WASHINGTON — Support is growing both in Congress and in the Pentagon to pursue a Hawaii-based ballistic missile defense radar that the Missile Defense Agency did not include in its fiscal 2021 funding request.
Previous MDA budget requests in FY19 and FY20 asked for funding for the discriminating radar as well as another somewhere else in the Pacific. The plan in FY19 was to field the Homeland Defense Radar-Hawaii, or HDR-H, by FY23, which meant military construction would have taken place beginning in FY21. Then in FY20, MDA requested $247.7 million for the radar. Lockheed Martin received an award to develop the radar in December 2018.
But in FY21, funding for both the Hawaiian radar and the Pacific radar was missing in the request. MDA Director Vice Adm. Jon Hill said in February, when the request was released, that the agency decided to hit the brakes on its plans to set up the radars in the Pacific, instead planning to take a new look at the sensor architecture in the U.S. Indo-Pacific Command region to figure out what is necessary to handle emerging threats.
Hill noted that the area is covered by a forward-deployed AN/TPY-2 radar in Hawaii as well as the deployable Sea-Based X-Band radar. Additionally, Aegis ships with their radars are mobile and can be repositioned as needed to address threats in the near term, he added.
Yet, over the summer, the Hawaiian radar gained traction in Congress via funding support in the House Appropriations Committee's defense subcommittee's version of the FY21 defense spending bill and the Senate Armed Services Committee's version of the defense policy bill.
The House subcommittee injected $133 million to pursue the homeland defense radar in Hawaii, and the SASC added in $162 million to continue HDR-H development. The SASC also included language that essentially reminded the Pentagon that HDR-H was a response to a mandate in the FY18 National Defense Authorization Act to improve coverage for the threat of ballistic missiles in Hawaii.
The HDR-H was also listed as an unfunded requirement for FY21 by Indo-Pacific Command.
The SASC also directed the MDA to provide an updated plan that accounts for delays related to finding a site in Hawaii, noting it expects the Pentagon to fund the program in subsequent budget requests.
During a presentation at the virtually held Space and Missile Defense Symposium on Aug. 4, Hill showed a slide listing focus areas for the agency in FY21. The presentation included the currently unfunded radar, third from the top of the list.
“The potential for getting a radar onto Hawaii as part of another major sensor allows us to have that launch-all-the-way-to-intercept view out in a very large ocean area in the Pacific,” Hill said.
The HDR-H is categorized as a focus area for the MDA “because if the [Defense] Department decides to move forward with HDR-H, then the HDR-H will be deployed as part of the U.S. homeland defense architecture against long-range threats,” Mark Wright, MDA spokesman, told Defense News in an Aug. 6 statement.
The missile defense architecture “must evolve with advancements of the threat,” he added. “Space sensors do not replace but complement ground-based radars by providing track custody during radar coverage gaps. Having both terrestrial radar and space sensors provides dual phenomenology to accurately track and discriminate the threat as it continues to become more complex.”

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
