US Air Force

Nous avons l'habitude en France de se plaindre ,de ne pas se contenter de ce que nous avons et surtout de remettre en cause tout.

Je vous joins un article récent que j'ai préféré laisser dans sa version originale ,article sur la flotte de l'US Air force et de son vieillissement.

WASHINGTON, Feb. 11, 2005 – Today's Air Force is a deployed force, the service chief of staff told the Senate Armed Services Committee Feb. 10.

Gen. John Jumper told the committee that the Air Force has 30,000 airmen deployed around the world.

In the U.S. Central Command area, the service has 14 bases that are still open and active. Airmen continue to patrol American skies as part of Operation Noble Eagle.

Jumper said the service continues to mature the Air Expeditionary Force concept begun in 1997. "We now have 270,000 out of 360,000 active duty members in the AEF deployment cycle," he said. "As a matter of fact, we have about a hundred people from the air staff in the Pentagon deployed today, taking advantage of their skills."

The Air Force is also helping on the ground in Iraq. There are about 2,000 airmen on convoy duty with the U.S. Army today. They are "driving trucks with the Army through some of the most dangerous regions and dealing with the [improvised explosive devices] right alongside their Army colleagues."

He said that while airmen are doing well, the operations tempo is putting stress on the force. "The Air Force is putting the full weight of its air mobility, its special operations, its close-air support, its surveillance activity … in support of our grand operations in Iraq and in Afghanistan," he said.

At the same time, aircraft based in other areas of the world help assure stability.

The Air Force reserve components are playing huge roles in the worldwide operations. "About 55 percent of our 170,000 airlift sorties and our 36,000 air refueling sorties last year -- more than half of those were flown by Air Force -- are Air National Guard and Air Force Reserve," he said.

Air Force mobility forces showed their capability during relief operations following the Dec. 26 tsunami in South Asia.

The Air Force is also looking to the future. Jumper said unmanned aerial vehicles, the FA-22 Raptor and the Joint Strike Fighter are all systems needed to maintain aerial dominance in the years to come. Developing better worldwide command and control systems and integrating information and intelligence seamlessly across the command spectrum is also part of the Air Force mission, he said.

:arrow: The Air Force has the oldest fleet aerial fleet ever. The average age of the aircraft in the service is 23 years, according to most recent statistics. Some aircraft – such as the B-52 bombers and the KC-135 tankers – average more than 40 years old. The F-15 fighter fleet – today's air superiority fighter – is more than 18 years old. The F-16 fighter fleet averages more than 12 years. Even the F-117 Stealth fighter fleet is more than 17 years old.

"The need to begin recapitalization on some of these assets to us is very important and we will continue to pursue that … as we look out toward the future," Jumper said.

Jumper said that recruiting and retention on the active duty side "is right where we want it to be." The service actually ended fiscal 2004 over its end- strength numbers. "When stop-loss came off, people did not leave at the rates that we had expected," he said.

Air Force recruiting figures are high. "We've actually shut down recruiting for the first three months of this year so that we can stabilize at the proper end strength by the end of this fiscal year," he said. "On the Air National Guard and Air Force Reserve side, right now they are about 2 percent below their targets in both the officer and enlisted." However, Jumper expects to make recruiting and retention goals in those important components with no problems.

Plusieurs dizaines des plus anciens C-130 viennent aussi d'être interdits de vol, suite à des problèmes de fatigue du métal, ce qui n'est guère surprenant étant donné l'âge de ces appareils. Je me permets de répéter ce que j'ai déjà dit ailleurs, mais je pense que le paiement des militaires professionnels laisse trop peu de moyens pour le renouvellement des matériels. Il faudra bien revenir, aux USA comme ailleurs, à une certaine forme de conscription si on veut pas voir les armées continuer à fondre comme neige au soleil jusqu'à leur disparition. Ayez une pensée émue pour la défunte Force Aérienne Belge et ce qui reste de la Royal New Zealand Air Force. :(

Une tres grosse partie des forces armees americaines sont constitues de reserviste qui peuve etre rappeles parfois plusieurs mois. Il ne s'agit pas simplement de la garde nationale, mais aussi de pilotes de bombardier recycles chez United airlines ou Pan Am pour ma part, en France, pour l'armement de certain navire comme les bateaux oceanographiques, ou de servitude, genre remorqueur et soutien, plus le gardiennage ou l'entretien de certain materiels roulant, je verrais bien ca au main de reserviste qui serait certainement heureux de faire ce genre d'activites pour ma part encore, comme reserviste, j'irais bien faire l'acceuil de nos batiments de passage en Chine, ramasser les matafs et les trainer en bordees :lol: Ou dans une possession francaise du coin ( noumea ou la reunion ou meme durant une escale ) faire un peu l'entretien des batiments de la flotte

Sous la pression du Pentagone, le groupe Lockheed Martin Corp. a dû baisser les prix des avions de transport militaire C-130J qu'il lui reste à livrer à l'US Air Force (26 exemplaires) et aux Marines (13 exemplaires). Certains scandales dans les contrats militaires, ajoutés au coût croissant de la guerre en Irak, incitent les responsables du Pentagone à se montrer beaucoup plus sourcilleux sur les prix facturés, suite aux critiques formulées par le sénateur John McCain, qui doit prochainement prendre la présidence du Comité des forces armées au Sénat.

En attendant 42 supplémentaires vont grossir les rangs.

