Very short explanation:
The modification’s goes Stock mixed belt → “HE” belt → “AP” / SAP belt, so progressing through the line changes how the gun performs against tanks and aircraft.
Sweden only has Frankenbelts™
All nations get these “Pure” HE/AP autocannon belts, including similar-performing guns like the US/German/Soviet 37mm (even Soviet 25mm AA guns.) Sweden doesn’t. Swedish 40mm vehicles are stuck with mixed, mislabeled belts that ruin AA consistency and limit usability. Vehicles like the Lvkv 42 suffer especially due to limited ammo, making these bad belts a major handicap.
Why is Sweden the only exception to this? Its not like specifically 40mm Swedish HE and AP rounds are superior, And you can just adjust the SAP-HE belt if its too strong. But why this-?
Needed Fixes
The best way to fix the current state of the Swedish 40mm Gun Carriers is to:
Fix the belt layout so it matches other nations Ease of use and reliability, as is only fair:
Belts should look like this:
Stock belt:
AP / HE / AP / HE
AP belt:
AP / AP / AP / AP
AA belt:
HE / HE / HE / HE
SAP-HE Belt:
SAP-HE / AP / SAP-HE / AP
or Just
SAP-HE / SAP-HE / SAP-HE / SAP-HE
Fix The Incorrect ammunition for the 40mm Lvakan 48 (40mm Bofors L/70)
Ammunition choices should look like this:
Lvkv 42 Ammo values should be changed:
Remove slhpgr m/43
Remove slsgr m/36C
The Lvakan 48 would only use these munitions in training for cheaper costs due to less , so having them be the main rounds is innacurate to war thunder.
Add “slsgr m/484”
Round Mass: 0,983kg
Velocity: 980 - 1005~ m/s
HE charge: 0,115kg Hexotonal (RDX)
VEAK 40 Ammo values should be changed:
Remove slhpgr m/43
Remove slsgr m/36C
No documented proof that Lvakan 48s used Earlier ammunition at this time.
Add “slsgr m/484”
Round Mass: 0,930kg
Velocity: 1000 - 1005~ m/s
HE charge: 0,115kg Hexotonal (RDX)
Add “Slpprj m/??”
Round Mass: 0,977kg
Velocity: 1005 - 1025~ m/s
About Same performance as the Leopard 40/70 or AMX-13 DCA 40, AP-T
Add Slpprj m/49 (APDS-T (24mm Core) )
Round Mass: 0,705kg
Velocity: 1100 - 1200~ m/s
120mm~ // 100m // 90° Angle
Greatly Reduce // Remove muzzle flash present on the 40mm - 20mm Guns With a Muzzle Hider
List of guns in War thunder with Flash hiders: (Probably more)
- 20 mm Oerlikon 204 GK
- 20 mm GAI C01
- 2 cm Flak 38
- 20 mm Scotti-IF 20/70 mod.41
- 23 mm AZP-23
- 3.7 cm Flak 36/37
- 37 mm M1939 (61-K)
- 40 mm Bofors
- (Includes: 40mm Automatic Gun M2, Lvakan m/36, M266 Automatic cannon, Lvakan m/48, 40 mm Mle51 T1)
- 57 mm Bofors L/70
All these changes would Bring the Swedish 40mm Guns to the same capability as the others in-game. And reducing the muzzle flash issue for all 40mm / 37mm / 20mm Guns would help SPAA all around with both targeting in 3rd person and to reduce visability to enemy planes.
