U.S. Coast Guard Icebreaker Frees Antarctic Cruise Ship From Ross Sea Pack Ice

The operation underscores reliance on the nation’s only heavy icebreaker as it supports Antarctic logistics for the National Science Foundation.

Overview

  • The Australian-owned Scenic Eclipse II requested assistance after becoming trapped in pack ice roughly eight nautical miles from McMurdo Sound, according to the Coast Guard.
  • USCGC Polar Star made two close passes to break the vessel free, then escorted it about four nautical miles to open water.
  • The rescue took place during Operation Deep Freeze 2026 and coincided with Polar Star’s 50th commissioning anniversary.
  • Polar Star is the United States’ only active heavy icebreaker and departed Seattle in November for its 29th Antarctic deployment.
  • Coast Guard video shows the cutter cutting a navigable path through the Ross Sea toward the immobilized cruise ship, which can carry up to 228 passengers and 176 crew.
