The Lvkv 42 (fm/49) has long been something of a mystery. Over the past three to four years, I have dedicated myself to researching it in depth. With the help of various museums and individuals—most notably Blockhaj, renhanxue, and the staff at Arsenalen here in Sweden—I have been able to piece together a far more complete picture of what the Lvkv 42 actually was.
Based on this research, I can state immediately that the Lvkv 42 as it currently appears in War Thunder is severely flawed and inaccurately modeled. Roughly 60–70% of its internal components are missing. While the turret is partially correct in terms of external appearance, it still lacks important features such as the shell-ejection funnel. Internally, however, the turret is largely incorrect.
In this post, I will go through what the model gets right, what it gets wrong, and what is entirely missing.
So, without further delay, let’s begin.


There is a few differences in the turret design, And i can admit they almost got it right, but i will list some differences.
- Turret control. The turret was not controlled via mechanical crank, it was electronically operated by help of a controller linked to servos in the turret, this is to make the reaction time faster.

- No ejection chute. The gun lacks a Ejection port for its casings. War thunder partly features the Ejection shute for the casings but they just lead into the hull at the moment.
- Missing gunsights. The Vehicle currently lacks A gunsight but the blueprint shows a connector from the mount of the gun to the viewing port for the gunner.
(This also implies the crew sits to far up. And hence shouldnt pop their heads above the shrappnel shielding as they currently are)
The turret traverse system is directly linked to the engine, The turret elevation is likely controlled by a Electroc motor in the turret as there is no visable mechanical link to the elevation motor as far as i have found.
Here is the comparrison images.
NOTE: I dont have exact knowledge on what each internal component works or what they do. But i have some speculation of some parts.
If anybody has any engineering compitence or any other perspective on what everything does, you are welcome to suggest it-

After several years of research and collaboration with museums and knowledgeable individuals, it is clear that the Lvkv 42 (fm/49) is currently significantly misrepresented in War Thunder. While the external turret shape is partially accurate, the vehicle as a whole is missing the majority of its internal systems, with an estimated 60–70% of components absent or incorrectly modeled.
Key turret systems are either wrong or missing entirely, including the electronic servo-driven turret control, the proper shell-ejection chute, and the gunsight assembly, which also results in incorrect crew positioning to be to high up. Internally, both the turret traverse and elevation mechanisms are inaccurately portrayed, with evidence indicating an engine power transfer- traverse system and electrically powered elevation, rather than the simplified implementations currently shown.
