant system began development in 1954, along with a new specification by General Staff that the Medium Gun Tank No.2, now known as ''FV4201'', uses a conventional four crew tank with a turret and a better gun and armour than the Centurion. Though the [[Conqueror]] heavy tank was one such response to the firepower requirement, limited production cut that to only 200 units built.<ref name="DunstanChieftain">Dunstan Simon. ''Chieftain Main Battle Tank 1965-2003'' Great Britain: Osprey Publishing Ltd., 2003</ref>
  
The discussion about a new fighter project, capable of intercepting small groups of bombers at an altitude of 10 kilometres, was brought up in the autumn of 1949, just a few months from the introduction of the [[J29A|J29 Tunnan]]. The threat was deemed to be transonic bombers, which needed to be intercepted before reaching Swedish airspace. This meant the next big project, Saab would focus on a high-speed interceptor capable of exceeding the Mach number, while still being able to function as an all-weather, daytime fighter.
+
The biggest bump to the firepower of the FV4201 was the recommendation of a 120 mm calibre tank cannon. Though the Conqueror used a 120 mm, the new one would incorporate more innovative features such as the bagged charges. Other design features added was the usage of a Rolls-Royce V8 engine, an auxiliary engine, an automatic gearbox, and a reclining seat for the driver. The reclining seat was a very new feature in tank design as it reduced the vehicle's hull height and thus gave it a lower profile. Leyland Motors was assigned to be the main designer for the tank despite their commitment to the Centurion production lines. The manufacturing process of the tank was decided to be cast rather than welded. In 1957, several specifications added to the FV4201 impeded its attempt to fit in the specifications. A bigger turret was designed and it mounted IR equipment for night fighting. Troops requested more frontal and turret side armour, which along with the turret change caused an increase in the tank's overall weight. A controversial decision was also made in 1957 by NATO that tanks should have multi-fuel engines. The FV4201 installed a new engine conforming to these standards in 1958, a German engine derived from a Junkers Jumo aviation engine. This extended development time since the engine compartment had to be redesigned to fit the engine, raising the total tank weight to 50 tons. The engine, designated the L60, was received with a mixed reception by the Royal Armoured Corps (RAC) and other users due to its novel features. Britain stayed as the only user of a multi-fuel engine in the Cold War as many other nations found the concept impractical and abandoned it.<ref name="DunstanChieftain">Dunstan Simon. ''Chieftain Main Battle Tank 1965-2003'' Great Britain: Osprey Publishing Ltd., 2003</ref>
  
;Saab 210 Lilldraken
+
As the FV4201 finalized its prototype stages, General Staff sent a revised specification for it. The tank was to have the firepower of the Conqueror with the mobility of the Centurion, an armour that maximizes the protection-weight ratio, a weight limit at 45 ton with a top speed of 26 mph and an operating range of 300 miles. The first wooden prototype was made in March 1959, with full prototypes ordered in June 1959 for troop trials. Vickers-Armstrong and Royal Ordnance Factory shared the manufacturing process and the first prototypes were built in January 1960. The first two prototype FV4201 was trialled in Germany alongside their new [[Leopard I|Leopard 1]]. The greatest issue with the FV4201 was the engine, which caused many failures due to vibration, a result of the flawed multi-fuel concept. Trials were delayed due to lack of parts to fix broken pieces and redesigns were requested to fix problems. After a lengthy trial period in 1962, the FV4201, now named the '''Chieftain''', was sent to the operational unit in Germany for service and combat trials. The Chieftain was finally accepted for service in 1st May 1963, despite the many faults in the design. The first deliveries of the improved and redesigned Chieftains began in mid-1965. These were the ''Chieftain Mk 1's'', which further revealed problems with the horsepower that the ''Mk 2'' was designed and sent in April 1966. The ''[[Chieftain Mk 3]]'' rolled out of the production lines in September 1969, it now weighed 53 tons and the L60 engine was producing 650 hp, still underpowered for the weight. Engine failures were still frequent and left the Chieftain with a sour note until the [[Chieftain Mk 5|Mk 5]] variant fixed these pressing issues with a new engine and NBC protection. The Mk 5 would be the main variant of the Chieftain in British service. During its production life from 1965 to 1985, a total of 2,265 Chieftains would be built by Britain, with about 1,000 used by the British Army.<ref name="DunstanChieftain">Dunstan Simon. ''Chieftain Main Battle Tank 1965-2003'' Great Britain: Osprey Publishing Ltd., 2003</ref>
  
