Naval News reports that the world’s largest icebreaker, “Arkika,” has completed sea trials. This is the first of five Project 22220 nuclear powered icebreakers.
This class is quite remarked for its number of ships, their size, their speed, their power, and for their small crew size.
These are dual displacement icebreakers designed to operate in rivers as well as the Arctic Ocean, using huge amounts of ballast water.
- Displacement:33,530 t (33,000 long tons) (dwl) 25,540 t (25,140 long tons) (min)
- Length: 173.3 m (569 ft) (overall), 160.0 m (525 ft) waterline
- Beam: 34 m (112 ft) (maximum), 33 m (108 ft) waterline
- Draft: 10.5 m (34 ft) (dwl) 8.65 m (28 ft) (minimum; operational)
- Propulsion: three shafts, total 60 MW (80,461 HP)
- Speed: 22 knots.
- Crew: 75
Even larger Project 101510 ships, capable of breaking up to 4-metre-thick (13 ft) ice, are under construction. They will be 209 metres (686 ft) in length, with a beam of 47.7 metres (156 ft) with four shafts providing 120 megawatts (161,000 hp).
