The RN originally intended to have Blackburn build Albacores. But the contract was switched to Swordfish because the jigs were becoming available from Fairey and less need for strategic materials. That enabled the aircraft to be available sooner which in 1939 was what the RN needed. In late 1939 Barracuda production wasn't scheduled to begin until April 1941 in succession to Fulmar production at Fairey Stockport.
