  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/

  Congressional commission wants more cyberwarriors for the military

  Mark Pomerleau The U.S. Cyberspace Solarium Commission, a bipartisan organization created in 2019 to develop a multipronged U.S. cyber strategy, will recommend the Department of Defense add more cyberwarriors to its forces, the group's co-chair said Jan. 7. The cyber mission force was established in 2013 and includes 133 teams and roughly 6,200 individuals from across the services that feed up to U.S. Cyber Command. These forces reached a staffing milestone known as full operational capability in May 2018, however, some on the commission believe the cyber landscape has changed so that the force needs to adapt as well. In a final report that's expected in the coming months, the solarium will recommend adding more cyberwarriors. “It's fair to say that force posture today in cyber is probably not adequate," said Rep. Mike Gallagher, R-Wisc., co-chair of the U.S. Cyberspace Solarium Commission. Gallagher spoke at an event hosted by the Council on Foreign Relations in Washington Jan. 7. Within the last two years, Cyber Command has described a philosophy called persistent engagement, which is a means of constantly contesting adversary behavior in cyberspace before it can be disruptive. Persistent engagement is viewed as a means of meeting the 2018 DoD cyberspace strategy's direction to “defend forward.” That action seeks to position U.S. cyber forces outside of U.S. networks to either take action against observed adversary behavior or warn partners domestically or internationally of impending cyber activity observed in foreign networks. It is under this new approach that Gallagher and other commission members said the Pentagon must ensure its forces are capable of meeting the burgeoning challenges from bad actors. “We need to figure out what's the right size” of the force, Mark Montgomery, executive director of the commission, said at an event in November. “In my mind, the CMF probably needs to be reassessed. It might be that the assessment [says] that the size is the right size. I find that hard to believe with the growth in adversary.” The cyber mission force is made up of about 5,000 service members out of a full staff of about 6,200, Dave Luber, Cyber Command's executive director said in November. According to a defense official, it's normal that staffing will fall below 100 percent but leaders are confident in DoD's cyber forces' readiness and ability to defend the nation. During a February 2019 hearing before the Senate Armed Services Committee, Cyber Command's leader, Gen. Paul Nakasone, said the force is the right size for the threats they currently face, but as it continues to operate and adversaries improve, it will need to grow beyond the 133 teams. However, Nakasone told a defense conference in California in December that the force has been built to execute the persistent engagement strategy. “Within U.S. Cyber Command, the National Security Agency, it's about persistent engagement; this idea that we will enable our partners with information and intelligence and we will act when authorized,” he said. “This is the way forward for us ... This is the way that we've structured our force. This is the way that we developed our doctrine. This is the way that we engage our adversaries ... this is our method upon which we look at the future and say this is how we have an impact on our adversaries.” Aside from the Cyberspace Solarium Commission, Congress now requires the Department of Defense to provide quarterly readiness briefings on the cyber mission force. In the annual defense policy bill, signed into law in December, Pentagon officials must brief members of Congress on the abilities of the force to conduct cyber operations based on capability, capacity of personnel, equipment, training and equipment condition. The secretary of defense must also establish metrics for assessing the readiness of the cyber mission force, under the provision. https://www.fifthdomain.com/dod/2020/01/07/congressional-commission-wants-more-cyberwarriors-for-the-military/
