  Navy Buys Tech that Can Land F-35s on Carriers with Pinpoint Accuracy

  By Hope Hodge Seck When the Navy's F-35C Joint Strike Fighter embarks on its first carrier deployment in 2021, it's expected to take with it a pinpoint-accurate landing system that purports to make the terror of night approaches and high sea-state traps all but a thing of the past. Raytheon announced this week that the Navy awarded a $234.6 million contract for a low-rate initial production of 23 of its Joint Precision Approach and Landing Systems, or JPALS -- enough to outfit every carrier and L-class amphibious assault ship with the technology. The contract also will include retrofitting three earlier systems that had been installed, a Raytheon executive said. Delivering to the Navy will start late next year, and installation will begin shortly thereafter, retired Navy Rear Adm. C.J. Jaynes, Raytheon's JPALS technical executive, told Military.com this week. The work is expected to be completed by August 2023, according to a published contract announcement. The system, which uses shipboard-relative GPS to guide planes in for landings and communicates with the aircraft from the deck of the carrier up to 200 nautical miles out, is accurate within 20 centimeters, or about 8 inches, Jaynes said. "It hits the third wire every time," she said. "It's [reliable in] all-weather and all sea states, including Sea State 5 (waves of roughly 8 to 12 feet)." For Navy pilots, catching the third of four wires on tailhook landings (or the second of three wires) has historically been a game of skill and precision that becomes orders of magnitude more difficult in the dark or in low-visibility weather conditions. Marine Corps F-35B pilots, who use the aircraft's vertical-landing configuration to put it down on the smaller flight decks of amphibious ships, face the same problems. And those issues may actually be exacerbated by a number of F-35-specific issues pending resolution. The custom-made, $400,000-per-unit helmet that F-35 pilots wear -- a piece of technology that allows them to "see through" the plane via a display for better situational awareness -- features symbology that emits a green glow, interfering with pilots' vision in low-light conditions. A video that emerged in 2017 showed an F-35 pilot landing "in a fog" on the amphibious assault ship America at night, his vision obscured by the helmet display. A recent Defense News report highlighted another issue with the helmet display at night that obscures the horizon. JPALS, which has already deployed in an early-development version with F-35Bs aboard the amphibious assault ships Wasp and Essex, would decrease reliance on visibility for accurate landings. Another F-35C-installed tool, Delta Flight Path, will keep aircraft on a steady glide slope for carrier landings, reducing inputs and corrections required from pilots. Early reports from the JPALS deployments with the Marines have been extremely positive, Jaynes said. "The pilots absolutely love it. It's been 100 percent accuracy, always available, they haven't had any issues at all," she said. "We know they have not had to abort any missions due to weather or due to sea state." Raytheon is now pitching an expeditionary version of JPALS, easily transportable and designed to guide aircraft to safe landings on bare airfields. The whole system can fit in five transit cases, be transported by C-130 Hercules, and be assembled within 90 minutes, Raytheon says. The Navy's future tanker drone, the MQ-25 Stingray, will also be JPALS-equipped; Jaynes said Raytheon is in talks with the service now about selling expeditionary JPALS for the MQ-25 program for shore-based tanker landings at locations like Norfolk, Virginia, or Point Mugu, California. Meanwhile, she said, the Marine Corps is considering buying a single expeditionary JPALS system for testing in order to develop a concept of operations to employ it. But "the closest customer outside of MQ-25 is actually the U.S. Air Force," Jaynes said. "They'd be able to move their aircraft possibly every 24 to 48 hours and do island-hopping in the Pacific. We're going over to [United States Air Forces in Europe -- Air Forces Africa] in July to talk with them about the system," she said. https://www.military.com/daily-news/2019/06/21/all-navy-carriers-amphibs-get-f-35-precision-landing-system.html

  Spatial militaire : «Nous avons les moyens de nos ambitions», selon le général Friedling (CDE)

