A two-seat "New Technology Demonstrator" has been built,[15] and was presented on 23 April 2008. It has increased fuel capacity, a more powerful powerplant, increased payload capacity, upgraded avionics and other improvements. The new aircraft is also referred to as the "Gripen Demo",[16][17] the "Gripen E/F", or MS21.[18][19]
The new Gripen NG (Next Generation) will have many new parts and will be powered by the General Electric F414G, a development of the F/A-18E/F Super Hornet's engine. The engine will produce 20% more thrust at 98 kN (22,000 lbf), enabling a supercruise speed of Mach 1.1 with air-to-air missiles.[20]
Compared to the Gripen D, the Gripen NG's max takeoff weight has increased from 14,000 to 16,000 kg (30,900–35,300 lb) with an increase in empty weight of 200 kg (440 lb). Due to relocated main landing gear, the internal fuel capacity has increased by 40%, which will increase ferry range to 4,070 km (2,200 nmi). The new undercarriage configuration also allows for the addition of two heavy stores pylons to the fuselage. Its PS-05/A radar adds a new AESA antenna for flight testing beginning in mid-2009.[20]
Gripen Demo's maiden flight was conducted on 27 May 2008. The test flight lasted about 30 minutes and reached a maximum altitude of about 6,400 meters (21,000 ft).[21] On 21 January 2009, the Gripen Demo flew at Mach 1.2 without reheat to test its supercruise capability.[22][23][24]
Saab performed study work on a aircraft carrier based version in the 1990s. In 2009, Saab launched the Sea Gripen project in response to India's request for information for a aircraft carrier aircraft. Brazil also has a potential carrier aircraft need.[25][26] Sweden awarded Saab a four-year contract in 2010 to improve the Gripen's radar and other equipment, and lower its operating costs.[27] In June 2010, Saab stated that Sweden plans to order the Gripen NG under the JAS 39E/F designation. The new variant is to enter Swedish service in 2017 or possibly earlier if export orders are received.[19]
