Coast Guard Polar Security Cutter (Polar Icebreaker) Program: Background and Issues for Congress [Updated December 10, 2018] [open pdf - 2MB]
"The Coast Guard Polar Security Cutter (PSC) program, previously known as the polar icebreaker (PIB) program, is a program to acquire three new heavy polar icebreakers, to be followed years from now by the acquisition of up to three new medium polar icebreakers. The Coast Guard wants to begin construction of the first new heavy polar icebreaker in FY2019 and have it enter service in 2023. The PSC program has received about $359.6 million in acquisition funding through FY2018, including $300 million provided through the Navy's shipbuilding account and $59.6 million provided through the Coast Guard's acquisition account. The Coast Guard's proposed FY2019 budget requests $750 million in Coast Guard acquisition funding for the program."
