Bell dévoile le 360 Invictus, un nouvel hélicoptère d’attaque et de reconnaissance pour l’US Army
PAR LAURENT LAGNEAU
Outre le renouvellement de ses véhicules blindés, confié à la « Next Generation Combat Vehicle Cross-Functional Team », l'US Army a également lancé le plan Future Vertical Lift, lequel doit lui permettre de remplacer une grande partie de ses voilures tournantes ères à l'horizon 2028/30.
En avril, dans le cadre du Future Attack Reconnaissance Aircraft [FARA], un sous-programme de ce plan, l'US Army a pré-sélectionné cinq industriels qui devront chacun présenter un prototype. Ont donc été retenus Karem Aircraft [associé à Raytheon et Northrop Grumman], Boeing, AVX Aircraft [avec L3], Sikorsky [groupe Lockheed-Martin] et Bell [filiale de Textron].
Selon les spécifications de l'US Army, ce futur hélicoptère d'attaque doit loger dans la soute d'un avion de transport C-17, voler à la vitesse de 200 noeuds, présenter une architecture modulaire, mettre en oeuvre des drones et se passer, le cas échéant, d'équipage pour certaines missions, en particulier dans les environnements fortements contestés. Et son coût devra être « abordable ».
Depuis, et alors que Boeing et Karem Aircraft sont encore discrets sur les intentions, AVX Aircraft a présenté le concept Compound Coaxial Helicopter [CCH], qui repose sur un hélicoptère doté de commandes de vol électriques, d'un rotor contrarotatif et de deux turbines. Quant à Sikorsky, il mise sur son S-97 Raider, également muni d'un rotor contrarotatif, complété par une hélice propulsive.
De son côté, le 2 octobre, soit après avoir annoncé un partenariat avec Collins Aerospace pour le système de mission et l'avionique, Bell a levé le voile sur le « 360 Invictus » [tiré du mot latin signifiant « invicible » ou du poème du même nom signé William Ernest Henley?].
Reprenant des technologies développées pour le Bell 525 Relentless, notamment au niveau du rotor, cet appareil serait en mesure de voler à une vitesse supérieure à 185 noeuds [cela dépendra de sa configuration]. Côté armement, il sera équipé d'un canon de 20 mm et pourra emporter des missiles air-sol. Son rayon d'action devrait être de l'ordre de 135 nautiques, avec la possibilité de rester 90 minutes sur zone.
« La lutte multi-domaines sera complexe et notre équipe fournit une solution hautement performante et à faible risque pour répondre en toute confiance aux exigences opérationnelles avec une flotte durable », a fait valoir Vince Tobin, le directeur des affaires militaires chez Bell.
En effet, disposant de commandes de vol électriques, le Bell 360 Invictus fera appel à des technologies déjà éprouvées ainsi qu'à quelques innovations issues de programmes civils et militaires. Procéder de la sorte permet ainsi à l'industriel d'être très compétitif en terme de coûts, l'US Army ayant fixé à 30 millions de dollars le prix unitaire de ses futurs hélicoptères d'attaque et de reconnaissance.
Les autres constructeurs qui ne l'ont pas encore fait devraient prochainement abattre leurs cartes, la prochaine phase du programme FARA devant commencer en 2020, après la sélection de deux concepts.

How 2 Space Norway satellites will help the Air Force in the Arctic
By: Nathan Strout Two Norwegian satellites will host the core components of the U.S. Air Force's next generation satellite communications system for the arctic, Northrop Grumman announced July 3. The Air Force payloads are part of the the Enhanced Polar System Recapitalization project, a program that fills the military's satellite communications need in the arctic reguib, which is not regularly covered by the Advanced Extremely High Frequency satellite system or its predecessor, the Milstar system. EPS-R will replace the Interim Polar System, which has been providing military satellite communications in the North polar region since 1998 as an adjunct to Milstar. Similar to the AEHF satellites, the EPS-R payloads will provide secure, anti-jamming communications for war fighters. The Pentagon announced the $428.8 million contract with Northrop Grumman for the Air Force EPS-R payloads in February 2018. At the time, the Pentagon noted that the payloads could be hosted on a separately procured satellite. Then, on July 3, Northrop Grumman announced it had been awarded a contract from Space Norway for two satellites capable of delivering the agency's Arctic Satellite Broadband Mission. The two Space Norway satellites will carry several payloads, including an X-Band payload for Norwegian Defense, a Ka-Band payload for Inmarsat and the two Air Force payloads. Work on the Air Force payloads was originally expected to be completed in December 2022, though Northrop Grumman now expects both satellites will launch in late 2022. https://www.c4isrnet.com/battlefield-tech/2019/07/05/how-2-space-norway-satellites-will-help-the-air-force-in-the-arctic/

U.S. Navy pays contractors $600 million held back to ensure performance
WASHINGTON (Reuters) - The U.S. Navy has paid defense contractors $600 million it had withheld to ensure contract performance, hoping the funds would shore up finances for suppliers ravaged by the coronavirus-driven economic downturn, a Navy official said on Tuesday. The move, which follows a similar action taken by the Air Force that released billions of dollars in payments, is aimed at replacing revenue vital Pentagon suppliers have lost in their non-military businesses as the spreading coronavirus has halted business activity nationwide. “We were immediately able to infuse about $600 million of funds that we had on withholds,” James Geurts, the assistant secretary of the Navy for research, development and acquisition, told reporters on a conference call. A Navy spokesperson said “for example, with the ship repair industry, withholds were reduced to one percent.” The Navy was unable to say whether a portion of the $600 million was withheld due to poor contractor performance. The Department of Defense has also accelerated contract awards as it leverages its portion of the more than $700 billion annual defense budget to help keep suppliers afloat. Geurts wrote a memo on March 24 to his staff directing them to release or reduce the withholds. It did not discuss rectifying the root causes. Government waste watch-dogs criticized the move. “This current emergency shouldn't be an excuse to avoid accountability for poor performance that predated this outbreak,” said Mandy Smithberger, of the Project On Government Oversight in Washington. Earlier this month, Geurts said he had authorized “hundreds of millions” of dollars to be paid out to top suppliers like General Dynamics (GD.N) and Huntington Ingalls Industries (HII.N) which could flow to the supply chain. Representatives from Huntington Ingalls and General Dynamics said the Navy was not withholding money from them for poor performance. While the Navy did not name any companies that received payments, industry sources have said the biggest contractors have been filtering coronavirus-related funds to their suppliers and subcontractors who, because of their smaller size, are on much shakier financial footing. The Navy's multi-layered supply chain is comprised of companies building out President Donald Trump's vision for a 350 ship here Navy. The funding will help pay salaries and ensure hard-to-replace workers are not lost to other industries or early retirement. Geurts has said the Navy is pushing money into the defense industrial base by speeding up contract payments, hastening contract awards and releasing funds withheld for poor past performance. The U.S. Air Force said it would release $882 million in payments to Boeing (BA.N) that were held back due to flaws in the KC-46 air refueling tanker. https://www.reuters.com/article/us-usa-navy-procurement/u-s-navy-pays-contractors-600-million-held-back-to-ensure-performance-idUSKCN22A33L
