Nah not all fighter jets look good in complete gray.
We painted F-16s complete gray once, dint look good. IAF painted Su-30 gray they dnt like much too good either.

Its like gray is made for Gripen & Gripen is made for gray.

All I am woundering is that how the hell did that pilot got the jet to a house. Look at the road. Looks like he drove to it.

Nordic countries always practice using normal roads as runways in case of war. It's this thing they had during the cold war if the Big Bear to the east was to take over their airfields.

Finnish Hornets even have deck arrestor hooks installed since they use them for landing on normal highways.
Here's a picture:

yeah many countries practice landing on highways including Pakistan. But the road where Gripen is standing is covered with Trees & it doesnt seem like a high way. Just a normal road.

The SAAB JAS-39 Gripen Details


Last revised June 1, 2002
Written by: Greg Goebel

[2] GRIPEN DETAILS


The Gripen is a true lightweight fighter by modern standards. It has 78% of the empty weight of an F-16C, and is about half the empty weight of the Viggen, the F/A-18E/F Super Hornet, or the Dassault Rafale. The Gripen's airframe features extensive use of composite components to reduce weight. The modest size reduces purchase cost to a degree and definitely reduces operating cost, makes the machine easier to handle on the ground, and gives it a lower radar signature.

The Gripen is a canard configuration aircraft, with a cropped delta wing with a sweep of 45 degrees, and all-moving canard forewings with a sweep of 45 degrees and dihedral. The wings are midbody-mounted to provide clearance for underwing stores, and each has a leading-edge flap and two trailing-edge drooping "elevons" to improve short-field performance, as well as maneuverability. There are two tiny strakes on the nose to generate vortices to improve flight control at high angles of attack.

The Gripen is powered by a Volvo Aero "RM-12" turbofan engine with afterburner. The RM-12 was developed in cooperation with General Electric and is derived from the GE F404J turbofan used on the Boeing F/A-18 Hornet. The F404J was selected due to its growth potential and reliability.

The Swedish version of the engine features a larger fan to provide more airflow and greater power; greater resistance to birdstrikes; and a Swedish-designed afterburner. The RM-12 provides 8,350 kilograms (18,400 pounds) of thrust in afterburner. 60% of the engine's components are built by GE, and shipped to Sweden where they are assembled along with the Swedish-built components.

Unlike the Viggen, the Gripen does not have a thrust reverser. The canard foreplanes can be tilted almost 90 degrees to act as airbrakes on landing. There are carbon brakes on all the wheels of the tricycle landing gear to reduce landing roll. The landing gear has an antiskid system. The two-wheel nose gear retracts backward, while the single-wheel main gear retract at a forward angle.

Swedish defense plans include a concept known as "BAS 90", which envisions dispersal of aircraft in groups of four to six to "road bases" defined around specially reinforced lengths of highway with associated dispersal areas. This scheme dictates the Gripen's short-field capabilities. 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 team 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. Flygvapnet experience shows that the Gripen requires 40% less maintenance work-hours and only half the fuel of the Viggen.

The Gripen cockpit layout contains three multifunction displays (MFD), plus a wide-angle head-up display (HUD) with a 28 by 22 degree field of view. The left MFD contains flight data and reflects HUD information; the lower MFD contains a tactical image in a "horizontal situation display" format; and the right MFD provides imagery from the radar, and potentially FLIR or an optical reconnaissance pod. Batch 1 and 2 machines use monochrome (green) MFDs.

The pilot flies the machine with an "hands on throttle and stick (HOTAS)" controls, including a center-mounted short-throw "ministick", and a throttle control that also operates as a joystick to make selections on the MFDs. The cockpit is climate-conditioned and pressurized, and fitted with a Martin-Baker Mark S10L zero-zero (zero altitude, zero speed) rocket propelled ejection seat. The Gripen is the first Swedish fighter not to use a SAAB-built ejection seat, and in fact the machine has considerable foreign content. The canopy hinges open sideways to the left.

