Gripen E Taxi testing
Gripen E is an enhanced version of the Gripen C/D multi-role aircraft. Saab started the construction of the pre-production Gripen E test aircraft, designated as 39-8, in July 2013. Initial construction works involve the assembly of the aircraft’s front fuselage, while the payload mounting works will be carried out by RAUG.
New equipments to be integrated into the Gripen E were tested and proved in the Gripen 39-7 E/F demonstrator programme during which the test aircraft has flown for more than 250 hours in Sweden, the UK, India and Switzerland since 2008. The testing of the Gripen E is being overseen by Armasuisse.

The Gripen Demo aircraft (serial 39-7) is a converted JAS 39D that has been used to help de-risk the Gripen E program since 2008, testing a number of new capabilities for the project ahead of the main development contract, which is now in place.
The Demo aircraft (39-7) has demonstrated the initial pre-production AESA radar, the missile approach warning system (MAWS), the new F414-GE-39E engine, SATCOMs, new displays and avionics architecture (in the back seat), increased internal fuel, new landing gear, two new stores stations, the new digital head-up display (HUD), the Selex Skyward-G IRST and now a production Selex ES-05 Raven AESA radar.

Structurally things have also changed. The outer wings now attach farther out — at pylon three — to make for extra internal space for fuel tanks, and new aluminum-lithium integral frames are provided for the wing attachments. The main gear retracts into the wing now, rather than the fuselage. There are larger engine air intakes and a new secondary environmental control system (ECS) for the powerful AESA radar at the bot-tom of the fin leading edge. A revised wingtip design accommodates new electronic warfare antennas. Although the canopy, seat and outer elevons are taken from the Gripen C, this is a very new beast. Source @key.aero

The aircraft is also being considered by several other countries and the contract provides an option for Saab to award the manufacturing of additional complete landing gear systems to Héroux-Devtek……
Gripen E fighters getting pneumatic missile eject launcher pylons
Pneumatic missile eject launcher pylons are to be developed and supplied to Saab of Sweden by Excelis under a long-term agreement.
Exelis said the pneumatic missile eject launcher pylons, or PMEL, will be for use on Saab’s Gripen E fighters and allow the powered ejection of Meteor and AIM-120 advanced medium-range air-to-air missiles from the underside of the aircraft fuselage.
“This is a great opportunity for us to build on Exelis weapon carriage and release experience and continue to grow in the air-to-air missile eject market,” said Ken Harrison, vice president and general manager of International Night Vision and Communications Solutions at Exelis.
Exelis said signature of the agreement between the two companies released an immediate design and development phase contract, which includes the delivery and supply of several flight-trial units. A later initial production contract will provide for the supply of 214 PMEL units to Saab.
Work under the contract will be conducted at Exelis’ facility in Brighton, England. Source @spacedaily.com
Gripen E design details
The Gripen E has an overall length of 15.2m, wingspan of 8.6m, and maximum takeoff weight of 16,500kg. The maximum speed of the aircraft is Mach 2 at high altitude, whereas the speed at low altitude is 1,400km/h.
The one seater aircraft features ten pylon stations, which enable it to carry reconnaissance pods, weapons and external fuel tanks. Its turnaround time is ten minutes in air-to-air configuration and 20 minutes while carrying weapons for air-to-ground combat.
The aircraft’s internal fuel tanks with a combined capacity of 3.4t are approximately 40% larger than those of its former version. The increased volume is made possible by moving the landing gear from the fuselage of the aircraft out to the inner wings.
The Gripen E features a digital state-of-the-art cockpit. The cockpit also features a hands-on-throttle-and-stick (HOTAS) which provides superior situational awareness for the pilot.

