Kalma-3 (Project 1791R)

The Kalma-3 (Project 1791R) is a Soviet air-cushion landing craft designed for high-speed amphibious transport of troops and light military hardware. It utilizes a pressurized air cushion to glide over water, ice, and flat terrain, allowing it to land forces on unprepared shorelines. The vessel represents a specialized class of Soviet hovercraft developed for rapid tactical deployment.

Developed during the late Cold War by the Soviet Navy, the Project 1791 'Kalma' class was designed to enhance amphibious assault capabilities in littoral zones. The Kalma-3 was constructed in the mid-1980s and entered service to conduct coastal logistics, troop transport, and assault exercises. Following the collapse of the Soviet Union, the vessel was transferred to the Russian Navy, where it served in a limited capacity before eventually being retired from active duty.
