  The F-35 Lightning II can’t fly in lightning once again

  By: Valerie Insinna WASHINGTON — The most widely used variant of the F-35 Joint Strike Fighter is currently unable to fly in thunderstorms after the discovery of damage to one of the systems it uses to protect itself from lightning, its prime contractor Lockheed Martin said Wednesday. To safely fly in conditions where lightning is present, the F-35 relies on its Onboard Inert Gas Generation System, or OBIGGS, which pumps nitrogen-enriched air into the fuel tanks to inert them. Without this system, a jet could explode if struck by lightning. However, damage to one of the tubes that distributes inert gas into the fuel tank was discovered during routine depot maintenance of an F-35A at Hill Air Force Base's Ogden Logistics Complex in Utah, Lockheed said in a statement. Lockheed temporarily paused F-35 deliveries June 2-23 as the company validated whether it was properly installing OBIGGS systems. However, “it appears this anomaly is occurring in the field after aircraft delivery,” Lockheed said in a statement. Lockheed has since delivered two F-35s, company spokesman Brett Ashworth said. Because it cannot be confirmed that the OBIGGS system would function properly if the jet was hit by lightning, the F-35 Joint Program Office has opted to institute flight restrictions. “As a safety precaution, the JPO recommended to unit commanders that they implement a lightning flight restriction for the F-35A, which restricts flying within 25 miles of lightning or thunderstorms,” Lockheed said. “We are working with the F-35 Joint Program Office (JPO) on a root cause corrective action investigation to determine next steps.” The issue only seems to affect the F-35A conventional-takeoff-and-landing variant, which is used by the U.S. Air Force and the majority of international customers. The OBIGGS design is slightly different on the F-35B short-takeoff-and-vertical-landing variant due to the aircraft's lift fan, and the problem has not been observed on F-35C carrier-takeoff-and-landing aircraft, Ashworth said. Bloomberg, which obtained a JPO memo dated June 5, reported that flawed tubes were found in 14 of the 24 “A” models inspected. The JPO did not respond immediately to a request for comment. For a plane nicknamed “Lightning II,” the F-35′s lightning protection systems have, ironically, become an embarrassing problem issue for the jet at times throughout its development. The F-35 was prohibited from flying within 25 miles of lightning in the early 2010s after the Pentagon's weapons tester discovered deficiencies with the original OBIGGs system in getting enough inert gas into the fuel tanks. Those restrictions were rescinded after the OBIGGS was redesigned in 2014. https://www.defensenews.com/air/2020/06/24/the-f-35-lightning-ii-cant-fly-in-lightning-once-again/

  The Army wants to build a better signals intelligence force

  By: Mark Pomerleau The Army's top intelligence official signed the service's new signals intelligence strategy July 16, a move that defense leaders believe leaves the Army better situated to better fight despite electronic warfare and cyber attacks. The new strategy ensures "our readiness to provide timely and relevant SIGINT-support [and meet] the commander's information needs in a large scale combat operation against a sophisticated adversary,” Lt. Gen. Scott Berrier, said July 18 during an event on Capitol Hill hosted by the Association of Old Crows. Officials say the integration of SIGINT, electronic warfare and cyber is critical from a material, organization and doctrinal perspective. “Not only will our four lines of effort improve our SIGINT corps' capabilities and relevance in the face of rapid changes in the global security environment, it will also enable our electronic warfare and cyberspace effort to meet new challenges,” Berrier said. The four initiatives in the new strategy include: - Organizing and building the Army SIGINT force, - Educating the force, - Equipping the force, and - Developing doctrine. The new strategy increases the Army's ability to collect intelligence against peer adversaries, such as China and Russia, and provides a firm foundation for successful electronic warfare and cyber operations, Berrier said. A key component of the convergence includes the new Terrestrial Layer System (TLS), a SIGINT/EW system projected to be fielded on vehicles and used by new military intelligence-electronic warfare (MI-EW) companies the Army is working to stand up. The Army wants SIGINT, electronic warfare and cyber systems on the same platforms in the air and ground domain, Maj. Gen. Robert Walters, commander of the Intelligence Center of Excellence, said at the event. These systems, Berrier said, should be able to not only sense the environment but employ some type of action such as electronic attack or cyber capability. Why converge? Officials have stressed repeatedly in the last year the need for colleagues in similar disciplines throughout the Army to stay in touch and reap the mutually beneficial equities on behalf of commanders in the field. Lt. Gen. Stephen Fogarty, the head of Army Cyber Command, said commanders shouldn't have to have something explained to them by the EW guy, the SIGINT guy and then the cyber guy. “What we decided is there's a better way, we have to pull it all together” for the commander, he said at the event. “We're going to have to work together because we all operate in the same space. And so do we really need three separate tools to plan operations in the spectrum? My argument would be no.” From an organizational perspective, the 29 series electronic warfare personnel will have deep knowledge in both cyber and electromagnetic spectrum operations. On the materiel side, especially with programs like the Terrestrial Layer System, the cyber and intel community are meeting regularly to integrate their requirements, officials said. In addition, Maj. Gen. John Morrison, commander of the Cyber Center of Excellence, told reporters in June that the Intelligence Center of Excellence is working with the Cyber Center to help ensure integrated formation and integrated capabilities. https://www.c4isrnet.com/intel-geoint/2018/07/19/the-army-wants-to-build-a-better-signals-intelligence-force/
