    First Operational Evaluation Firing of ASMPA Missile

    The French air force has carried out the first operational evaluation of its new ASMPA supersonic nuclear stand-off missile seen here on the centreline pylon of a Rafale fighter. (French AF photo)
    On Tuesday, June 19, 2012, France’s strategic air force command successfully carried out the first operational evaluation launch of the integrated weapon system comprising a C135 tanker, a Rafale strike aircraft, and the ASMPA nuclear stand-off missile according to a scenario representative of a real mission.

    The crew of the fighter, belonging to the 1/91 “Gascogne” squadron, took off from Saint-Dizier air base. During five hours, the mission brought together all the important phases of flight: high altitude cruise, low altitude penetration, terrain following, in-flight refueling from tanker aircraft … The C135 tanker, belonging to the 2/91 “Bretagne” in-flight refueling squadron, provided the range extension needed for a strategic mission. After five hours of flight, the crew launched the ASMPA, which was not fitted with a nuclear warhead.

    Civil and military authorities tracked the missile’s trajectory and mission profile, which complied in every respect to the expected flight profile from the missile test center of the Directorate General of Armaments (DGA) located at Biscarrosse, in south-western France.

    This complex operation that brings together staff and resources of the Air Force, the DGA, industrial MBDA, the Atomic Energy Commission and Alternative Energies and the Navy (for the surveillance of the neighboring area, including the sea) is a success that validates the performance of this weapon system.

    By guaranteeing the technical and operational credibility of the airborne deterrent, the EFT test demonstrates the ability of this strategic resource to carry on with the nuclear deterrent mission which has been continuously provided, for nearly fifty years, by France’s strategic air forces.

    @TR1
    Austrian Typhoons feature no defensive system at all, they are just fitted with the chaff/flare dispensers and decoys can be released manually that’s about it.

    @Phaid
    Austria intended to buy some AMRAAMs for its Typhoon fleet in the past, but abandoned the plans on cost grounds only.

    Any idea why the Luftwaffe Typhoons from JG74 aren’t fitted with PIRATE?

    Because the MoD decided not to procure any on cost grounds. That decision was made back in the early 90s and the position haven’t changed. It was hoped that it would be ordered for T3 at least, but that hasn’t happened and while the pilots had a look at the system and would be happy to have it onboard, the chances doesn’t look that well qt this point in time.

    A possibly interesting claim from an unrelated article:

    According to Swiss air force Chief of Staff Lt. Gen. Marcus Gygax, the national evaluation showed that the Dassault Rafale and Typhoon would have costs per flight-hour within a few per cent of one another

    That’s true, but in most cases SAHR guided missiles have been used. You could also use IR guided BVR missiles if they are available, but that doesn’t change the targeting problem. For sure solutions will be worked out and what might be considered as stealthy today may not be stealthy any more tomorrow, literately spoken, but stealth technology will evolve as well. Right now it will still take years before other than US nations will introduce LO/VLO aircraft and the J-20 or a T-50 are even farther away than an F-35 for example. Wide proliferation is still some one to two decades or so away.

    Keep in mind that it’s still better to target with a radar as it provides a greater wealth of data with higher accuracy. A RWR will give you a bearing and a range estimate at best (plus emitter ID if the threat emitter is known to the library). An IRST may produce even more data including velocity, vector, acceleration rates. Combined this would be sufficient to fire a missile, but the radar data would be more reliable to obtain an adequate firing solution, though it’s prone to jamming, in theory at least. Mid-course-guidance is another issue which might not be resolved when you rely on IRST/RWR data only. Networking multiple platforms and sharing these RWR/IRST data could yield better and more accurate results however and possibly more quickly which is critical for a timed engagement.

    12F :

    I know and if I use the 200km “range” for Spectra , it is because the interferrometry (geolocation and ranging) used by the system doesn ‘t work well beyond 200km (dixit Dassault/Thalès) .
    A powerful ground radar can “wake up” SPECTRA well over 200km , of course .

    It’s hard to believe that the geo-location will work that well at such (200 km) distances. The angle inaccuracy causes an ever growing range error the longer the distance. Thus far I have seen a Rafale pilot claiming that SPECTRA can detect emitters up to around 200 km, not that it is geo-locating them with any higher level of precision at that range.

