The first true production Lancaster bomber flew in October 1941 (Avro Lancaster I).
Equipped with four Rolls-Royce Merlin XX developing 1,280 hp each, the maximum take-off weight of the Lancaster I was 60,200 pounds (data from trials that took place during April and May of 1942. Later, the all-up weight of the aircraft was set at 65,000 lbs.) The maximum bombload was 12,000 pounds, (later 18,000 pounds) giving it an operational radius of 550 miles. With 4,000 pounds of bombs, it could reach targets 875 miles away.
Compared with the B-17 it could fly almost as fast (275mph vs 282 mph), although it operated at much lower altitudes (ceiling of 19,000 feet versus 36,950 for the B-17G, although during combat conditions both bombers operated at altitudes somewhat lower than their service ceilings). It carried less armor, and less defensive armament, but a much heavier bombload. Even though the maximum take-off weight was almost identical (67,860 lbs. of the B-17G), the typical Lancaster bombload was 12,000 lbs. vs 5,000 of the B-17 (for the same distance, the Lancaster could carry a heavier bombload).
Although it was designed as a high-altitude night-bomber, one of its first missions was carried out in daylight (more precisely at dusk so the bombers would benefit from darkness on the homeward run) at tree-top altitude. On 17 April 1942, 12 Lancasters, six each from 44 and 97 Squadrons bombed the M.A.N. factory at Augsburg. Four were shot down by JG 2 near the coast and three more by Flak near the target. The bombing was precise but the effect on the German production of diesel engines for submarines was not very significant.
The Lancaster would become the mainstay of British Bomber Command and would later find much success in operations.
