Friends and family watch Coast Guard Cutter Polar Star crewmembers moor the ship up to the pier at Base Seattle, March 16, 2018, after returning from a 107-day Antarctica deployment.
The Polar Star is one of the largest ships in the Coast Guard and one of the world's most powerful non-nuclear ships.
The Polar Star crew departed Seattle Nov. 30, to assist in the annual delivery of operating supplies and fuel for NSF research stations in Antarctica. Operation Deep Freeze is the logistical support provided by the U.S. Armed Forces to the U.S. Antarctic Program.
Polar Star is 399-feet long, 13,500 tons, 84-feet wide, has a 34-foot draft (the same as an aircraft carrier), 75,000 horse power and nine engines (six diesels, three jet-turbines).
Polar Star is homeported in Seattle and carries approximately 150 crewmembers, 1.5 million gallons of fuel and enough food stores to last one year in the ice should it be necessary.
