Submarines in trouble in the Arctic due to ice

Here’s a climate news story right up my alley. 

This said, we’ve been surfacing under ice since 1958. This is the 26th arctic exercise to date. There’s nothing new here — other than the ice is thicker than predicted by climate models. 

25 Mar 2018 – “US Nuclear Submarine Gets Stuck In Arctic Ice, “Deterring The Russians,” reads the headline.

According to fort-russ.com, the U.S. nuclear submarine USS Connecticut was unable to rise to the surface in the Arctic due to the thickness of the ice.

Another submarine missile carrier, the USS Hartford, managed to break through the ice, but received significant damage.

A Google search reveals that both vessels are Los Angeles-class nuclear-powered submarines providing the US Navy with a lethal combination of stealth and firepower. Their primary mission is to hunt and kill enemy ships and submarines.
They both cruise the Arctic Ocean with two-ton 20-foot-long torpedoes capable of destroying an enemy submarine in an instant.

The ice where they attempted to surface was reportedly only 40 cm (16 inches) thick. Russian submarines  can break ice up to 2.5 meters (8 ft) thick.
