The big, fast 6in-gun light cruiser: US/CL/1936

The next step is to have a big, fast 6in gun light cruiser to fit in with the rest of the extreme ships. This design is the US/CL/1936a1, as I hope to do another light cruiser which is AA-oriented. This ship has 15-6in QF guns and 12-5in DP guns, along with 36-40mm AA. The speed is extreme: 36 knots and the range pretty extreme for what I have been doing: 12,000 nm. The armor basis is 4in, and I included 12-21in TT, as well, as this is tryining to be a US Mogami (except larger).
