Project 1241 Molniya, designated by NATO as the Tarantul class, is a series of Soviet and Russian missile corvettes. Designed in the late 1970s, the class was developed as a successor to the Project 205M Tsunami missile cutters. Development focused on providing a more seaworthy platform with higher-positioned air search radars and improved gun armament. Construction was centered at the Petrovsky, Rybinsk, and Ulis shipyards.
The initial variant, Project 1241.1, utilized a hull derived from the Pauk-class corvette and a COGOG propulsion system consisting of gas turbines for both cruising and high-speed operations. Its sensor suite included the Plank Shave radar for surveillance and target acquisition. An export version, Project 1241.RE, was distinguished by the relocation of the fire control radar to the mast and the use of the Garpun-Bal radar system.
The Project 12411 variant introduced a CODAG propulsion arrangement, combining cruise diesels with gas turbines. This version featured a redesigned superstructure and a straight lattice mast. Later developments, designated Project 1241.8 and 1242.1, integrated modern anti-ship missile systems and phased array radars. The Project 12418 variant, which uses CODAD propulsion and stealth-shaped gun turrets, is represented by Stupinets, launched at Rybinsk in July 2024 and moved to the Caspian Sea for trials in September 2025. On 25 July 2026 Ukraine's security service reported a long-range drone strike on a Project 12418 missile boat in the Caspian, mounted alongside strikes on two cargo ships and an offshore oil platform; the boat was not named publicly, and its identification rests on Stupinets being the only unit of the type stationed there.
The class has been operated by numerous navies. The Indian Navy license-produced the design as the Veer-class, while Vietnam established a domestic production line for the Project 1241.8 variant with assistance from the Almaz Central Design Bureau. Following the dissolution of the Soviet Union, ships were distributed among successor states. In March 2014, Russian forces captured four Ukrainian vessels. During the conflict in 2024, the Russian Black Sea Fleet vessel Ivanovets was sunk by uncrewed naval drones.
Other operators have included the navies of Bulgaria, Poland, Romania, Yemen, Egypt, and Turkmenistan. The German Volksmarine operated five vessels; one was transferred to the United States Navy for evaluation and later served as a museum ship. Several decommissioned vessels are preserved as museums in Germany, India, and Russia.
Ukraine's Security Service says long-range drones hit a Project 12418 missile boat, the sanctioned freighters Port Olya 2 and Begey and a Lukoil oil platform on the night of July 25, 2026. Iran says one of its sailors was killed.
