The '''Priz class''' (Project 1855) is a type of [[deep-submergence rescue vehicle]] (DSRV) operated by the government of [[Russia]].  There are known to be at least five vessels of the class, several of which were involved in the failed rescue attempt when the submarine {{ship|Russian submarine K-141|Kursk||2}} sank on 12 August 2000. The [[Russian language|Russian]] word "Priz" (“приз”) means "prize".

== Specifications ==
The [[titanium]]-[[submarine hull|hulled]] vessels are {{convert|13.5|m|ftin}} long, {{cvt|3.8|m|ftin}} wide and {{cvt|4.6|m|ftin}} high, with a [[Displacement (ship)|displacement]] of {{convert|55|t|LT|lk=on}}. Capable of operating at depths up to {{cvt|1000|m}}, they have a range of {{convert|21|nmi|lk=in}}, at a top speed of {{convert|3.3|kn|lk=in}}. 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 {{convert|50|kg}}.

According to a report on Russian television (Vesti, on Rossiya channel, 7 August 2005), the Project 1855 Priz vessel was designed by the [[Lazurit Design Bureau]] of [[Nizhny Novgorod]], and four modifications were made: ''AS-26'' (1986), ''AS-28'' (1989), ''AS-30'' (1989), and ''AS-34'' (1991).

==Operations==
The Priz class is thought to be operable either crewed or uncrewed with a [[Electric battery|battery]] endurance of three hours. Between 2006 and 2016, an upgrade of the class to improve its navigational, search and life-support ability was conducted.

The Priz submarines are carried by ''Pionier Moskvyy''-class submersible support ships (Project 05360/05361), which can carry up to two of the submarines. The ships are equipped with special equipment to deploy a Priz in rough seas.

==List of boats==
There are currently four Priz vessels operating.
