The heavy nuclear-powered missile cruiser Pyotr Veliky will conduct anti-submarine and air defense exercises in the Barents Sea, the press service of the Northern Fleet reported on Tuesday.

“Today, the heavy nuclear missile cruiser Pyotr Veliky entered the Northern Fleet’s combat training ranges in the Barents Sea to work out planned combat training missions,” the press service said in a statement.

“For several days, the crew of the cruiser will continue to work out interaction with naval aviation – anti-submarine and search and rescue helicopters Ka-27 of the Air Force and Air Defense Army of the Northern Fleet,” the fleet said.

Last week, the Pyotr Veliky completed a number of planned combat training tasks in the Barents Sea, including working out interaction with the crews of nuclear submarines, the military reported.

“Pyotr Veliky” is the world’s largest operating non-aircraft-carrying strike warship with a nuclear power plant. Designed to destroy large surface targets, provide integrated air defense and anti-submarine defense of warship formations.
