  Navy Buys Tech that Can Land F-35s on Carriers with Pinpoint Accuracy

  By Hope Hodge Seck When the Navy's F-35C Joint Strike Fighter embarks on its first carrier deployment in 2021, it's expected to take with it a pinpoint-accurate landing system that purports to make the terror of night approaches and high sea-state traps all but a thing of the past. Raytheon announced this week that the Navy awarded a $234.6 million contract for a low-rate initial production of 23 of its Joint Precision Approach and Landing Systems, or JPALS -- enough to outfit every carrier and L-class amphibious assault ship with the technology. The contract also will include retrofitting three earlier systems that had been installed, a Raytheon executive said. Delivering to the Navy will start late next year, and installation will begin shortly thereafter, retired Navy Rear Adm. C.J. Jaynes, Raytheon's JPALS technical executive, told Military.com this week. The work is expected to be completed by August 2023, according to a published contract announcement. The system, which uses shipboard-relative GPS to guide planes in for landings and communicates with the aircraft from the deck of the carrier up to 200 nautical miles out, is accurate within 20 centimeters, or about 8 inches, Jaynes said. "It hits the third wire every time," she said. "It's [reliable in] all-weather and all sea states, including Sea State 5 (waves of roughly 8 to 12 feet)." For Navy pilots, catching the third of four wires on tailhook landings (or the second of three wires) has historically been a game of skill and precision that becomes orders of magnitude more difficult in the dark or in low-visibility weather conditions. Marine Corps F-35B pilots, who use the aircraft's vertical-landing configuration to put it down on the smaller flight decks of amphibious ships, face the same problems. And those issues may actually be exacerbated by a number of F-35-specific issues pending resolution. The custom-made, $400,000-per-unit helmet that F-35 pilots wear -- a piece of technology that allows them to "see through" the plane via a display for better situational awareness -- features symbology that emits a green glow, interfering with pilots' vision in low-light conditions. A video that emerged in 2017 showed an F-35 pilot landing "in a fog" on the amphibious assault ship America at night, his vision obscured by the helmet display. A recent Defense News report highlighted another issue with the helmet display at night that obscures the horizon. JPALS, which has already deployed in an early-development version with F-35Bs aboard the amphibious assault ships Wasp and Essex, would decrease reliance on visibility for accurate landings. Another F-35C-installed tool, Delta Flight Path, will keep aircraft on a steady glide slope for carrier landings, reducing inputs and corrections required from pilots. Early reports from the JPALS deployments with the Marines have been extremely positive, Jaynes said. "The pilots absolutely love it. It's been 100 percent accuracy, always available, they haven't had any issues at all," she said. "We know they have not had to abort any missions due to weather or due to sea state." Raytheon is now pitching an expeditionary version of JPALS, easily transportable and designed to guide aircraft to safe landings on bare airfields. The whole system can fit in five transit cases, be transported by C-130 Hercules, and be assembled within 90 minutes, Raytheon says. The Navy's future tanker drone, the MQ-25 Stingray, will also be JPALS-equipped; Jaynes said Raytheon is in talks with the service now about selling expeditionary JPALS for the MQ-25 program for shore-based tanker landings at locations like Norfolk, Virginia, or Point Mugu, California. Meanwhile, she said, the Marine Corps is considering buying a single expeditionary JPALS system for testing in order to develop a concept of operations to employ it. But "the closest customer outside of MQ-25 is actually the U.S. Air Force," Jaynes said. "They'd be able to move their aircraft possibly every 24 to 48 hours and do island-hopping in the Pacific. We're going over to [United States Air Forces in Europe -- Air Forces Africa] in July to talk with them about the system," she said. https://www.military.com/daily-news/2019/06/21/all-navy-carriers-amphibs-get-f-35-precision-landing-system.html

  US Army triggers start of possible ground mobility vehicle competition after long delay

  By: Jen Judson WASHINGTON — The Army seemed geared toward holding a rapid competition to buy a Ground Mobility Vehicle in 2016, but the plan was delayed without much explanation in favor of buying an interim vehicle already in use by special operations forces. Buying the GMV was a top priority following the fall 2015 release of the Army's Combat Vehicle Modernization Strategy, which called for such a vehicle in future and current operations. After a competition never materialized, however, rumors began to swirl that the Army may decide to buy more of the U.S. Special Operations Command's GMV — General Dynamics Ordnance and Tactical Systems' Flyer 72 — even after the service had spent several years prior testing a wide variety of commercial off-the-shelf options. But Congress spurred the effort in its fiscal 2018 defense policy bill, mandating the Army hold a competition and move forward with a program. The Program Executive Office Combat Support and Combat Service Support's product lead for the GMV has quietly stated on its website that the Army plans to pursue a competition for the GMV — calling it an Infantry Squad Vehicle — as a formal program of record. The office states that it is projected to enter into a production contract in fiscal 2020 to procure 2,000 vehicles, roughly a year later than originally planned. The Army took a big step forward on Sept. 24, releasing a market survey to industry, via the Federal Business Opportunities website, soliciting offerings for an Infantry Squad Vehicle. The notice states the service is looking for a vehicle that provides mobility for a nine-soldier infantry squad as well as its associated equipment to “move around the close battle area.” The vehicle should be lightweight, highly mobile and transportable “by all means” to include CH-47 Chinook cargo helicopters, UH-60 Black Hawk utility helicopters and by Low Velocity Air Drop. Responses to the solicitation are due on Oct. 26. While the Army has already bought quantities of the SOCOM vehicle for five airborne infantry brigade combat teams, other companies have continued to wait in the wings for the possibility to compete. And the pool of readily available ultralight vehicles is deep. In addition to GD's Flyer, these vehicles all participated in vehicle demonstrations at Fort Bragg, North Carolina, in 2014: Boeing-MSI Defense's Phantom Badger. Polaris Defense's air-transportable off-road combat vehicle DAGOR. Hendrick Dynamics' Commando Jeep. Vyper Adamas' Viper. Lockheed Martin's High Versatility Tactical Vehicle, which is a version of the British Army's HMT-400 Jackal. The Army launched its new-start GMV program in 2017 as planned, based off the service's new combat vehicle modernization strategy released in 2016, which called for the capability. The Army planned to reach a full-rate production decision on a vehicle by the end of FY19. But then it decided to split GMV procurement into two phases in the FY18 budget request and, in the first phase, planned to exclusively buy 295 of GD's Flyers through a previously awarded contract with U.S. Special Operations Command. The second phase would open up into a competition to build 1,700 more GMVs. Procuring the GMV vehicles from SOCOM raised the unit cost of the vehicle higher than the unit cost of ones that would have been procured through competition, according to FY18 budget documents. https://www.defensenews.com/digital-show-dailies/ausa/2018/10/09/us-army-triggers-start-of-possible-ground-mobility-vehicle-competition-after-long-delay
