-------------------------------------

Gripen Demo will be a heavier aircraft (empty weight adds 300 kg to 8,100 kg, max. takeoff weight rises from 14,000 kg to 16,000 kg) with increased external and internal fuel capacity (internal fuel rises 38%, and…) and an increase from 8 to 10 weapon/fuel pylons. To offset this extra weight, Gripen Demo will use a higher-thrust GE/Volvo F414 engine variant, replacing the GE/Volvo F404 variant in current aircraft and giving the aircraft a 25%-35% power boost. Other improvements include an next-generation AESA radar (probably drawing on Ericsson's "Nora" project), along with improved computing and avionics overall, including satellite communication, Link 16 capability added to the Gripen's existing datalink, and improved electronic warfare via jammer pod integration and other measures. Gripen Demo's corporate participants include Saab


Engine: Volvo Aero RM12 (developed from GE F404 with the changes being at least new fan, afterburner flame holder and accessories, partly to make it more suitable to a single engine aircraft)
Max thrust: approx 54 kN, 80.5 kN with reheat, airflow 68 kg/s, compression ratio 27.5:1, mass 1055 kg, overall length 4.04 m, diameter 0.884 m, inlet diameter 0.709 m

--------------------------------

Radar: Ericsson PS-05/A pulse doppler radar (can count anchored ships and follow road traffic at at least 90 km and detect typical fighter sized targets at 120 km).
will be replaced with the next generation AESA radar (NORA)

Total mass 156 kg, antenna assembly 25 kg, antenna diameter 0.600 m,
Max power consumption 8.2 kW (114/200V 400Hz AC) and 250 kW 28V.

Predicted MTBF: 170 hours (air operation) Cooling air: 85g/s at 0oC, Cooling liquid: 3.5kW to be absored. Electrical interface: MIL-STD-1553B data bus and fibre optic video output to the display system.

Air to air scanning at 60 (at first 50) deg/s in either 2 120 deg bars, 2 60 deg bars or 4 30 deg bars. Surface mapping and search across 5 x 5 km to 40 x 40 km with GMTI speed adjustable by the pilot.

Four basic air to air modes: Track While Search, Priority Target Tracking gives higher quality tracking for multiple targets, Single Target Track gives highest quality data, Air Combat Mode for short range search and automatic target capture.

Targeting pod: Litening, with FLIR and laser designation.

The Gripen's built-in armament consists of a single Mauser BK-27 27 millimeter cannon, housed in a fairing on the aircraft's belly, offset to left to the rear of the engine intake. Given the aircraft's relatively small size, it generally carries guided weapons to ensure maximum combat effectiveness.

----------------------------------

New Features Gripens NG include:

* An electronically-scanned array (AESA) radar based on the PS-05/A, now being developed by Ericsson. An AESA consists of an array of programmable "transmit-receive (TR)" modules that can operate in parallel to perform separate or collaborative functions, performing, for example, jamming and target acquisition at the same time. The AESA will provide enhanced multimode capabilities, as well as extended range for beyond visual range missiles. It is scheduled for introduction in the 2005:2010 timeframe.

* Improved defensive countermeasures, including new towed decoys and missile and laser warning systems.

* The "OTIS" infrared search and track (IRST) system now under development by Saab Dynamics and being tested on a Viggen. OTIS will provide multiple modes for both air to air and air to ground combat.

* The Thales "Guardian" helmet-mounted display (HMT), now being evaluated on the Gripen for cueing the IRIS-T and other smart weapons.

The Gripen's digital architecture makes software upgrades straightforward, at least as such things go. Possible software improvements include new radar and datalink modes; a new terrain-referenced navigation system; and a fully autonomous precision landing-guidance system. In the long term, SAAB is looking at a new engine, such as the General Electric F414 or a thrust-vectoring version of the EJ2000 engine used on the Eurofighter; conformal fuel tanks or a fuselage stretch for greater range; a wide-angle HUD; a binocular helmet-mounted display; a direct voice-command system; and an advanced missions support system.


----------------------------------

The Swedish Tactical Flight Combat Suit has been developed by FMV (The Swedish Defence Material Administration) and is mainly made by Swedish companies.

