  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 Netherlands to buy nine more F-35s for $1.1 billion

  By: Sebastian Sprenger COLOGNE, Germany – The Dutch government on Tuesday announced plans to purchase nine more of Lockheed Martin's F-35 jets, a move that would bring the country's inventory to 46. The envisioned €1 billion acquisition will “lay the foundation” for a third F-35 squadron in the Dutch air force, a plan that government officials first floated in late 2018, according to a statement posted on the defense ministry website. The additional aircraft are expected contribute to the air force's objective of having four jets available for NATO missions while also performing homeland defense operations and accounting for training requirements and maintenance downtime. Fully rounding out a third squadron would require 15 extra planes, however, alliance officials have previously told the Dutch, prompting talk in the Netherlands last year of a potentially higher number eventually. The Dutch want the F-35 to replace their legacy fleet of F-16s. Neighbor Belgium selected the fifth-generation aircraft in the fall of 2018, announcing a planned buy of 34 copies. Dick Zandee, a defense analyst at the Clingendael think tank in The Hague, told Defense News the announced acquisition of nine more F-35s enjoys “broad support” in the Dutch parliament. He said government leaders had already included the new aircraft spending in their annual report to NATO to show momentum in the country's move toward spending 2 percent of gross domestic product on the military. Government officials have told parliament that they want to give the American program office a formal notice to buy the additional jets before the end of the year, Zandee said. The Dutch want F-35s of the newest configuration, he added, which means any changes in the international delivery schedule caused by the recent Turkish expulsion from the F-35 program likely would play no role. The Trump administration has kicked Turkey out of the program over the country's purchase of the Russian S-400 air-defense system. American officials fear that co-locating the two systems could enable Russia to glean valuable intelligence about the planes simply by subjecting them to the S-400′s sensors. https://www.defensenews.com/global/europe/2019/10/08/the-netherlands-to-buy-nine-more-f-35s-for-11-billion
