[PROJECT S.N.A.I.L.] ZiS-43

The GAU (Russian: Главное артиллерийское управление, English: Main Artillery Directorate) set forth a requirement for an anti-aircraft vehicle using a 37 mm AA gun on a ZiS-42 half-track on 14 November 1942. The requirements stated that it was to have armour protection for the engine and cabin, and also was to have an armoured shield for the gun mount. The requirements also gave a maximum weight of 6.5 tons; the vehicle was developed by the ZiS factory in Moscow and was given the designation ZiS-43.

The ZiS-43 utilized the ZiS-42M half-track chassis with a 37 mm 61-K anti-aircraft gun mounted on the flat bed at the rear. The front half of the weapon mount was protected by armoured shields, the engine compartment was uparmoured, and so was the cabin. All the added armour protection gave the vehicle a weight of 8.75 metric tons. In addition to the weapon system and increased armour, the vehicle included other minor changes in comparison to the ZiS-42 including redesigned grills for increased engine cooling. The sides, as well as the top, of the engine compartment received armoured hatches for ease of maintenance. The cabin was redesigned in order to give the driver more comfortable working conditions, as on other models the driver's position was known to be incredibly uncomfortable.

The prototype went to trials on 15 December 1942 after driving 380 km to Gorohovets Artillery Proving Grounds from the factory. From the 19th to the 23rd of December, the ZiS-43 prototype was driven over five hundred km. Problems arose with the cooling of the vehicle, with the engine overheating twice during trials and the cabin getting as hot as 50°C. Due to the weight of the ZiS-43, a maximum speed of 35 km/h was achieved on roads and only 19.5 km/h on dirt roads. The average speed was 29.3 km/h on roads and the fuel consumption was as high as 110 litres per 100 km on dirt roads and still a low minimum of 90 litres per 100 km on more favourable terrain. During firing trials a number of other issues were revealed; the headlights would shatter upon firing due to changes in pressure and the high center of gravity caused accuracy issues due to instability.

The ZiS-43 never entered service thanks to its disappointing performance during trials, leaving production at only one prototype. For an anti-aircraft vehicle such armour was seen as an unnecessary burden, and the program was subsequently cancelled. After the cancellation of the program the armour of the ZiS-43 prototype was removed, returning it to its original state as a ZiS-42M.

HP: 550
AMMO: 5 per clip, 260 in total per ammo type
RELOAD SPEED: 0.5 seconds
SPEED 38 km/h forward, 9 km/h backwards
SEATS: 3, driver, gunner and "loader"
WEAPONS: 37mm autocannon
GUN MOVEMENTS: 85 degrees of gun elevation, -5 degrees of gun depression
NOTE: because of the gun platform leaning a bit forward, you gain -3 degrees more of gun depression (-8 degrees) but lose 3 degrees of gun elevation (82 degrees)

-open top vehicle, anything can knockout your crew
-can be harm by heavy damage type
-only has 50% resistance to heavy damage type
-kinda slow for a big vehicle
-bad reverse speed
-the windows can break, so you can shoot there and snipe the driver

SHELL DAMAGE: 30
EXPLOSION DAMAGE: 17

SHELL DAMAGE: 259
EXPLOSION DAMAGE: 0

this whole few mods will be prototypes, so not super exciting in new vehicles that were in service, anyways, at least the gun was in service, so that's cool

oh yeah, uh not a lot of SPAAs left for ussr :( so that's a shame, rank 2 is the last rank with ww2 Spaas

ALSO, i skipped the btr-152a cuz it's a 50s vehicle, i do only 1930s-1945, so yeah

WORKING AUTO HEADLIGHTS, WILL TURN ON WHEN IT'S NIGHTTIME, WORKS WITH DAY/NIGHT MUTATOR
