We are excited to welcome USCGC Polar Star (WAGB 10) to our Harbor Island Shipyard at Vigor Marine Seattle. As the United States’ only active heavy icebreaker, Polar Star plays a critical role in supporting national security, scientific research and operations in some of the world’s harshest environments. Our skilled workforce looks forward to supporting the vessel during its availability and getting it back into service.
