The Udaloy class, Russian designations Project 1155 Fregat and Project 11551 Fregat-M (Russian: Фрегат, 'Fregat' meaning Frigate), are series of anti-submarine guided missile destroyers built for the Soviet Navy, seven of which are currently in service with the Russian Navy. Twelve ships were built between 1980 and 1991, while the thirteenth ship built to a modified design, known as Udaloy II class, followed in 1999. They complement the Sovremennyy-class destroyers in anti-aircraft and anti-surface warfare operations.
