Gripen Information pool.....

[N3oN]

Now, I think with the upcoming rumours and the activities in the recent past we are in need of analysing the new Gripen E platform.. please share related technological data about the same.... I personally really wanna know how capable is this fighter .. And whether it is right to procure this fighter aircraft in a hostile 5 generation environment of the future. Please don't pay too much attention on political part. Such discussion are futile. We just wanna discuss how capable this fighter is as compared to our current Indian fleet including Rafael.

The next generation Gripen, the Gripen E, is built to adapt to changing threats and operational requirements that modern air forces face.
Based on the proven Gripen C/D platform, the Gripen E (also referred to as Gripen E/F) carry this heritage and continues to be one of the most advanced multi-role fighters in the world - revolutionary because it combines advanced technology and operational effectiveness in an affordable package that no other fighter aircraft can even hope to match.


TRUE MULTI-ROLE FIGHTER
Gripen E is a fully NATO-interoperable, true multi-role fighter with outstanding availability, tailored for the future Network Centric Warfare (NCW) environment. Gripen E will meet the demanding operational requirements of the 21st century air forces and its unrivalled multi-role capability provides excellent tactical flexibility.

OPERATIONAL DOMINANCE
Gripen E offers operational dominance and flexibility with superior mission survivability. Air-to-air superiority is guaranteed with METEOR, AMRAAM, IRIS-T, AIM-9 missile capability and supercruise. Air-to-surface capability is assured through the use of the latest generation precision weapons and targeting sensors. Gripen E's superior situation awareness is ensured through an AESA radar, IRST passive sensor, HMD, cutting-edge avionics, next generation data processing and a state-of-the-art cockpit.

NETWORK CENTRIC WARFARE
Together with proven Network Centric Warfare capabilities including advanced data communications, dual data links, satellite communications and video links, make Gripen E the ideal independent fighter of choice. On-board sensors, in combination with HMD/NVG, deliver the ability to detect and destroy a wide variety of targets, even at night or in poor weather conditions.







AESA stands for Active Electronically Scanned Array and means that, in contrast to older generation radars, it has not only one antenna but a full array of small antennas, called elements. This means that the radar can simultaneously and independently track different targets, and also track targets independently of search volumes.











Gripen E is a Network Centric fighter and can communicate two ways with all armed units. It has a secure and multi-frequency data links system that provides total situation awareness. The acquired information – along with information about each Gripen’s position, fuel and weapon status – is shared with other Gripen fighters via the data link.






Gripen E is built for high survivability in a combat environment. Gripen tactics are based on smart use of a variety of electronic warfare capabilities. The RWR (Radar Warning Receiver) is the source for an accurate sensor for detecting emitting threats such as radar. And the Missile Approach Warning (MAW) system can detect and track incoming missiles of all types.






IRST an electro-optical system mounted on top of the nose, just in front of the canopy, and is looking forward in a wide sector registering heat emissions from other aircraft, helicopters and from objects on the ground and sea surface. The tactical advantage of a passive sensor is that it will not give your position away.










Almost any weapon can be integrated, giving Gripen E very high weapon flexibility. This is partly due to the flexible avionic architecture. Because of its well-documented ease of new weapon integration, Gripen served as the main test platform for Meteor, the latest long range air to air missile.






The highly advanced EW system can function as a passive or active sensor, warning for incoming missiles or radar looking at you. It can also be used for electronic attacks and jamming other radars. Coupled to the countermeasure such as chaff and flares the EW system can enhance the survivability.

MULTI-ROLE CAPABILITY
Gripen E has weapons for all types of mission, from guided glide bombs for precision engagement with low collateral damage, to long-range and agile air-to-air missiles and heavy anti-ship armaments. Additionally, the aircraft has an inherent precision strike and stand-off capability.



The single-seat Gripen E is equipped with a 27 mm Mauser BK27 gun. This can be used in air-to-surface attacks against land and sea targets and is suitable for air policing missions. Gripen NG can also carry pods and sensors for reconnaissance and special missions. These include Litening, Reccelite, DJRP and MRPS pods.