    The point is that the scores from the evaluation were for the second phase of the evaluation and this was centred around the proposed 2015 delivery configuration and in the case of the Gripen it was the MS21 and not the old JAS 39C/D as you suggested. Whether the MS21 configuration has further evolved ever since isn’t important here in the first place.

    So Saab had no clue what they were doing and proposed a variant they haven’t thought about? Maybe you read the leaked excerpts from the evaluation report before you shout nonsense!:rolleyes:

    They can listen to the Swiss experts that conclude SPECTRA is 6% better than the EW on the ole Gripen, with 2 decimal precision 🙂

    It wasn’t the old Gripen, but the proposed MS21 configuration with 98 upgrades! Whether it included EWS enhancements is unknown, but likely IMO. The old Gripen lacks LWS and MWS and that alone is a disadvantage, even if the rest of the suite is comparable. As Saab has developed such systems with its partners I think it’s likely that they were able to demonstrate these technologies and obtained some higher scores by that.

    @TMor
    That’s a rather stupid explanation. Do you seriously believe that the UAE AF is basing it’s requirements and concerns on base of internet rumours and news paper articles?

    @BW
    Dassault wan’t the sole European aerospace company to work on stealth technology at that time… And Typhoon’s design includes more RCS reduction features and its canards are in fact RAM treated on the leading edges, so you are wrong again.

    I somewhat tend to disagree. Multirole insists the ability to perform multiple missions that’s correct. Swing role means you are able to swing roles in flight seemlessly. Omnirole is merely am extension by cocering “all” roles. A sei grole capable aircraft might not be able to cover all roles, but different roles. Different variants of a single aircraft type don’t count as multirole per se. Multirole already implies that one aircraft type is performing different missions. Typically multirole and swingrole are more or less tied to each other these days. All mOdern combat aircraft can be employed in different roles and can swings those in flight. You can’t hope to perform all of them within a single flight and that’s first and foremost owed to payload constraints.

    @TooCool & BW
    Maybe you chaps should start to listen and think about what Opit says instead of argueing against it for the sake of defending your rather narrow minded ideas of the oh so special nature of what omnirole means and its subsequent implications. You have to understand the specific nature of the French armed forces structure and their operational requirements to understand why Rafale is designed the way it is and why the omnirole tag, while fitting, is not that special per se. You are quite ignorant towards the true nature of the concept and what it means and exaggerate for the sake of defending your favourite aircraft. Opit isn’t criticising Rafale he puts facts into a realistic perspective, something neither of you guys could claim as you are blinded by that this must be something particularly special.

    There isn’t too much known (to me) about the Rafale D pursued by the AdA in the late 1980s other than its signature requirements being more stringent. The Rafale C01 prototype featured the intakes of the proposed stealthier variant, which were abandoned for subsequent aircraft, including production models. The more relaxed signature requirements emerged after the end of the Cold War in attempt to lower costs. But I’m not aware off other features which were cancelled for that reason and I subsequently don’t know how much more stealthy the original design would have been in comparison to the eventual design. Other than that it doesn’t look like the French made many compromises following the end of the Cold War. The numbers were slashed over the years from the original 336 aircraft requirement (225 single seats and 25 twin seats for the AdA and 86 single seats for the MN) to 320 ac (139 B/95C and 86 M) in 1991, 294 ac (reduction to 60 M) to the current 286 (228 B/C possibly with an unknow split and 58 M). Temporary plans to procure between 35-40 Rafale N at the expense of an equivalent number of Ms were abandoned as was the development of a dedicated export variant dubbed Rafale MKII (AESA radar, M88-3 engines, 3000 l centre line tank and CFTs).

    Some known changes for the “definitive” F3 variant included the cancellation of DVI and HMD (Gerfaut being selected over the TopSight-E) due to cost considerations and changing priorities (funding of the RBE2AA AESA, DDM-NG, OSF-IT) and the cancellation of some weapons (AS.30L in particular), ANF (proposed but ultimately cancelled successor of the AM39 Exocet) and the Apache has not be integrated on the Rafale yet (it might be once the M2k-D is withdrawn from service). Other new weapons were developed and integrated however, the AASM in particular.
