How many British organizations were involved in developing naval guns?
Short answerSeveral: Vickers-Armstrong participated alongside other private firms, naval organizations, and nationally owned gun foundries.
NotesVickers-Armstrong was one participant in British naval-gun development. Other firms, naval organizations, and state gun foundries also contributed. This distributed industrial base gave the Admiralty several possible producers and sources of technical work. Funding and orders across that network were the relevant constraints because Britain did not lack domestic gun-making capacity.
