  In Budget Squeeze, Coast Guard Set to Extend Life of Dolphin Helicopter Fleet

  By: Ben Werner ARLINGTON, Va. – The U.S. Coast Guard hopes to keep its aging fleet of short-range search and rescue helicopters flying for another dozen years while evaluating the potential of vertical lift studies from the Pentagon to fulfill future missions. The Coast Guard started flying the Aerospatiale Helicopter Corp. MH-65 Dolphin in 1984. The helicopters are used on both coasts and in Alaska. During disasters, the Coast Guard loads them into cargo planes for transport to the affected areas to assist search and rescue operations. But the fleet is nearing the end of its lifespan, and a replacement has yet to be identified, Adm. Karl Schultz, the commandant of the Coast Guard, said Friday during a briefing at the annual Military Reporters and Editors conference. “We're watching the Department of Defense very carefully with future of vertical lift,” Schultz said. “We fly a fleet of 98 of Aerospatiale Dolphin helicopters, MH-65s. There's no more of those being made, so that fleet of 98 is what we'll have there.” The Marine Corps and Army are leading the effort to develop vertical lift capabilities. The Marine Corps has used the tiltrotor MV-22 Osprey for years, and the Navy is now starting to integrate the airframe into its airwing as a replacement carrier onboard delivery aircraft for its aging fleet of 27 C-2A Greyhound turbo-prop aircraft. However, funding for the Coast Guard is tight for a force Schultz said is nation's first line of defense to protect borders, combat smuggling, ensure maritime traffic safety and keep ports open. The Coast Guard continually scrapes together resources and accepts cast-off equipment from the Department of Defense to accomplish its myriad of missions. “90 percent of the Coast Guard budget is classified as non-defense discretionary funding,” Schultz said. “We were shortsighted in the past not making some of these needs known.” A month into Fiscal Year 2019, Schultz does not have an approved budget, whereas the Department of Defense does. Congress will likely consider Coast Guard funding, which is part of the Department of Homeland Security appropriations bill, after next week's mid-term elections. So, with other priorities requiring funding, Schultz said the Coast Guard is determined to squeeze a decade of life out of the Dolphins. “We're probably looking to fly those more than 30,000 hours, so we're into what we're calling our MH-65 Echo upgrade,” Schultz said. “We're going to keep those things in the air for a while, probably into 2030.” At the same time, Schultz is preparing a gap solution, by squeezing more life out of another aging airframe, the Coast Guard's fleet of 45 MH-60 Jayhawks. Part of the Coast Guard's strategy includes refurbishing used Navy MH-60 Seahawks and keep them flying for about 20,000 more hours. “I'd like to grow the 60 fleet because there's no more 65s and we need to press in on that gap period – 2018 to early 2030 time frame,” Schultz said. “The 60s are our long-term solution, but we'll bridging that gap.” In FY 2018, the Coast Guard received $25 million sustain and expand the fleet of 45 MH-60 Jayhawk helicopters, and $20 million to upgrade the fleet of MH-65 Dolphins, according to the Coast Guard budget. Schultz said the active hurricane season spurred Congress to provide more money for airframes. To recapitalize Coast Guard equipment, Schultz said he'd like to see annual appropriations of about $2 billion for buying new systems or refurbishing used equipment. The Coast Guard requested $11.65 billion total in 2019 to cover procurement, operations, personnel and other costs. “We've lost 10 percent of our purchasing power in the past decade,” Schultz said. “We've deferred maintenance during this period.” The Coast Guard is also refurbishing its fleet of fixed-wing aircraft. Congress funded the purchase of a 15th C-130J cargo plane in the FY 2018 budget, and Schultz hopes, if approved, funding for a 16th C-130 will remain in the FY 2019 budget. He'd like the Coast Guard to have a fleet of 22 C-130J aircraft. Meanwhile, in 2014, the Coast Guard inherited a fleet of 14 C-27J Spartan cargo planes from the U.S. Air Force. The Coast Guard is in the process of preparing these medium-range twin-engine turboprop planes for search and rescue missions, but Schultz said they ran into a snag. “There's a bit of a worldwide parts shortage,” Schultz said. “We're fielding the C-27s, and the first ones are out at our air station in Sacramento.” https://news.usni.org/2018/10/29/squeezing-another-decade-out-of-dolphin-helicopters

  New F-35 Modification Facility Brings Strategic Capability to FRCE

  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
