Les JSTAR ne seront pas remplacé par des drones de si tot !

The Senate Armed Services Committee wants the Air Force to buy new engines for its fleet of E-8C Joint Surveillance-Target Attack System aircraft, it said this week, based on the notion that the service can spend the money and get the benefit before it would be able to field a new unmanned aircraft that could take JSTARS’ mission. The 17 JSTARS birds need the upgrade, but the Air Force has held off as it has investigated its potential UAV options.  JSTARS is a big, flying sensor that does for ground forces what the E-3 Sentry AWACS does in the air — provides a big tactical picture of who’s out there, what they’re doing, and how commanders might best act in response.

Senators said in a committee report that whether or not the Air Force ultimately replaces the human-piloted aircraft with a UAV, it doesn’t think that’ll happen soon enough to make it worth waiting any longer to upgrade the engines of the JSTARS fleet:

    The Air Force decided to delay the re-engining program pending a study of overall ground moving target indicator (GMTI) requirements. Regardless of what that study concludes, however, the committee believes that re-engining the JSTARS fleet makes sense. Re-engining would lead to improvements in mission capability and safety of flight margins. If, as indicated by the Air Force, re-engining would actually pay back the investment costs in savings in operating and support costs, it would make economic sense as well. Unless the Defense Department were to decide that it can afford to divest itself of the broad area GMTI capability before 2018, the investment would be worth it.

    The committee believes that the JSTARS system and the broad area GMTI capability it provides will have an important place in the future force structure. However, even if the Air Force study were to conclude that some new system or combination of systems would provide better broad area GMTI for the future, it is hard to imagine that another alternative would actually begin complete fielding of a JSTARS replacement capability before the re-engining pays for itself. The committee believes the Air Force should move expeditiously to complete that review and define its GMTI path forward.

That “combination of systems” phrase is telling — it’s possible that instead of replacing JSTARS with a big new UAV to accommodate a similar-sized radar, the service could try to field several smaller aircraft, all networked together, to achieve the same effect.

Formidable, non?

Un pays où une assemblée parlementaire encourage l'armée à investir et à dépenser plus...  :P

L'avion  Global Express XRS (BD-700-1A10) de Bombardier vient de recevoir la nouvelle désignation militaire E-11A de l'armée de l'air américaine, ce qui ce qui ouvre un nouveau marché à cet appareil conçu à l'origine pour desservir l'aviation civile.

L'armée de l'air américaine compte maintenant un total trois le nombre total d'avions Global Express XRS qu'elle exploite.

Cet avion Global Express XRS (BD-700-1A10) servira de plateforme de relais de signaux de communications en Asie du Sud-Est. L'avion transporte un noeud de communications aéroporté militaire (Battlefield Airborne Communications Node - BACN) de Northrop Grumman, qui permet à des systèmes de communications militaires distincts de partager des données.

L'avion Global Express XRS est conçu et certifié pour voler à des altitudes allant jusqu'à 15 545 m (51 000 pieds). Selon Bombardier, cet avion vole «plus vite, plus loin et peut accéder à des pistes plus courtes, tout en assurant des montées plus rapides que tout autre avion d'affaires de sa catégorie».

Il offrirait de plus une cabine «spacieuse» pour l'équipement et le personnel de mission, une importante capacité de production d'énergie électrique et un dégagement au sol élevé, qui facilite l'installation de capteurs.

Les premiers E-3 Sentry passent au block 40/45. Les 32 américains devraient être portés au standard à l'horizon 2016-2017. Nos 4 appareils également.

U.S. Navy Hawkeye Crew Evaluated USAF's E-8C JSTARS for Future Maritime Missions

The E-8C Joint Surveillance Target Attack Radar System, also known as JSTARS, flown by the 116th and 461st Air Control Wings, recently participated in naval exercises to enhance joint service training in a contested environment. The U.S. Navy’s Composite Training Unit Exercise tested crews’ ability to respond to a variety of threats for which the E-8C Joint STARS long range radar capability provided land and sea radar information to the Carrier Strike Group 4 based out of Norfolk, Virginia.

...

Flying on board JSTARS was Navy Lt. j.g. John Duffner, a naval flight officer with the Carrier Airborne Early Warning Squadron 126 out of Norfolk.

“The precision of the radar and the sheer size of the crew on JSTARS enables them to do more things simultaneously than we can do,” said Duffner. “It’s been a very interesting week, and I definitely know a lot more about how JSTARS works than I did before and I’ve been impressed.”

During the missions, the naval aviator received hands-on training and got to compare the E-2C Hawkeye command and control platform that he’s accustomed to with the JSTARS platform.