The requirements for the TFCS are:

  • 9 G sustained with high onset rate, at least 30 s after 6 G/s and at least 7 G after a gradual (0.1 G/s) onset without anti-G straining manoeuvre
  • Biological and chemical warfare protection
  • High altitude protection, including explosive decompression
  • Arctic climate and cold water survival
  • High temperatures (fire) protection both in cockpit and on the ground
  • Air blast protection for ejection speeds up to 600 kt
  • Thermal protection




-----------------------------------------
The aircraft is controlled by a digital fly-by-wire (FBW) system with triple redundancy and an analog backup. The analog backup system provides a simple, reliable capability, and is automatically activated if two of the three digital FBW systems go down. The pilot can also activate the analog system with the push of a button. The Gripen was designed from the outset to use the FBW system, which was evaluated on a modified Viggen. The FBW system compensates automatically for the degree of instability built into the Gripen to increase its maneuverability. The FBW system also allows the aircraft to adapt to combat damage, for example using differential control of the canards to fly the aircraft if the ailerons are disabled.


"The Gripen pilot can switch operational role in flight."


TIDLS (datalink)
One Gripen can provide radar sensing for four of its colleagues, allowing a single fighter to track a target, while the others use the data for a stealthy attack. TIDLS also permits multiple fighters to quickly and accurately lock onto a target's track through triangulation from several radars; or allows one fighter to jam a target while another tracks it; or allows multiple fighters to use different radar frequencies collaboratively to "burn through" jamming transmissions. TIDLS also gives the Gripen transparent access to the SAAB-Ericsson 340B Erieye "mini-AWACs" aircraft, as well as the overall ground command and control system. This system provides Sweden with an impressive defensive capability at a cost that, though still high, is less than that of comparable systems elsewhere.



TIDLS can connect up to four aircraft in a full-time two-way link. It has a range of 500 km and is highly resistant to jamming; almost the only way to jam the system is to position a jammer aircraft directly between the two communicating Gripens. Its basic modes include the ability to display the position, bearing, and speed of all four aircraft in a formation, including basic status information such as fuel and weapons state. The TIDLS is fundamentally different from broadcast-style links like Link 16. It serves fewer users but links them more closely together, exchanging much more data, and operating much closer to real time.

TIDLS information, along with radar, EW, and mapping data, appears on the central MFD. The display reflects complete sensor fusion: a target that is being tracked by multiple sources is one target on the screen. Detailed symbols distinguish between friendlies, hostiles, and unidentified targets and show who has targeted whom.

Today, Sweden is the only country that is flying with a link of this kind.
The Flygvapnet has already proven some of the tactical advantages of the link, including the ability to spread the formation over a much wider area. Visual contact between the fighters is no longer necessary, because the datalink shows the position of each aircraft. Leader and wingman roles are different: the pilot in the best position makes the attack, and the fact that he has targeted the enemy is immediately communicated to the three other aircraft.

A basic use of the datalink is "silent attack." An adversary may be aware that he is being tracked by a fighter radar that is outside missile range. He may not be aware that another, closer fighter is receiving that tracking data and is preparing for a missile launch without using its own radar. After launch, the shooter can break and escape, while the other fighter continues to pass tracking data to the missile. In tests, Gripen pilots have learned that this makes it possible to delay using the AMRAAM's active seeker until it is too late for the target to respond.

But the use of the link goes beyond this, towards what the Swedish Air Force calls "samverkan," or close-cooperation. One example is the use of the Ericsson PS-05/A radar with TIDLS. An Ericsson paper compares its application, with identical sensors and precise knowledge of the location of both platforms, to human twins: "Communication is possible without explaining everything."

"Radar-samverkan," the Ericsson paper suggests, equips the formation with a super-radar of extraordinary capabilities. The PS-05/A can operate in passive mode, as a sensitive receiver with high directional accuracy (due to its large antenna). Two PS-05/As can exchange information by datalink and locate the target by triangulation. The target's signals will often identify it as well.

The datalink results in better tracking. Usually, three plots (echoes) are needed to track a target in track-while-scan mode. The datalink allows the radars to share plots, not just tracks, so even if none of the aircraft in a formation gets enough plots on its own to track the target, they may do so collectively.

Each radar plot includes Doppler velocity, which provides the individual aircraft with range-rate data. However, this data on its own does not yield the velocity of the target. Using the TIDLS, two fighters can take simultaneous range-rate readings and thereby determine the target's track instantly, reducing the need for radar transmission.

