Description

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.

Introduced in Update 1.97 "Viking Fury", the Strv m/39 plays much like the Strv m/38: it is fast, manoeuvrable, and has excellent firepower. While it lacks APHE, it has access to a powerful APDS shell with insanely good penetration values for such a low BR tank. The new turret has increased armour, up to 50 mm thickness. Its gun handling is also great, with a good turret traverse rate and excellent gun depression of -15 degrees. However the hull has very light armour, and the small crew makes the tank vulnerable to even autocannon fire.

Usage in battles

The Strv m/39 has a similar gameplay style to the Strv m/38. It's a fast light manoeuvrable tank with excellent firepower and adequate protection for its battle rating. Unlike the predecessor m/38, the m/39 got a more heavily armoured frontal turret with 50 mm thickness, making it an excellent hulled down vehicle. The Strv m/39 like its predecessor has an excellent gun depression and is able to look over hills without exposing itself too much to the enemies.

The Strv m/39 has an APDS round at a very low BR, which gives it a good advantage in long distance engagements and against more heavily armoured vehicles. As such, it can make a very reliable sniper, even when brought to higher BRs. While the APDS has a high penetration, it has mediocre post-penetration damage, making it hard to take out the spaced out crew members with a single hit in big vehicles like the LVT(A)(1) or the T-28. This forces the player to aim properly at crew positions and modules on the tanks, giving the enemy time to return fire, unless the gunner and commander are immediately eliminated.

The Strv m/39 is good at getting quickly to locations, making it an excellent vehicle to employ hit-and-run and ambush strategies with, as well as being useful as an objective taker . The best part of the Strv m/39 is being able to utilize hilly terrain on certain maps to its advantage while in a hull down position, making it a dangerous target to face in the hands of a good player.

Pros and cons

Pros:

  • Still effective in up-tiers, since it has access to a high-penetrating APDS shell with an amazing 105mm 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 A0

History

The Strv m/39 is a continued design from the Strv m/38. In 1939, KAF had started discussions about ordering 20 new Strv m/38s to improve the strength of the armoured company and, seeing the international way of designing tanks equipped with cannons, they requested that new designs of Strv m/38 should have improved armour by making it thicker to combat this threat. AB Landsverk was against it since the construction of the L-60-S (Strv m/38) would not be able to handle this request of the additional weight the new armour would add to it. And because of this made them a contract that there would be small changes to the L-60-S, mainly modifications to the turret adding room for an additional machine gun to be placed. Additionally, there would a new control system for the tank, Strv m/38 had the old system using a steering 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 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 37 mm Bofors cannons for the tanks delayed it until Spring 1941 which at time tanks had improved a lot and there was demand for thicker armour again. 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 onto the tanks. But during exercise the tanks would not have this additional armour on them to not wear out the new vehicles. L-60-S/II would get the designation Strv m/39 by the army.

The Strv m/39 was in use till 1957.
