A Hawkeye answer to carrier early warning

What would most likely replace the Fairey Gannet in AEW and carrier-onboard-delivery roles if the Royal Navy had kept CVA-01 carriers?

The E-2 Hawkeye is the likeliest AEW choice, with C-2 Greyhounds for COD, while Gannets remain on older carriers and the Type 768 probably goes no further.

The E-2 Hawkeye is the favoured replacement for the Fairey Gannet in airborne early-warning service if the Royal Navy retained CVA-01 carriers. That choice follows the British purchase of Phantoms and would leave more British funding for the Buccaneer and Sea King programmes. A C-2 Greyhound could cover carrier-onboard delivery without requiring Britain to finance another aircraft line. The CVA-01 catapult would have needed work for heavier aircraft, while the older Audacious carriers would likely have kept Gannets until retirement. The proposed Hawker Siddeley Type 768 was another possibility, although the assessment doubts that it would have been pursued far enough to displace the American option.
