Serpukhov, the Russian small missile ship, was significantly damaged by a fire on Sunday in the Baltic Sea exclave of Kaliningrad, according to an anonymous Ukrainian security source cited by RBC Ukraine on Monday.

Newsweek has not been able to corroborate the report independently.

The Buyan-M class corvette reportedly incorporates stealth technology and has a vertical launching system for either Kalibr or Oniks anti-ship cruise missiles.

In September 2023 the Russian state media reported that Serpukhov performed a successful launch of a cruise Kalibr missile in the White Sea, successfully hitting a a “coastal target.”

In March, Russian and Ukrainian media reported that another vessel, Kapitan Lobanov, sank near the city of Pionersky in the same area of the Baltic Sea, which has been described as a “NATO Lake” following the expansion of the alliance in response to Moscow’s aggression in Ukraine.