This new project for a supersonic fighter-interceptor was given the name "project 1200". This project would be lead by the Saab engineer Erik Bratt. His team tinkered with various ideas on how to create a supersonic fighter with low-speed handling, to ease landing on shorter runways. The team came up with a double delta design that made use of two wing angles, giving the plane less drag at higher speeds, while staying maneuverable at lower speeds. In order to test this design, the team constructed a miniature version of the new fighter, named Saab 210, which also received the nickname "Lilldraken" (translates to small kite). This plane was just 70% the size of the regular Draken and was used for extensive testing of handling as well as ergonomics of a double delta configuration. This prototype was first flown on January 21st, 1952.
+
===Service===
 +
The first British units to receive the Chieftains was the 1st and 5th Royal Tank Regiments back during the trials. The Chieftain, despite its initial engine flaws, proved to be combat-proof and could be upgraded to fit new requirements. Some of these upgrades were the addition of composite add-on armour to fight off new anti-tank technology such as the HEAT rounds. The Chieftain earned the title "most formidable tank in the world" during the 1960's Cold War period and also redefined the specifications of a "main battle tank". Its success is due to its novel main gun and heavily sloped armour, as well as satisfactory mobility and speeds able to compete with the Leopard 1. The Chieftain stayed in use by the British Army On the Rhine on the German border with the Warsaw Pact, which caused the Soviets to in turn station their best tanks such as their [[T-64A (1971)|T-64's]] against the Chieftains. The British retained the Chieftains all the way until 1997, when it was replaced by the Challenger II, initially being used in addition to Challenger I.
  
The Saab 210 would see many changes to its design in order to finalize the look of the upcoming J35 Draken. The nose was changed to better suit radar use, its air intakes moved back for a better view, and the tail reconstructed to fit a drag-chute. All of which would be found on the J35 Draken later on.
+
The Chieftain was also successful in the export market, primarily in the Middle East to the hands of Iran, Jordan, Kuwait, and Oman. Another user of the Chieftain was Israel, with Britain initially agreeing to help set up production for locally produced Chieftains. Two Chieftains were sent for trials among the Israeli Defense Force in 1967. After two years of trials and deliberation for the acquirement of the Chieftains, Britain ultimately refused to offer the Israelis the Chieftain for political reasons. The Israeli trials benefit Britain with data on desert combat with the Chieftain, however, and the refusal did jump start Israel's tank program that would become the ''Merkava''.
  
;Saab 35 Draken
+
Despite that, sales to the Middle East soared, with Iran being the major buyer of the Chieftains with at least 887 of mostly the MK3 and MK5 variants sent to them before their revolution in 1979. The Chieftain saw prolonged combat in the Middle East in the Iran-Iraq War, including Operation Nasr which was the largest tank vs. tank battle of the war where the Iranian Chieftains and [[M60A1 (AOS)|M60A1 Pattons]] fought against the Iraqi [[T-62]]s. After that war, the Chieftain in Kuwait then saw combat fighting the Iraqis during their invasion in 1990. Kuwait eventually replaced their Chieftains with the Yugoslavian M-84 tanks, which are a variant of the Soviet T-72s.
  
[[File:Saab 35 Draken prototypes.jpg|thumb|Two prototype Saab 35 Draken flying in formation.]]
+
The Chieftain is still in service Iran, Jordan, and Oman in varying numbers, about 100 in Iran, 350 in Jordan, and 27 in Oman. The Chieftains underwent local upgrades to keep them up to date against a modern threat, which resulted in the Iran ''Mobarez'' Chieftain upgrade.
With the tests finished, the Draken would finally see full-scale prototypes. The first prototype took to the skies in October 1955, and deliveries of the first variant, the J35A, would commence in 1959. By 1960 the first Drakens would officially be in service. These would be stationed at F13 Bråvalla and F16 Gotland. Later variants would be placed all over Sweden, with various purposes. Being used for bomber interception, reconnaissance and trainers, the Saab 35 Draken would see the longest service life of any fighter in the Swedish air force. The Draken would serve for almost 40 years, having 615 planes produced during its lifespan.

