How would the early war change if the Swordfish had been a monoplane?
Short answerBritain might skip the Albacore and adopt monoplane carrier fighters earlier, but the result would be a fundamentally different aircraft and development path.
NotesChanging the airframe changes much more than appearance: cockpit, range, endurance, and the surrounding generation of Fleet Air Arm aircraft all move with it. A monoplane Swordfish could encourage an enclosed cockpit and make monoplane carrier fighters appear earlier. It might also remove the need for the Albacore as an interim replacement. The historical Swordfish was only three years into service in 1939 and was technically capable for the specification it had been given.
