 Deep-Submergence Rescue Vehicle AS-28
Project 1855 / Priz class
 
  
 

In the early 1980s, the Lazurit Central Design Bureau developed a Project 1855 for the Prize rescue submarine of the third generation, chief designer E.V. Krylova. Apparatus of this type are designed to rescue crews from emergency submarines by docking to emergency exits of submarines. In total, 4 units were built for this project.

The titanium hulled vessels are 13,5 m long, 3,8 m wide and 4,6 m high, with a displacement of 55 tonnes. Capable of operating at depths up to 1000 metres, they have a range of 21 nautical miles (39 km), at a top speed of 2,3 knots. With a crew of four, they can stay submerged for up to 120 hours, but with the crew and a full complement of 20 passengers aboard this is reduced to 10 hours. The Priz vessels are equipped with manipulators that can lift up to 50 kg. The Priz rescue submarines are carried by submersible support ships of Project 05360 or Project 05361, which can carry up to two of the submarines. The ships are equipped with special equipment to deploy Priz in rough seas.

Deep-submergence rescue vehicle AS-18 laid down in January 1982 at the Krasnoe Sormovo Shipyard named after A.A.Zhdanov, Gorky (yard No.1), launched on 10 December 1985, commissioned on 12 August 1986 and was assigned to the Pacific Fleet.

From July 2006 to April 2008, AS-28 was modernized according to the Project 18551.

In January 2016 the rescue submarine was transferred to the Black Sea Fleet.

Now in service.
