Handley Page O/400 (H.P.12)

The four- to five-seater heavy bomber biplane of unequal wingspan, powered by two engines, was created as a successor to the Handley Page O/100 bomber and its dimensions almost reached the size of a twenty-year younger, later so successful Boeing B-17 Flying Fortres bomber. After finding out that it is possible to perform "accurate" bombing at night, in August 1917 an order was placed for prototypes of new night bombers and signed a contract for the supply of improved aircraft O/100, now known as O/400, which were to respond to German air raids. to Britain and counterbalance the German bombers Gotha and Zeppelin.
