The Brits let their AEW and long-range intercept capability atrophy because MoD had assumed for years that any future war Britain fought would be a NATO war; thus, they would have Hawkeyes and Tomcats for that sort of thing. The RN point-defense weapons like Sea Cat were proved seriously deficent against cruise missiles and even Scooters with iron bombs, especially when crippled by lack of effective AEW. Fortunately, the Argies didn't have many Exocets to play with, and after the General Belgrano was torpedoed, the Argie Navy sat out the rest of the war. Read Admiral Woodward's book, it's very pertinent to our Navy's future vs. well-trained peer competitors.
As for why the C-2B will be able to tank? It's because the Rhino guys heard about this and started screaming and twitching.
