Shipyard suspends welding on future carrier John F. Kennedy after small fire

By:

WASHINGTON — A small fire aboard the U.S. Navy's next Ford-class carrier John F. Kennedy has prompted builder Newport News Shipbuilding to shut down all welding this week as the shipyard investigates, according to a statement from Huntington Ingalls Industries, its parent company.

The fire broke out around 10:15 a.m. on Monday and was quickly extinguished by emergency crews, the statement read, resulting in no injuries.

Newport News Shipbuilding is investigating the cause of this incident,” the statement from HII spokesman Duane Bourne read. “There are no known cost or schedule impacts at this time.

“Newport News Shipbuilding secured all hot work on CVN 79 while the cause of the fire is being investigated and a yard-wide stand down was conducted for fire safety. The Navy and Newport News Shipbuilding will restore hot work on CVN 79 once the investigation is complete and any necessary corrective actions are in place.”

Fire safety has been an area of intense focus for the ship repair and shipbuilding industry since last week's fire on the amphibious assault ship Bonhomme Richard. The fire damaged 11 of 14 decks and gutted the ship's island superstructure, according to a letter from the chief of naval operations obtained by Defense News.

    DARPA, BAE to develop AI for interpreting radio-frequency signals

    By Stephen Carlson Nov. 27 (UPI) -- BAE Systems has been selected by the U.S. Defense Advanced Research Projects Agency to develop machine learning algorithms to decipher radio frequency signals for protection against enemy hacking and jamming attempts. DARPA is awarding BAE $9.2 million for machine learning algorithm development, the company announced on Tuesday, which will build off of adaptive technology that has already been applied to face- and voice-recognition systems and drones operating autonomously for RF signal processing. "The inability to uniquely identify signals in an environment creates operational risk due to the lack of situational awareness, inability to target threats, and vulnerability of communications to malicious attack," Dr. John Hogan, product line director of BAE Systems Sensor Processing and Exploitation division, said in a press release. "Our goal for the RFMLS program is to create algorithms that will enable a whole new level of understanding of the RF spectrum so users can identify and react to any signals that could be putting them in harm's way," Hogan said. Under the Phase 1 contract, BAE will develop the RFMLS as part of its artificial intelligence efforts utilizing technology from DARPA's Communications Under Extreme RF Spectrum Conditions and Adaptive Radar Countermeasures programs. BAE Systems is already working on DARPA's machine learning and artificial intelligence research in RF called the Spectrum Collaboration Challenge. SCC is meant to help alleviate scarcities in available RF spectrum, which would dovetail with work being performed on RFMLS by identifying spectrum that could evade enemy jamming. https://www.upi.com/Defense-News/2018/11/27/DARPA-BAE-to-develop-AI-for-interpreting-radio-frequency-signals/2371543335188/

  • La Belgique a survolé l'offre de Dassault pour le remplacement des F-16

    La Belgique a survolé l'offre de Dassault pour le remplacement des F-16

    Olivier Gosset L'offre française de partenariat stratégique n'a jamais été étudiée dans le détail. La version complète n'a d'ailleurs pas été déposée auprès des autorités du pays. La proposition de partenariat stratégique mise sur la table par Paris pour le remplacement des F-16 n'a jusqu'ici pas été examinée en détail par la Belgique, dont les autorités ne sont même pas en possession de l'offre complète, a-t-on appris d'une source proche du dossier. La France a décidé de ne pas participer à l'appel d'offres (Request for Government Proposal ou RfGP) lancé en mars 2017 par la Belgique pour l'achat de 34 chasseurs-bombardiers de nouvelle génération. S'engageant dans une autre voie, Paris a fait parvenir le 6 septembre 2017 au cabinet du ministre belge de la Défense, Steven Vandeput, une lettre proposant un "partenariat approfondi et structurant" fondé sur l'avion de combat Rafale. Une coopération allant bien au-delà de la seule fourniture d'avions de combat, selon les responsables français. La proposition française est restée cantonnée au niveau du cabinet de la Défense. Quelques éléments de cette offre ont filtré, principalement en ce qui concerne les retombées industrielles potentielles si la Belgique achète le Rafale. Des retours économiques que la France chiffre à 20 milliards d'euros sur 20 ans. Ensuite, plus rien! Du moins jusqu'au 15 mai dernier, lorsqu'une délégation de membres du cabinet de la ministre française des Armées, Florence Parly, s'est rendue à Bruxelles – pour la première fois en huit mois – dans le but d'expliciter auprès de leurs homologues belges l'offre française. Mais la proposition n'a pas été réellement scrutée à la loupe ni examinée sous tous les angles, puisque le document complet, qui fait plus de 3.000 pages, n'a jamais été formellement déposé en Belgique. À l'exception de la Défense, aucun cabinet belge n'a été autorisé à recevoir des représentants de l'Hexagone, et encore moins à réceptionner le volumineux dossier. Que ce soit au niveau du Premier ministre ou des Affaires étrangères. Aucun contact, même informel, ne semble avoir eu lieu non plus avec le SPF Économie ou le cabinet qui le chapeaute. Bref, la proposition française – ou du moins son résumé – est restée cantonnée au niveau du cabinet de la Défense qui, de son côté il est vrai, était tenu de travailler dans le seul cadre de l'appel d'offres en l'absence de décision politique du gouvernement remettant cette procédure en cause. Rien de nouveau? Dans ces conditions, il n'est pas étonnant que ce même cabinet ait toujours jugé non pertinente l'offre française. Ou qu'il ait indiqué n'avoir "rien entendu de nouveau" lors de la visite des émissaires français il y a quelques semaines. Que les experts militaires de l'équipe Accap, chargée d'évaluer les deux offres finales considérées comme juridiquement valables, n'aient pas pris en compte la proposition française, rien de plus normal. Pour rappel, les deux candidats qui ont remis des offres en bonne et due forme sont les Etats-Unis avec le F-35 Lightning II de Lockheed Martin et l'Eurofighter Typhoon du consortium européen éponyme. Le rapport de ces experts se trouve désormais sur le bureau de leur ministre, qui doit le transmettre au kern. Par contre, que le contenu du partenariat français n'ait jamais été examiné de près à un autre niveau en l'absence de tout engagement, voilà qui a de quoi surprendre. D'abord parce qu'il contient visiblement des éléments intéressants, comme une éventuelle participation au programme de Système de combat aérien du futur (Scaf) franco-allemand, ou encore, selon nos informations, une période très courte (sur moins de trois ans) pour la livraison des 34 appareils, quel que soit le moment où le contrat serait signé. Par ailleurs, le gouvernement belge serait bien avisé de garder plusieurs fers au feu. Parce que le résultat de l'appel d'offres risque de se heurter à des obstacles géopolitiques imprévus. Il ne va pas être très aisé en effet de justifier l'éventuelle acquisition d'appareils américains alors que l'administration Trump a déclaré une guerre commerciale au Vieux continent et que Paris et Berlin tentent de relancer l'Europe de la défense. https://www.lecho.be/entreprises/defense-aeronautique/la-belgique-a-survole-l-offre-de-dassault-pour-le-remplacement-des-f-16/10021780.html

