So, what if the Soviet naval threat escalated out of hand in the 50s. Things remained stable unil the 80s, when Reagan announced the 600 ship navy. The USSR responded with a 600 ship fleet of its own, which prompted modernization programs in addition to new construction.
USS Hancock CVT-19Upgraded with the Antietam CV-36 in the early 80s as all around training and qualification carriers. The sponsons will receive CIWS and SeaSparrow launchers, for weapons quals.

USS South Dakota BB-57My second attempt to modernize a Hasegawa SD class.
USS Kentucky BBH-5 USS Washington, USS indiana, and USS Kentucky were converted into BBHs in the early 60s in response to the USSRs Moskva class of helo cruisers. I also have started a model of BBH-2 USS Washington.
USS Baltimore CA-68 and USS Portland CG-15:CA rebuild program targeted the Baltimore class CAs that weren't upgraded previously to CGs. Conversions on the 10 ships took place ca 1968 to 1973.
CG-15 reflects an upgrade to the Portland/Northampton class in the early 50s, and modernized in 1982-1983.
Not yet ready to show off is my USS Princeton, LPH-5. The 3 Essex LPH conversions were also deemed important in 72 and underwent an extensive overhaul in 76-77. Too many spare parts I guess I apologize for any inaccuries, I went to the Navy recruiter 12 years ago, but he couldn't guarentee I could get on a ship. Out of spite, I walked across the hall and enlisted in the USAF.
