Victory Aircraft - Avro Lancaster X

Avro Lancaster X

A Lancaster Mk I (R5727) from Avro Aircraft (UK) was flown across the Atlantic in August 1942, to act as a "pattern" aircraft for production. Differences between the British Lancasters and the Canadian built versions (known as the Mk X) revolved around engines, instruments and radio equipment being manufactured in Canada or the United States instead of England. The Rolls-Royce Merlin engines were the same design, but manufactured by Packard in the United States. A later series Lancaster Mk X replaced the original Frazer-Nash FN 50 mid-upper turret with a US-made Martin 250CE turret moved to a new location farther back on the upper fuselage due to differences in weight between that unit and the original turret. All major sub-assemblies of the Canadian Lancasters were interchangeable with the British versions so that in the event of damage, spare parts were immediately at hand.

Initially, all components were built at Malton except for the bomb doors, flaps, ailerons and elevators, that were produced by Ottawa Car & Aircraft Ltd. Later, more of the parts were subcontracted out with Canadian General Electric Co. Ltd. of Toronto constructing the fuel tanks, tailplane, fins and rudders, while the outer wings were subcontracted to the Fleet Aircraft Limited plant in Fort Erie, Ontario.

From the first blueprints arriving to the first test flight took only 16 months, an impressive accomplishment, not lost on Avro (UK) management. The Malton work force climbed from 3,300 (1942) to 9,521 in 1944, most of them initially unskilled workers and about a quarter of them women. Almost exactly a year to the day from when the "pattern" aircraft was flown to Canada, the Canadian prototype, (serial number KB700), rolled off the Victory Aircraft assembly line on 1 August 1943. Named the "Ruhr Express," much publicity was made of its christening, first flight and its departure (albeit delayed as the prototype was wheeled out missing some of its essential gear and was barely able to fly) to England. Nevertheless, the Avro Lancaster setting off for war was an occasion for which the country could be proud.

Eventually, Lancaster production at Victory Aircraft Ltd. reached the impressive mark of one aircraft per day. After being ferried to England and sent to operational squadrons, the Canadian "Lancs" were assigned to No. 6 Group RAF, the RCAF component of RAF Bomber Command, to complete this "all-Canadian" contribution to the war effort. The Malton plant went on to build by war's end, a total of 3,629 Avro aircraft: 3,197 Ansons, 430 Mk X Lancasters (including six Lancastrian transport conversions), one Mk XV Lincoln heavy bomber, and a single York transport.
