Bas 60 was primarily a response to the nuclear threat, so in the aftermath of the Six-Day War in 1967, and the introduction of long range attack aircraft, such as the Sukhoi Su-24, the system was further developed into Bas 90. Improvements in the Bas 90 system included construction of short backup runways in the direct vicinity of the airbases ...
Conceptual design of Project Habakkuk aircraft carrier with 600-metre (1,969 ft) runway. Project Habakkuk or Habbakuk (spelling varies) was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete, a mixture of wood pulp and ice, for use against German U-boats in the mid-Atlantic, which were beyond the flight range of land-based planes at that time.
Bas 90 (Flygbassystem 90, Air Base System 90) was an air base system used by the Swedish Air Force during the Cold War. Bas 90 was developed during the 1970s and 1980s from the existing Bas 60 system in response to the new threats and needs that had arisen since the conception of the Bas 60 system during the 1950s.
It went back to the US to finish its tests, but was badly damaged in a landing accident. In 1936 the aircraft was rebuilt with a 900 hp P&W "Twin Wasp" and redesignated the 28–90. After being purchased by British long-distance air racer James Mollison, he renamed the aircraft Dorothy after actress friend Dorothy Ward. Mollison used the ...
In London, pilot Beatty demonstrated a Wright aircraft retrofitted with a 50-hp Gyro engine. [8] The Gyro progressed to 80-hp in the seven-cylinder model by 1913, and up to 110 hp in the Model L nine cylinder "Duplex" with a unique cam-driven exhaust valve. The French Gnome Omega and future variants proved to be more popular in sales.
The base supported allied operations in region after landings in Normandy, as they headed east. By 1 March the Royal Canadian air force flying late model Spitfire fighter aircraft arrived at the base. Aircraft included versions of the Spitfire like the Spitfire FR Mk XIV, and other late model versions. There was various patrols, eventually the ...
In the late 1970s, Sweden sought to replace its aging Saab 35 Draken and Saab 37 Viggen. [7] The Swedish Air Force required an affordable Mach 2 aircraft with good short-field performance for a defensive dispersed basing plan in the event of invasion; the plan included 800 m long by 17 m wide rudimentary runways that were part of the Bas 90 system.
Bas 60 revolved around force dispersal of aircraft across many wartime air bases, including road runways acting as backup runways. [15] [16] [17] Utilizing partially destroyed runways was another factor that motivated STOL capability. Bas 60 was developed into Bas 90 in the 1970s and 1980s, and included short runways only 800 meters in length. [18]