In ECM applications, one fighter can search, while the wingman simultaneously focuses jamming on the same target, using the radar. This makes it very difficult for the target to intercept or jam the radar that is tracking him. Another anti-jamming technique is for all four radars to illuminate the same target simultaneously at different frequencies.

----------------------------------

STOL

The Gripen can take off and land in less than 600 meters (2,000 feet). Once deployed to a road base, the Gripens are serviced by a ground crew of six, including one highly trained specialist and five minimally trained conscripts. A service team can refuel and rearm a Gripen in ten minutes. The Gripen features an auxiliary power unit (APU) to reduce its dependence on ground systems, and the fighter's onboard digital systems include "built-in self-test" capabilities that can download diagnostic data to a tech's laptop computer. Service doors to critical systems are at head level or lower, allowing easy access by technicians. Pilots using the Gripen flight simulators have performed simulated carrier landings, without an arresting hook; it seems a bit unlikely that this will ever be done in practice, however.


The operational cost of Gripen is 50 per cent lower than any other aircraft in its class that is currently, or planned to be, in service. It is twice as reliable and easier to maintain than its competitors.



------------------------------------

On a CAP 385km from base, a Gripen can stay on station for two hours carrying 2X AMRAAM, 2X AIM-9 and 2X droptanks.

When carrying 3X 1000lbs GBU-16 on a LO-LO-LO strike profile, the Gripen has a mission radius of 648km. With 2X GBU-16's and extra fuel tanks radius increases to 833km.

Ferry range is 3500km according to Col Jan Jonsson of the Swedish Air Warfare Center.

The Gripen can accelerate from M 0,5 to M 1,1 in 30 seconds.

The Gripen can sustain M 1,1 using dry thrust, while carrying a droptank and AAM's.
supercuise

The Gripen can operate from 800m long and 9m wide roadstrips. Take off and landing distances can be down to 400-350 meters.

-----------------------------------

radar (JAS-39): 20% longer than RDY (M2000-5), and 40% longer than the AN/APG-68 for F-16C/D Block40/42.

7. While combating with the basic type of MIG-29 (MIG-29G??) in BVR engagement:

* JAS-39A: the effective range for Gripen to detect MIG-29 is 60 km longer than the effective range for MIG-29 to detect Gripen.


* F-16C/D: the effective range for Falcon to detect MIG-29 is 5 km longer than the effective range for MIG-29 to detect Falcon.

8. Maintenance of GRIPEN:
* The MTBF for JAS-39A is 7.6 flight hours, and the SAAB declared that the MTBF for the

USAF?s frontline fighters (except F/A-22 perhaps) is no more than 4.1 flight hours.

* The man hours of maintenance for each flight-hour: 12 man-hours initially, than reduced to 10 man-hours (F/A-18 E/F: 15 man hours of maintenance for each flight-hour).

* The charge for each flight-hour: 2,500 USD initially, than reduced to 2,000 USD.


----------------------------------------------------------


The resulting handling qualities give Gripen
the following distinct operational capabilities:

Netcentric Fighter – A truly Network Centric new generation
multi-role fighter with the world’s most highly developed
secure and multi-frequency data link, providing total situation
awareness for the pilot in all roles.

Superior Sensor Fusion – A fully integrated avionic mission
system operating on five 1553B digital data bus highways.
This provides total sensor fusion resulting in enhanced combat
capability guaranteeing precision delivery of smart weapons.

Smart Digital Cockpit – An advanced fully digital cockpit
layout with three large colour, Multi-Functional Displays (MFD)
and Hands-On-Throttle-And-Stick (HOTAS) provide the pilot
with a superior combat advantage. Don’t need, don’t show.

See First - Kill First – A combination of low radar, IR and
visual signatures, along with the long range PS05 multimode
radar and sensor fusion, including world leading new
generation weapon integration, ensure a high kill ratio in
long range engagements.

Outstanding Agility – The world’s most agile fighter for close
combat. A combination of advanced aerodynamic layout utilizing
a combined close-coupled canard – delta configuration and
a triplex, digital fly-by-wire Flight Control System (FCS) leads
to a winning dog-fight capability.