  DEFENSE Spatial militaire : «Nous avons les moyens de nos ambitions», selon le général Friedling (CDE) Dans le cadre du Paris Air Forum, le général Michel Friedling, Commandant du CDE (Commandement de l'Espace) au sein de l'armée de l'Air et de l'Espace, Emmanuel Chiva, directeur de l'Agence de l'innovation de défense, Franck Poirrier, PDG de Sodern, représentant des équipementiers au Cospace, et Philippe Gautier, président d'Hemeria, ont échangé au sujet de la stratégie spatiale de défense française. «L'espace joue un rôle essentiel et est au cœur d'une compétition sans précédent. C'est un thé'tre de confrontation avec ses enjeux propres», rappelle le général Michel Friedling. «Nous avons les moyens de nos ambitions, et nous avons déjà des résultats. Nous avons signé les premiers contrats de service pour la surveillance de l'espace. Nous avons formé nos premiers opérateurs spatiaux. Nous aurons nos premières infrastructures à Toulouse en 2023 et premier centre de commandement en 2025», relève-t-il. L'industrie travaille à mettre au point des démonstrateurs pour la capacité d'intervention en orbite, qui devraient voler dès 2023 et 2024. Sodern travaille ainsi sur des «capteurs d'intrus», qui détecteront les objets approchant des satellites Syracuse 4, basés sur sa technologie de viseurs d'étoiles, tandis que Hemeria étudie des petits satellites patrouilleurs Yoda, pour la protection rapprochée des grands satellites géostationnaires, à partir de son expérience sur le nanosatellite Angels. Franck Poirrier, PDG de Sodern, souligne : «l'industrie est là pour servir la souveraineté et c'est pour cela qu'il faut inclure la politique industrielle dans notre réflexion autour de la maîtrise de l'espace». Un «plan équipementier» a déjà été avalisé par Airbus Defence & Space, Thales Alenia Space et les trois ministères de tutelle : le ministère de l'Économie, des Finances et de la Relance, le ministère de l'Enseignement Supérieur et de la Recherche et le ministère des Armées. L'Agence de l'innovation de défense (AID) joue un rôle majeur : «Nous sommes une usine à accélérer les projets, avec un budget d'environ 1 milliard d'euros», explique Emmanuel Chiva. «Nous sommes là pour piloter et orienter l'innovation de défense, mais également pour capter dans le civil les innovations pertinentes, car le monde spatial est éminemment dual».

  Cost Isn’t Everything. Pentagon Should Judge Contractors on Cybersecurity, Report Says

  Security would be ‘fourth pillar' in weapons purchase decisions The Pentagon should take into account the cybersecurity capabilities of defense contractors in addition to cost and performance measures when awarding contracts, a U.S. government-funded think tank recommended in a report published Monday. Through its buying process, the Pentagon “can influence and shape the conduct of its suppliers,” the Mitre Corp. said in a report titled “Deliver Uncompromised: A Strategy for Supply Chain Security and Resilience in Response to the Changing Character of War.” The Defense Department “can define requirements to incorporate new security measures, reward superior security measures in the source selection process, include contract terms that impose security obligations, and use contractual oversight to monitor contractor accomplishments,” the report said. The Pentagon must consider new measures because the very nature of war is changing, the Mitre report said. Adversaries no longer have to engage the United States in direct conflict using weapons but can respond to American military strikes “through blended operations that take place through supply chain, cyber domain, and human elements,” the report noted. The report recommends that security be made a “primary metric” in Pentagon weapons purchase and sustainment decisions and that the Defense Department increase awareness of risks associated with its supply chains. It also calls for a National Supply Chain Intelligence Center that would include officials from the FBI, Homeland Security, the Pentagon and intelligence agencies to track risks and advise agencies. When choosing current or new contractors, in addition to considering cost, performance and schedule, the Pentagon must also make security a so-called “fourth pillar,” the report said. Contractors should be continuously monitored and assessed for the degree of risk they pose, the report said. In addition to measuring a contractor's ongoing performance on a contract, an independent, federally-funded research agency could develop a risk rating similar to credit ratings done by agencies like Moody's, the report said. Mitre is a federally-funded research and development center. The Pentagon did not respond to an email seeking comment on the report. The report and its recommendations come as U.S. intelligence officials have become increasingly alarmed at potential cybersecurity risks that may be embedded in vast computer networks and systems that power government agencies as well as weapon systems. Last year the Trump administration banned federal agencies from using a popular anti-virus software made by Kaspersky Labs, which was alleged to have close ties with Russian intelligence services.