===Legacy===
 
+
The Chieftain helped revolutionize tank design with its innovative features. The most important was the reclining driver seat, which allowed the tank to have a lower profile as the driver was now that highest part of the hull in tank design. It also had the most powerful NATO tank armament in service until the advent of the German Rheinmetall 120 mm, which came about two decades later. Chieftain can be considered the definitive main battle tank of the 1960s and help transition the path between second-generation main battle tanks and the third.
The {{PAGENAME}} was the 4<sup>th</sup> Draken variant that was planned and built due to the new requirements the Swedish KFF (Kungliga FlygFörvaltningen or Royal air ministry) issued to Saab. The new requirements specified that the next fighter had to intercept high altitude bombers flying at Mach 1.5, while still carrying the same weaponry and ordinance the earlier J35B offered. This required Saab to upgrade the RM6B engine found on the J35B, which meant the design had to be slightly altered. The air intakes were elongated, and the fuselage got altered to support the use of drop-tanks in the center. The first {{PAGENAME}} took to the skies on the 28th of August 1962, but the first planes delivered would be without radar equipment. These would be known as the J35D1, of which 24 of which were made. The other planes got the name J35D2 and would later be known as the {{PAGENAME}} when the original D1s got their radar equipment installed. 
 
 
 
A total of 120 {{PAGENAME}} Drakens would be built between 1963-1964. Being outfitted with the Rm 6C (Avon 300-series), this version was the fastest Draken to take to the skies. This Draken would also be exported to the Austrian air-force. In order to export these planes to Austria, Saab ended up buying back 24 of the Swedish serving {{PAGENAME}}s and converting them to the Austrian requirements, which meant fitting the planes with the bird-proof cockpit from the J35F, as well as repainting them for Austrian service. These Austrian Drakens, designated J35Ö (sometimes designated J35OE), saw extensive use all the way towards the 21st century, being taken out of service in 2005.

In the late 1940s, the Swedish Ministry of Defence released a set of requirements for a new, cutting edge jet interceptor. Among other requirements, the new aircraft was to be capable of reaching speeds of Mach 2 and able to hunt down transonic bombers, while being easily maintained and capable of taking off from special public roads.
 
 
 
Saab began developing an aircraft around these specifications in the early 1950s and quickly came to the conclusion that a double delta wing design was needed in order to achieve all the requirements. However, this design was yet untried and untested, which led to the creation of the Saab 210 - a testbed aircraft which pioneered the double delta wing design.
 
 
 
Having gained the necessary insight on the performance of the double delta wing, Saab engineers transferred the newly acquired experience into the development of the actual aircraft to address the Ministry’s requirements - the J35 Draken was born.
 
 
 
The J35 Draken undertook its maiden flight in October 1955 and entered service with the Swedish Air Force in March 1960. Over 650 Drakens of various modifications would be built until the end of production, serving with Sweden until the late 1990s before being decommissioned. Apart from Swedish service, the J35 Draken also saw use with Denmark, Finland and Austria. The Austrian Air Force was the last operator to decommission the Draken in 2005, while some units are still in civilian use.

Description

GarageImage Chieftain Mk 10.jpg


The Chieftain Mk 10 is a rank VI British medium tank with a battle rating of 9.0 (AB/RB/SB). It was introduced in Update 1.71 "New E.R.A.".

The Chieftain Mk 10 is the first vehicle available in the British main research tree with APFSDS available for research, significantly improving the vehicle's gun performance once unlocked.

General info

Survivability and armour

The Chieftain Mk.10 sports identical hull armour to the earlier variants, however the turret is augmented with Stillbrew composite armour, providing near-complete frontal protection when in hull-down positioning, with the exceptions of the small area around the gun breech and a small section of visible turret ring. The Chieftain's Stillbrew package offers extremely effective protection against most kinetic rounds, with only rounds available on vehicles such as the T-80B and Type 90 able to penetrate it.

