History and background

Studies concerning a replacement for the Swedish Air Force system, Viggen, were conducted throughout the 1970's. The vision of a single aircraft for hunting, attack and reconnaissance missions has a long presence in the Swedish Air Force. Ideas for multi-role aircraft were included in future plans already in the mid-1970's.

Swedish industry's most advanced development project so far

At the design stage, FMV had to find the optimal combination of properties that met the requirements. Key elements proved to be variable nose wing in combination with an electronic control system. It meets not only today's requirements, but also increases the possibilities for future unconventional solutions.

The JAS 39 Gripen is the most advanced development project so far in Swedish industry. Throughout the 1980's, between 2,000 and 3,500 people were engaged in the development work, which took a total of more than 30,000 person-years.

Much of the work involved the development and application of new technology in many fields, such as:

  • New electronic components and circuits, including radar and presentation equipment.
  • New types of electronic signal transmission in aircraft.
  • Comprehensive integrated computer systems.

A single contracting party of five industrial companies

After the Swedish parliamentary decision in 1982, FMV signed agreements for the development of the JAS 39 Gripen. The contract included five test airplanes and a first batch of 30 airplanes and associated support systems.

There was also an option for another 110 airplanes. The provider was the Industrial Group JAS, IG JAS, a single contracting party of five industrial companies.

Continued development

Ten years later, FMV agreed with the IG JAS on the conditions for continued development and manufacturing. The agreement included, among other things:

  • Development of the two-seater version JAS 39B.
  • Acquisition of a second batch of 110 airplanes including 14 two-seaters.
  • Acquisition of additional support systems.

The Swedish Government decided in 1997 on the acquisition of a third batch including 64 airplanes and further development- and adaptation programs. Delivery to the Swedish Armed Forces began in 2003, and in December 2008 the final aircraft in the third batch was delivered.