It is one of the easiest aircraft of its kind to add new weapons to. This makes it a favourite among weapons companies as they can quickly and easily use Gripen for development. For example, it was selected for testing the Meteor missile. This benefits users, as new armaments are available to them more quickly compared to other aircraft

SAAB's Gripen NG Fighter Has An Awesome Way To Make Its Radar More Capable

AESA radars have changed aerial combat, offering a quantum leap in range, resolution, fast scanning capabilities, stealthiness and reliability among many other advantages. But, an AESA’s somewhat narrow field of view can still be an issue. SAAB has come up with a ingenious solution to this problem—spin an angled AESA radar array around on a platter.

This system, which is called a repositioner, is ingenious as it allows the Gripen NG’s Raven ES-05 radar to gain another 40 degrees of scanning ability to either side of the aircraft’s nose. This is in addition to the 60 degrees AESA radar sets typically provide (120 degrees combined).


The ability to take a beyond-visual-range missile shot, then turn 90 degrees, while still providing mid-course updates for the missile fired and keep situational awareness at its peak is a great thing, and it opens up many tactical advantages for Gripen NG crews.

This system will allow beaming into the enemy’s radar notch without losing track of the bad guys. Beaming is when a fighter turns around 90 degrees away (perpendicular) from the enemy’s pulse doppler radar array. Because these types of radars use doppler shift to gauge a target’s relative velocity, and as such they filter out low relative velocity objects, especially ground clutter, the beaming fighter, which is not moving to or away from the enemy radar much while beaming, can enter the enemy radar’s notch.

This is a blind spot where the radar’s velocity gate, which acts like a filter, sees a target at low enough speed from its perspective that it discounts it. So even though the fighter may be moving at 500 mph, the right angle to the radar makes it only detect maybe 60 mph of closure, as such it throws this information out as it would ground clutter. This is an especially useful tactic when the enemy fighter is above you, and trying to lock you up in the look-down-shoot down scenario.


ADVERTISEMENTThe issue is that with a typical fixed AESA radar array, pulling off such a maneuver means the fighter doing so will lose its radar picture and lock on the enemy it is trying to evade. Without third party sensors feeding this data to the beaming fighter via data-link, its pilot will become blind to the tactical situation when it matters most.

Now, with a system like SAAB’s repositioner, the radar can be rotated to gain the extra azimuth to continue scanning the area over 90 degrees off its nose. As such, the pilot will not lose situational awareness and their missiles can continue to get mid-course updates as they fly towards their targets. Paired with low-probability of intercept mode, where the AESA radar uses very directed beams of radar energy in quick succession, and while hopping frequencies, the fighter that is beaming can be hard to detect even by passive sensors, such as radar warning receivers.
With new missiles that have extreme ranges, like MBDA’s Meteor, a Gripen NG could fire these missiles at enemy fighters at long-ranges, and then jump into the enemy’s doppler notch to hide while still guiding its missiles. This could put the Gripen NG beyond the reach of the enemy’s infrared search and track system (IRST) that is impervious to jamming or beaming tricks during the entirety of the engagement, as well as the enemy’s radar for much of it. As such, the enemy fighters would not be able to detect the Gripen even while its missiles are well on the way. First shots, first kill.

Other solutions to this problem have been designed into other fighters. The F-22 Raptor was supposed to have AESA radar arrays on both sides of its nose in order to give the jet more radar coverage at extreme angles. Sadly, the equipment was never installed due to budget reasons. Still, the F-22, with its low observability (stealth) really has less a need for such a system than less stealthy aircraft.

Unlike the F-22, Russia’s T-50 has side-mounted AESA arrays, which may be necessary due to the aircraft’s less stealthy design when compared to the F-22. The Eurofighter consortium also has an answer to this problem with their swashplate design tied to the CAPTOR-E radar, which is very similar to SAAB’s repositioner.


With the 4.75 generation fighter marketplace looking to be stable much longer than originally anticipated, AESA radar upgrades breathe new life into not so new designs. The Gripen NG in particular packs a ton of capability into a small package, and it will be interesting to see how the jet does once it becomes operational.

Currently, Brazil has an order for 36 of the jets (24 single-seat Gripen Es and 12 two-seat Gripen Fs) that should begin being delivered by 2019, and Sweden will order 60.