The vehicle's hull armour should be considered essentially non-existent relative to the weaponry it faces; in most cases a hull shot will result in penetration.

Armour types:

  • Stillbrew composite armour (turret front, turret ring)
  • Cast homogeneous armour (hull front, turret)
  • Rolled homogeneous armour (hull sides, hull rear, hull roof, turret roof)
  • Aluminium (side skirts)

The Chieftain Mk 10's mobility is extremely sub-par, particularly when considering the vehicles it will face regularly - such as the Leopard A1A1 or the AMX-30 Super. While the vehicle is technically capable of a maximum of 48 km/h in RB/SB, the lacklustre power and the Chieftain Mk 10's significant weight result in this speed being essentially unattainable except in on-road downhills.

As such, Chieftain Mk 10 players should not rely on their mobility for anything; rather they should make their way to positions with good visibility and attempt to maintain ranged engagements only, relying on their turret armour.

Armaments

Main armament

The L11 120mm Rifled Cannon is reasonably competitive at the Chieftain's rank, although it does suffer from a somewhat mediocre reload time. The weapon is extremely accurate, particularly once utilising the L23 APFSDS round, and performs admirably in ranged engagements. The weapon's default APDS and HESH rounds can be used to good effect against most targets, given careful aim and target selection.

Usage in battles

The Chieftain Mk 10 plays similarly to the Mk 3/Mk 5 - ideally taking long-ranged engagements from hull-down positions, or when forced into shorter-ranged engagements avoiding exposing the vehicle as much as possible. Fortunately, the Stillbrew addition on the Mk.10 significantly reduces the risks of exposing the turret, with the composite capable of deflecting most kinetic rounds it will face - although the armour package is not invulnerable to chemical rounds; some powerful HEAT rounds and most late ATGMs will easily punch through it. Augmenting the vehicle's ability further is the (researchable) access to L23 APFSDS, which significantly improves the L11's long range efficacy. Despite these improvements, the Chieftain still suffers from mediocre mobility and care must be taken to ensure one does not get engaged while the vehicle is moving, as the ability to quickly move into cover is often not an option.

Specific Adversaries

T-64B/T-80B: The Chieftain is susceptible to the T-64B and T-80B at close to medium ranges, where their highest-performance APFSDS rounds or their ATGMs are capable of punching through the Stillbrew armour. As such, when forced to engage either of these vehicles try to force mistakes by staying in cover, encouraging them to move within your firing line rather than attempting to brute-force your way through them.

Leopard 2K: The Leopard 2K is a dangerous adversary due to its speed and ability to move quickly and potentially flank the Chieftain Mk.10, as well as its 650mm HEAT round which the Stillbrew will not reliably protect against. The Leopard is however fairly easy to destroy due to its essentially non-existent armour - although don't underestimate the ability for the sharp angles to bounce rounds.

AMX-40: The AMX-40 is a threat to the Chieftain Mk.10 for similar reasons to the Leopard 2K; as with the Leopard, be wary of flanks and the power of the AMX-40's APFSDS.

Pros and cons

Pros:

  • Stillbrew composite armour makes a hull-down Chieftain essentially impervious to all but the best kinetic rounds. It is also resistant to most rank VI chemical rounds and early generation ATGMs. Due to this, the tank is a nightmare to fight with outdated tanks for many nations, as not many tanks can even scratch its turret directly to begin with
  • The L23 APFSDS round is very powerful and will have little trouble penetrating most vehicles at the Chieftain's rank
  • 10° of gun depression
  • Reasonably fast reload time for a 120mm with a base time of 9.5s and a best time of 7.5s
  • Reasonable reverse speed
  • Receives a Laser Rangefinder as a Tier 4 modification, the first British vehicle this is available on

Cons:

