Saab JAS 39 Gripen Info # 2

Link to first thread and the first post with many links to Gripen info such as info on range, speed, rcs, service, radar, airframe, EW package etc.

——————-

Quick summary on the different main models:

Gripen NG is 3% heavier than JAS 39C but comes with over 22% more engine thrust.

Gripen NG Range
Range is increased an average of 40% over the JAS 39C as both the internal and external fuel capability is expanded.

Combat radius: 1,300 Km + 30 minutes on station with A2A weapons.
Range (one-way): 2,500 Km on internal fuel
Ferry range (one-way): 4,075 Km with external fuel
Combat Radius estimate: 1,800 km with A2A weapons

One drop tank (450 Gal) gives the Gripen NG an extra range of approximately 1000 km.

AESA

The aircraft has been in the workshop since early April being readied for its second test phase. This will introduce missile approach warners and satellite communications equipment and, from later this year, an active electronically scanned array (AESA) radar: Selex Galileo’s Vixen 1000E/ES05 Raven.

Saab rolled out the Demo with an agreement to use an AESA demonstrator provided by Thales, but their relationship quickly crumbled. Thales says it withdrew the technology as it was already under contract for the Rafale, but Kemp gives a different explanation. “The radar wasn’t good enough for what we needed to do,” he says. “The Selex radar is seriously outstanding. When you brief people on the capabilities they are astonished.”

Bob Mason, Selex Galileo’s executive vice-president, radar and advanced targeting, says the Vixen 1000E’s advantage comes from the use of a swashplate mounting, which enables the active array to be rotated by +/-100°. This beats a fixed AESA during beyond visual-range and off-boresight missile firings, and while acquiring synthetic aperture radar imagery, he says. “We will be delivering a prototype this year for them to fly, and then will upgrade it over the next 18 months.”
