The P 4-class torpedo boat, Soviet designations Project 123-bis and Project 123-K, commonly called the Komsomolets class (Russian: Комсомолец, a male member of the Komsomol), were Soviet aluminum-hulled torpedo boats. They were armed with twin heavy machine guns and two 450 mm (17.7 in) torpedoes. A large number of them were exported to allied states such as North Vietnam and China. They saw service in a variety of armed conflicts including World War II, the First Taiwan Strait Crisis, the Vietnam War and the Turkish Invasion of Cyprus.

The P 4 torpedo boats consisted of two primary types; the Project 123-bis (B-123) type with 12.7-millimetre (0.50 in) machine guns, and the Project 123-K (K-123) type with added radar and 14.5-millimetre (0.57 in) machine guns.
