The Norman Thompson N.T.2B combined lessons learned from the White and Thompson No.3 Flying Boat and F.B.A. flying boats, which had been built under contract. It was intended primarily as a trainer and had dual controls fitted. A variety of engines were mounted, starting with the 160hp Beardmore and proceeding to the 150hp Hispano-Suiza and ultimately the 200hp Hispano-Suiza. The Sunbeam Arab was tried but that engine proved troublesome.

Even at the end of the war there were seventy-nine on charge, with twenty three on active duty at coastal stations. [1]

Production of N.T.2b's never kept up with orders, and engine troubles also contributed to short deliveries. After the war, the firm was bought by Handley-Page, who had little success trying to open the market for light flying boats after the war.[3]