A si notre AdA pouvait en disposer juste une dizaine ? 8)

Les Anglais en ont 5, et j'ai vu quelque part qu'ils en voulait d'autres (2?). L'Otan va en commander 4 pour les mettres à la disposition des nations qui en aurait besoin. Je crois aussi que la Hollande et la Finlande sont interressés. Oui, à quand 4 ou 5 pour la France?

Répéter ne signifie pas forcément dire la vérité... lol

De façon plus constructive, faudrait aussi voir les coûts exponentiels des programmes qui n'ont rien à voir avec les effectifs des dites armées avant de conclure sur les sur effectifs. D'ailleurs, quand on regarde les circonstances actuelles, il leur faudrait plutôt plus de personnel, notamment en Irak.

Bref, faudrait pas faire comme dans l'industrie se dire "le problème est le sureffectif" quand en fait ça vient d'ailleurs, genre le manque de produits qui marchent et des volumes de vente en bernes.

M'enfin.

Nov 8/11: At US Senate Armed Services Committee hearings on Counterfeit Electronic Parts in the DOD Supply Chain, it’s revealed that suspect electronic parts from China have been installed on a variety of military systems and subsystems, including C-27Js. This is, in part, a natural consequences of electronics life cycles vs. military life cycles, which forces the military to purchase parts from independent distributors or brokers.

On the other hand, L-3 has a non-trivial problem:

“The Committee traced the counterfeit chips to Hong Dark Electronic Trade in Shenzhen, China, who sold the parts to Global IC Trading Group… which, in turn, sold them to L-3 Displays for use in display units. More than 500 display units containing suspect parts were sold to the Air Force, the Navy, and to defense contractors, intended for installation on the C-27J, C-130J, and C-17 aircraft, as well as on the CH-46…. In total, the Committee identified nearly 30 shipments, totaling more than 28,000 electronic parts from Hong Dark to Global IC Trading Group that were subsequently sold to L-3. At least 14,000 of those parts have been identified as suspect counterfeit. Neither the Committee nor L-3 knows the status of the remaining 14,000 parts. L-3 has not yet identified what military systems they might be in.”

Le problème de composants électroniques d'origine chinoise dans les appareils américains, plus grave que prévu :

DoD’s vendors must bear the cost when they or military officials discover their products include fake electronic components, Sen. Carl Levin demanded Tuesday.

Levin, chairman of the Senate Armed Services Committee, charged out of the gate this week on a campaign to stop the flood of fake parts finding their way into military electronics.

By forcing the Raytheons and Lockheed Martins of the world to eat the costs of replacing faulty parts, the companies will have an incentive to crack down on their suppliers and ensure they’re buying only new, good-quality components, Levin said.

Although the problem of fraudulent electronic components has been broached before in media reports, Levin’s committee has been investigating them on its own and it uncovered fresh problems.

He detailed how fake microprocessors and other electronic parts had made their way into equipment aboard Navy SH-60B Seahawk helicopters; the Air Force’s C-27J Spartan cargo plane; and the Navy’s new P-8 Poseidon anti-submarine patrol plane. Plus a committee witness described buying fake voltage regulators that are used in Air Force C-130s; Navy F/A-18E Super Hornets; the Marines’ MV-22 Osprey; and Navy Los Angeles-class attack submarines.

But everyone involved acknowledged there would be no simple solution to this problem. Ralph DeNiro, vice president of L-3 Communications, said one major problem is the age of many of the military’s ships, vehicles and aircraft, which, in some cases, need parts no longer made by their original manufacturers. That means the services must broaden the base of third-party companies from which they buy replacements, increasing the risks of fakes.

Tuesday’s hearing represented the dark side of DoD’s acceptance of a “globally sourced” supply chain: Chinese officials would not permit Senate investigators to visit the counterfeit chip shops of Shenzhen, Levin said, and they were taking no action to crack down on them. So although DoD and Congress can try to throw up better screens to try to filter out the bad components in its supply chain, they apparently can do nothing about the source.

Lawmakers and witnesses made it sound as though the counterfeit parts were just local criminal fraud with new global ramifications, not a deliberate campaign of sabotage. But the stories Tuesday did raise more questions about the integrity of DoD’s computers and electronics. North Carolina Sen. Kay Hagan asked rhetorically how the Pentagon could be sure it wasn’t buying computer equipment it believed was secure, but which included fake or even malicious chips to help China with espionage or cyber-attacks.

Government Accountability Office investigator Richard Hillman said he believed Shenzhen’s counterfeiters were mostly “boiler room” operations, but he said he couldn’t rule out the possibility that malicious fake chips could be part of this poisoned well.

Quand est ce que l'on va comprendre que la Chine est un danger pour les forces occidentales. Ils jouent en permanence la carte de l'espionage et de la copie. Pour nos armements il vaut mieux confier la fabrication d'appareils sensible a nos industries. Sous couvert de faire du commerce ils piratent tout. D'ailleurs ils on déja laminé notre industrie et un peut celle des USA et on continue comme ci de rien n'était a leur faire confiance, la dernière en date avec l'aide qu'ils veulent apporter a l'Europe, ce serait une erreur stratégique monumentale.

Les USA travail sur un missile de croisière furtif avec une charge à énergie dirigé à haute puissance à base de micro ondes.

Le concept pourrait être appliqué à des drones furtifs capables d’effectuer plusieurs « tirs ».

question sur le NGM :

j'imagine qu'ils ont pensé à un mode de tir à l'image du "Home On Jam" qui permettrait de guider le missile sur un avion ennemi à partir de ses émissions radar ? Ca fait une bonne alternative passive au guidage infrarouge, j'aime bien l'idée
