Did naval projects ever receive money indirectly through other contracts?
Short answerProbably; Vickers aviation equipment suggests Admiralty funding may have supported undeclared work alongside legitimate ship-related contracts.
NotesThe Skua's dive-bombing sight appears in the record with surprisingly little visible development funding. Similar mysteries surround engines and other Fleet Air Arm equipment available as war begins. Legitimate Admiralty payments to Vickers for naval work could also have financed related aviation projects. Sudden wartime availability is therefore a clue to research hidden inside another contract rather than proof that a system appeared from nowhere.
