Information: - The Continuation War (25 June 1941 19 September 1944) consisted of hostilities between Finland and the Soviet Union from 1941 to 1944. The Continuation War began shortly after the end of the Winter War, which also was fought between Finland and the Soviet Union. In the Soviet Union, the war was considered part of the Great Patriotic War. Germany regarded its operations in the region as part of its overall war efforts on the Eastern Front, and it provided Finland with critical material support and military cooperation. - A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques, better materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s. - The Finnish Air Force (FAF or FiAF) (("Air Forces")) ("Air Arm"), is one of the branches of the Finnish Defence Forces. Its peacetime tasks are airspace surveillance, identification flights, and production of readiness formations for wartime conditions. As a separate branch of the military, the Finnish Air Force was founded on 4 May 1928, having existed officially since 6 March 1918 as the Army Corps of Aviation. - VL Kotka ( '' Eagle '' ) was a Finnish two - seat , biplane maritime patrol aircraft , designed and built by the Valtion lentokonetehdas or VL ( '' State Aircraft Factory '' ) . It was meant as a cheaper replacement ( compared to the Blackburn Ripon ) for the outdated IVL A.22 Hansas that were in service with the Finnish Air Force . The prototype made its first flight on September 30 , 1930 . In 1931 , the State Aircraft Factory began production of a series of five aircraft . These were used as liaison aircraft until 1944 . One aircraft ( KA - 147 ) is on display at the Paijat - Hame Aviation Museum . - The Blackburn T.5 Ripon was a British carrier-based torpedo bomber and reconnaissance biplane which first flew in 1926. It was used by the Fleet Air Arm as a torpedo bomber from 1930 until 1935. Ripons were also sold to Finland, where they continued to be used in action in the Winter War and the Continuation War until 1944. - A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous Second World War battles, notably the British attack at Taranto and the Japanese attack on Pearl Harbor. - The Winter War was a military conflict between the Soviet Union and Finland in 19391940. It began with the Soviet invasion of Finland on 30 November 1939 (three months after the outbreak of World War II), and ended with the Moscow Peace Treaty on 13 March 1940. The League of Nations deemed the attack illegal and expelled the Soviet Union from the League on 14 December 1939. - Finland , officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union. - In military operations, reconnaissance is the exploration outside an area occupied by friendly forces to gain information about natural features and enemy presence. - The Fleet Air Arm (FAA) is the branch of the British Royal Navy responsible for the operation of naval aircraft. The Fleet Air Arm currently operates the AgustaWestland Merlin, Westland Sea King, AgustaWestland Wildcat and Westland Lynx helicopters and the BAE Hawk. Helicopters such as the Lynx and Westland Wasp have been deployed on smaller vessels since 1964, taking over the roles once performed by biplanes such as the Fairey Swordfish. - The Finnish Defence Forces are responsible for the defence of Finland. A universal male conscription is in place, under which all men above 18 years of age serve for 165, 255 or 347 days. Alternative non-military service and volunteer service by women (about 500 volunteering annually) are possible.
