The Petya class was the NATO reporting name for a class of light
frigates designed in the 1950s and built for the Soviet Navy in the 1960s.
were the first gas turbine-powered ships in the Soviet navy. The role of these
ships was anti-submarine warfare in shallow waters. The specification was issued
in 1955 and design approved in 1956. A total of 56 ships were built in four shipyards.
Displacement was 910 tons under standard load and 1050 tons under full load. The
ship's profile saw the mass of the superstructure contained forward of midships
with low-profile funnels aft of this. A main mast was set along the aft section
of the superstructure. Power was from a CODAG (COmbined Diesel And Gas) arrangement
which paired 2 Gas turbines of 30000 horsepower with 1 Diesel unit of 6000 horsepower
- providing speeds reaching 33 knots and ranges out to 2000 nautical miles. A
three shaft machinery layout was chosen with the central shaft powered by diesel
engines for economical cruising and the two wing shafts powered by gas turbines
for speed. Gun armament was two twin 76 mm gun turrets which were controlled by
a single radar director. Anti-submarine armament consisted of four RBU-2500 anti-submarine
rocket launchers and a launcher for 400 mm anti-submarine torpedoes.

Sea Fleet, from 19 August 1982 - reclassified to trials ship with rename to OS-34.
SKR-17 was excluded from the lists of the Black Sea Fleet on 28 September 1990
