https://en.wikipedia.org/wiki/Avro_Lancaster
The Avro Lancaster is a British four-engined Second World War heavy bomber
designed and built by Avro for the Royal Air Force (RAF). It first saw active
service with RAF Bomber Command in 1942 and, as the strategic bombing offensive
over Europe gathered momentum, it was the central implement for the night-time
bombing campaigns that followed. It became the main heavy bomber used by the
RAF, the RCAF, and squadrons from other Commonwealth and European countries
serving within the RAF, overshadowing its close contemporaries the Handley Page
Halifax and Short Stirling. The "Lanc", as it was affectionately known, thus
became one of the more famous and most successful of the Second World War night
bombers, "delivering 608,612 long tons of bombs in 156,000 sorties." The
Lancaster, an evolution of the troublesome Avro Manchester, was designed by Roy
Chadwick and was powered by four Rolls-Royce Merlins, or, in one version,
Bristol Hercules engines.
A long, unobstructed bomb bay meant that the Lancaster could take the largest
bombs used by the RAF, including the 4,000 lb (1,800 kg), 8,000 lb (3,600 kg),
and 12,000 lb (5,400 kg) blockbusters, loads often supplemented with smaller
bombs or incendiaries. The versatility of the Lancaster was such that it was
chosen to equip 617 Squadron and was modified to carry the Upkeep "Bouncing
bomb" designed by Barnes Wallis for Operation Chastise, the attack on Germany
Ruhr Valley dams. Although the Lancaster was primarily a night bomber, it
excelled in many other roles, including daylight precision bombing: in the
latter role some Lancasters were adapted to carry the 12,000 lb (5,400 kg)
Tallboy and then the 22,000 lb (10,000 kg) Grand Slam earthquake bombs (also
designed by Wallis).

The first RAF squadron to convert to the Lancaster was No. 44 Squadron RAF in
early 1942.
Lancasters flew 156,000 sorties and dropped 608,612 long tons (618,378 tonnes)
of bombs between 1942 and 1945. Lancasters were the mainstay of British heavy
bombers from 1942 until the introduction of the Lincoln in large numbers,
post-Second World War. Just 35 Lancasters completed more than 100 successful
operations each, and 3,249 were lost in action. The most successful survivor
completed 139 operations, and was scrapped in 1947.
