🇨🇦🇺🇸 US approves Canadian-designed icebreaker for Arctic cutters
The United States has approved Seaspan’s Multi-Purpose Icebreaker design as the baseline for the US Coast Guard’s new Arctic Security Cutters, the Canadian company said on Jan 7.
Under the ICE Pact, two hulls will be built in Finland and up to four in the US, alongside full transfer of design, engineering data, and supply chains.
The Polar Class 4 vessels will displace up to 9,000 tonnes, have a 60-day endurance, a range of 12,000 nautical miles, and the capability to break ice up to 1.22 metres thick.
