Exactly. So, the first builder do the detailed design, and they can (try to) export it, as Babcock themself did with Vard7 80 and 90 OPV designs.
We remember Arrowhead 120 design, a significantly modified derivative of Vard 7 110 design. Vard 7 110 is now on build for USCG, and Babcock supported the detailed design, and therefore has some know-how.
But they eventually moved to Danish design, Arrowhead 140. It was a good decision, so that Babcock won the bid. But, Babcock lost the chance to design a ship by their own. If any T32 to be newly designed, Babcock shall try to do it nearly from scratch. If T32 is more and more Vard-7 like, they will do better (because they have such experience). If more a full-fat frigate like, it will be very difficult for Babcock, and hence they will be importing designs from abroad.
