Did the Fairey Swordfish originate in a Greek Navy requirement?
Short answerNo, not directly. Greek-linked earlier designs form part of the wider design lineage, but the Swordfish was not created from a Greek specification.
NotesDesign ancestry is different from the formal requirement that produced an aircraft. Earlier Fairey and Blackburn projects included machines modified or sold for Greek naval use, and some technical features can be traced through that family of work. The Swordfish itself did not originate in a Greek Navy specification, as far as the available knowledge in the answer goes. That leaves room for contrary evidence while making clear that a link between preceding export designs is not the same as the Swordfish's procurement origin.
