Saab JAS 39 Gripen is a single-engine, multirole combat aircraft developed and produced by Saab AB for the Swedish Air Force and international customers. Designed to replace the Saab 35 Draken and Saab 37 Viggen, the aircraft emphasizes cost-effectiveness, avionics integration, and short-field operations for defense of Swedish airspace and expeditionary deployments. The Gripen program involved partnerships with firms and agencies in United Kingdom, Brazil, Czech Republic, Hungary, and South Africa among others.

Development

The Gripen emerged from Sweden's need to modernize after the Cold War under programs led by Swedish Defence Materiel Administration and Saab, building on lessons from the Fighter Aircraft Development milieu that included the McDonnell Douglas F/A-18 Hornet and Dassault Rafale projects. Initial concept studies in the 1970s and 1980s considered alternatives like derivatives of the General Dynamics F-16 Fighting Falcon and indigenous designs influenced by experiences with the Saab 35 Draken and Saab 37 Viggen. Flight testing began with prototypes at Saab's facility near Linköping, culminating in a maiden flight on 9 December 1988. Political decisions by the Swedish Government and procurement negotiations with export customers such as Czech Republic and Hungary shaped production orders in the 1990s.

Design and Features

The Gripen uses a delta wing and canard configuration with a single Volvo RM12 turbofan derived from the General Electric F404, emphasizing low procurement and operating costs compared with contemporaries like the Eurofighter Typhoon. Avionics integration incorporates a multimode pulse-Doppler radar and a comprehensive electronic warfare suite interoperable with systems used by NATO partners and operator nations such as Brazil and South Africa. The cockpit features a wide-angle head-up display and a hands-on throttle-and-stick setup drawing from ergonomic research at Lund University and industrial partners. Structural design allows short takeoff and landing from dispersed road bases, a concept practiced in partnership exercises with units from Swedish Air Force and allied formations from Royal Air Force and United States Air Force.

Operational History

Service entry with the Swedish Air Force in 1997 initiated deployments across Baltic and Nordic airspace, including interception missions related to incursions near Gotland and exercises with NATO members such as Norway and Denmark. Export orders led to operational squadrons in the Czech Air Force, Hungarian Air Force, Royal Thai Air Force, South African Air Force, and Brazilian Air Force, each undertaking training programs at national bases and joint exercises like Red Flag and Tactical Leadership Programme. The type has seen various operational roles from air policing to maritime strike, cooperating with platforms such as the P-3 Orion and NHIndustries NH90 in multinational operations.

Variants

Production and development spawned multiple variants: the original A/B two-seat trainers and single-seat fighters in Swedish service; the upgraded C/D with enhanced avionics and datalink capabilities for export customers; and the E/F series featuring a more powerful engine, AESA radar, and increased fuel and payload capacity in collaboration with partners such as SAAB Brasil and contractors from United Kingdom and United States. Specialized demonstrators and proposals targeted markets competing with the Lockheed Martin F-35 Lightning II and Boeing F/A-18E/F Super Hornet.

Operators and Deployment

Current operators include the Swedish Air Force, Czech Air Force, Hungarian Air Force, South African Air Force, Royal Thai Air Force, and Brazilian Air Force, with varying fleet sizes deployed at bases such as F7 Såtenäs and F17 Kallinge in Sweden and Anápolis Air Force Base in Brazil. Deployments have supported NATO air policing missions over the Baltic States and bilateral defense cooperation with nations including United Kingdom, United States, Denmark, and Norway. Export campaigns targeted procurement competitions in countries like Switzerland and Finland and involved industrial offsets negotiated with national ministries of defense and agencies such as Försvarets materielverk.

Upgrades and Modernization

Modernization efforts include integration of an active electronically scanned array (AESA) radar, new electronic warfare and self-protection systems compatible with suites fielded by Israel Aerospace Industries and Raytheon Technologies, and upgrade packages for datalinks and mission systems to enable network-centric operations with platforms like the E-3 Sentry and Gripen E/F interoperable assets. Collaborative upgrade programs with partners such as Embraer in Brazil and subcontractors in the United Kingdom addressed structural life-extension, avionics open-architecture migration, and weapons integration including beyond-visual-range missiles like the MBDA Meteor and short-range systems like the AIM-9 Sidewinder.
