    I think I can spot some difference in the size of the engine bays, the Future Gripen having the bigger one. If my eyes aren't playing tricks on me that is.

    I see it now. Right at the base of the tail, look closely and you should be able to see a bump. It gives the impression of a "fatter" engine bay.

    [SIZE="4"]Swedish Gripen fighters arrive at Eielson[/SIZE]

    7/20/2006 - EIELSON AIR FORCE BASE, Alaska (AFPN) -- The Swedish Air Force endured a long journey to participate in the Pacific Air Forces exercise Cooperative Cope Thunder for the first time.

    In a journey that would span more than five days, seven Gripen fighters left Sweden on July 13 for the multinational exercise. The first leg of their trip took them west to the Royal Air Force station at Lossiemouth, Scotland. After being refueled, the next stop was at Keflavik, Iceland.

    Two Swedish Air Force C-130 Hercules were used as transportation for ground crew, maintenance equipment and spare parts. The next day the squadron continued to Sondre Stromfjord, an airfield located at the southwest part of Greenland. After a few hours rest, the pilots took off for the next destination, Iqualuit in the northeast corner of Canada.

    The journey continued the next day, via Churchill to the Canadian air base Cold Lake. The two remaining legs before reaching Eielson Air Force Base were carried out on July 17. After a short stop at Yellowknife, Northwest Territories, Canada, the Gripen landed as planned at Eielson.

    By that time, the Swedish pilots and the 23 technicians from the ground crew had reached a significant milestone -- the distance flown from Sweden was 5,495 nautical miles.

    Lt. Col. Ken Lindberg, commanding officer for Tango Red, is proud of the Swedish team's execution of the first phase of this exercise.

    "I am very pleased that we arrived at Eielson on time according to our schedule. The personnel have done an excellent job, both in the planning phase and the execution," he said.

    "During these past five days we have been operating out of some unusual places. All the while, we were continuously changing time zones," Colonel Lindberg said.

    The colonel emphasized the importance of the Swedish Air Force participating in the exercise.

    "This is the first time we have taken the Gripen to the U.S. for an exercise and we are looking forward to be a part in this. It will give us a lot of important experiences for future deployment outside Sweden," he said.

    Cooperative Cope Thunder is designed to sharpen the combat skills of the participating aviation units. It provides training for deployed maintenance and support personnel in support of large force deployment air operations.

    [SIZE="3"]Enhanced Gripen radar performance on the agenda as PS-05/A negotiations proceed.[/SIZE]

    Ericsson Microwave Systems (Gothenburg, Sweden) is negotiating with the Swedish Defence Materiel Administration (FMV) for a fourth upgrade of the PS-05/A radar which equips Swedish Air Force (SwAF) Saab JAS 39 Gripen fighter aircraft, as well as those Gripens operated by the Czech Republic and Hungary and ordered by South Africa.

    Full development of the new Mk 4 version could be under contract by the end of 2006, company officials said on 13 June. The upgrade will primarily address improvements in the PS-05/A performance in air-to-surface modes, particularly those required for precision strike and close air support operations, said Jonas Branzell, project manager for future fighter radar technologies at Ericsson Microwave Systems. (The company is to become a part of Saab by September 2006 under a deal announced on 12 June).

    Capabilities to be added include "very high-resolution" synthetic aperture radar (SAR), enhanced ground moving-target indication/tracking (GMTI/GMTT) and automatic detection of stationary objects, he said. According to Branzell, the Mk 4 is to be fielded from 2010, so that all 100 JAS 39C/D model Gripens that the SwAF will continue to operate under current plans could have enhanced radar performance by 2011.

    Btw, what ever happened to the carrier-based version? Haven't heard/read anything about it since signatory's first post in this thread.

    July 27, 2006 - Volume XIV, Issue 30
    [SIZE="4"]Getting to grips: Gripen users' group formed[/SIZE]

    THE four nations which are either already operating the Swedish JAS 39 Gripen fighter aircraft, or have ordered the aircraft, have formed the Gripen Users' Group.

    During a meeting hosted by the Swedish Air Force Chief-of-Staff on July 18, Hungary, South Africa (which has just taken delivery of its first aircraft, and expects to be operational by 2009) and Sweden decided on constituting the group.

    The main goal is to initiate closer collaboration between the Gripen users concerning efficiency in both operational and technical aspects.

    "The current agreement is an important milestone for a mutually beneficial operation of the Gripen," Lt Col Jerker Fredholm, of the Swedish Air Force, said in a press statement.

    The next step will be to establish a memorandum of understanding among the user countries and to work on areas of operational and technical common interest.

    The agreement was made at the 45th bi-annual Farnborough International Airshow in the UK, which ran from July 17 - 23.

    Major Mats Gyllander, Communication Director for the Swedish Air Force, confirmed to The Budapest Sun that, although the Czech Republic, the fourth of the countries using the Gripen, was not present at the launch meeting, it, too, is a member of the users' group.

    ...Article Continues :

    From Jane's:

    The Mk 4 will involve both new software and hardware, the last primarily involving extra signal processing and high-frequency signal generation capacity.

    It will replace the current Mk 3 configuration of the PS-05/A, that became available in 2005, along with the E18 edition of the Gripen operational flight programme (OFP) software. (Sweden now has the E18:9 version of the OFP, the Czech Republic E18:7 and Hungary E18:3).

    The Mk 3, equipped with a new signal/data processor based on Mercury processor technology, already features certain SAR/GMTI/ GMTT capabilities as well as air-to-ground ranging and sea surface modes. For air-to-air, the Mk 3 has "full look-up look-down capability" plus multi-target track-while-scan, PTT and STT, short-range auto-acquisition and tracking and a beyond visual range (BVR) missile datalink capability for Raytheon AIM-120B (added as part of the E15 software in 2003) and MBDA Meteor air-to-air missiles. The radar targeting modes are also integrated with the Gripen's intra-flight datalink so that radar tracks are automatically shared with the other JAS 39 aircraft in the flight.

