Specification C.26 /31 required a dual-purpose bomber /transport aircraft for service with the Royal Air Force (RAF), with the specification stressing the transport part of its role. The AW.23 was designed by John Lloyd, chief designer of Armstrong Whitworth to meet this specification, competing with the Handley Page HP.51 and the Bristol Bombay. The AW.23 was a low-wing twin-engine monoplane, powered by two Armstrong Siddeley Tiger engines. It had a fabric covered braced steel fuselage accommodating a large cabin to fulfill its primary transport role, but with room for internal bomb racks under the cabin floor. The aircraft's wings used a novel structure, patented by Armstrong Whitworth, which used a massive light alloy box-sparbraced internally with steel tubes. This structure was extremely strong but required a thick wing section, increasing drag. This wing structure was re-used in Armstrong Whitworth's Whitley bomber. The AW.23 was the first Armstrong Whitworth Aircraft to be fitted with a retractable undercarriage. A single prototype, K3585, was built first flying on 4 June 1935. Owing to its unreliable Tiger engines, its delivery to the RAF for testing was delayed, with the Bombay being declared the winner of the specification.
The prototype was given the civil registration G-AFRX in May 1939 being used for inflight refuelling development by Flight Refuelling Ltd who used it with the Short Empire flying boat. It was used in February 1940 for the world's first night refuelling experiments. It was destroyed in a German bombing raid on Ford airfield in June 1940.

Designed as a military transport, similar to the Bristol Bombay. Although it was never produced in quantity, it formed the basis for the design of the Whitley bomber.

has a look of a plane more of the earlie 40's maybe with better engines it would have done better

You can see where the Whitley came from.

Looks a bit like a Fiat BR20 Cicogna
