The three-seat Fairey Seal points toward the Swordfish

The Fairey Seal carried three crew members for the combined demands of flying, observing, communicating, and self-defence. Its pilot, observer, and telegraphist or gunner arrangement supported spotting and reconnaissance without surrendering the ability to coordinate with the fleet. Fairey's emphasis on these roles contrasted with Blackburn's established position in torpedo bombers. The Seal was a conceptual and crew-layout forerunner of the Swordfish, where Fairey's reconnaissance lineage would merge with torpedo attack.