Gripen E the Su-35 killer: Here
Highlights of above post:
“Simulation has the Gripen E shooting down the Su-35 at almost the same rate that the F-22 does. The Gripen E is estimated to be able to shoot down 1.6 Su-35s for every Gripen E lost, the F-22 is slightly better at 2.0 Su-35s shot down per F-22 lost. In turn the Su-35 is better than the F-35, shooting down 2.4 F-35s for each Su-35 shot down. The Su-35 slaughters the F-18 Super Hornet at the rate of eight to one, as per General Hostage’s comment. How that comes about is explained by the following graphic of instantaneous turn rate plotted against sustained turn rate:
Turning, and carrying a gun, remains as important as it has ever been. Most missiles miss in combat and the fighter aircraft will go on to the merge. Assuming that pilot skill is equal, a 2° per second advantage in sustained turn rate will enable the more agile fighter to dominate the engagement. A high instantaneous turn rate is vital in being able to dodge the air-to-air missiles in the first place. The aircraft on the upper right quadrant of the graph will have a higher survival rate. The ones on the lower left quadrant will produce more widows.”
Gripen operational cost lowest of all western fighters: Jane’s
“The operational cost of the Swedish Saab Gripen aircraft is the lowest among a flightline of modern fighters, confirmed a White Paper submitted by the respected international defense publishing group IHS Jane’s, in response to a study commissioned by Saab.
For the purpose of modeling to create a standard or benchmark, the study arrived at the ‘aircrafts’ fuel usage, hence cost, based on a theoretical one hour sortie at max dry thrust’, not ‘necessarily reflective of actual fuel consumption and hence fuel cost of a one hour sortie’.
As is evident, the modeled cost pattern is closest to the derived cost pattern in the case of the Gripen, F-16, Rafale, and Eurofighter. The research and the model digress in the case of the F-35 and the F/A-18.
In the case of the F-35, the study says the different ‘costs arise from the differing power and specific fuel consumptions of the A / C and B models. The B model is the top figure in both cases’. The study says, “The single P&W F-135 engine is relatively fuel efficient for its power, resulting in a lower fuel burn at maximum dry thrust than might be expected.” It adds that, although obviously, ‘accurate CPFH for in-service aircraft does not exist’, ‘the US and Australian forecast costs both suggest it will not offer lower CPFH than current aircraft’, considering ‘the aircraft itself is an extremely sophisticated design carrying a large number of new and unproven onboard systems’.”

Meteor Beyond-Visual Range Air-to-Air Missile, Meteor is air ramjet-powered missile with advanced seeker technology that can fly at sustained high speeds, over long ranges and with great agility to defeat air-to-air threats range 100-300 km at over Mach 4
The aircraft also has the flexibility to be fitted with Sidewinder and A-Darter missiles to replace the IRIS-T, and the Advanced Medium Range Air-to-Air Missile (AMRAAM) missile to replace the Meteor. It can further be fitted with long range weapons such as R-Darter and Derby, and short range weapons such as ASRAAM and Python. It is guided by two-colour thermal imaging infrared homing with laser fuse. It features a multimode electronic counter countermeasures (ECCM) suite for higher view angles.
AIM-9 Sidewinder (Rb.74) Anti-Aircraft Missile
The A-Darter is 2.98m (9.78ft) long and 0.16m (0.52ft) in diameter. It has four fixed delta control fins at the rear and two strakes along the sides. The missile weighs 90kg. It carries a high explosive (HE) warhead and has a range of ten kilometres. It is powered by a solid propulsion system. The missile has a track rate of 120°/s and a seeker angle of 180° for countermeasure resistance. It also features lock-on after launch and memory tracking for higher range intercepts, and is compatible with Sidewinder stations. The tail-controlled AAM is powered by a boost-sustain rocket motor and uses thrust vector flight control. Its wingless airframe and low drag enable the A-Darter to have a higher range than the traditional SRAAMs. The missile system is designed with a highly agile airframe for close combat in electronic countermeasures (ECM) environments.

Advanced Medium Range Air-to-Air Missile
AIM-120 AMRAAM range 105-180 km at Mach 4
The R-Darter is a beyond visual range (BVR) air-to-air missile guided by an active radar homing seeker. It was designed and manufactured by the South African firm Kentron, now known as Denel Dynamics. The South African air-to-air missile program benefited from cooperation with Israel during the 1980s and the R-Darter is very similar to the Python Derby. >60 km (>37 mi) Active radar homing guidance system.
The Derby missile is a medium-range active radar homing missile from Rafael’s Python family of missiles. The missile is basically an enlarged Python-4 with an active-radar seeker. It is similar to the AIM-120 AMRAAM. It has a range of 50km and can hit target at Mach 4.
ASRAAM (Advanced Short Range Air-to-Air Missile) is the next generation infrared-guided missile designed and built by MBDA UK (formerly Matra BAe Dynamics) to provide enhanced aerial combat capabilities for fighter aircraft. The ASRAAM missile can be deployed to engage targets within visual range (WVR) combat operations. It offers high speed and exceptional agility during its flight time. It is capable of engaging targets under complex environmental conditions and is compatible with aircraft armed with Sidewinder or AMRAAM missiles. The ASRAAM weapon is guided by an advanced, accurate focal plane array Imaging Infra-Red (IIR) seeker developed by Raytheon. The passive homing guidance system provides the ability to significantly track, acquire and engage targets beyond visual range (BVR) under severe clutter and countermeasures environmental situations. A low signature rocket motor is fitted to drive the ASRAAM short range missile. It provides superior acceleration and range throughout the flight. The motor also allows ASRAAM to quickly intercept any target and gives it a speed of about Mach 3. Source @airforce-technology.com
Python-5 is a fifth generation air-to-air missile (AAM) manufactured by Rafael Advanced Defense Systems. The missile can engage enemy aircraft from very short ranges and near beyond visual range. Python-5 is the most accurate and reliable AAM of the Israeli Air Force and one of the most sophisticated guided missiles in the world. Python-5 features a new electro-optical infrared seeker with high off-boresight capability. The infrared seeker scans the target area for the threat and locks-on for terminal chase after the target is identified. Python-5 is also equipped with lock-on-before launch (LOBL) and lock-on-after launch (LOAL) capabilities. In LOAL mode, the target information is transmitted from the launch aircraft to the missile. Python-5 is powered by a solid propellant rocket engine. The propulsion system provides a speed of Mach 4 and an operational range of more than 20km. Source @airforce-technology.com
The Gripen E can also be integrated with a number of air-to-surface weapons including unguided Mk82, Mk83 and Mk84 bombs, laser-guided bombs such as GBU-12, GBU-16 and GBU-10, and advanced bombs such as GBU-49 and GBU-39.

