Austria had been a neutral country during the Cold War and so when the requirement for a new jet fighter arose in the early 1980s they bought used Drakens from Sweden, also a neutral country. After further upgrades including a self-defence system, the type entered service with the Austria air force in 1985 as J35Ö (for Österreich/Austria). Austria finally retired its Drakens in 2005. This example is now on display at the Arboga Robotmuseum, which mainly showcases the Swedish Armed Forces' robotic systems and engines (maintained in Arboga) from the late 1940s until the 2000s,
