The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} German bomber {{Battle-rating}}. This bomber has been in the game since the start of the Open Beta Test in Update 1.27 in the German aviation tree. In [[Update 1.69 "Regia Aeronautica"]], the S.M.79, as well as the other Italian planes in the German tree, were moved to the new Italian tree. This variant is painted in Romanian markings.

<!-- ''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.

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.

<!-- ''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)}}
 +
 
 +
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.

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.

During the pre-war period, SIAI actively tried to export the SM.79. Alessandro Marchetti argued that twin-engine planes, not three-engine, would be best for export. So, in spite of the Royal Italian Air Force’s rejection of the SM.79B bomber project, he continued work in this area, developing a prototype.
 
−
 
 
−
The SM.79B had a completely redesigned nose section. A glazed cabin for the bombardier/navigator was placed where the centrally located engine used to be. The cockpit, to improve visibility, was moved forward and raised. The dorsal “hump” was moved farther back. Also, the area of the keel was increased slightly.
 
−
 
 
−
The plane was powered by two 14-cylinder star-shaped air-cooled Gnome-Rhone 14Kfs engines with 950 hp and a metal three-bladed variable-pitch SIAI propeller.
 
−
 
 
−
The engines were placed in elongated engine nacelles, and the aeroplane was given a more streamlined design, which fully compensated for the reduction in total thrust. The aircraft’s defensive armament remained virtually unchanged: three heavy-calibre 12.7 mm Breda SAFAT machine guns, with 500 rounds per gun. One fixed machine gun was placed in the nose, and a second was located in the turret under the hump’s sliding panel. The ventral gondola was now used only for a third gun, defending the plane from attacks from the lower rear.
 
−
 
 
−
The twin-engine SM.79B was offered to Belgium, Brazil, China, Czechoslovakia, Finland, Turkey, Yugoslavia, and the Soviet Union. However, no orders from any of these countries were ever received.
 
−
 
 
−
In the spring of 1937, Iraq ordered five SM.79Bs. The aircraft for Iraq were equipped with A.80 RC.41 engined with a takeoff power of 1030 hp. The third, fourth, and fifth SM.79Bs had larger cockpit windows. In early 1938, the Italian crews ferried the aircraft to the customer. All of these planes were eventually destroyed in 1941 during the rebellion in Iraq.
 
−
 
 
−
The largest order for the twin-engine SM.79B was placed by the country of Romania. In autumn of 1937, the Romanians requested 24 of the aircraft equipped with IAR K14-II engines with a power of 900 hp. (A licensed version of the Gnome-Rhone engine, produced in Romania.)
 
−
 
 
−
When compared with the Iraqi planes, the Romanian version had several differences: the mobile 7.92mm Browning FN machine gun with rotary magazine and 350 rounds of ammunition (mounted in the nose) and various equipment modifications. In 1938, these aircraft entered service with two squadrons of the Forţele Aeriene Regale ale Romaniei (Royal Romanian Air Force).

So, in spite of the Royal Italian Air Force’s rejection of the SM.79B bomber project, he continued work in this area, developing a prototype.
 
−
 
 
−
The SM.79B had a completely redesigned nose section. A glazed cabin for the bombardier/navigator was placed where the centrally located engine used to be. The cockpit, to improve visibility, was moved forward and raised. The dorsal “hump” was moved farther back. Also, the area of the keel was increased slightly.
 
−
 
 
−
The plane was powered by two 14-cylinder star-shaped air-cooled Gnome-Rhone 14Kfs engines with 950 hp and a metal three-bladed variable-pitch SIAI propeller.
 
−
 
 
−
The engines were placed in elongated engine nacelles, and the aeroplane was given a more streamlined design, which fully compensated for the reduction in total thrust.
 
  
−
The aircraft’s defensive armament remained virtually unchanged: three heavy-calibre 12.7 mm Breda SAFAT machine guns, with 500 rounds per gun. One fixed machine gun was placed in the nose, and a second was located in the turret under the hump’s sliding panel. The ventral gondola was now used only for a third gun, defending the plane from attacks from the lower rear.

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 twin-engine SM.79B was offered to Belgium, Brazil, China, Czechoslovakia, Finland, Turkey, Yugoslavia, and the Soviet Union. However, no orders from any of these countries were ever received.

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.

In the spring of 1937, Iraq ordered five SM.79Bs. The aircraft for Iraq were equipped with A.80 RC.41 engined with a takeoff power of 1030 hp. The third, fourth, and fifth SM.79Bs had larger cockpit windows. In early 1938, the Italian crews ferried the aircraft to the customer. All of these planes were eventually destroyed in 1941 during the rebellion in Iraq.
+
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 largest order for the twin-engine SM.79B was placed by the country of Romania. In autumn of 1937, the Romanians requested 24 of the aircraft equipped with IAR K14-II engines with a power of 900 hp. (A licensed version of the Gnome-Rhone engine, produced in Romania.)
 
−
When compared with the Iraqi planes, the Romanian version had several differences: the mobile 7.92mm Browning FN machine gun with rotary magazine and 350 rounds of ammunition (mounted in the nose) and various equipment modifications. In 1938, these aircraft entered service with two squadrons of the Forţele Aeriene Regale ale Romaniei (Royal Romanian Air Force). "

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.

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.

Pros and cons

Pros:

  • Excellent HEAT round for its rank, able to penetrate the upper glacis plate of the Tiger II
  • Above average mobility, able to secure crucial positions or even flank the enemy
  • Neutral steering
  • Able to hull-break light vehicles
  • Small silhouette
  • Incredible gun depression

Cons:

  • Poor armour, sides able to be penetrated by heavy machine guns, and even rifle-calibre bullets behind the tracks
  • Has hull-break
  • No MG to destroy light fences that can fuse your HEAT shells
  • Slow gun traverse, makes aiming in CQB or moving target harder
  • Vehicle reverses slightly when firing, forcing you to reacquire range of target after every shot
