An Am Lancaster I carrying standard British night-bomber camouflage. Note how far up the side of the fuselage the matte-black underside pigment extends. Blazon B roundels are on top of the wing; Blazon C. 1 roundels are on the fuselage. The fin flash is 24x36 inches.

HE Avro Lancaster was the most famous and widely used four-engine British bomber of WW Ii. Oddly, however, it didn't originate as a four-engine design. In 1937, the British Air Ministry issued a requirement for a heavy bomber to be powered with ii new and still experimental i,760hp Rolls-Royce Vulture engines.

A.5. Roe and Co., Ltd., of Newton Heath, Manchester, won the order with its Model 679—named "Manchester" by the Purple Air Forcefulness. The prototype was start flown in July 1939. The program was seriously delayed by a German language air raid, and it was then ended by the shortcomings of the still-troublesome Vulture engine (priorities for the Merlin engine prevented Rolls-Royce from perfecting the Vulture). Only 200 Manchesters were built, some of which saw action over Germany (February 1941 to June 1942).

To save the Manchester program, Avro developed a four-engine modification of the basic airframe. It had a wider middle department and longer fly panels for use with the 1,145hp Rolls-Royce Merlin engine (every bit used in the Bell-ringer Hurricane and Supermarine Spitfire fighter). These changes increased the wingspan from 90 feet, 1 inch to 102 feet for the same 50,000-pound gross weight. The converted airframe, originally named "Manchester III," beginning flew on January 9,1941. The Air Ministry was pleased with its operation and immediately ordered the revised blueprint into product designated every bit the "Avro Model 683 Lancaster."

Demand was more than Avro could handle, and then production of an eventual 7,374 Lancasters was distributed among two Avro plants and one Canadian and four other British manufacturers. The first production Lancaster I, powered by ane,260hp Merlin Twenty engines, flew on October 31,1941. The brusk fourth dimension information technology took to move the Lancaster from image to production can be attributed to its being essentially a modified Manchester, not a completely new design.

Both offensively and defensively, the Lancaster I was a formidable machine, with a gross weight of 65,000 pounds—greater than that of the American Boeing B-17. It could normally carry 7,000 pounds of bombs and was dedicated by four powered motorcar-gun turrets with 10 to 12,303-caliber guns. Lancasters first went into activeness in March 1942 and were the backbone of the British heavy bomber armada for the rest of the state of war.

As a precaution against a shortage of Merlin engines, a Lancaster II using the 1,650hp Bristol Hercules VI air-cooled radial engine was developed. A big production order was placed with one of the subcontractors, but the anticipated Merlin shortage didn't materialize, so the Lancaster II order was progressively reduced until only 300 were delivered. Lancasters that had Merlin engines built in the U.S. by Packard were designated "Lancaster III" (2,990 produced). The 430 congenital in Canada with Packard Merlins were identified as "Lancaster X."

Intermediate marks identified various improved ver sions: Marks Iv and V were special long-range versions; Marking VI had improved 1,750hp Merlins; and Mark VII had i,620hp Merlins but a gross weight of 68,000 pounds. Marks Eight and IX

weren't used.

The Lancasters were used primarily equally night bombers in the Centrolineal program that bombed Frg "around the clock"—the Americans attacking past day, the British past dark. Specially modified Lancasters were used on some spectacular missions, such every bit the breaching of the Mohne and Eder dams in May 1943 and the sinking of the battleship Tirpitz, subconscious in a Norwegian fjord, with a unmarried 12,000-pound bomb in Nov 1944. Special Lancasters modified to conduct 22,000-pound Thousand Slam bombs had gross weights of 72,000 pounds.

Lancasters remained in service with the Royal Air Force until Feb 1954 and with the Purple Canadian Air Force until April 1964. Only two fly-able Lancasters remain today.
