Unfortunately, most of the history surrounds the flattops and accompanying task forces. Same with aircraft. The most modeled aircraft seem to be the 109's, 51's, F4U and F6F's. You see more and more variants every year because they sell. I suspect there is a market for auxilaries, albeit a smaller one. The gun platforms in whatever size and scale will always outsell the support hulls. They just don't see any recovery of tooling costs in producing them.......
