The {{PAGENAME}} is an excellent aircraft for pilots who like to perform multiple roles without having to switch up aircraft. Possessing options to carry up to 5,000 lbs in bombs, 133 unguided rockets or five 20 mm autocannons with a total of 2,350 rounds of ammunition in what is effectively a "hot rod" of the jet world allows pilots to maximize their playstyle.

== General info ==
 +
=== Survivability and armour ===
 +
<!-- ''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 armour of the Ikv 103 is between 18.5 mm to 5 mm of thickness. This armour shouldn't be considered as survivable since every round you face will most likely penetrate and destroy most of what's left inside the tank. The thin side-armour has the occasional ability to result in overpenetration, but any frontal attack usually has enough force to activate most shell fuses. The tank is also incredibly weak against chemical rounds and aerial attacks due to the hull break featured on the vehicle. It is heavily recommended to avoid any form of damage since even artillery fire has the possibility of guaranteed destruction. Due to this low survivability, taking the maximum amount of ammunition isn't something to frown upon. Thanks to the short length of the round, as well as compact storage, ammunition explosions are quite rare.
 +
 
 +
=== 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=190|rbMinHp=133}}
  
Though the manoeuvrability suffers when fully loaded, this jet attacker operates well at mid and lower altitudes, especially when unloading bombs and rockets on ground-based targets. The Skyhawk's air-to-air capabilities are not forgotten; however, as in actual usage, the missiles and internal 20 mm autocannons were more for defensive purposes or for taking out targets of opportunity. With the sheer amount of rockets when loaded, especially the Mighty Mouse variants, it is best to fire them off in salvos to ensure maximum damage inflicted.  
+
The Ikv 103 sports a good engine with a fairly high RPM giving it a lot of torque for climbing a lot of obstacles and average terrain. Although the top speed never exceeds 50 km/h, the Ikv 103 cruises comfortably around 40-45 km/h on a straight line and 25-35 km/h on uneven terrain, depending on the driving level and modules unlocked, no matter the surface below it. The vehicle finds no issue traversing snowy and sandy terrain thanks to the low weight and good track surface, but struggles in deep waters due to the low chassis it sports. The reverse rate of the Ikv 103 is also quite good at 11 km/h. Even if this speed can't hold a candle to the regular speed the 103 has, the reverse rate is still enough to safely peek over hills and reverse back into cover before getting fired upon.
  
This aircraft's nickname is "Scooter" for a reason, though not the fastest aircraft in the battle, with its petite size and massive payload, it is not uncommon for the {{PAGENAME}} to scoot behind enemy lines and rain down destruction on ground targets before anyone realizes what is going on. Though small in size, the Skyhawk should not be underestimated and considered a significant threat.

=== Main armament ===
 +
<!-- ''Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: <code><nowiki>{{main|Name of the weapon}}</nowiki></code>. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.'' -->
 +
{{main|kan Ikv (105 mm)}}
  
== General info ==
+
The Ikv 103 is outfitted with a 105 mm cannon firing heavy shells with a reload of 10-13 seconds depending on crew qualifications. This cannon is unusually short for its calibre, firing heavy shells with low-velocity. Although the early psgr m/49 lacks significant penetration and post-penetration damage, the later slpsgr m/65 HEAT-FS round packs up to 400 mm of penetration, easily penetrating anything it sees with devastating results. This later shell features a higher velocity than the previous round, as well as more explosive filler making the post-penetration much deadlier than before. The gun is aimed manually without the help of electrical equipment, resulting in a slow traverse rate. At maximum, the gun traverses at 8° per second, resulting in many deaths at closer ranges. This makes the gun most effective at medium ranges, where the traverse is ideal, and the shell velocity isn't crucial. It should be noted that the incredible gun depression allows the Ikv 103 to fire from extreme angles allowing it to safely engage targets without the risk of overexposing the tank, something which becomes incredibly useful to increase the vehicles survivability.

=== 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.''-->
 
 
The {{PAGENAME}}, designed to be a light-weight attack aircraft was half the weight of the Navy's design spec requirements. This initial weight savings meant that the plane did not have to skimp on pilot protection. Since the primary role of the aircraft is as an attacker, the pilot protection from the front and the underside is critical. From the front, the windshield portion of the canopy contains 50 mm bulletproof glass. Protective armour from the ground or naval based targets comes in the form of a 2.54 mm steel "tub" which the pilot's seat is situated in. The protective shield surrounds the pilot on all four sides (front, back, left and right) and makes up for most of the floor panelling, leaving room for the controls to go through. While the pilot is not invulnerable, the armour will provide a buffer for lighter calibre fire or shrapnel effects from missiles. The pilot does remain vulnerable to fighter aircraft approaching from above the cockpit.
 