  • Stillbrew composite armour does not provide particularly good chemical protection against upgraded rank VI ATGM, which means, that while it can often allow Chieftain Mk 10 to ignore ATGM attacks from tanks like Begleitpanzer 57, KPz-70 or M551 and maybe even some attacks from unskilled IT-1 operator, in up-tier or against specialized rank VI ATGM tanks and tanks, which can carry advanced ATGM ( like BMP-1, BMP-1 (DDR), BMP-2, Type 89, Warrior, Etc.), the tank commander must be much more cautious
  • While turret is near invulnerable to shells with poor flight characteristics, it still retains a glaring weakspot in form of cupola, which can be penetrated and obliterated by almost any APHE, sometimes even from light tanks such as Begleitpanzer 57, resulting in full crew knockout. Because of this, Chieftain Mk 10 is usually forced to keep their enemies away, even when going to the frontline
  • Very poor mobility characteristics, much slower than most medium tanks it have to face
  • Hull armour is negligible, comprised only of Cast Homogenous armour, which means that it is even weaker, than what it looks like
  • Hull penetration will often result in ammunition detonation as ammo is strewn throughout it

History

Concept

The idea of a "universal tank" began in Britain in 1944 when Montgomery and other influential people began advocating for a more standardized tank to replace the cruiser and infantry tank classes used on the field. Efforts did not start until after World War II under the General Staff designation A45, with development starting just as the new cruiser tank Centurion started to enter military service. The A45 was cancelled in 1948 after development troubles and its inability to be used as a "universal" platform. Ironically, the Centurion proved to be a better "universal tank" platform than the A45.[1]

Development

The Centurion tank series was very successful in British and its allies' service, but the development of new Soviet armour such as the IS-3 and T-54/55 caused the British tank arms race to take another leap forward. Development on the Centurion's successor began in 1951 under the name Medium Gun Tank No. 2. The project's priority was gun and armour, but with mobility to be equal to the Centurion's and weight of fewer than 45 tons. The weight limit caused a program known as the Concept Study Programme to commence in order to find ways to keep the tank under that weight limit yet meet all the armour and firepower specifications. One of the concepts that came out was the usage of bagged charges, which was already in use on naval ships but was a new concept for tank ammunition. Thus, a gun using the bagged charge propellant system began development in 1954, along with a new specification by General Staff that the Medium Gun Tank No.2, now known as FV4201, uses a conventional four crew tank with a turret and a better gun and armour than the Centurion. Though the Conqueror heavy tank was one such response to the firepower requirement, limited production cut that to only 200 units built.[1]

The biggest bump to the firepower of the FV4201 was the recommendation of a 120 mm calibre tank cannon. Though the Conqueror used a 120 mm, the new one would incorporate more innovative features such as the bagged charges. Other design features added was the usage of a Rolls-Royce V8 engine, an auxiliary engine, an automatic gearbox, and a reclining seat for the driver. The reclining seat was a very new feature in tank design as it reduced the vehicle's hull height and thus gave it a lower profile. Leyland Motors was assigned to be the main designer for the tank despite their commitment to the Centurion production lines. The manufacturing process of the tank was decided to be cast rather than welded. In 1957, several specifications added to the FV4201 impeded its attempt to fit in the specifications. A bigger turret was designed and it mounted IR equipment for night fighting. Troops requested more frontal and turret side armour, which along with the turret change caused an increase in the tank's overall weight. A controversial decision was also made in 1957 by NATO that tanks should have multi-fuel engines. The FV4201 installed a new engine conforming to these standards in 1958, a German engine derived from a Junkers Jumo aviation engine. This extended development time since the engine compartment had to be redesigned to fit the engine, raising the total tank weight to 50 tons. The engine, designated the L60, was received with a mixed reception by the Royal Armoured Corps (RAC) and other users due to its novel features. Britain stayed as the only user of a multi-fuel engine in the Cold War as many other nations found the concept impractical and abandoned it.[1]

