    Here’s why the Valkyrie drone couldn’t translate between F-35 and F-22 jets during a recent test

    Valerie Insinna WASHINGTON — Earlier this month, the U.S. Air Force embarked on a hotly anticipated test: Could it use a semiautonomous drone, in this case a Kratos XQ-58A Valkyrie equipped with a special payload, to stealthily translate and send data between F-35 and F-22 fighter jets? Air Force leaders still think the answer is “yes,” but because of technical issues encountered during the test, proof that the concept works is still months away. During the Dec. 9 demonstration at Yuma Proving Ground in Arizona, the Valkyrie was outfitted with gatewayONE, a system capable of translating information from the F-35′s Multifunctional Advanced Data Link and the F-22′s Intra-Flight Data Link into a format that can be understood by other aircraft, all while maintaining a low probability of enemy forces intercepting that data. But “shortly after takeoff, the communications payloads lost connectivity,” leaving nine out of 18 test objectives incomplete, the Air Force said in a news release. Early feedback from the test team indicates that, during the rocket-assisted takeoff of the Valkyrie, some of the gatewayONE hardware came loose from where it was mated to the drone, said Air Force acquisition executive Will Roper. “We think we had a connector that came loose during it because the gateway itself was fine when the Valkyrie landed. So [it's] a thing we've learned from and we'll fix next time,” he told reporters Dec. 18 during a Defense Writers Group roundtable. “Next time we get out, flying in the next on-ramp, we'll probably check those soldering points more than one time.” Despite the setbacks, the Air Force still clocked in a number of wins during the exercise. Because the service had a second, land-based version of gatewayONE, it was able to use that system to pass targeting cues from an F-35 to an F-22 and exchange other data between the two aircraft. GatewayONE also pushed data that usually is confined to operations centers on the ground to the F-35 and F-22, while allowing those aircraft to send precise location data back through the translating system to the operations center. Although the Valkyrie couldn't transmit data between the F-22 and F-35, it still safety demonstrated that it could fly semiautonomously in operations with the two stealth jets for the first time ever. Aside from the inclusion of the XQ-58A, it's unclear how the Dec. 9 demonstration differs from ground tests of a similar system during the first Advanced Battle Management System on-ramp exercise in 2019. During that demo, the Air Force rigged together a number of radio systems built by F-35 and F-22 prime contractors Lockheed Martin and Northrop Grumman with antennas from Honeywell, and the aircraft flew over the test stand, exchanging data, officials said. As early as 2015, Northrop has touted its Freedom 550 radio as a translator for the F-35 and F-22, but it is unknown whether the technology is part of the gatewayONE system. The Air Force did not respond to questions from Defense News seeking more information about gatewayONE, such as a request to identify the manufacturer. During a phone call with reporters on Dec. 16, Air Force Chief Architect Preston Dunlap said the next opportunity for the service to experiment with the gatewayONE payload onboard Valkyrie is during the Advanced Battle Management System experiment slated for May 2021. Using a low-cost, expendable drone like the XQ-58 to transmit data between platforms is a contrast from the Air Force's usual approach for solving communications challenges among its assets, Dunlap said. Usually, as new data links or waveforms are developed, aircraft must be retrofitted with new radios and apertures — an expensive and time-consuming process that often leaves platforms out of the loop. “It's obvious to me that it's not a winning strategy and is a real estate problem on some of these platforms, but then it's a lost opportunity because when you have diversity of pathways, you have greater assurance,” he said. By creating a small, modular payload like gatewayONE that can be carried by a number of manned and unmanned aircraft, the Air Force will have more options for getting data into the cockpits of all of its planes. “The real big win — and we heard this from the pilots themselves — is being able to push information into their cockpits so that they have access to it in a way that is operationally relevant and useful to them,” Dunlap said. “It's not all the data they would want, but it has opened a door that's amazing. So we've got to keep pushing the technology.” The Dec. 9 test was carried out by personnel from the Air Force Research Laboratory, Air Force Life Cycle Management Center and the 46th Test Squadron from Eglin Air Force Base, Florida. https://www.c4isrnet.com/battlefield-tech/it-networks/2020/12/18/heres-why-the-valkyrie-drone-couldnt-translate-between-an-f-35-and-f-22-during-a-recent-test/