    By 2008, an interim air-to-ground update is to be fielded as part of the new E19 software release. (The first Gripen to use E19 is actually the first South African aircraft, which already has E19 fitted and was shipped from Saab to South Africa on 16 June 2006). The interim radar update is aimed at better preparing the JAS 39C/D for providing air support to the Swedish-led Nordic Battlegroup - a 2,000-strong rapid reaction force to be on standby for a crisis response operation under the EU flag during the first half of 2008.

    The Mk 4, which Branzell described as a "big step in the continued development of the PS-05/A", will be introduced as part of the next E20 software edition. The contract currently under negotiation is, for the time being, "just for the SwAF Gripen fleet" (how many aircraft will receive the upgrade package has yet to be decided) and not for the international Gripen users. "The Mk 4 radar is not in their current contracts; if the Czechs, Hungarians or South Africans want it their contracts will need to be modified," a senior Ericsson Microwave Systems executive told Jane's.

    According to the company's future fighter radar roadmap, the Mk 4 is to be further upgraded to Mk 5 standard by 2012, when an active electronically scanned array (AESA) antenna (for which a source of transmit/receive modules has yet to be identified, with European and US alternatives being considered) is to replace the current mechanically scanned antenna.

    "Our objective is to place the AESA antenna in front of the Mk 4 and to run the new system with upgraded software that is based on the experience we have been gathering in our NORA [Not Only Radar] technology demonstrator programme over the past few years."

    One of these demonstrator programmes has focused on SAR/GMTI techniques, using a PS-05/A derivative flown in a container in the back of a SwAF C-130H Hercules. "Results have included geo-positioning of targets and geo-coding of SAR images," Branzell said.

    The other demonstrator has concentrated on long-range detection and tracking of air targets in support of the future MBDA Meteor missile, he said. For this set-up, Ericsson Microwave Systems has been using an AESA antenna assembly that the Swedish company has acquired from Raytheon. The trials array comprises approximately 1,000 transmit/receive modules, Branzell said.

    The Raytheon-supplied AESA was placed in front of a monopulse radar configuration, the combination being capable of beam agility and flexible beam forming, Branzell said. "We have used both wide beams and narrow beams, the latter for long-range detection and tracking. The SwAF has supported these trials by providing a bunch of Gripens to test the radar's multi-target tracking capabilities."

    Further into the future (2015), the company envisions replacing the Mk 4's back-end with a new NORA radar system. This would be a full, multi-channel AESA system, of which the array can be subdivided into multiple sub-apertures capable of adaptive beam forming for jamming suppression and digital beam forming of multiple beams for multi-tasking.

    "NORA has to be a multifunctional sensor," Branzell said. "Tactical requirements for it include ensuring dominant battlespace awareness; air target tracking and fire-control for BVR weapons; all-weather precision ground target capability; track identification through non-co-operative target recognition [NCTR]; low probability of intercept [LPI] through a low radar cross section and flexible energy management; and electronic warfare inclusive of offensive jamming."

    By 2018, the next step would be to evolve the NORA sensor into a multifunction sensor that will combine active and passive radar, communications, electronic warfare and jamming. This future all-in-one sensor is currently known as EIRA for Ericsson Integrated RF Avionics - a designation that is likely to change however with the pending incorporation of the Gothenburg-based radar house into the Saab Group.

    PS. Remember, this is the EMS roadmap decided before the acuisition by SAAB... they might want to do something else and for instance move forward AESA development to support export sales to India etc. But I bet the tech will stay the same.

    I didn't write it.. I posted the source:

    Saab pledges Indian industrial participation if MRCA bid is successful
    Guy Anderson, Jane’s Defence Industry Editor, Farnborough*

    I don't know where he got that from. But that's journalism...

    Gripen International doesn't say Slovenia have any requirement at all in their sales prospect document (although they have mentioned Slovenia as a possible future candidate). But if it's not in this document then it's nothing really serious...

    Found this overview of the Integrated EW-suit on the 39C/D. Since I constantly have to inform people about it, here's some info

    The jets equipped with it can be identified with having a white dot on the fin pod.



    EWS39 is Saab's integrated EW system for the Gripen multi-role fighter aircraft. The system is modular with a built-in flexibility allowing the system to be configured to specific customer needs.

    The modular approach also permits later upgrades to incorporate technological advances or added functionality, allowing the system the future growth potential to deal with the ever-changing EW environment.

    The basic system consists of five Line Replaceable Units (LRUs), four Wing Tip Units (WTUs) and an Electronic Warfare Central Unit (EWCU). Basic frequency coverage for the RWR is E- to J -band. However, the RF coverage may be increased to suit specific customer needs. The system is prepared to handle PMW, LWR, decoys, dispensers for expendables, an internal jammer as well as an external jamming pod. EWS39 interacts with the Stores Management Computer (SMU) for control of the expendables.

    EWS39 communicates with other aircraft avionics via a standard 1553B bus and is designed to interact, and in most cases be controlled by the carriage aircraft's Systems Computer (SC). In the current configuration, the aircraft's SC provides EWS39 with mission data such as the threat and techniques library. In the current configuration, the SC also processes data from EWS39 for recording, display and audio purposes. The system uses an open architecture based on the VME bus standard. Application software includes functions for emitter identification, estimating emitter location, performing dynamic threat analysis and managing countermeasures.

    With all options incorporated, EWS39 will bestow the carriage aircraft with the capability to fulfil self-protection missions and escort jamming in both air-to-air and air-to-ground missions.


    Lookie lookie a white dot!