As the FV4201 finalized its prototype stages, General Staff sent a revised specification for it. The tank was to have the firepower of the Conqueror with the mobility of the Centurion, an armour that maximizes the protection-weight ratio, a weight limit at 45 ton with a top speed of 26 mph and an operating range of 300 miles. The first wooden prototype was made in March 1959, with full prototypes ordered in June 1959 for troop trials. Vickers-Armstrong and Royal Ordnance Factory shared the manufacturing process and the first prototypes were built in January 1960. The first two prototype FV4201 was trialled in Germany alongside their new Leopard 1. The greatest issue with the FV4201 was the engine, which caused many failures due to vibration, a result of the flawed multi-fuel concept. Trials were delayed due to lack of parts to fix broken pieces and redesigns were requested to fix problems. After a lengthy trial period in 1962, the FV4201, now named the Chieftain, was sent to the operational unit in Germany for service and combat trials. The Chieftain was finally accepted for service in 1st May 1963, despite the many faults in the design. The first deliveries of the improved and redesigned Chieftains began in mid-1965. These were the Chieftain Mk 1's, which further revealed problems with the horsepower that the Mk 2 was designed and sent in April 1966. The Chieftain Mk 3 rolled out of the production lines in September 1969, it now weighed 53 tons and the L60 engine was producing 650 hp, still underpowered for the weight. Engine failures were still frequent and left the Chieftain with a sour note until the Mk 5 variant fixed these pressing issues with a new engine and NBC protection. The Mk 5 would be the main variant of the Chieftain in British service. During its production life from 1965 to 1985, a total of 2,265 Chieftains would be built by Britain, with about 1,000 used by the British Army.[1]

Service

The first British units to receive the Chieftains was the 1st and 5th Royal Tank Regiments back during the trials. The Chieftain, despite its initial engine flaws, proved to be combat-proof and could be upgraded to fit new requirements. Some of these upgrades were the addition of composite add-on armour to fight off new anti-tank technology such as the HEAT rounds. The Chieftain earned the title "most formidable tank in the world" during the 1960's Cold War period and also redefined the specifications of a "main battle tank". Its success is due to its novel main gun and heavily sloped armour, as well as satisfactory mobility and speeds able to compete with the Leopard 1. The Chieftain stayed in use by the British Army On the Rhine on the German border with the Warsaw Pact, which caused the Soviets to in turn station their best tanks such as their T-64's against the Chieftains. The British retained the Chieftains all the way until 1997, when it was replaced by the Challenger II, initially being used in addition to Challenger I.

The Chieftain was also successful in the export market, primarily in the Middle East to the hands of Iran, Jordan, Kuwait, and Oman. Another user of the Chieftain was Israel, with Britain initially agreeing to help set up production for locally produced Chieftains. Two Chieftains were sent for trials among the Israeli Defense Force in 1967. After two years of trials and deliberation for the acquirement of the Chieftains, Britain ultimately refused to offer the Israelis the Chieftain for political reasons. The Israeli trials benefit Britain with data on desert combat with the Chieftain, however, and the refusal did jump start Israel's tank program that would become the Merkava.

Despite that, sales to the Middle East soared, with Iran being the major buyer of the Chieftains with at least 887 of mostly the MK3 and MK5 variants sent to them before their revolution in 1979. The Chieftain saw prolonged combat in the Middle East in the Iran-Iraq War, including Operation Nasr which was the largest tank vs. tank battle of the war where the Iranian Chieftains and M60A1 Pattons fought against the Iraqi T-62s. After that war, the Chieftain in Kuwait then saw combat fighting the Iraqis during their invasion in 1990. Kuwait eventually replaced their Chieftains with the Yugoslavian M-84 tanks, which are a variant of the Soviet T-72s.

The Chieftain is still in service Iran, Jordan, and Oman in varying numbers, about 100 in Iran, 350 in Jordan, and 27 in Oman. The Chieftains underwent local upgrades to keep them up to date against a modern threat, which resulted in the Iran Mobarez Chieftain upgrade.

Legacy

The Chieftain helped revolutionize tank design with its innovative features. The most important was the reclining driver seat, which allowed the tank to have a lower profile as the driver was now that highest part of the hull in tank design. It also had the most powerful NATO tank armament in service until the advent of the German Rheinmetall 120 mm, which came about two decades later. Chieftain can be considered the definitive main battle tank of the 1960s and help transition the path between second-generation main battle tanks and the third.
