La Suède affirme avoir construit un avion «tueur» de chasseurs russes Sukhoi

Les avions de chasse Saab Gripen sont conçus pour «tuer» les redoutables chasseurs russes Sukhoi en combat aérien et ils possèdent une «ceinture noire» dans ce type de combat, a déclaré le commandant de l'armée de l'air suédoise.

Le chasseur suédois Gripen est fait pour détruire les Sukhoi russes et sa furtivité n'y est pour rien, a annoncé le commandant de l'armée de l'air suédoise Mats Helgesson.

«Le Gripen, en particulier le modèle E, est conçu pour tuer les Sukhoi. Nous avons une ceinture noire», a déclaré Mats Helgesson cité par Business Insider.

Selon le média, les avions de chasse russes Sukhoi ont acquis une sorte de statut légendaire en raison de leur capacité à déjouer les avions de combat américains lors de combats aériens et à réaliser des acrobaties dangereuses et agressives, mais le Gripen a peut-être déchiffré son énigme.

«Le Gripen ne peut pas porter un plus grand nombre d'armes, n'a pas de furtivité réelle et n'est pas un avion avec un véritable rayon d'action. Il n'est pas le plus rapide ni même le moins cher. Mais il dispose d'une particularité qui en fait un cauchemar pour les avions de combat russes», affirme Business Insider.

Justin Bronk, expert au Royal United Services Institute, a déclaré à Business Insider que le Gripen était au-dessus des autres en termes d'efficacité de la lutte électronique et de brouillage de radars.

«Il y a plusieurs années, les pilotes du Gripen étaient fatigués de se voir ridiculisés par les pilotes allemands de Typhoon. Ils ont alors mis en marche leurs moyens de guerre électronique et ont fait passer un sacré coup dur aux Allemands», a relaté Justin Bronk.

Selon lui, un Gripen aurait «pu apparaître sur l'aile gauche d'un Typhoon sans être détecté en utilisant sa capacité de brouillage».

«Pour vaincre les redoutables chasseurs et missiles sol-air russes, les États-Unis se sont largement tournés vers les avions furtifs. La furtivité coûte une fortune et doit être intégrée à la forme de l'avion», signale Business Insider ajoutant que si la Russie déchiffre le code de détection des avions furtifs F-35 américains, le système d'armes le plus cher de l'histoire sera perdu.

«Mais Saab a adopté pour ses avions une approche différente et moins chère pour lutter contre les chasseurs et les missiles russes en se concentrant sur l'attaque électronique, ce qui leur confère un avantage sur la furtivité, car ils peuvent faire évoluer le logiciel sans une reconstruction totale», a résumé Justin Bronk.

Le chasseur polyvalent Su-57 de cinquième génération, connu auparavant sous le nom de T-50 PAK FA, a effectué son premier vol en 2010. L'appareil est destiné à détruire des objectifs aériens, terrestres et navals. Il est également capable de déjouer les systèmes de défense aérienne existants et en développement.

En février 2018, le ministre russe de la Défense Sergueï Choïgou a révélé que deux Su-57 avaient été testés en Syrie.

Dans la conception de l'appareil, qui combine les fonctions de chasseur et d'avion d'attaque au sol, des technologies furtives et des matériaux composites sont utilisés.

Selon l'annonce du président de la Compagnie aéronautique unifiée, Youri Slioussar, la livraison du premier avion fabriqué en série pour les Forces aérospatiales russes est prévue pour 2019.

