When designing the successor aircraft "Viggen" was staged to create a set plane with the main function - interceptor, and secondary - an attack ground circuit provided, to the new aircraft would be more Saab-37 only 60-65%, and half the weight of its. "Saab" company, "Volvo Flyugmotor", "Ericsson" and FFV organized JAS industrial group to develop a new multi-purpose aircraft. AT 1982 g. signed contracts to build five prototypes JAS 39.

In June 1984 g. Sweden's parliament approved a draft JAS (fighter, Sturmovik. scout) to create a "Gripen" third-generation fighter aircraft. Construction of the first prototype JAS 39 It was completed 26 April 1987 city, its first flight 9 December 1988 g. During the sixth test flight 2 February 1989 g. due to failure of the flight control system prototype crashed, which required improving the management system. Corrections mainly software were made in the USA on a modified aircraft T-33. There were problems with the propulsion RM12, who suffered from cracks and the surging of the compressor blades. Therefore, the production aircraft first flew 10 September 1992 city. and not in 1990 g. as originally planned.
JAS 39 "Gripen" is a single-seater, made by a "duck", single-engine, located in the fuselage. Glider is designed for maximum operational overload 9. cockpit with a drop-shaped lantern sealed. Ejection seat S10LS provides emergency evacuation of the airplane in the parking lot. chassis tricycle, unicycle with the main struts and the two-wheeled nose, intended to land with a large vertical velocity. Turbofan engine afterburner designed based on American GE F404 engine and is compared with an initial increase in 5% air consumption. Fuel-sealing is located in the fuselage tanks. fuel control system can control the centering plane. Installation of external fuel tanks with a capacity of 500 or 1000 l. There are two main hydraulic system and one backup.
The aircraft is aerodynamically unstable for most loads of options and modes of flight. Artificial stability is ensured with the three-channel digital FBWCS redundancy scheme. There is also a built-in back-up analog system. Deviation control system by means of hydraulic actuators.
It provides multi-mode search engine PS-05A. Used SDS computing system 80, consisting of 40 microcomputer, AMR set the connected equipment 345, laser INS, demon-platform and heading, EP Electronic Display 17, including a wide-angle diffraction HUD with a video camera FD5040. Arming includes built gun Mauser VK27 (caliber 27 mm) and suspension arms on the seven external sites, which may consist of SD class "air-to-air» »RB71« Sky Flash "". RB74 (AIM-9L) Sayduinder” or AIM-120, as well as SD-class "air-surface" "Maverick", ПКР RBS-15F, bombs, NAR and cluster munitions.
In October 1991 g. I began to develop a two-seater training aircraft JAS 39B "Gripen". The first aircraft was handed over to the Swedish Air Force 8 June 1993 g.
