Den Saab JAS 39 Gripen (engelska: "griffin") är ett lätt enmotorigt flermotorigt stridsflygplan tillverkat av det svenska rymdföretaget Saab. Den är utformad för att ersätta Saab 35 Draken och 37 Viggen i flygvapnet. Gripen har en deltavinge- och kanardkonfiguration med avslappnad stabilitetsdesign och fly-by-wire-flygkontroller. Den drivs av Volvo RM12 och har en topphastighet på Mach 2. Senare flygplan modifieras för Natos driftskompatibilitetsstandarder och för att utföra tankning under flygning.

The “JAS” Philosophy

Den 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), Attack (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.
The “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

The “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 Meteor 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.
