What impact could an earlier navalized Mosquito available in useful numbers have made?
Short answerIt would have been valuable for reconnaissance and long-range strike, including operations connected with the Indian Ocean crisis; the eventual naval development path led toward the Sea Hornet.
NotesAn earlier naval Mosquito would be well suited to reconnaissance and long-range attack. Earlier availability could help during the operational problems surrounding the Japanese Indian Ocean offensive. The later Sea Hornet embodied a related naval twin-engine concept. The counterfactual rests on having the aircraft in useful numbers soon enough to affect operations.
