The squadron was reformed at RAF Calshot on 1 January 1929. In April 1936 their Southamptons gave way to the Saro London, which the squadron still had on strength when World War Two broke out. Supermarine Stranraers were with the squadron in 1939, but by April 1940 they were operating the Short Sunderland, which would remain with the squadron for almost seventeen years up to 28 February 1957, when the squadron was disbanded at RAF Pembroke Dock.
