Lvkv 42 (fm/49) Is Largely flawed and needs to be re-worked

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.

  1. 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.

  1. 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.

  1. 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)

Hull/Internal

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-

Sammanfattning












TL:DR

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.

It is also worth noting the now about four year old issue of the ammunition for this vehicle (and the VEAK 40)

Although i wont cover this in detail here as its both all over the forum and on reddit and has a bug report.

This is everything i have to cover on this issue so far, any further information or bug reports on this issue will be added in the main post when i or others create them.

Sometimes I’m surprised by the devs’ negligence in their duties.

This cant exactly be blamed on the devs as When the vehicle was added there was only a handful of images of the vehicle. So there had to be some Creative imagination

But I don’t think this vehicle was top secret; you can simply go to a museum where there’s one, at least you can see how the gunners’ sights are positioned.

+1 for a remodel

It isnt out on display but arsenallen has it and they cannot currently display it for foreclosed reasons, But gaijin had visited swedish museums to record engines and look at tanks when they were Making the swedish TT, So They Did probably visit arsenallen at some Point

And the gunners sights on the current whole Lvkv 42 is not mounted on the tank sadly

Dang. 3-4 years of research is impressive! Gaijin PLS do this

Great work. Always sad to see vehicles put into the game as a complete ahistorical mess and then destined to stay that way because the devs don’t care enough.

Actually got a responce from the Armour museum in sweden from this quest of mine when i shared my info with them.

I thaught that was pretty cool^^

"The Email"

Translation:

“Thanks alot,”

“Some of this information we have already obtained from other sources, but not all. All small pieces of the puzzle are therefore very valuable.”

"We have a few vehicles in the collection that we have not brought to light for various reasons and Lvkv 42 is one of these - behind the scenes, however- we have been looking for information to try to straighten out a lot of the question marks that exist.
Lvkv 42 is a very interesting wagon and the only one that has been preserved of all the thoughts and plans that were had from the end of the 40s until the mid-60s.
There is a little, but not much written about the Vehicle."

Im mostly thankful people are actually happy enough and care enough about this vehicle to come here and share support for it to be fixed^^

Thanks all that has stopped by and read it and dropped a reply^^ Its very appreciated o7

Hopefully, this information will be used and this vehicle will be corrected as quickly as possible.

How about they just fix the ridiculous muzzle flash while deciding if they’ll redo the model?

That would be a benefit.

Also ammunition supply, even with the ammunition box, this thing’s capacity seems to be really small. If it gets a buff in onboard supply would be great, even if it’s not “historically accurate”. They tend to take liberties with vehicles for balance reasons all the time.

Highly doubt devs will work on this when they said their main focus is on top tier and they won’t be adding new WWII or older era vehicles. But fingers crossed

hehe “technically” This is a cold war vehicle lol

The low ammunition supply always seemed dubious for both the LvKv 42 and the L-62 ANTI II.

Especially the LvKv 42, which has the RoF of two standard Bofors guns but not even half the ammunition of a M19A1

And then there’s the super slow traverse of both the ANTI and the Lvtdgb m/40, which is just a truck with a Bofors gun. Really curious where Gaijin got the 21°/s from.

Here is a video of the L-62 Anti II, And the turret traverse seems to be very light.

As for the Lvtgb m/40, Im not sure its much faster than it is in-game sadly-

Meanwhile the L/70 mount is pretty damn fast.

And considdering the Lvkv 42 Turret drive is linked to the engine output and turret to a electrical motor, I think its reasonable its equally as fast.

SPAA traverse speed is kind of like the reload time on many vehicles, a balancing factor. At least on hand cranked vehicles where it is highly sped up on certain ones.
Data wise, the Lvtdgb m/40 uses the standard m/38 mount, I believe. This mount will traverse 6° with each revolution of the crank, and elevate 4° with one revolution of the elevation crank. That gives it about 3.5 crank revolutions per second to achieve 21°/s traverse. Not too unrealistic, in my opinion. Though I do not know how much effort is needed, either.