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's Ferranti-Ericsson PS-05/A X-band pulse Doppler radar has three times the processing power of the Viggen's PS-46/A radar but only 60% of its volume and weight. The PS-05/A has all-altitude look down capability, resistance to jamming, and provides a number of operating modes, including:

air to air:
long range search and track
multiple target (up to ten) track while scan
short range, wide angle search and track
automatic gun and missile fire control


air to ground:
search and track
ground and sea target track while scan
high resolution mapping
air to surface ranging


A mission computer alerts the pilot to priority threats. The Gripen has a ring-laser inertial navigation system (INS), and a suite of electronic warfare (EW) aids. The initial EW suite was built around the CelsiusTech (now Saab Avionics) AR830 radar-warning receiver (RWR), with receiving antennas on the front and back of the wingtip missile launch rails.

The EW system controls a set of chaff-flare dispensers, all built by Saab Avionics. BOL dispensers are built into the end of the missile launch rails and have a total capacity of 160 chaff packs or flares. BOP/C dispensers are built into the fuselage, while BOP/B dispensers are built into the end of the wing pylons. The BOP/B dispenser can trail a "BO2D" towed repeater RF decoy, which can be towed at supersonic speed and programmed to operate in several different modes.

Avionics are linked by three MILSTD 1553B data buses, one for basic aircraft and flight data; one for cockpit displays and data; and one for tactical and weapons data.

The Flygvapnet was a pioneer in the development and deployment of datalinked combat systems, secretly fielding an initial version of a national defense datalink network with the SAAB 35 Draken fighter in the mid-1960s. They have continued to refine the network.

The Gripen is fitted with the "Tactical Information Datalink System (TIDLS)", which gives the fighter four high-bandwidth, two-way datalinks with a range of about 500 kilometers and very high resistance to jamming. The datalinks allow the Gripen to engage in combat using another aircraft's sensors or from targeting data provided by other defense systems. Data acquired from remote sources is fused and displayed on the fighter's main MFD. The link is fully operational when the aircraft is on the ground, allowing a pilot on standby to have high situational awareness of the battle environment.

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.

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. The aircraft's design philosophy dictated that it would generally carry guided weapons to ensure maximum combat effectiveness, given the aircraft's small size and limited warload. Possible external stores include:

Air to air missiles (AAMs). The primary AAM is the Raytheon AIM-120 AMRAAM, and the Gripen's PS-05A can guide four of these weapons simultaneously. Sweden is the only nation approved by the US to perform flight tests of AMRAAM, and Swedish AMRAAMs have minor modifications to their specifications.

Other possible AAM stores include the French Matra Mica; the British Aerospace Sky Flash, built in Sweden as the "Rb-71"; and the new Anglo-French MBDA ramjet-powered Meteor BVRAAM or German BGT IRIS-T AAM. IRIS-T is a short-range heat-seeking AAM with "off-boresight" capability. The Flygvapnet intends to obtain the IRIS-T to replace Swedish-built Sidewinders.
Antiship missiles, such as the SAAB RBS-15 turbojet-powered sea-skimming missile. A precision land attack version of the RBS-15 is now in development.
Air to surface missiles, such as the Raytheon AGM-65 Maverick, built in Sweden as the "Rb-75", as well as the "BK (BombKapsel) 90 Mjoelnir" guided gliding submunitions dispenser, also known as "DWS-39". The Mjoelnir was developed by Daimler-Benz Aerospace (now part of EADS), with the Gripen as the first intended flight platform. Of course, dumb bombs and unguided rocket pods have been qualified as well.


The Gripen's rapid turnaround time will help increase its combat effectiveness, allowing to be rapidly rearmed and sent on consecutive missions.

