The Graivoron Buyan-M-class corvette of project 21631 built for the Black Sea fleet sailed out for the first time for factory running trials, the Defense Ministry said.

The Black Sea fleet is actively developing into a self-sufficient and balanced force.

Buyan-M-class corvettes of project 21631 received new capabilities. Naval robotic mines joined their stock of arms. The smart munitions independently identify the type of sea craft and destroy it only after identification.
