The Muravey-class is the NATO reporting name for a class of hydrofoil patrol boats built for the Soviet Navy. ^[1]

The Soviet designation was Project 133 Antares. ^[2]

Design

The ships were designed as coast guard patrol vessels and were built in the More Shipyard in Feodosiya for the Black Sea Fleet. They are powered by gas turbines in contrast to diesel engines used for most other Soviet fast attack craft to achieve higher speeds.

Ships

11 units were built for the Soviet Navy between 1979 and 1992, while 1 unit was completed in 1993 for Ukraine. ^[3]

• 8 were operated by the Russian Border guard
• 4 were operated by the Ukrainian Sea Guard

Variants

• Project 133: basic hydrofoil
• Project 133RA: stealth version (unrealized)