 
There are three fuel tanks in the aircraft of which the two in the wings are non-self-sealing and pose a fire hazard if they catch on fire, however, the fuel tank situation directly behind the pilot is self-sealing.
 
 
* 50 mm bulletproof glass
 
* 2.54 mm Steel-plated "tub"
 
* Self-sealing fuel tank behind the pilot
 
* Non-self-sealing fuel tanks in the wings

The Ikv 103 is a nimble vehicle with a small silhouette compared to its peers. The lightweight and powerful gun set it apart from other vehicles at the battle rating. The general playstyle can be compared to the Jpz 4-5 found in the German tech tree. This playstyle is a more aggressive spin on tank destroying than usual, where the vehicle has to make use of positioning rather than frontal survivability. The Ikv 103 can't use common sniping locations very effectively since any form of enemy retaliation will destroy the vehicle completely. Instead, the 103 needs to drive full speed to various locations where enemies are unlikely to expect danger. Although this playstyle requires a lot of map knowledge, the reward is quite high for a successful flank, thanks to the devastating cannon the Ikv 103 carries. Thanks to the light vehicle weight and strong engine, the Ikv 103 is also able to climb a lot of obstacles, something that helps a lot when fighting on bad terrain. However, maps that lack terrain entirely cripple the 103's performance quite significantly, since the tank cannot hide, resulting in a lot of face-to-face engagements, which the Ikv 103 almost always lose.
The {{PAGENAME}} while designated by the U.S. Navy as an attacker can work as a multi-role aircraft. Though the variety of armament leans heavily to the attacker side, this aircraft also has a fighter side which can feel more like a hotrod compared to some of the other fighters out there such as the [[F-4C Phantom II|F-4]] coming in at 14-tonnes more massive.
 
 
 
;Attacker
 
[[File:A-4B an trn 26 004.png|400px|thumb|right|Zuni rockets streaking towards their target.]]
 
The Douglas Aircraft Company built the {{PAGENAME}} from the ground up to be a small, fast and effective as an attack aircraft. While conventional wisdom would dictate that a larger aircraft would be necessary to carry enough suspended ordnance into battle to be effective, the Skyhawk shatters that myth. With only three hardpoints to attach ordnance to, specialized racks can extend the number of suspended weapons which the aircraft can carry. For instance, if using this aircraft to take out a mobile vehicle or anti-aircraft artillery, strapping on 18 x 250 lb bombs provides an opportunity to hit targets which may spread out or to divide ordnance between different clusters of targets. When attacking more heavily armoured targets or bases, the {{PAGENAME}} can choose to load up on 5 x 1,000 lb bombs or a single 2,000 lb bomb which creates considerable damage against ground targets.
 
 
 
Though bombs do a considerable amount of damage where they land, they are not the end-all answer to ground attack. Unguided rockets provide another option to the attacker-role of the aircraft. This aircraft has the option of loading up on 133 FFAR Mighty Mouse or 28 Zuni unguided rockets. When the pilot selects to fire these rockets in salvo mode, they have effectively turned their rockets into a large calibre autocannon which will not overhead or jam and continue to fire off rockets until the rocket tubes deplete of their ordnance. A salvo of Mighty Mouse rockets can also be extremely effective against aircraft or helicopters which may have a hard time getting out of the way when fired at from shorter distances. On domination maps, a salvo of rockets can make quick work of aircraft attempting to capture a runway.  Bullpup rockets are another option; however, with only three loaded at a time, it is essential to be selective with the targets. To help with stabilizing the {{PAGENAME}} in a dive and while lining up targets, fuselage-mounted airbrakes can assist in preventing speed build up and stabilize the aircraft, however, once exiting an attack point, it is important to retract the airbrakes to allow for the aircraft to gain speed.
 
 
 
;Fighter
 
 
 
Typically the {{PAGENAME}} was not used as a fighter; however, it carried armament which allowed it to defend itself or take on targets of opportunity. Always at its disposal is two 20 mm autocannons each with 100 rounds, however, these won't last too long in an extended engagement. Other options which allow the aircraft to flex its offensive muscles include AIM-9B Sidewinder missiles or suspended 20 mm gun pods. The AIM-9B provides the Skyhawk with a bit more reach allowing it to hit aircraft which may be faster or out of range of the guns. Typically, when launched from less than a mile away, the missile does not track to the target and instead fly off.  For those pilots who enjoy fighting with aircraft guns, then the option to attach gun pods may be the way to go. Whether it is a single centerline gun pod or the addition of two more on each of the wing pylons, each suspended gun pod each contain 750 rounds of 20 mm ammunition.
 
