British aircraft aboard American carriers

What could the US Navy have learned from receiving British Sea Vixens, Scimitars, and Phantoms in the 1950s?

Both navies could examine useful aircraft and engine choices, while British pilots would also experience the advantages of larger American carriers.

Operating Sea Vixen, Scimitar, or British Phantom variants from Saratoga and Independence would allow both navies to examine useful design choices. The British Phantom was adapted to British operating requirements, and its Rolls-Royce engines attracted American interest, although their extra weight offset some advantages. The United States already had good aircraft of its own, so the value would be in mutual comparison. British pilots might also prefer the larger American carriers, raising the question of funding comparable ships.
