Project 23550 patrol ship

Project 23550 is a class of armed icebreaking patrol ships with two vessels currently under construction for the Russian Navy at Admiralty Shipyards in Saint Petersburg, Russia ("Arktika" Type, Russian: шифр «Арктика», lit. 'codename Arctic').[7][8][9] Two ships have been ordered from the Admiralty Shipyards in 2016.[10] The ships are designed to patrol the Russian territorial waters and exclusive economic zone in the Arctic.

During the launching ceremony of the lead ship, it was announced that two additional ships of slightly revised design would be built for the Border Service of the Federal Security Service of the Russian Federation by Vyborg Shipyard ("Ermak" Type, Russian: шифр «Ермак», lit. 'codename Yermak').[7][8][2]

Design
Model of the project 23550

Project 23550 patrol ships have a planned displacement of 6,800 tons, a length of 114 metres (374 ft 0 in) and a draught of 6 metres (19 ft 8 in).[9] The ships will be equipped with two Project 03160 Raptor class patrol boats, a Ka-27 helicopter and small hovercraft. The core crew is planned at 60 with accommodation for an additional 50 mission specialists. Armament will include a 76-millimeter (3 in) naval gun (some sources state a 100 mm (3.9 in) naval gun)[11] and 3M-54 Kalibr anti-ship missiles in the Club-K container variant.[3][4][12]

Project 23550 will have a diesel–electric power plant with four 3,500-kilowatt (4,700 hp) Kolomna 28-9DG generating sets consisting of 16-cylinder 10D49 diesel engines driving alternators produced by Ruselprom. In addition, the ships will have two auxiliary diesel generating sets with Kolomna diesel engines and Ruselprom alternators. While the early concept featured ABB Azipod azimuthing propulsion units, the final design has two conventional shaft lines, propellers and rudders. The 6,300-kilowatt (8,400 hp) propulsion motors will be produced by Ruselprom.[1][6] The ships will have an endurance of 70 days and a range of 10,000 nautical miles (19,000 km; 12,000 mi) at economic speed of 10 knots (19 km/h; 12 mph). Their maximum speed is 18 knots (33 km/h; 21 mph).[4][12]

The vessels are strengthened for navigation in ice-covered arctic seas according to the Russian Maritime Register of Shipping ice class Arc7.[4][9] They are designed to break ice up to 1.7 metres (5 ft 7 in) thick.[12]

Think tank Global Security pointed out several similarities between the 23550 design and Norway's Svalbard class, and Canada's Harry DeWolf class.[9] All three class are of approximately the same displacement, capable of transitting similar depths of ice and have similar size crews, with room for mission specialist. The 23550 class is, however, much more heavily armed.

In 2020 it was announced that the Russian Navy would begin sea trials to test the installation of module containers on patrol vessels permitting such ships to carry significantly upgraded armaments tailored to different missions. The containers were envisaged to carry various weapons including sonars and torpedoes or anti-ship and cruise missiles.[13]
