Aircraft Carriers: A History of Carrier Aviation and Its Influence on World Events: 1946-2006 v. 2 (Hardcover)
Author N Polmer
I would have put the demise of Aircraft Carriers as coincidental with the withdrawl of RN conventional fixed wing fleet circa '78ish, rather then the sixties, a mistake subsequently learned with a lack of UK AEW cover in the Falklands War.
The reluctance for the Argentinians to commit their carrier to sea has to be worth a few lines in your essay. Some would say this was an admission of it being a unprotected target linking submarine warfare to the demise of Carrier warfare. Fairly certain there is a torpedo with Gen Belgrano written on it somewhere.
