Sweden is not a large country and Saab was not a large company compared to many of its contemporaries this meant that whatever else the company incorporated into the design, development and export potential had to be in the mix. Of course, military considerations were not the only driving force in the Draken’s design. The Draken would be a component of the “STRIL 60” network which was activated in 1960 and remained in service through to the early 1990s. Known as “STRIL” for short, the network was composed of early warning radars and ground control centres which controlled and guided aircraft to their targets. Also essential was that the aircraft spend a minimum amount of time on the ground between missions, the Draken had to be refueled and rearmed and put back into action in less than ten minutes.įrom a strictly Swedish standpoint, the aircraft had to be compatible with the country’s Stridsledning integrated air combat management network. The Draken would also need to be easily and competently maintainable by a small number of conscripted ground crew with possibly minimal training, so robust and relatively simple systems which could be easily accessed were a must.

Through the Cold War, Sweden became well known for requiring their combat aircraft to be able to use straight stretches of highway as improvised runways and for the aircraft to be fully supportable away from a fully equipped permanent base. As such, Sweden had rather different expectations of a combat aircraft than some other nations did. As a neutral country, Sweden shaped its defense network independent of other nations’ philosophies. This fact was but one contributing factor to the Draken’s groundbreaking design.Īnother key aspect that dictated the Draken’s design was Sweden’s own unique defensive doctrine. When the bombers became faster and flew higher, it was clear that the firmly subsonic J-29 and J-32 fighters were not up to the task of effectively intercepting them, supersonic speeds were essential. However, both designs were thoroughly conventional and mirrored aircraft design philosophies of their day.īy contrast, the J-35 Draken was a fully new design which showed that Saab could more than match what their contemporaries were producing and were not at all afraid to innovate.įormer Austrian air force J-35OE Drakens preserved at Zeltweg, Austria in 2022.Īt the height of the Cold War, incursions into domestic airspace by Soviet bomber aircraft were as much a concern to Sweden as they were to other western countries in the northern hemisphere. The J-29 and J-32 were well regarded in the aviation world and stood as testament that Saab were capable of designing jet fighter aircraft which could match the capabilities of designs produced by larger, better known names in aviation. The company’s first jet fighter designed as such from the ground up, the J-29 Tunnan, entered Swedish air force service in 1950 and was followed in 1956 by the J-32 Lansen. Before the 1940s were finished, the company had developed the J-21R jet fighter from its J-21 piston powered fighter. Saab was not unknown in jet fighter development prior to the J-35 Draken. Not only was the overall design a modern and unexpected departure from aircraft design norms of the period, the source of the aircraft was also something of a shock that a relatively small company on the aviation landscape from a politically neutral nation would present the world with an all weather fighter capable of speeds exeding twice the speed of sound was unexpected indeed. When Saab’s J-35 Draken (Dragon) entered Swedish air force service in 1960 after a rigorous design and development period, it caused a stir in the aviation world at large.
