Production of the craft lasted from 1970 until 1985 in Leningrad. The Aist class
prototype was built in 1970, and the type entered production in Leningrad in 1975.
In total, 20 ships were built from 1970 to 1985 under this project.
ship's capacity was designed for two medium or four amphibious tanks. The total

range of 300 miles, autonomy of 5 days. The main power plant of this ship consisted
of two DT-4 gas turbine engines with a total capacity of 32000 hp, driving the
superchargers and four propellers. The pontoons and the cargo hold of the ship
ensured its positive buoyancy in any situation. At full speed, the ship is controlled
by air rudders located behind the propellers, and at low speeds - by jet rudders
with air intake from axial blowers.
