One of the ideas I had in mind was to have the last few gun cruisers (Des Moines, Newport News, Salem, Bremerton, Los Angeles and St. Paul) be refitted for providing the fire support duties in the early 1960s, including adding a plastic coating to their hulls for durability and corrosion prevention, and replacing the engines with effectively half the powerplants of the Kitty Hawk-class carriers, reducing maintenance complications and costs. In the early 70s, these are refitted with Sea Sparrow missile launchers and computerized engine controls, which along with other changes and improvements, which reduce the crew size from 1,150 (WWII) to about 700 by the early 1970s. Reagan's massive upbuild sees the two Alaskas rebuilt in the early 1980s, with them being designed as the Marines' "Cruiser Divisions" flagships. These were fitted with 6 Foster-Wheeler boilers and GE steam turbines, along with the computer-controlled boilers that became de rigeur on US steam-powered warships in the 1970s and 1980s, boosting their power to 210,000 shp. This massive additional power, however, was largely used to massively increase the ships' electrical generating capacity.
As of 1988, there are two of these, Cruiser Division One in the Atlantic, based at Norfolk (made up of Guam, Des Moines, Salem and Bremerton) and Cruiser Division Two in the Pacific, based in San Diego (made up of Alaska, Newport News, Los Angeles and St. Paul). The five Albany class cruisers (Oregon City and Rochester are also converted with Albany, Columbus and Chicago) are extensively refitted in 1979-81 to use the same engines as the gun cruisers, fitting them with the Mk-26 twin-rail missile launchers of the Ticonderoga and Kidd class vessels and outfitting them with Tomahawk cruise missiles, Harpoon anti-ship missiles and the Phalanx CIWS. In a smart piece of planning, among the developments for the AEGIS system was a system allowing the AEGIS-equipped vessels to transfer data to those without the AEGIS combat system but with the missile systems capable of intercepting air targets. All five of the cruisers are fitted with these electronics. Standard practice with the refitted Albany class ships was to pair one of them with an AEGIS cruiser, giving the ability to have two ships shooting at airborne targets.
