Lla Saab JAS 39 Gripen (Anglais: « Griffin ») est un avion de chasse multirôle monomoteur léger fabriqué par la société aérospatiale suédoise Saab. Il a été conçu pour remplacer le Saab 35 Draken et le 37 Viggen dans l’armée de l’air suédoise (Flygvapnet). Le Gripen a une aile delta et une configuration canard avec une conception de stabilité détendue et des commandes de vol fly-by-wire. Il est alimenté par la Volvo RM12, et a une vitesse de pointe de Mach 2. Les aéronefs ultérieurs sont modifiés pour les normes d’interopérabilité de l’OTAN et pour effectuer le ravitaillement en vol.

Lla « JAS » Philosophy
Lla Saab JAS 39C Gripen is a lightweight, single-engine multirole fighter designed to replace the Draken and Viggen. The acronym JAS stands for Jakt (Air-to-Air), Attaquer (Air-to-Surface), and Spaning (Reconnaissance). Unlike larger, more expensive fighters, the Gripen was built for « Total Defense »—the ability to be maintained by conscripts and operated from ordinary highways in the Swedish countryside during a conflict. It is widely considered one of the most cost-effective 4.5-generation fighters in existence.

Smart Design for Austere Conditions
- Road Base Operations: The Gripen is specifically designed to land on a 800-meter stretch of highway. Its canards can be tilted forward after landing to act as massive air brakes, pushing the nose down and allowing for heavy braking without a parachute.
- Lla « Turnaround » Speed: A team of just one technician and five conscripts can refuel, rearm, and inspect a Gripen for an air-to-air mission in under 10 minutes. This high « sortie rate » allows a small fleet of Gripens to act like a much larger force.
- Volvo RM12 Engine: Based on the General Electric F404 (used in the F/A-18 Hornet), Volvo modified the engine to be more reliable for single-engine operations and more resistant to bird strikes—a common hazard when flying low-level missions over Swedish forests.
- Advanced Data Link (TIDLS): Sweden was a pioneer in data-linking. A Gripen can share its radar view with other Gripens or ground stations silently, allowing one aircraft to track a target while another, with its radar turned off, sneaks in for the kill.
Global Reach & Evolution
- Lla « C » Standard: The JAS 39C was the first version to be fully NATO-compatible, featuring color cockpit displays, a retractable refueling probe, and English-language interfaces.
- International Operators: Beyond Sweden, the Gripen C/D is operated by South Africa, Hungary, the Czech Republic, and Thailand. It is also used by the UK’s Empire Test Pilots’ School (ETPS) as a premier training platform for future test pilots.
- Precision Arsenal: It was the first fighter in the world to be integrated with the Météore long-range missile and can carry a vast array of international weapons, including the IRIS-T, GBU-series bombs, and the RBS-15 anti-ship missile.
- The Gripen E: The newest evolution, the JAS 39E (Gripen E), is currently entering service. It is a significantly larger aircraft with a more powerful engine (GE F414), AESA radar, and much greater fuel capacity.
