The Royal Air Force launches 29 Avro Lancaster bombers in one of the most successful precision bombing attacks of war and sinks the German battleship Tirpitz
, with 12,000 lb Tallboy bombs off Tromsø, Norway. Tirpitz was the second of two Bismarck-class battleships built for the German Kriegsmarine during World War II. Named after Grand Admiral Alfred von Tirpitz, the architect of the Imperial Navy, the ship was laid down at the Kriegsmarinewerft in Wilhelmshaven in November 1936 and launched two and a half years later in April 1939. Work was completed in February 1941, when she was commissioned into the German fleet.

The Avro Lancaster is a British four-engined Second World War heavy bomber made initially by Avro for the Royal Air Force (RAF). It first saw active service in 1942, and together with the Handley Page Halifax it was one of the main heavy bombers of the RAF, the RCAF, and squadrons from other Commonwealth and European countries serving within RAF Bomber Command. The "Lanc", as it was affectionately known, became the most famous and most successful of the Second World War night bombers, "delivering 608,612 tons of bombs in 156,000 sorties." Although the Lancaster was primarily a night bomber, it excelled in many other roles including daylight precision bombing, and gained worldwide renown as the "Dam Buster" used in the 1943 Operation Chastise raids on Germany's Ruhr Valley dams.