Gripen E’s radars, sensors and communication systems
The Gripen E is fitted with Selex’s ES-05 Raven active electronically scanned array (AESA) radar system. Fitted on a swashplate at the nose of the aircraft, the radar provides an angular field of view of 100° and look behind capability.
The Gripen takes it one step further by mounting the radar on a “repositioner” that allows +/-100° scan angle. Typically, AESA radars are fixed, and “steered” virtually. It’s simpler than it sounds. Here is the Gripen E’s radar:
Advantage of swashed plate array of RAVEN ES-05 radar
In long-range air-to-air combat, the highest FoV means that a Gripen can maneuver at an angle in relation to the viewed axis of the target (off-boresight angle) greater than what is possible with an AESA radar with fixed TRMs matrix after launching a BVR missile and still be able to send updated information to the missile. In turn, a potential enemy will be limited to deviating up to 60º of the viewed angle after launching the BVR missile. Therefore, it will still be displacing towards a missile launched by Gripen while this, in turn, will be flying perpendicularly or even away from the enemy missile. Simulations made showed that this capacity should not be underestimated and it will have a devastating effect in the engagement result of the BVR. Source @jaihind971.blogspot.com

Skyward-G can silently detect threats, at beyond-visual range without relying on active (radar) emissions that could betray the aircraft’s intentions and position to hostile forces. With the IRST a Gripen can detect and track enemy targets, including aircraft, naval vessels and ground vehicles. The system can also complement the radar by tracking the heat signatures of stealthy targets that are not visible or trackable by radar.
Finmeccanica, through its Airborne and Space Systems division, has signed contracts to provide Identification, Friend or Foe (IFF) systems for the Gripen Next Generation (Gripen NG) aircraft earmarked for the Air Forces of Sweden and Brazil.

The systems will be used by Gripen pilots to identify other aircraft or vehicles as friendly (or potentially unfriendly) and to determine their bearing and range from the aircraft. Independent from the Gripen NG’s radar and other sensors, the system can look in a different direction, allowing the pilot to use the radar to queue-up targets for subsequent identification. Of particular note, the system’s separate antennas give it a wide, more-than 180 degree field of regard, providing operational benefits.
Each complete system consists of a transponder and an interrogator. Also included is a crypto customised in accordance with customer requirements. The transponder, which is the company’s Mode 5 M428 model, is the same being offered to the UK MoD to address NATO’s requirement for a new standard of IFF across all platforms. Source @avionews.com

The Elisra passive airborne warning system (PAWS-2) has been selected for the Gripen fighter. Elbit, Elisra’s parent Israeli company, said that the system was selected “following a comprehensive in-depth evaluation and testing in various scenarios as well as in a comparative live fire test.”
The missile approach warning function on the Gripen has previously been provided by Saab itself, as part of the Swedish company’s Integrated Defensive Aids System (IDAS) that has also been installed on other combat aircraft, helicopters and airlifters. IDAS includes the MAW-300, which employs ultraviolet (UV) sensors, whereas PAWS-2 is an infrared (IR) system. Elbit said that PAWS-2 is based on years of experience and has growth potential “to cope with ever-growing future requirements expected during the life-cycle of the Gripen fighter system.”
A Saab spokesman told AIN that PAWS-2 would be the baseline fit for all future Gripens but that individual customers would be free to select and integrate alternatives. The Gripen has just been chosen by Brazil, and Saab is currently campaigning to sell the fighter to Malaysia and Switzerland, having secured an order for 60 from the Swedish air force. The Swedish aircraft will be converted from Gripen Cs that are already in service. Switzerland will get 22 new aircraft, if a nationwide referendum next year confirms the purchase.
