The Handley Page H.P.43 was a three-engined biplane bomber-transport built to an Air Ministry specification. It did not fly well and the biplane configuration was out-dated at completion; the only one constructed was later turned into a monoplane and led to the Handley Page H.P.54 Harrow.

The Handley Page H.P.54 Harrow was a heavy bomber designed and produced by the British aircraft manufacturer Handley Page. It was operated by the Royal Air Force (RAF) and used during the Second World War, although not as a bomber.
