Coast Guard Polar Security Cutter (Polar Icebreaker) Program: Background and Issues for Congress [Updated June 7, 2021] [open pdf - 2MB]
From the Introduction: "This report provides background information and issues for Congress on the Polar Security Cutter (PSC) program--the Coast Guard's program for acquiring new PSCs (i.e., heavy polar icebreakers). The Coast Guard's proposed FY2022 budget requests $170.0 million in procurement funding for the PSC program. The issue for Congress is whether to approve, reject, or modify the Administration's FY2022 procurement funding request for the PSC program, and, more generally, whether to approve, reject, or modify the Coast Guard's overall plan for procuring new polar icebreakers. Congress's decisions on this issue could affect Coast Guard funding requirements, the Coast Guard's ability to perform its polar missions, and the U.S. shipbuilding industrial base."
