I always had the impression the Mosquito replaced the Beaufighter in alot of roles; Nightfighting for example...- While I have the utmost respect for the Beau and all it's Duties-performed, the Mosquito was capable of heavier armament...37 AND 57mm cannon, and the humble .303 was more than a flea in the ear, in a dogfight or ground-attack -[50 cal. would've been better, however...] - the American Mossies were mostly Reconnaissance variants although Canada sent them some Bomber ones too. - Although the Beau was heavier, they shared the 4 cannon and 60lb rocketry, .303's, torpedos, mines etc. but the speed manoevrability, range, altitude and bombing recce roles were Mosquito advantages...bloody shame they didn't have the DH.-103 Hornet up going , because they went FAA postwar too...
