19 September, the Congressional Research Service has issued an update to its “Coast Guard Polar Security Cutter (Icebreaker) Program: Background and Issues for Congress” replacing an edition published on eight days earlier. You can see the latest version here. The only significant changes I see in the latest edition is reflected in table C-1 to include future year PSC funding though FY2024 and table C-2 that provides projected Procurement, Construction and Improvements (PC&I) funding through FY2024. Notably these PC&I projections are well below the $2B annually that the Coast Guard has been saying they need.
Projected PC&I totals by FY are:
- 2020: $1,234.7M
- 2021: $1,679.8M
- 2022: $1,555.5M
- 2023: $1,698.5M
- 2024: $1,737.0M
You can track the changes made between consecutive editions here.

Interestingly, the chapter related to parent design that I pointed out as an addition from September does not show as a change in the redline version and yet i can’t find the same text from the previous revision. However, I admit I may be missing it as I’m browsing on my phone – will look again once back at desktop.
On the other hand, I’m fairly sure that regardless of who won the contract the final design would have been very different from any possible parent design – this is just the way it goes when you start adapting an existing design for another operator.