High Operational Tempo – Gripen’s high operational availability,
rapid turnaround and minimal support requirements lead to
sustained high sortie rates giving Commanders the ability to
meet the most demanding operations with minimum resources.
Affordability – Gripen achieves the lowest operating cost of
any fighter currently in operational service. This is accomplished
by combining advanced system design, high technology, modern
components and the highly reliable Volvo RM12 engine.

Future development – Gripen is built to be adaptable to
changing threats and operational requirements that a modern
air force faces. Gripen has significant growth available and
many features are implemented in software. This means that
modifications are much easier to design and implement. In
most cases costly hardware changes can be avoided.

------------------------------------------------------

"Information and situation awareness
are key factors in having the winning edge.
The ability to acquire, retrieve, process,
share and display tactical information
– such as positional data for hostile and
friendly units, missile engagement zones,
and information from radar warning
receivers – enables Gripen pilots to
operate and interact effectively, whilst
avoiding exposure to enemy fire."

---------------------------------------------------


what does the world and those who operate gripen say/think??


The purpose of the deployment was to enable the Gripen pilots to operate Gripen´s advanced electronic warfare (EW) systems and hone their skills in a dynamic environment. During the operational missions, which took place over a week, the pilots performed Close Air Support missions and executed air-to-ground attacks against targets defended by simulated surface-to-air missile systems.
During these attacks, the pilots took full advantage of Gripen’s superior EW-systems using both passive and active counter measures, including the dispensing of chaff and flares against hostile threats. In addition to these missions, the Gripen pilots also flew daily dissimilar air combat missions against the American F-15 Eagles.
All missions were carried out in a special training area at the RAF Spadeadam base. The SwAF Gripen deployment to the UK was also the first of such exercises between the Swedish Air Force and the US Air Force in Europ
he Gripens flew as part of the hostile ‘Red Force’, largely conducting beyond visual range air battles with the ‘Blue Force’. Colonel Kilian recalls, “We flew 24 sorties over the two-week exercise, and we launched every day with our two planned Gripen Ds. We were the only participants to have a 100% operational record with the scheduled aircraft.”

“In Hungary we just don’t have large numbers of aircraft to train with, but in Spring Flag we faced COMAO (combined air operations) packages of 20, 25 or 30 aircraft. The training value for us was to work with that many aircraft on our radar – and even with our limited experience we could see that the Gripen radar is fantastic. We would see the others at long ranges, we could discriminate all the individual aircraft even in tight formations and using extended modes. The jamming had almost no effect on us – and that surprised a lot of people.”

“Other aircraft couldn’t see us – not on radar, not visually – and we had no jammers of our own with us. We got one Fox 2 kill on a F-16 who turned in between our two jets but never saw the second guy and it was a perfect shot.”

“Our weapons and tactics were limited by Red Force rules, and in an exercise like this the Red Force is always supposed to die, but even without our AMRAAMs and data links we got eight or 10 kills, including a Typhoon. Often we had no AWACS or radar support of any kind, just our regular onboard sensors – but flying like that, ‘free hunting’, we got three kills in one afternoon. It was a pretty good
experience for our first time out.”

---------------------------

Gripen is one of the world's best light weight multi role combat aircraft in production.
Gripen is designed for the high demands put on flying performance, flexibility, effectiveness, survivability and availability the future air combat environment will put.
The designation JAS stands for Jakt (Fighter), Attack (Attack) and Spaning (Reconnaissance) and means every Gripen can fullfill all three mission types.
Flying properties and performance are optimised for fighter missions with high demands on speed, acceleration and turning performance. The combination of delta wing and canards gives the JAS 39 Gripen very good take off and landing performance and superb flying characteristics.
The totally integrated avionics makes it a "programmable" aircraft. With the built in flexibility and development potential the whole JAS 39 Gripen system will retain and enhance its effectiveness and potential well into the 21st century.

//air-attack

-------------------------------

Sweden has a long tradition of building excellent high-performance fighters with a distinctive look. The JAS-39 Gripen (Griffon) is built as one of the world`s first 4+ generation fighters. It remains the only 4+ generation entry in the lightweight fighter type, its performance and operational economics are both world-class.
The Gripen is an excellent aircraft by all accounts, with attractive flyaway costs and performance, and very attractive lifetime operational costs. A wide variety of international equipment has successfully been tested and integrated with the aircraft including sensors, targeting pods (the LITENING III) and an array of weapons, most recently the MBDA Meteor long-range ramjet air-air missile.
