The Congressional Research Service has once again updated their look at the Polar Security Cutter (heavy icebreaker) program. (See the latest version here.)

I have reproduced the one page summary below.

As expected, the FY2024 budget includes $125M to purchase a US built commercially available icebreaker, presumably the Aiviq since it is the only one that meets the criteria.

The budget as enacted includes $20M for procurement of a Great Lakes Icebreaker (GLIB). The request for this item was $55M.

There was nothing in the enacted budget for the Polar Security Cutter program because the first two ship have already been funded but construction has yet to begin on the first ship, so there is no need to fund the third in FY2024.

There is a requirement to report on the possibility of reviving the Polar Sea,

In addition, within 120 days of the date of enactment of this Act, the Coast Guard is directed to provide a report that assesses the viability of reactivating Coast Guard Cutter Polar Sea. The report shall include an analysis of the material condition of the hull and cost and timeline estimates for a full overhaul of the vessel, including the renewal of the cutter’s propulsion, mechanical, electrical, communication, and support systems.

Summary

Required number of polar icebreakers. A 2023 Coast Guard fleet mix analysis concluded that the service will require a total of eight to nine polar icebreakers, including four to five heavy polar icebreakers and four to five medium polar icebreakers, to perform its polar (i.e., Arctic and Antarctic) missions in coming years.

Current operational polar icebreaker fleet. The operational U.S. polar icebreaking fleet currently consists of one heavy polar icebreaker, Polar Star, and one medium polar icebreaker, Healy. A second Coast Guard heavy polar icebreaker, Polar Sea. Polar Sea, suffered an engine casualty in June 2010 and has been nonoperational since then. Polar Star and Polar Sea entered service in 1976 and 1978, respectively, and are now well beyond their originally intended 30-year service lives. The Coast Guard plans to extend Polar Star’s service life until the delivery of at least the second Polar Security Cutter (PSC; see next paragraph).

Polar Security Cutter (PSC). The Coast Guard PSC program aims to acquire four or five new PSCs (i.e., heavy polar icebreakers), to be followed at some later point by the acquisition of new Arctic Security Cutters (ASCs) (i.e., medium polar icebreakers). The Navy and Coast Guard in 2020 estimated the combined total procurement cost of the first three PSCs in then-year dollars as $2,673 million (i.e., about $2.7 billion). The procurement of the first two PSCs is fully funded. The Coast Guard’s proposed FY2024 budget requested $170.0 million in continued procurement funding for the PSC program. The Coast Guard’s proposed FY2025 budget requests no procurement funding for the PSC program. The Coast Guard originally aimed to have the first PSC delivered in 2024, but the ship’s estimated delivery date has been delayed repeatedly and may now occur no earlier than 2028. Another potential issue concerns the accuracy of the PSC’s estimated procurement cost, given the PSC’s size and internal complexity as well as cost growth in other Navy and Coast Guard shipbuilding programs. The PSC’s estimated procurement cost per weight is roughly half that of the Navy’s LPD-17 Flight II and LHA amphibious ships. These amphibious ships are equipped with expensive combat system equipment that is not included in the PSC design, but whether this would account for all of the difference in cost per weight between the PSC design and the two amphibious ship designs is not clear. If substantial cost growth occurs in the PSC program, it could raise a question regarding whether to grant some form of contract relief to the PSC shipbuilder.

Commercially available polar icebreaker (CAPI). The Coast Guard’s proposed FY2024 budget requested $125.0 million in procurement funding for the purchase of an existing commercially available polar icebreaker (CAPI) that would be modified to become a Coast Guard polar icebreaker. The Coast Guard’s proposed FY2025 budget requests no procurement funding for CAPI, but the Coast Guard’s FY2025 Unfunded Priorities List (UPL) includes an item for $25.0 million in procurement funding for the ship.

Great Lakes icebreaker (GLIB). The Coast Guard’s proposed FY2024 budget proposed to initiate a new procurement program for procuring a new Great Lakes icebreaker (GLIB) that would have capabilities similar to those of Mackinaw, the Coast Guard’s existing heavy Great Lakes icebreaker. The Coast Guard’s proposed FY2024 budget requested $55.0 million in initial procurement funding for the ship, and the Coast Guard’s FY2024 UPL included an item for an additional $20.0 million in procurement funding for the ship. The Coast Guard’s proposed FY2025 budget requests no procurement funding for GLIB, but the Coast Guard’s FY2025 UPL includes an item for $25.0 million in procurement funding for the ship.
