Possessing an all-metal structure with fabric covering and all four guns located in the fuselage, the A.10 suffered handling and performance shortcomings which led to numerous modifications, including fuselage lengthening. Under the military serial L1949 it was assessed at the A&AEE against other F.20/27 contenders and also for F.10/27 (which called for six-gun armament), but it aroused little enthusiasm and was struck off Air Ministry charge in November 1933 – by which time its manufacturer had become Saunders-Roe Limited.
