Coast Guard capacity concerns about the cutter adaptation

The National Security Cutter is treated as the likely replacement-frigate starting point in this part of the conversation.

His concern is that a Navy adaptation could reduce Coast Guard capacity and introduce new changes into an established hull. The passage expresses that concern without confirming the eventual replacement frigate's design.
