Why was Blackburn likely to receive the Skua and other naval aircraft work?
Short answerBlackburn had useful maritime experience and fit a policy of sustaining multiple aircraft firms; a Vickers sight link is plausible but unproven.
NotesBlackburn had several advantages when competing for naval aircraft work. Its aircraft had a reputation for coping with salt-water operations, which mattered directly to the Royal Navy. The Air Ministry also spread contracts among firms to preserve a broad aircraft design and production base for wartime mobilization. Coordination between Blackburn and Vickers over the Skua's dive-bomb sight remains an explicit, unproven suspicion.
