I’ve heard talk of the FRC-A, and Sentinel Class patrol boat, what’s the difference?
The FRC-A designation referred to the first revision of the original FRC design specifications which called for, most notably, a composite-hulled ship. After careful research and evaluation, the Coast Guard concluded that not only was the technology not yet mature enough to produce the conceived design, but that it would not possibly be available soon enough to meet the critical mission requirements and capability needs of the service, both now and in the foreseeable future. As such, the Coast Guard proposed a revised design specification, identified as the Sentinel Class patrol boat, through a “parent craft” acquisition strategy. Parent craft describes the use of an existing ship design that has successfully performed equivalent missions.
