Tupolev MTB-2

Tupolev MTB-2 ( _ru. Морской Тяжелый Бомбардировщик — Heavy Naval Bomber), also known as ANT-44, was a four-engine flying boat designed in the Soviet Union in 1935. The first of two prototypes flew on 19 April 1937 with T. V. Ryabenko and D. N. Ilyunskiy at the controls. In 1938, the original 810 hp (604 kW) Gnome-Rhône Mistral Major 14Kdrs engines were replaced with Tumansky M-87s of 840 hp (627 kW) each.Shavrov 1994.]

The second prototype, designated ANT-44bis or ANT-44D was an amphibious aircraft powered by four M-87A engines of 950 hp (709 kW) each. With I. M. Sukhomlin at the controls, the aircraft was used to set a number of world records in its class:
* 17 June 1940: altitude of 7,595 m (24,918 ft) without payload
* 17 June 1940: altitude of 7,134 m (23,406 ft) with 1,000 kg (2,205 lb) payload
* 19 June 1940: altitude of 6,284 m (20,617 ft) with 2,000 kg (4,409 lb) payload
* 19 June 1940: altitude of 5,219 m (17,123 ft) with 5,000 kg (11,023 lb) payload
* 28 September 1940: maximum speed of 277.4 km/h (150 knots, 172 mph) over 1,000 km (540 nm, 621 mi) with 1,000 kg (2,205 lb) payload
* 7 October 1940: maximum speed of 241.9 km/h (131 knots, 150 mph) over 1,000 km (540 nm, 621 mi) with 2,000 kg (4,409 lb) payload

ANT-44D piloted by I. M. Sukhomlin saw limited operational use in the Black Sea region in 1941-1943 in bomber and transport roles.
