How to build a deliberately incoherent 1960 fleet

If called in to update the fictional Elbonian Navy in 1960 as a traitorous procurement chief, what used ships would you buy or upgrade?

He would create an intentionally unbalanced fleet of rebuilt British carriers, Soviet ships, old US submarines, and mismatched British escorts.

The deliberately incoherent fleet combines rebuilt British armoured carriers, unreliable early Soviet vessels, worn American submarines, and a mixture of British escorts. Some individual choices, such as Battle-class destroyers, remain capable, but the total force lacks common equipment and a coherent operating concept. Flower-class corvettes sound useful for anti-submarine warfare yet would be too slow for the submarines of 1960. The joke works as a procurement lesson: buying famous or available ships is not the same as building a fleet whose parts can operate and sustain one another.
