The '''Stridsvagn m/39''' was ordered in 1939 by KAF, that saw how new tank designs were shaping the battlefield, and the m/38 was considered to be too weak in terms of armour. The m/39 would have been a minor upgrade to its predecessor, with upgraded armour and other minor changes. AB Landsverk was against it however, since the m/38s hull was not able to sustain the increased weight. In the end, the turret was slightly modified, it included a new fire control system, as well as a lever steering system which was more favourable. While the m/38 was named L-60-S, the Stridsvagn m/39 was designated L-60-S/II.

This vehicle shouldn't be confused as a tank destroyer (TD) by its designation, TD in this case stands for '''T'''witch '''D'''rop. It has the same exact gameplay style as the [[Strv m/39]], with access to good mobility and excellent firepower in the form of a good APDS shell. The turret's armour is increased to 50 mm of thickness, the gun depression is great with -15 degrees but the hull armour and cramped crew compartment make the tank extremely vulnerable to even autocannon fire.

Strv m/39 is a continued design from the Strv m/38. In 1939, KAF had started discussions about ordering 20 new Strv m/38's to improve the strenght of the armoured company and, seeing the international way of desinging tanls eguipped with cannons, they reguested that new desings of Strv m/38 should have improved the armour by making it thicker to combat this threat. AB Landsverk was agains it since the construction of the L-60-S (Strv m/38) would not be able to handle this reguest of the additional weight the new armor would add to it. And because of this made them a contract that there would be small chanches to the L-60-S, mainly modifications to the turret adding room for an additional machine gun to be placed. Additionally there would be a new control system for the tank. Strv m/38 had the old system using a steeeing wheel, the new tank would use lever steering which was more favourable. When the contract was signed for these new tanks 19 December 1939 the new and improved tank got the designation L-60-S/II and was supposed to be delivered in middle of October 1940, but trouble and delays for the 37mm Bofors cannons delayd it until the spring 1941 which at time tanks had improwed a lot and there was a demand for thicker armour. They wanted to increase the frontal armour of the L-60-S/II from 15 to 50 mm but this would only happen in case of combat that it would be added as add-on armour to the tanks. But during exercise the tanks would not have this additional armour on them to not wear out the wehicles. L-60-S/II would get the designation Strv m/39 by the army.

Description

The Stridsvagn m/39 TD is a gift rank Swedish light tank with a battle rating of (AB), (RB), and (SB). It was introduced during Update "Starfighters" as a reward for watching War Thunder streams on Twitch.tv along with a unique skin for the vehicle. This vehicle shouldn't be confused as a tank destroyer (TD) by its designation, TD in this case stands for Twitch Drop.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • Still effective in up-tiers, since it has access to a high-penetrating APDS shell with an amazing 105 mm penetration and high velocity
  • Amazing -15 degrees gun depression means that it can adapt different terrains very well
  • Fast reload, up to 3.1 seconds with an ACE crew.
  • Decent turret armour, offering up to 35mm at the front and with sloping for increased protection.
  • Fast top speed up to 45 km/h
  • Is a small target

Cons:

  • Only 3 crew members
  • Armour is inadequate to resist high-penetrating shells, for example a Pz.II can penetrate it frontally
  • Slow turret traverse speed with 11.2°/s
  • Very average reverse speed of -7 km/h
  • 5-8 mm roof armour can be penetrated by common aircraft such as ones with 12.7 mm M2, and He 112 A-0
  • Purple stripes may be eye-catching, decreasing its concealment

History

Strv m/39 is a continued design from the Strv m/38. In 1939, KAF had started discussions about ordering 20 new Strv m/38's to improve the strenght of the armoured company and, seeing the international way of desinging tanls eguipped with cannons, they reguested that new desings of Strv m/38 should have improved the armour by making it thicker to combat this threat. AB Landsverk was agains it since the construction of the L-60-S (Strv m/38) would not be able to handle this reguest of the additional weight the new armor would add to it. And because of this made them a contract that there would be small chanches to the L-60-S, mainly modifications to the turret adding room for an additional machine gun to be placed. Additionally there would be a new control system for the tank. Strv m/38 had the old system using a steeeing wheel, the new tank would use lever steering which was more favourable. When the contract was signed for these new tanks 19 December 1939 the new and improved tank got the designation L-60-S/II and was supposed to be delivered in middle of October 1940, but trouble and delays for the 37mm Bofors cannons delayd it until the spring 1941 which at time tanks had improwed a lot and there was a demand for thicker armour.

But during exercise the tanks would not have this additional armour on them to not wear out the wehicles. L-60-S/II would get the designation Strv m/39 by the army.

Strv m/39 was in use till 1957.
