  Thales : focus sur le système Syracuse IV

  DÉFENSE Thales : focus sur le système Syracuse IV L'Usine Nouvelle consacre un article détaillé au nouveau contrat conclu par la DGA avec Thales, rendu public le 18 février, concernant Syracuse IV (SYstème de RAdioCommunication Utilisant un SatellitE), le réseau qui permet d'assurer l'ensemble des communications militaires entre la France et les unités déployées sur les thé'tres d'opérations 24h/24. Dans le cadre de ce contrat, d'un montant de 354 millions d'euros, Thales fournira les 200 antennes satellitaires qui équiperont les navires, les sous-marins et les véhicules blindés de l'armée française. La nouvelle technologie de transmission hautement sécurisée de Thales, baptisée « modem 21 », est au cœur du système Syracuse IV. Ce modem permet d'offrir des communications dix fois plus rapides par rapport à la génération précédente, et donnent la possibilité de réaliser des communications simultanément avec une centaine d'utilisateurs. Elles sont prévues pour résister au brouillage, aux tentatives de déchiffrement, et s'adaptent à la mobilité des militaires sur le terrain. « Les premières stations issues de ces contrats seront livrées à partir de la fin de l'année 2022 », a précisé la DGA dans son communiqué. Plusieurs sites de Thales bénéficieront des retombées liées à cette commande : Cholet (Maine-et-Loire), Gennevilliers (Hauts-de-Seine) et Brive (Corrèze). « Cela va contribuer à sécuriser 800 emplois chez Thales et autant chez nos sous-traitants », précise Marc Darmon, directeur général adjoint en charge de l'activité des systèmes d'information et de communication sécurisés pour Thales.

  MDA and Army see successful Patriot and THAAD test after failure

  Jen Judson UPDATED — This story has been updated to include a statement from Lockheed Martin. WASHINGTON — After a failed test in February, the U.S. Missile Defense Agency and the Army successfully intercepted a target in an Oct. 1 test using a Patriot air and missile defense system as well as a Terminal High Altitude Area Defense, or THAAD, system integrated together, according to an MDA statement. In the test at White Sands Missile Range, New Mexico, the THAAD AN/TPY-2 radar detected and tracked a Black Dagger target missile and provided that information to the Patriot system. The Patriot launch system deployed a Patriot Advanced Capability-3 Missile Segment Enhancement missile and destroyed the target. In February, the AN/TPY-2 detected and tracked a Black Dagger and supplied the information to the Patriot system, but the missile missed the target “due to an interceptor software upgrade error,” according to the MDA statement. The error “has since been corrected, as demonstrated by today's successful intercept,” the statement noted. The success of the test "validates the interoperability of the Patriot and THAAD weapon systems,” MDA Director Vice Adm. Jon Hill said in the statement. “This capability is vital to the Ballistic Missile Defense System to defend against rogue threats to our homeland, deployed forces and allies.” “We're proud to support the Missile Defense Agency and U.S. Army Program Executive Office Missiles and Space to provide this vital capability within the Ballistic Missile Defense System,” Scott Arnold, Lockheed Martin vice president of integrated missile defense in the company's Missiles and Fire Control business, said in statement. Lockheed Martin manufactures the THAAD weapon system. The missile tests this year meet a congressional requirement for the Army and the MDA to test integration and interoperability of the THAAD and Patriot weapon systems annually. Last year, the first-ever test of THAAD's ability to remotely fire an interceptor was a success, a significant milestone in proving the ability to decouple launchers from radars and fire control systems. The Army's work to integrate the Patriot and THAAD systems was born out of an urgent operational need on the Korean Peninsula. The effort uses some of the principles of decoupling launchers and radars so an operator, for instance, can use a THAAD radar — which can see farther than a Raytheon-made Patriot radar — but decide to engage a Patriot interceptor depending on the threat picture. The ability to use the THAAD radar also gets more out of the Patriot Advanced Capability-3 Missile Segment Enhancement weapon fired from Patriot units, which outperforms the organic Patriot radar. In another test last year at White Sands, a Patriot Advanced Capability-3 Cost Reduction Initiative interceptor took out an air-breathing threat at a record distance. That test also showed it can be integrated into the Northrop Grumman-made Integrated Air and Missile Defense Battle Command System, which is the command-and-control system of the Army's future air and missile defense architecture. https://www.defensenews.com/land/2020/10/01/mda-and-army-see-successful-patriot-and-thaad-test-after-failure/

  Boeing’s F-18 jet may have a leg up in Germany over Eurofighter

  By: Sebastian Sprenger COLOGNE, Germany — The race between Boeing's F-18 jet and the Airbus Eurofighter Typhoon aircraft to replace Germany's Tornado fighter-bombers has tilted toward the American plane, according to a German media report. That is after German defense officials received information from the Pentagon about the time needed to certify the Eurofighter to carry nuclear weapons, according to an article in the Süddeutsche Zeitung. Getting the Eurofighter approved for that mission would take between three and five years longer than the F-18, which is considered a nuclear weapons-capable aircraft in the U.S. military, the newspaper reported. Germany has kept a subset of its approximately 80-strong Tornado fleet equipped to carry out the NATO nuclear-sharing doctrine. That means in the case of a hypothetical atomic war, German pilots would load their aircraft with U.S. nuclear bombs and drop them on their intended targets at the behest of the alliance. While Germany's nuclear mission periodically comes up as a source of controversy here, previous governments have left it untouched, portraying the largely symbolic assignment as a vital element of trans-Atlantic relations. A spokeswoman for the Defence Ministry in Berlin declined to comment on the SZ report, saying only that American and German defense officials have been in “continuous conversations” on the issue. The government is expected to announce a winner between the F-18 and the Eurofighter Typhoon early next year. In January 2019, defense officials eliminated the F-35 as a candidate, largely because picking an American plane would weaken the case for having such weapons be made by European companies in the future. Such is the case with the Future Combat Air Systems program, led by Airbus and Dassault. Airbus says if Germany chooses the Eurofighter as a Tornado replacement, it would be easier for companies on the continent to transition to an eventual development of the German-Franco-Spanish platform. The German defense minister's visit to Washington last month put the spotlight back on the prospect of an American buy, however. “We want to treat this question jointly,” Annegret Kramp-Karrenbauer told reporters in the U.S. capital on Sept. 23. She added that Germany wants a “gap-less” continuation of the Tornado's capabilities, adding that she envisions a “tight schedule” for the replacement. Airbus, meanwhile, doesn't see the need to rush. With 10 years or so left before ditching the Tornado, the reported nuclear-certification time seems to still fit into the overall replacement schedule, spokesman Florian Taitsch told Defense News. Plus, he argued, it should be expected that, when given a choice, the Trump administration with its “America First” doctrine would be keen to push American-made weapons over European ones. “For us, the situation hasn't changed,” Taitsch said. https://www.defensenews.com/global/europe/2019/10/04/boeings-f-18-may-have-a-leg-up-in-germany-over-eurofighter/