The two-seat JAS-39B Gripen is 67 centimeters (2 feet 2 inches) longer than the single-seat version. Fuel capacity is the same for both aircraft. There is no HUD for the back-seater in the two-seat version, though HUD and other video information can be linked into the back-seat display system. The JAS-39B has twin clamshell canopies. One of the interesting features of the machine is an airbag to protect the back seater from flying shards from a front-seat ejection. The airbag pops full in an instant, and then just as rapidly deflates to allow the back-seater to eject.

The JAS-39B is not really intended for flight training as such, since the Gripen is a very docile aircraft. Its primary purpose is tactical training, and except for the lack of a built-in cannon, it is fully combat capable.

Flight training for the Gripen is supplemented by four "Multi-Mission Trainer (MMT)" simulators built by Loral. Each MMT contains three wide-screen displays and a Gripen cockpit with a head-up display. The MMTs can be linked with dome simulators and other MMTs to provide interactive combat training.

The Flygvapnet is currently taking deliveries of Batch 2 Gripens, which feature a new Sundstrand APU, replacing the older Microturbo APU, which was too noisy and not reliable enough; a new Lockheed Martin flight control system computer, replacing a Lear-Siegler unit; a Kaiser HUD, replacing the Hughes-built HUD; and a new display processor. The Sundstrand APU will be retrofitted to Batch 1 Gripens, as well as early Batch 2 aircraft that had an interim improved Microturbo APU.

Production is now shifting to the Batch 3 machines, which feature:

An inflight refueling probe that retracts over the right engine intake.
A cockpit with new color MFDs and compatible with night vision goggles.
A new inertial navigation system with GPS, and an improved "Communication & Data Link 39 (CDL 39)" system. This is apparently in addition to the current TIDLS datalink.
An "on board oxygen generating system (OBOGS)".
More computing power and five MILSTD 1553B data buses, instead of three.
An improved "RM12UP" engine, with a "full authority digital engine control (FADEC)" and other improvements.
The improved "EWS-30" EW system, built around the new Saab Avionics "BOW-21" RWR, capable of recognizing a wider range of threats and targeting them more accurately. The EWS-30 includes an onboard, automatic active jammer, and can support improved towed decoys.


The last 20 Batch 2 aircraft will include some Batch 3 features, such as the color MFDs, CDL 39, and the five data buses. Deliveries are expected to shift from Batch 2 to Batch 3 in 2003.

The changes in Batch 3 give the new version a substantial increase in capability. They are sometimes referred to as "Super Gripens", with the single-seater Batch 3 machine sometimes informally referred to as the "JAS-39C" and the two-seater the "JAS-39D".

The Flygvapnet plans to obtain 204 Gripens by 2004, including 175 JAS-39As and 29 JAS-39Bs, for use in eight squadrons, replacing the Viggen. This represents a considerable downsizing of the air force, as in the late 1980s the country had 425 combat aircraft in 26 squadrons, and the original plan had been to obtain 350 Gripens.

i just love teh TIDLS Multi-pronged attack approach a single Grip can maintain a high-bandwidth two-way com link (500 miles apart with high resistance to Jamming) with four of its field friends and can utilize there Radars to track targets and attack with other Passive Sensing grips. this is amazing you can actually use other sensor sources like the Awacs that can provide its data to the grips and can provide ground radar station data too. this is the reason why i think Grips would be lethal when deployed with the proper infrastructure, and groups of three or four.
i love the part where each one of the grips can choose a radar frequency and collaboratively brun through a Jamm. so the more the better i guess and the part where one grip jams and the other track the other locks and fires lol gone !!!!!

U cant realy say that EF-2000 has an edge over Rafale. As Rafale was made in competetion to it, but it does have an edge over Gripen.
Armage u can say that Gripen is 4th Generation fighter while Rafale & EF-2000 r 4.5 Generation fighters. Although Gripen can battle both, I would say it is not much comparable to either.

overall i personally would put them in this order:

eurofighter 2000
Rafale
Gripen

but the pilot in the aircraft would have the last say. aftreall they are the controllers.
