NavyRecognition is reporting the launch of the first for a class of ships being built for the Maritime Border Guards of the Federal Security Service of the Russian Federation (FSB, successor of the KGB). The ship is similar in many respect to the projected Offshore Patrol Cutter.
Named “Ocean,” she is reportedly ice strengthened with a displacement of 2,700 tons, a speed of 20 knots, a range of 12,000 miles, and a 60 day endurance. She has a hangar and flight deck, at least two RHIBs, and a 76mm gun. Unlike previous classes used by the Maritime Boarder Guards this is not an adaptation of a Navy design.
