The Grisha class, Soviet designation Project 1124 Al'batros, are a series of anti-submarine corvettes built by the Soviet Union between 1970 and 1990 and later by Russia and Ukraine. These ships have a limited range and are largely used only in coastal waters. They have been equipped with a variety of ASW weapons and an SA-N-4 'Gecko' surface-to-air missile launcher. All were fitted with retractable fin stabilizers.

The designation "corvette" for these ships was a conditional adaptation as the Soviet classification was a small anti-submarine ship (Russian: Малый противолодочный корабль, romanized: Malyy protivolodochnyy korabl, lit. 'Small anti-submarine ship') (MPK). In the Russian Navy, the Grishas are expected to be partially replaced by the Steregushchiy-class corvette.

• Grisha I (1124.1) – 12 ships built between 1970 and 1974 and decommissioned by 1999
• The Grisha II class (1124P) were built for the KGB border guard and marked with P for pogranichnyi meaning "on the border". This class was built only in Zelenodolsk and Vladivostok. These ships had a second 57 mm gun mounting replacing the SA-N-4 missile system forward. 17 ships were built in the 1970s. Two were transferred to the Ukrainian Navy and some may remain in service with the Russian Maritime Border Guard.
• The Grisha III class (1124 2nd batch) were built in the late 1970s to early 1980s. These ships incorporated several small scale modifications, including a 30 mm gun and new electronics. Thirty four units were built. Two ships were in service with the Lithuanian Navy until 2009.
• A single Grisha IV class (1124K) ship was built in Zelenodolsk. This ship was a test ship for the SA-N-9 missile system and later was decommissioned.
• The Grisha V class (1124 M, 1124.4) ships were built between 1985 and 1994. This incorporated further modifications with the twin 57 mm guns being replaced by a single 76 mm gun. Thirty ships were built.
  • The Grisha V class (1124MU) ships were Ukrainian ships built after the dissolution of the Soviet Union among which is Ternopil that entered service in 2006 with the Ukrainian Navy.
  • Currently on the RF ships are being modernized "Tornado 2" combat complex for antisubmarine "Zapad" type missiles firing.^[2]
  • As of 2023, some 19 Grishas (mostly Grisha IIIs) remain active in the Russian Navy.
