    Le Royaume-Uni se positionne pour 26 F-35B supplémentaires

    Le ministre d'Etat pour les acquisitions de Défense britannique, Jeremy Quin, avait annoncé, en décembre 2021, la volonté du gouvernement d'augmenter sa flotte d'avions de combat F-35. Le Maréchal de l'Air, Richard Knighton, a répondu dans une question écrite au parlement que 26 F-35B, dans la version STOVL (décollage court et atterrissage vertical), allaient être ajoutés, menant la flotte totale de F-35B anglais à 74 avions. La commande initiale britannique portait sur 48 exemplaires (ils ne seront plus que 47 après l'accident d'un exemplaire au décollage depuis le porte-aéronefs HMS Queen Elizabeth en janvier dernier) et le Royaume-Uni en aligne aujourd'hui 23. Des discussions seraient en cours avec Lockheed Martin pour le financement, alors que des fonds ont été débloqués pour ce futur achat mais aussi pour les infrastructures, l'entretien et les personnels associés. Sur les 74 appareils, une partie sera utilisée dans des unités de conversion opérationnelle afin d'entrainer les futurs pilotes anglais et une autre partie sera aussi immobilisée pour des entretiens. En ce qui concerne les 64 autres avions pour atteindre la flotte de 138 F-35B, « prévue » en 2006, ils sont toujours envisageables d'après le Maréchal de l'Air, mais il insiste sur le fait qu'une décision définitive sera prise au milieu de la décennie. Le délai s'explique par la volonté anglaise d'avancer sur le Futur Combat Air System et de choisir ensuite le nombre définitif de F-35B au sein de la Royal Air Force et de la Fleet Air Arm.

    Navy Awards Contract for P-8A Poseidon Protection

    1/20/2021 By Mandy Mayfield The Navy recently awarded BAE systems a $4 million contract for a “quick turnaround” demonstration of a new radio frequency countermeasures system for the P-8A Poseidon maritime patrol aircraft, the company announced in January. “Its primary mission is twofold. First, it's to prevent an enemy radar from locking” onto U.S. aircraft, said Don Davidson, director of the advanced compact electronic warfare solutions product line at BAE Systems. However, “if they do get a radar lock and fire a missile, its ultimate purpose is to seduce the missile away from the platform.” The system will be pod-mounted and include a small form factor jammer, a high-powered amplifier and BAE's AN/ALE-55 fiber-optic towed decoy. The decoy has been used on board other Navy aircraft such as the F/A-18E/F Super Hornet. “Right now on the P-8A, they don't have any of the equipment required to support a self-protection system,” Davidson said in an interview. “We had to put all that equipment within a pod that can be mounted on the aircraft without requiring anything on the aircraft itself.” The company will design, build and integrate the systems at its Nashua, New Hampshire, facility. Following the integration, they will be tested for two months in early 2021 on the P-8A. “This need for speed is even more prevalent today than it has been in years past,” Davidson said. The Navy issued a white paper identifying concerns about emerging threats with regard to surface-to-air missiles and asked for a self-protection capability to be delivered quickly, he noted. “Since we do this for a living, we had a lot of products and capabilities that we had developed for other applications that we were able to leverage,” he said. “We could take these existing capabilities, integrate them together — they're small enough to fit in this pod — and we could bring this capability to bear in what has essentially been five months.” The completed pod was slated to be delivered at the end of January, he said. https://www.nationaldefensemagazine.org/articles/2021/1/20/navy-awards-contract-for-p-8a-poseidon-protection

  • Israelis To Boost F-35 Fleet’s Electronic Warfare

    Israelis To Boost F-35 Fleet’s Electronic Warfare

    By ARIE EGOZIon June 15, 2020 at 1:02 PM TEL AVIV: The Israeli air force's F-35 special test aircraft is set to arrive in Israel, suitably enough, on the Fourth of July, along with three more Joint Strike Fighters. The arrival will start a planned process of upgrading the IAF's F-35 aimed at making them the main target supplier for the Israeli defense forces. In November another three are scheduled to arrive, bringing the IAF's total to 27 out of the 50 in the current contract. The special test aircraft was officially delivered to the IAF a year ago and some new systems developed by Israel have been installed. But the most sensitive systems will be installed only after the aircraft lands in Israel. Currently, the IAF operates 20 F-35 (Adir) and uses them in combat. One of the key capabilities of the F-35 is its capability to absorb electronic signals from radars and air defense systems and to quickly classify them, geolocate them, and display them to the pilot. Then the aircraft can distribute that data to other combatants. The critical data is collected by the aircraft's passive antennas embedded in the F-35's edges. They feed the signals information to the jet's computers. Using interferometers, the slightest time delay between when a signal hits one antenna compared to another, azimuth and range can be defined and target-quality coordinates created on where the threatening radio frequency emission is coming from. The already very advanced ELINT system of the F-35 is going to be further upgraded by the IAF, working with Israel's defense companies. Since the stealth fighter aircraft first arrived in Israel, some locally-made systems have been partially tested in different scenarios, but the test aircraft will allow these new systems to be put completely through their paces. The test aircraft will enable each of the Israeli F-35s to function as a “Target Generator” for all Israeli ground and naval forces thanks to what some have described as an Israeli-built command-and-control system. The Israeli companies that are developing systems for the IAF's F-35's are reluctant to provide details about the systems under development. Eitan Ben Eliyahu, former commander of the IAF, told Breaking Defense that the F-35 will bring two main capabilities to the Israeli air force's existing ones: “The stealth of course is the obvious one and it is crucial in an area where different forces deploy advanced anti-aircraft systems. “The second capability is the one that allows this aircraft to receive and distribute all kinds of combat data from a long list of sensors. This,” Ben Eliyahu said, “is very important for an air force that is performing combat missions almost on a daily basis.” https://breakingdefense.com/2020/06/israelis-to-boost-f-35-fleets-electronic-warfare