  • Fewer airmen, fewer bombs and delayed F-15s: Goldfein outlines effects of continuing resolution

    Fewer airmen, fewer bombs and delayed F-15s: Goldfein outlines effects of continuing resolution

    By: Stephen Losey With Congress flailing in its attempt to pass a budget and the prospect of a lengthy continuing resolution growing, Air Force Chief of Staff Gen. Dave Goldfein on Wednesday outlined how bad that would be. A year-long CR, funding the Air Force at fiscal 2019 levels, would cost the service the $11.8 billion increase called for in President Trump's proposed fiscal 2020 budget, Goldfein said at a breakfast hosted by the Air Force Association in Washington. “It's truly damaging for all the services, and certainly the United States Air Force,” Goldfein said. Even if a CR only lasts for six months, the effects would be significant, he said. The Air Force would lose $1.1 billion that would go to Boeing's development and production of new F-15EX fighters, postponing their acquisition and driving up prices, according to a fact sheet Goldfein distributed. It would also force the Air Force to keep flying F-15Cs for longer than it expected, resulting in further cost increases due to the extensive maintenance needed to keep the aging fighters, plagued by structural health issues, in the air. A six-month CR would also hit the Air Force's effort to re-arm. It would reduce munitions procurement by 1,000 tailkits to convert unguided bombs into guided Joint Direct Attack Munitions, as well as cut 99 Sidewinder air-to-air missiles and 665 Small Diameter Bomb II munitions. And that CR would cost the Air Force $188 million intended for improvements to almost one-third of its F-35 fleet. But a year-long CR would be even worse, Goldfein said, hitting airmen directly and limiting the planned 3.1 percent pay raise for troops. It would also scuttle the Air Force's plans to grow its total force end strength by 4,400, he said, which would hurt its efforts to grow vital — and undermanned — career fields such as operations, maintenance, space, cyber, and intelligence, surveillance and reconnaissance. Efforts to fix the pilot shortfall would take a hit, cutting $123 million from undergraduate flight training, Goldfein said. This would mean contractor instructor pilots would be reduced, a new maintenance training center's opening would be delayed, and trainer fleet maintenance would be delayed. A CR for all of fiscal 2020 would also delay the procurement of the GPS IIIF space vehicle to replace a satellite that has now been orbiting for twice as long as it was designed, which would place the Air Force in a contract breach. It would withhold $466 million in facility sustainment, restoration and modernization funds, as well as Defense Department emergency funding, slowing the efforts to recover from natural disasters at Tyndall and Offutt Air Force bases. In all, a six-month CR would delay the start of 26 new programs, 7 production increases, and eight military construction projects. A year-long resolution would prevent 88 new starts, 14 production increases and 41 military construction projects. F-22 sensor upgrades would also be delayed if a budget is not passed, the Air Force said. But as rocky as the 2020 budget process may be, Goldfein sees even darker days to come. “If you look at the projections of funding in the years ahead, many believe that [2021] may very well be the last really good year of funding," Goldfein said. “It may not be true. But it may go flat after that, or it may start coming down. And so, how do you achieve irreversible momentum if you have one good year left of reasonable resources before a potential downturn?” https://www.airforcetimes.com/news/your-air-force/2019/11/06/fewer-airmen-fewer-bombs-and-delayed-f-15s-goldfein-outlines-effects-of-continuing-resolution/