 
 
Due to the diversity of weapons options afforded to the {{PAGENAME}} and their various configurations, pilots can customize their payloads to meet both their playstyle and missions. For those who want to unload the maximum damage against ground targets can choose solely to load up on bombs or rockets, while those opting for air-to-air can choose missiles and guns. Some pilots may want to take a smaller ground-attack load while affording some air-to-air protection with missiles. There is no right or wrong selection; it all depends on the fighting style of the pilot.

At a time when military aircraft were becoming more substantial in size to hold larger engines, more weapons, essential fuel and new technology, Douglas Aircraft's concept of the A-4 Skyhawk seemed counter-intuitive. The A-1 Skyraider, while a potent aircraft was starting to age out of the service as faster jets began to supplant the propeller-driven attacker. In the early 1950s, the U.S. Navy began its search for the next generation attacker and put out a requirement for an attacker with a maximum cost of $1 million and a maximum empty weight of 20,000 lbs (9,071 kg) and could carry enough ammunition to at least compete with the older but beefy A-1.
 
  
Ed Heinemann, a designer at Douglas Aircraft Company, responded with the XA4D-1 attack aircraft. Contrary to conventional wisdom, Heinemann's design focused on an attack aircraft which would be minimal in size and weight along with being a simple aircraft to maintain. Douglas Aircraft succeeded in winning the contract and what became known by nicknames such as "Scooter" or "Bantam Bomber", the XA4D-1 (later changed to A-4) was a winning solution to the Navy's needs. The resulting attack aircraft came in at just over $850,000 each while weighing half of what was the Navy's original specification, owing to weight savings with the wings, being as short as they were, there was no need for them to fold to save space while stowed on an aircraft carrier. "Scooter" was an appropriate nickname for the A-4 as its original prototype set a world speed record in 1955 with a speed of 695.163 mph (1,118.756 km/h).

The [[Ikv 72|Infanterikanonvagn 72]] was a project started in 1949 by Sweden for an assault gun. The intended role of this vehicle was to support the infantry in the attack, replacing towed artillery guns. The design was to be small, and of light weight, around 6 tons. This was to reduce costs so a larger amount could be produced. The first prototype from Landsverk, completed in 1950, was armed only with three machine guns. This was insufficient, and it was re-armed with a 75 mm cannon, the same gun from the [[Strv m/42 EH|Strv m/42]]. It was a small, lightly armoured vehicle, with a casemate superstructure housing the 75 mm gun. It had a crew of 4, and it was open topped. Starting in 1956, the Ikv 72 was upgraded to the Ikv 102 standard. This upgrade added an armoured roof for the crew compartment and a 105 mm gun replaced the 75 mm gun. The Ikv 102, in turn, was upgraded to the Ikv 103 standard. The Ikv 103 featured an improved engine, the Volvo B42 engine. The air intake was moved to grills on the rear of the vehicle, instead of through the crew compartment.
  
The A-4 though small in size, did not differ much in design from other military aircraft of the day. The wing was a low-mounted delta shape which had single forge spars which spanned to both wingtips for extra strength. Tricycle configuration for the landing gear allowed the nose to remain relatively low for excellent pilot visibility mainly when operating on the deck of an aircraft carrier. A single turbo-jet engine mounted at the rear of the aircraft was fed by two air intakes located just behind the cockpit on each side of the fuselage. Offensive weapons for this aircraft consisted of two 20 mm Browning-Colt Mk12 Mod 3 autocannons, each one located in a wing root. Only 100 rounds are available for each gun. Still, a single fuselage centerline hardpoint and a hardpoint under each wing allow for utilisation of a wide variety of missiles, rockets, bombs and gun pods.

In 1949, the procurement division of the Swedish army placed an order for the development of a light assault self-propelled gun to substitute the [[Sav m/43 (1946)|Sav m/43]] SPG. Three companies took on the work: AB Landsverk took on the development of the platform, Volvo was responsible for the powertrain, and Bofors for the armament. In fact, three versions of the vehicle for different purposes were planned at first: one with a 75 mm cannon, a machine-gun-equipped modification, and also a special one that was intended for the deployment of specific weaponry, such as flamethrowers and rocket launchers. Thus, a light (merely eight tonnes in all), tracked infantry-support vehicle was produced, with an open cabin and bulletproof armour.
  
At the start of the Vietnam War, the A-4 Skyhawk was the primary light bomber for the Navy. A total of 542 A-4Bs were built and delivered to the Navy. Upgrades over the A-4A consisted of improved navigation equipment and flight control systems. AGM-12 Bullpup missiles were also a new weapon for this aircraft. The Skyhawk also utilised the AIM-9B Sidewinder missiles; however, these were mostly used as a defensive weapon and rarely for offensive purposes.  
+
In 1952, a cannon-equipped version, under the designation the Ikv 72 (short for "infanterikanonvagn", meaning "cannon-equipped infantry-support vehicle" in Swedish), was put into service. A little later, the SPG's were re-equipped with 105 mm howitzers and the cabin was retrofitted with a roof, which could protect the crew from bullets and shrapnel. This modification received the designation Ikv 102. Meanwhile, the Swedish army ordered another series of the vehicle with an upgraded chassis to allow installation of a new air-cooled engine, while the gun and the armour remained the same as the Ikv 102's. This new version was designated Ikv 103. The Ikv 102 and 103 SPGs remained in use by the Swedish army until the mid-1970s, when they were replaced with the [[Ikv 91]] SPG.
 
