Avro Lancaster Aircraft Overview

British heavy bombers from the Second World War included the Avro Lancaster. It was created and produced by Avro as a contemporaneous to the Handley Page Halifax and the Short Stirling, both four-engined heavy bombers used by the Royal Air Force (RAF) during the same period of World War II and developed to the same specifications.

The twin-engine Avro Manchester, which was created in the late 1930s in answer to the Air Ministry Specification P.13/36 for a medium bomber for “worldwide usage” that could carry a torpedo internally and conduct shallow dive-bombing operations, is where the Lancaster had its start. The Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlin and, in one form, Bristol Hercules engines. The Lancaster was first conceived as an upgrade of the Manchester (which had proven problematic in service and was decommissioned in 1942). It was originally used by the RAF Bomber Command in 1942, and when the strategic bombing campaign over Europe gained steam, it served as the primary aircraft for the next nighttime bombing operations.

The Avro Lancaster was modified in 1943 to serve as a Metropolitan-Vickers F.2 turbojet engine test bed. Later, various engines, such as the Avro Canada Orenda and STAL Dovern turbojets and the Armstrong Siddeley Mamba and Rolls-Royce Dart turboprops, were tested using Lancasters. After the war, the Avro Lincoln, a bigger version of the Lancaster, replaced the Lancaster as the primary strategic bomber of the RAF.
