  • Avro Manchester Heavy Bomber Aircraft

    The development of the Avro Manchester led directly to the development of the outstanding Avro Lancaster.

     Updated: 5/17/2017; Authored By Staff Writer; Content ¬©www.MilitaryFactory.com

    The Avro Manchester was a semi-successful attempt by the Avro firm to fulfill Air Ministry Specification P.13/36. The specification called for a twin engine heavy bomber that could sport a multi-purpose payload of bombs or torpedoes. Unlike the Handley Page Halifax four engine offering - a bomber designed to the same Air Ministry Specification - the Manchester would see a shortened production run, short term service life and operational service rife with engine troubles. In the end, only 209 Manchesters would ever be completed, with production split between Avro (177) and Metropolitan-Vickers (32).

    Outwardly, the Manchester was similar to other multi-engine Avro offerings during the Second World War (Lincoln, Shackleton, Lancaster). The twin engines were underslung on mid-mounted monoplane wings with dihedral outboard of the engines and main wheel undercarriage. The fuselage was of a mostly straight yet slender design from nose to tail. The flight deck maintained a good all-around vantage point and featured extensive framing. The empennage was dominated by the identifiable twin vertical fin arrangement common to other Avro designs. The initial production Manchester, however, sported a third vertical tail fin running between the base two and along the rear portion of the upper fuselage. The rear fuselage extended out beyond this assembly, which held the rear gunner's position.