 
The A-4 is a rugged little attack aircraft which remained in service with both the U.S. Navy and United States Marine Corps for over 20 years before being retired. However, more than sixty years after initial operations began, the Skyhawk is only now still in service with the Brazilian Navy.

Description

GarageImage Ikv 103.jpg


The Infanterikanonvagn 103 is a rank III Swedish tank destroyer with a battle rating of 4.0 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

General info

Survivability and armour

The armour of the Ikv 103 is between 18.5 mm to 5 mm of thickness. This armour shouldn't be considered as survivable since every round you face will most likely penetrate and destroy most of what's left inside the tank. The thin side-armour has the occasional ability to result in overpenetration, but any frontal attack usually has enough force to activate most shell fuses. The tank is also incredibly weak against chemical rounds and aerial attacks due to the hull break featured on the vehicle. It is heavily recommended to avoid any form of damage since even artillery fire has the possibility of guaranteed destruction. Due to this low survivability, taking the maximum amount of ammunition isn't something to frown upon. Thanks to the short length of the round, as well as compact storage, ammunition explosions are quite rare.

Mobility

Game Mode Max Speed (km/h) Weight (tons) Engine power (horsepower) Power-to-weight ratio (hp/ton)
Forward Reverse Stock Upgraded Stock Upgraded
Arcade 58 12 8.8 190 286 21.59 32.5
Realistic 53 12 133 150 15.11 17.05

The Ikv 103 sports a good engine with a fairly high RPM giving it a lot of torque for climbing a lot of obstacles and average terrain. Although the top speed never exceeds 50 km/h, the Ikv 103 cruises comfortably around 40-45 km/h on a straight line and 25-35 km/h on uneven terrain, depending on the driving level and modules unlocked, no matter the surface below it. The vehicle finds no issue traversing snowy and sandy terrain thanks to the low weight and good track surface, but struggles in deep waters due to the low chassis it sports. The reverse rate of the Ikv 103 is also quite good at 11 km/h. Even if this speed can't hold a candle to the regular speed the 103 has, the reverse rate is still enough to safely peek over hills and reverse back into cover before getting fired upon.

Armaments

Main armament

Main article: kan Ikv (105 mm)

The Ikv 103 is outfitted with a 105 mm cannon firing heavy shells with a reload of 10-13 seconds depending on crew qualifications. This cannon is unusually short for its calibre, firing heavy shells with low-velocity. Although the early psgr m/49 lacks significant penetration and post-penetration damage, the later slpsgr m/65 HEAT-FS round packs up to 400 mm of penetration, easily penetrating anything it sees with devastating results. This later shell features a higher velocity than the previous round, as well as more explosive filler making the post-penetration much deadlier than before. The gun is aimed manually without the help of electrical equipment, resulting in a slow traverse rate. At maximum, the gun traverses at 8° per second, resulting in many deaths at closer ranges. This makes the gun most effective at medium ranges, where the traverse is ideal, and the shell velocity isn't crucial. It should be noted that the incredible gun depression allows the Ikv 103 to fire from extreme angles allowing it to safely engage targets without the risk of overexposing the tank, something which becomes incredibly useful to increase the vehicles survivability.

Usage in battles

The Ikv 103 is a nimble vehicle with a small silhouette compared to its peers. The lightweight and powerful gun set it apart from other vehicles at the battle rating. The general playstyle can be compared to the Jpz 4-5 found in the German tech tree. This playstyle is a more aggressive spin on tank destroying than usual, where the vehicle has to make use of positioning rather than frontal survivability. The Ikv 103 can't use common sniping locations very effectively since any form of enemy retaliation will destroy the vehicle completely. Instead, the 103 needs to drive full speed to various locations where enemies are unlikely to expect danger. Although this playstyle requires a lot of map knowledge, the reward is quite high for a successful flank, thanks to the devastating cannon the Ikv 103 carries. Thanks to the light vehicle weight and strong engine, the Ikv 103 is also able to climb a lot of obstacles, something that helps a lot when fighting on bad terrain. However, maps that lack terrain entirely cripple the 103's performance quite significantly, since the tank cannot hide, resulting in a lot of face-to-face engagements, which the Ikv 103 almost always lose.
