If Barracuda had served for more than a year before the Royal Navy obtained Avengers, would it avoid replacement?
Short answerPossibly; a timely and established Barracuda program could remove much of the pressure that led the Fleet Air Arm to acquire Avengers.
NotesThe scenario changes the reason for buying the American aircraft. The Royal Navy might not obtain Avengers at all if Barracuda were already established because Barracuda delays helped create the requirement. Procurement responds to program timing and available capacity as well as the relative merits of two aircraft.
