The Swordfish story begins with Admiralty and Air Ministry discussions in 1928, before the later formal requirement. Specifications appeared in 1930 for two related aircraft with similar performance but different maritime roles. Those lines later merged and accelerated into the program commonly recognized in the early 1930s. Renaming or combining requirements can make a continuous development effort look like a new project. The example shows why procurement history must be traced through conversations, specifications, and inherited work rather than the latest label on the file.