    For the Navy’s hospital ships, networking is yet another challenge

    Andrew Eversden When the Navy hospital ship Comfort deployed to Haiti in 2010 following devastating earthquakes, media organizations broadcasting in the area ate up so much satellite bandwidth that the ship had to revert to paper processes and adjust its satellite communications for some ship-to-shore messaging. While the outages weren't a widespread issue, said Sean Kelley, who served as the ship's top IT officer at the time, the problem highlighted a challenge these ships face: broadband. Now, the hospital ships Mercy and Comfort are deployed to Los Angeles and New York, respectively, and are in the national spotlight as symbols of the coronavirus pandemic relief effort. But security and IT experts say the ships' mission presents the Navy with distinct networking problems, from cybersecurity to network connection for patients. Onboard devices When disaster strikes, the Navy's hospital ships deploy in a matter of days, mobilizing with a crew of about 100-1,200 personnel. But the influx of staff also leads to an incursion of devices, all of which must be secure and require bandwidth. “You have a lot of different people going to a lot of different places that now have to be acclimated to this environment,” said Kelley, now executive vice president at Unissant, an IT and cybersecurity company. “So that's really one of the biggest challenges, is getting all those things turned on, all those things activated, making sure that they are all compliant with the latest patches and fixes, and making sure they're good.” This process can be a “nightmare,” said retired Rear Adm. Danelle Barrett, former deputy chief information officer of the Navy and cybersecurity division director. “The challenging part is always in the first couple days whenever this happens,” said Barrett, who oversaw communications and cyberspace for Operation Unified Response, the U.S. military's mission in Haiti following the 2010 earthquake. “The team is coalescing about how they want to operate, and they're getting their feet wet, getting new accounts on networks ... [getting] their logins.” Cybersecurity aboard the ships is also complex. Both ships have 1,000 beds, 12 operating rooms, blood banks, labs, medical devices and a multitude of other “internet of things” devices connected to hospital beds. According to a 2018 survey by health care IoT security company Zingbox, each bed can have as many as 10-15 IoT devices. “They have to be cyber-ready, or the mission of the Mercy is considered [degraded],” said Dean Hullings, global defense solutions strategist at Forescout, which handles Comply to Connect — a Defense Department framework created to ensure the cybersecurity of new devices — for the USNS Mercy. Ensuring connectivity For the devices to function, they need connectivity. When the ships arrived in ports in late March, technology firm CenturyLink “donated” connectivity to the Mercy, while Verizon provided connectivity to the Comfort. Former and current Navy officials told C4ISRNET that adequate broadband is the most challenging IT consideration faced by these ships. “Obviously you're going to be transferring imagery of X-rays or things like that that are more dense and require a ... higher data rate, so that bandwidth in port is important,” Barrett said. And with the introduction of patients, bandwidth needs become more complex. “The greatest communications challenge we are going to face during this deployment is the increased need for patients to communicate off the ship during their stay,” Tom Van Leunen, a spokesman for Military Sealift Command, told C4ISRNET. “Our hospital ships are designed to support official communication for the ship's crew and embarked medical community to complete their job. Adding a capability for patients to reach loved ones increases the risk of saturating the bandwidth off the ship.” Aboard both ships, the Navy doubled the bandwidth, he said, adding that Navy personnel also set up separate networks for patients' communications. While this solves one networking problem, it can also create an increased cybersecurity risk. Securing the ships Cybersecurity on the hospital ships follows the same standard practices as the rest of the Navy fleet. Since those aboard are largely Navy medical staff and personnel, they know what activities are acceptable on the network, Barrett said. “You can't just go and plug anything into that network because of potential vulnerabilities that that system may bring that could affect not just the ship, but remember, the ship is then connected to the rest of the [Department of Defense Information Network],” Barrett said. “So risk by one is shared by all.” ForeScout's Hullings said a hospital environment “epitomizes” why the Comply to Connect program is necessary. The ship has desktops, servers, routers, printers and other networks equipment, as well as mobile devices, such as tablets, that health care providers use to track patient care. “The truly unique stuff is the mission systems of the hospital, like X-ray machines, MRI machines, the beds themselves in the post-operative recovery rooms, that are all sensors. And they are all passing data. They have to be protected,” Hullings said. A spokesperson for the Navy told C4ISRNET that the ships are prepared for the cybersecurity challenges associated with their missions, but declined to address what additional cybersecurity challenges are introduced with the addition of private citizens. “These ships have routinely deployed in humanitarian assistance missions such as Pacific Partnership (USNS Mercy) and Continuing Promise (USNS Comfort) that required them to operate in partner nation ports, with foreign national patients being brought to and from the ship,” said Cmdr. Dave Benham, a spokesman for the Navy's 10th Fleet. “In all operating locations, we take appropriate precautions to keep our networks secure, and we do not discuss specific measures in order to protect operational security.” Cybersecurity on the hospital ships follow the same protocols as any other Military Sealift Command ship, said Benham. “Protecting our networks is a continuous challenge, and the overarching concern is to ensure that the right information gets to the right place at the right time with the right level of protection,” he explained. Cybersecurity aboard the hospital ships follow similar efforts to those recommendations made by the Centers for Disease Control and Prevention: Wash your hands. “It's ‘wash your hands' with your computer, too,” Barrett said. “Do good hygiene with your computer.” https://www.c4isrnet.com/it-networks/2020/04/21/for-the-navys-hospital-ships-networking-is-yet-another-challenge/

    Northrop Grumman Awarded Contract for Remote Sensing Proof of Concept

    MCLEAN, Va. – September 23, 2019 – Northrop Grumman Corporation (NYSE: NOC) has received a contract award from the California Department of Forestry and Fire Protection (CAL FIRE) for a proof of concept demonstration referred to as FireWatch. This contract will allow Northrop Grumman's Computer-Aided Dispatch (CAD) system, installed at CAL FIRE, to receive fire detection and location information from fused remote sensing data, enabling early detection so that first responders can take quicker action against fires as they emerge. “Being able to take rapid action against wildfires can prevent the loss of human life, property and infrastructure, while also preserving the environment and watersheds of California,” said Chris Williams, vice president, integrated fires and protective systems, Northrop Grumman. “FireWatch will demonstrate to CAL FIRE the value of up-to-the-minute remote sensing data to significantly expand their CAD capabilities.” The ability to share remote sensing data aided in the response to California's devastating fires in November 2018. With support from Northrop Grumman, U.S. government agencies were able to share information rapidly as fires changed course or new flare-ups emerged. This contract will formalize the delivery of these capabilities, thereby enabling CAL FIRE to respond even more proactively and decisively to the threat of wildfires. Northrop Grumman is a leading global security company providing innovative systems, products and solutions in autonomous systems, cyber, C4ISR, space, strike, and logistics and modernization to customers worldwide.
