ASW Reference: KM# 172 ELIZABETH II D·G·REGINA·, Portrait of Queen Elizabeth II facing right. CANADA 20 DOLLARS RRC, Lancaster 683 AVRO, John Emilius Fauquier in 24-karat plated gold cameo. The Avro Lancaster is a British Second World War heavy bomber.It was designed and manufactured by Avro as a contemporary of the Handley Page Halifax, both bombers having been developed to the same specification, as well as the Short Stirling, all three aircraft being four-engined heavy bombers adopted by the Royal Air Force (RAF) during the same wartime era. The Lancaster has its origins in the twin-engine Avro Manchester which had been developed during the late 1930s in response to the Air Ministry Specification P. 13/36 for a capable medium bomber for "world-wide use". Originally developed as an evolution of the Manchester (which had proved troublesome in service and was retired in 1942), the Lancaster was designed by Roy Chadwick and powered by four Rolls-Royce Merlins and in one version, Bristol Hercules engines. It first saw service with RAF Bomber Command in 1942 and as the strategic bombing offensive over Europe gathered momentum, it was the main aircraft for the night-time bombing campaigns that followed. As increasing numbers of the type were produced, it became the principal heavy bomber used by the RAF, the Royal Canadian Air Force (RCAF) and squadrons from other Commonwealth and European countries serving within the RAF, overshadowing the Halifax and Stirling. 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).
Loads often supplemented with smaller bombs or incendiaries. The "Lanc", as it was known colloquially, became one of the most heavily used of the Second World War night bombers, "delivering 608,612 long tons of bombs in 156,000 sorties". 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 German Ruhr valley dams.Although the Lancaster was primarily a night bomber, it excelled in many other roles, including daylight precision bombing, for which 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). This was the largest payload of any bomber in the war. In 1943, a Lancaster was converted to become an engine test bed for the Metropolitan-Vickers F. Lancasters were later used to test other engines, including the Armstrong Siddeley Mamba and Rolls-Royce Dart turboprops and the Avro Canada Orenda and STAL Dovern turbojets. Postwar, the Lancaster was supplanted as the main strategic bomber of the RAF by the Avro Lincoln, a larger version of the Lancaster.
The Lancaster took on the role of long range anti-submarine patrol aircraft (later supplanted by the Avro Shackleton) and air-sea rescue. In March 1946, a Lancastrian of BSAA flew the first scheduled flight from the new London Heathrow Airport. The land now called Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the late 15th century, British and French colonies were established on the region's Atlantic coast. As a consequence of various conflicts, the United Kingdom gained and lost North American territories until left, in the late 18th century, with what mostly comprises Canada today.
Pursuant to the British North America Act, on July 1, 1867, three colonies joined to form the autonomous federal Dominion of Canada. This began an accretion of provinces and territories to the new self-governing Dominion. In 1931, Britain granted Canada near total independence with the Statute of Westminster 1931 and full sovereignty was attained when the Canada Act 1982 severed the vestiges of legal dependence on the British parliament. Canada is a federal parliamentary democracy and a constitutional monarchy, Queen Elizabeth II being the current head of state.The country is officially bilingual at the federal level. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries, with a population of approximately 35 million as of 2015. Its advanced economy is the eleventh largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks.
Canada's long and complex relationship with the United States has had a significant impact on its economy and culture. Canada is a developed country and one of the wealthiest in the world, with the tenth highest nominal per capita income globally, and the eighth highest ranking in the Human Development Index. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, and education.
Canada is a Commonwealth Realm member of the Commonwealth of Nations, a member of the Francophonie, and part of several major international and intergovernmental institutions or groupings including the North Atlantic Treaty Organization, the G8, the Group of Ten, the G20, the North American Free Trade Agreement and the Asia-Pacific Economic Cooperation forum.