    Lockheed Martin to perform ‘unique sea trials' of F-35 for non-US customers

    Gareth Jennings The United States Department of Defense (DoD) has contracted Lockheed Martin to conduct aircraft carrier trials of its F-35 Lightning II Joint Strike Fighter (JSF) for potential international operators. The award, announced on 24 September, is part of a wider USD245.5 million developmental support contract for DoD and international operators of the F-35 that will run through to March 2022. “[Additional to the wider developmental support work], this modification provides unique sea trials on aircraft carriers for non-DoD participants,” the contract notification stated. Though no further details pertaining to the aircraft carrier trials were disclosed, they are likely to relate to the short take-off and vertical landing (STOVL) F-35B variant of the aircraft. To date, the US Marine Corps (USMC), United Kingdom Royal Navy (RN) and Royal Air Force (RAF), and Italian Navy (Marina Militare Italiana: MMI) have procured the F-35B to equip their respective amphibious assault ships and aircraft carriers, while current F-35A customers, Australia, Japan, Singapore, Spain, and South Korea, have all expressed interest in the STOVL jet's carrier capabilities over recent years, as had Turkey before it was disbarred from the wider JSF programme. Australia was reporting its interest in the F-35B for the Royal Australian Navy's (RAN's) two Canberra-class landing helicopter dock (LHD) amphibious assault ships as far back as 2014.

    Did your state receive the most defense dollars? We’ve got the numbers.

    By: Aaron Mehta WASHINGTON — California topped the list of states receiving defense dollars in 2019, a period in which overall Pentagon contracts and payroll spending in the 50 states and Washington, D.C., totaled $550.9 billion, the Department of Defense revealed Wednesday. Of that total, $403.9 billion (73 percent) were from contracts, with the remaining $146.9 billion (27 percent) tied up in DoD personnel salaries. Overall, defense spending represented 2.5 percent of the country's gross domestic product, according to a department statement accompanying the data. The numbers, released annually, are generally included in the case made by pro-defense lawmakers and Pentagon supporters for the benefits of a large defense budget. They come as defense spending is expected to be flat, with some progressives in Congress pushing President-elect Joe Biden to cut defense funding to support social programs instead. “The report compiled by the Office of Local Defense Community Cooperation can be a great tool to state and local officials,” Ellen Lord, undersecretary for acquisition and sustainment, said in a statement. “All of our work is aimed at supporting the National Defense Strategy and this report is key as we look to continue defense reform and modernization efforts.” The top 10 states are: California: $66.2 billion Virginia: $60.3 billion Texas: $54.8 billion Florida: $29.8 billion Maryland: $26.1 billion Connecticut: $19.7 billion Pennsylvania: $18.1 billion Washington: $17.8 billion Alabama: $16.0 billion Massachusetts: $15.8 billion California, Virginia and Texas historically rank among the top states in defense dollars. California is home to a significant aerospace presence, with all the major players in that sector bringing in large chunks of cash for their in-state work. Virginia's top firm was the major shipbuilder Huntington Ingalls Industries, but the state largely brought in funding for being the corporate home for many major defense firms — and for their lobbying efforts. And 41 percent of Texas' total comes from Lockheed Martin contracts; the company's Fort Worth facilities produce the F-35 Joint Strike Fighter, among other materiel. The top 10 overall contractors for the year were: Lockheed Martin: $45.6 billion Boeing: $25.7 billion Northrop Grumman: $19.5 billion General Dynamics: $18.6 billion Raytheon: $15.7 billion United Technologies: $10.3 billion BAE Systems: $7.3 billion Huntington Ingalls Industries: $6.7 billion Humana: $6.7 billion L3 Technologies: $4.9 billion https://www.defensenews.com/industry/2021/01/13/california-top-state-recipient-of-defense-dollars
