Well, this is the vortex I didn't want to get sucked into. Warhorse nicely summarized the missile variants (although I would have forgotten the Northampton) But previous to those were the gun variants. And I am just going to major versions - there were certainly many updates that could qualify as "variants", depending on the mood of the questioner. CL? During the war, there were round bridge and square bridge variants. Then the Fargo class with the single stack. (Shall we count Atlanta IX 104 in her final days as an experimental ship with all those different ship types' upperworks?) For the CA, I guess I'm happy naming the two stack ships with one aircraft crane (round stern - Pittsburgh) and those with two (square stern - Baltimore) Then the single stack Oregon City class. For all of them, 20mm came and went, 40mm came and went, 3"50 came and went, various radar suites evolved, various aircraft handling facilities evolved, and Regulus came and went. Rick |
