The Project 885M Severodvinsk (Yasen)-class nuclear-powered guided-missile submarine (SSGN) Krasnoyarsk (K 571) has departed Severodvinsk for its first set of sea trials in the White Sea.

Photographs on social media showing Krasnoyarsk leaving the harbour area confirms the submarine's departure on 26 June.

Krasnoyarsk is the fourth Project 885 (and the third 885M) submarine under construction at Sevmash Shipyard and is predicted to join the Pacific Fleet, joining the SSGN fleet comprised of mostly Project 949A Oscar II-class boats.

Krasnoyarsk had been captured on satellite imagery the week prior to heading out to sea being degaussed in the harbour area. Other imagery shows the submarine undergoing final preparations alongside another Project 885M – likely to be Novosibirsk
