Coast Guard Cutter Healy, the largest ship in the U.S. Coast Guard at 420 ft., is powered by a diesel-electric power plant generating enough power for the medium icebreaker to bash its way through Arctic ice up to 8 ft. thick!

Machinery technicians aboard Healy, assigned to the Main Prop division, stay busy maintaining and repairing the ship’s four 12-cylinder Main Diesel Engines which turn the ships four electric generators.

The Healy and its crew are currently circumnavigating North America promoting U.S. interests along the U.S. and Russia maritime boundary line, conducting Coast Guard missions and supporting scientific research throughout the Arctic.
