It was developed by Handley Page to the same specification as the contemporary twin-engine Avro Manchester. The Halifax has its origins in the twin-engine HP56 proposal of the late 1930s, produced in response to the British Air Ministry's Specification P.13\/36 for a capable medium bomber for \"world-wide use.\" The HP56 was ordered as a backup to the Avro 679, both aircraft being designed to use the underperforming Rolls-Royce Vulture engine. The Handley Page design was altered at the Ministry to a four-engine arrangement powered by the Rolls-Royce Merlin engine; the rival Avro 679 was produced as the twin-engine Avro Manchester which, while regarded as unsuccessful mainly due to the Vulture engine, was a direct predecessor of the famed Avro Lancaster. Both the Lancaster and the Halifax emerged as capable four-engined strategic bombers, thousands of which were built and operated by the RAF and several other services during the War. \u003c\/p\u003e","brand":"Ian Allan","offers":[{"title":"Default Title","offer_id":67670938747179,"sku":"17967","price":32.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1022\/1289\/5019\/files\/halifax-special-bruce-robertson-1990-1st-edition-hardback_17967_main_original.jpg?v=1791254298","url":"https:\/\/militaryhistorybooks.com\/products\/halifax-special-bruce-robertson-1990-1st-edition-hardback","provider":"Military History Books","version":"1.0","type":"link"}
