By Heather Wilburn, Fleet Readiness Center Public Affairs MARINE CORPS AIR STATION CHERRY POINT, N.C. (NNS) -- A recently-completed facility will bring a new strategic capability to Fleet Readiness Center East (FRCE) and the F-35B Lightning aircraft line next year. When the new F-35 laser shock peening facility is fully operational in 2020, FRCE will be one of two sites in the world that will use laser technology to strengthen F-35 structural components. Construction of the $6 million facility wrapped in July, and the contractor providing the laser shock peening service will take occupancy in early spring, said Donald Jeter, portfolio manager of the F-35 aircraft line at FRCE. Under that timeline, the first F-35 aircraft inducted for laser shock peening would arrive in June to undergo the validation and verification process, and then the depot will begin work on the remainder of the F-35 fleet that requires the laser shock peening modification. “This facility is a big get for Fleet Readiness Center East,” Jeter said. “It's very exciting. Being able to perform this laser shock peening process adds a huge strategic capability to our depot. With it, we'll be able to provide a critical support element to the F-35B program and act as a force multiplier for the fleet and the warfighter.” The 16,000-square-foot facility comprises two bays, where the actual laser shock peening process will take place, and a connected area that will house the laser generator. The state-of-the-art laser shock peening process will allow FRCE to conduct heavy structure modifications that will strengthen areas of the F-35's airframe without disassembling the entire aircraft, said Matthew Crisp, the F-35 Joint Program Office site lead at FRCE. The process strengthens designs without adding additional metal or weight, which increases the aircraft's life and reduces maintenance costs. It has been used on the F-22 Raptor and in manufacturing aircraft components including engine blades, Crisp said, but has never been employed for the F-35. Now, FRCE will use the technology to help Marine Corps aircraft reach their full life limit. Aircraft maintenance professionals at FRCE will conduct prep work and some structural modification on the F-35s inducted into the depot, then turn them over to the contractor running the laser shock peening operations. The contractor will complete the process to strengthen the bulkheads and airframes, and FRCE will put the jets back together, perform all the flight test functions and get them back out to the fleet, Jeter said. The end result is aircraft that have been reinforced without adding additional weight, which would reduce the fighter's capabilities by limiting its fuel or weapons carrying capacity. Shot peening is not a new process, Crisp said, but laser shock peening is unique in that it produces a uniform result across the surface being treated. In laser shock peening, the surface of the media is first coated with an ablative layer and covered with a water tamping layer. A high-energy laser beam is fired at the metal, which creates an area of plasma on the metal's surface. The impact creates a shock wave, which travels through the metal, and compressive residual stresses remain. This compression helps improve the metal's damage tolerance, fatigue life and strength. “(Shot peening) has been done for decades,” he explained. “It's where you take a solid media, like glass beads or some kind of metal, and you hit the surface of an item – kind of like sandblasting. You just randomly throw it at the surface, and it creates all these surface dimples. What you get is a very inconsistent surface profile, because it's not controlled.” With laser shock peening, the process is very controlled, Crisp said. “They create a laser beam that's actually square, and the intensity is consistent across the entire laser beam – it's the exact same at the very edge of the beam as it is in the middle,” he said. “They come up with a grid pattern and stack the squares up right beside each other, so the entire surface of the part is completely uniform. You don't have the weak spots in between these areas that would then induce cracking later.” Jeter said he expects laser shock peening to be a main focus of the F-35 line for the next four to five years. Once the first two aircraft have undergone the validation and verification process, it will be a sprint to the finish to complete modifications on the remainder of the F-35B fleet that requires this treatment. “After that val/ver event, the aircraft will basically be nose-to-tail,” Crisp added. “We'll completely fill every aircraft stall that's here, and for the next five years, when one leaves another will come in. That's critical, because this process has to be done on every single airplane that requires it.” The workload does not include every F-35 ever produced, although it does include B and C models, and also encompasses F-35 aircraft owned by partner nations. FRCE will focus solely on the B variant, while Ogden Air Force Base in Utah will work on the F-35C models and take any F-35B overflow. After the first round of laser shock peening modifications, what comes after that is still to be determined, Crisp said. “I'm sure there will be some follow-on work,” he said. “And beyond the F-35 program, this is a little bit exciting, because this really is cutting-edge technology and we have it here at FRCE. I think maybe within the engineering community here, as people find out more about it, they may open additional discussions about how we could implement this on other aircraft lines. We might find a future capability we want to look at.” FRCE is North Carolina's largest maintenance, repair, overhaul and technical services provider, with more than 4,200 civilian, military and contract workers. Its annual revenue exceeds $720 million. The depot generates combat air power for America's Marines and Naval forces while serving as an integral part of the greater U.S. Navy; Naval Air Systems Command; and Commander, Fleet Readiness Centers. https://www.navy.mil/submit/display.asp?story_id=110618

Mark Pomerleau Members of the National Guard from New England states concluded a two-week cyber exercise that sought to test the cyber skills of guardsmen and critical infrastructure operators. Cyber Yankee 2020, which took place July 21-31 in New Hampshire, involved more than 200 National Guard members and their civilian counterparts from across New England states, along with some active-duty partners and participants from local, state and federal agencies. In its sixth year, there was less attendance than previous years due to the coronavirus pandemic, but several were able to participate remotely. “Cyber Yankee is primarily a hands-on keyboard cyber incident response exercise for National Guard soldiers and airmen in FEMA Region 1, which are the six New England states,” said Lt. Col. Woody Groton, a member of the New Hampshire National Guard and the director for Cyber Yankee, according to a Facebook post by the New Hampshire Air National Guard. Groton said in a video that the exercise is primarily focused on the electrical and water sector. The exercise is “a great training opportunity for us to work with those people who would actually own the network that we would potentially respond on and for our soldiers and airmen to get that experience and for the engineers from those various entities, they get the training in working with us,” he said. The Guard units within the various states are a critical resource to defend against cyberattacks when they overwhelm localities. “If a large-scale attack happened against a power company, water company, or any other critical department around the state, we would be able to get activated and help them mitigate the threat,” Capt. Frederick Bond, 103rd Air Control Squadron cyberspace operator and exercise Team 3 lead from the Connecticut National Guard, said in a release. “It's similar to when a storm comes and we help remove fallen trees or shovel snow from roofs to help get critical infrastructure going again.” The friendly blue team had to deal with simulated attacks from an opposing red team. Social media posts were used to simulate a real internet environment, where forces must sift through the noise and discern what information is needed to make decisions and identify threat actors. In one case, these actors defaced a public website. “We found some discrepancies including website, it looks like it may have been defaced. The team is digging into finding the source of that defacement and then making steps to correct it,” Master Sgt. Eric Lewis, a blue team member in the New Hampshire Air National Guard, said in a video. Other actions tested included protecting computer files from being stolen or manipulated. “We received intel that potential threat actors may be using a certain capability to transfer files,” said Senior Airman Stephen LaLuna, 103rd Communications Flight cyber systems operations specialist with the Connecticut National Guard. “We see the traffic that's using it, that sets off a flag on our end to look deeper into that. If we determine it is malicious, we send it up the chain with our findings and recommendations to block it.” Officials explained that one of the most critical aspects of these training events is the partnerships built between Guard units, critical infrastructure operators and government entities so that when a crisis breaks out, everyone is acquainted. “We have built enduring partnerships with state government and the critical infrastructure sector. Something that if we did have a major cyberattack against one of those, we would be ready to respond and already know each other,” Groton said.
