The Albatros class (Russian: Альбатрос; NATO reporting name: Grisha-I) was a series of 12 large anti-submarine corvettes built by the Soviet Union between 1970 and 1974. These ships had a limited range and were used only in coastal waters. They were equipped with a variety of ASW weapons and an SA-N-4 surface-to-air missile launcher. All were fitted with retractable fin stabilizers. Seven were still in service in 1997, though all had been stricken by 1999. Russian type designation was Malyy Protivolodochnyy Korabl (Small Anti-Submarine Ship).
The Grisha II class (1124P) were built for the KGB border guard, These ships had a 57 mm gun replacing the SA-N-4 missile system. 12 ships were built in the 1970's. Two were transferred to the Ukrainian Navy and around ten are in service with Russia.
The Grisha III class (1124M) were built in the late 1970s to early 1980s. These ships incorporated several small scale modifications, including a 30 mm gun and new electronics. About 20 remain in Russian service. Two ships are in service with the Lithuanian Navy.
A single Grisha IV class (1124K) ship was built. This ship was a trials ship for the SA-N-9 missile system.
The Grisha V class (1124 ME) ships were built between 1985 and 1994. This incorporated further modifications with the 57 mm guns being replaced by a single 76 mm gun. About 28 ships remain in the Russian Navy. Ternopil (U209) entered service in 2006 with the Ukrainian Navy.
