Swedish Air Force

The Swedish Air Force (Svenska flygvapnet or just Flygvapnet) is the air force branch of the Swedish Armed Forces. The Swedish Air Force was created on 1 July 1926 when the aircraft units of the Army and Navy were merged. Because of the escalating international tension during the 1930s the Air Force was reorganized and expanded from four to seven squadrons. When World War II broke out in 1939 further expansion was initiated and this substantial expansion was not finished until the end of the war. Although Sweden never entered the war, a large air force was considered necessary to ward off the threat of invasion and to resist pressure through military threats from the great powers. By 1945 the Swedish Air Force had over 800 combat-ready aircraft, including 15 fighter divisions. A major problem for the Swedish Air Force during World War II was the lack of fuel. Sweden was surrounded by countries at war and could not rely on imported oil. Instead domestic oil shales were heated to produce the needed petrol. About 250 aircrew were killed in crashes 1939-1945 according to statistics that were not disclosed during the war years but published afterwards. The Swedish Air Force underwent a rapid modernization from 1945. It was no longer politically acceptable to equip it with second-rate models. Instead, the Air Staff purchased the best it could find from abroad, e.g. P-51D Mustangs, De Havilland Mosquito NF.19 night fighters and de Havilland Vampires, and supported the development of top performance domestic models. The Saab 29 Tunnan jet fighter was introduced around 1950. In the late 1950s the Swedish Air Force introduced the Bas 60 air base system, which revolved around force dispersal of air squadrons across many wartime air bases in case of war in order to make it complicated for an opponent to destroy the air force on the ground. Road runways were also introduced as backup runways. Bas 60 was developed further into Bas 90 during the 1970s and 1980s.
