Description
The TIS MA is a gift rank III Soviet twin-engine fighter
with a battle rating of 3.7 (AB/SB) and 4.3 (RB). It was introduced during Update 1.95 "Northern Wind" in the Operation F.R.O.S.T. event.

Armaments
Offensive armament
The TIS MA is armed with:
- A choice between two presets:
- 2 x 37 mm NS-37 cannons, wing-mounted (75 rpg = 150 total) + 2 x 20 mm ShVAK cannons, nose-mounted (150 rpg = 300 total)
- 2 x 45 mm NS-45 cannons, wing-mounted (50 rpg = 100 total) + 2 x 20 mm ShVAK cannons, nose-mounted (150 rpg = 300 total)
Suspended armament
The TIS MA can be outfitted with the following ordnance:
- Without load
- 2 x 100 kg FAB-100 bombs (200 kg total)
- 2 x 250 kg FAB-250M43 bombs (500 kg total)
- 2 x 500 kg FAB-500 bombs (1,000 kg total)
- 8 x RS-132 rockets
- 8 x RBS-132 rockets
Defensive armament
The TIS MA is defended by:
- 1 x 12.7 mm Berezin UB machine gun, dorsal turret (200 rpg)

Pros and cons
Pros:
- Ludicrously powerful armament layouts with decent ammo capacities
- Both the 37 mm cannons and 45 mm cannons have high muzzle velocity are quite accurate
- Firing the guns barely slows the aircraft down
- Reasonable manoeuvrability for a twin-engined fighter bolstered by leading-edge slats
- Decent speed, but lower than most fighters it will encounter
- Acceptable acceleration for a twin-engined fighter
- All armaments centred in or near the nose, resulting in little need for convergence adjustments, except for long-distance shots
- Can mount bombs and rockets for ground-pounding
- Premium rewards
Cons:
- Slower than contemporary aircraft
- Lack of bulletproof glass makes the pilot prone to snipes, also vulnerable to head-on attacks
- Extremely prone to fires
History
The TIS A (and the improved MA) were designed to a 1938 specification for a heavy fighter - but work did not begin until 1940 due to resources being devoted to the I-180 and SPB projects.
The TIS A was an all metal monocoque monoplane with a very heavy forward facing armament of some mix of 2 x 37mm, 2 x 20mm cannon; and 2 x 12.7mm UB + 4 x 7.62mm ShKAS machine guns, or 6 x 7.62mm ShKAS machine guns - sources vary on the exact nature of armament for the prototype[1][2]. The single rear gunner had 2 ShKAS machine guns - 1 mounted to fire from a dorsal position, the other mounted to shoot through a ventral hatch. It was fitted with Mikulin AM-39 engines, but these had protracted development problems - they were unreliable and vibrated above 5000m altitude.
By 1942 flight testing showed several problems, and a major redesign was conducted - radiators were moved to the wings, the machine guns in the nose were replaced by 2 x ShVAK 20mm cannon, and 2 x 45mm 11P guns were fitted in the wing roots. The gunner's 2 x ShKAS were replaced by a single 12.7mm UBT machine gun. Engine reliability was not improved, so AM-38F engines (as fitted to Il-2's) were fitted instead - and these had much lower output resulting in predictably lower performance, especially at higher altitudes due to the AM-38's single stage supercharger optimised for lower altitudes.
This configuration was renamed the TIS-MA.
Flight testing of the TIS-MA from June-September 1944 found it performed as expected with the new engines - being generally disappointing at altitude. Calculations showed much better performance if the desired AM-39's could be fitted. However fate intervened - Polikarpov died on 30 July of stomach cancer, and when the TIS-MA crashed on 15 September it spelled the end of the program - his design bureau was being shut down and none of the others could or would take it on.
