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

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.

    Japan reveals record high budget request eyeing hypersonic tech, F-35s and more

    Mike Yeo MELBOURNE, Australia — Japan is set to continue its recent trend of setting new records for its annual defense budgets, with the country continuing to cast a wary eye on China's military modernization and nuclear-armed North Korea's missile program. The latest budget request issued by Japan's Ministry of Defense is seeking $55 billion for fiscal 2021, which begins in April 2021. The amount is an 8 percent increase from the previous year, and makes it the eighth consecutive year the defense budget request to the Ministry of Finance has set a new record high. This is the first defense budget for the government of Prime Minister Yoshihide Suga, who looks set to continue his predecessor Shinzo Abe's push for Japan to bolster its international involvement in security matters. Unsurprisingly, the latest budget request includes potential funding for more Lockheed Martin F-35 Joint Strike Fighters. The ministry is seeking $308.5 million for four more F-35A conventional-takeoff-and-landing variants, and $249.8 million for two F-35B short-takeoff-and-vertical-landing versions. Japan has an eventual requirement for 105 F-35As and 42 F-35Bs, which makes it potentially the biggest operator of the F-35 outside of the United States. The F-35Bs will be operated onboard Japan's helicopter destroyer Izumo, which is being retrofitted domestically to operate the stealthy fifth-generation fighter jets. The budget request is seeking $218.6 million this fiscal year for the project, which will include thermally protecting the Izumo's flight deck from the jets' exhaust gases and reshaping of the ship's forward flight deck for operating the jets. As usual, the budget request also includes items related to Japan's air and ballistic missile defense capability. The country is seeking $370 million to acquire more Patriot Advanced Capability-3 Missile Segment Enhancement missiles. Japan recently backtracked on plans to acquire the ground-based Aegis Ashore system following technical difficulties with the development of the SM-3 Block IIA interceptors, and is currently looking at alternatives. Japan's local defense industry will also get funding for various defense acquisition and research projects under the budget request, with the MoD seeking $643.7 million for three more Kawasaki P-1 anti-submarine aircraft and $487.5 million for two more C-2 airlifters from the same manufacturer. Japan's land forces are seeking $180.7 million for 25 more Type 16 wheeled maneuver combat vehicles, while the Japan Maritime Self-Defense Force has asked for $937.2 million and $654.1 million respectively to acquire two more frigates and the first boat of a new class of attack submarine. Research funding for Japan's next-generation stealth fighter to replace the approximately 90 Mitsubishi F-2s currently in service is also being stepped up, with $555.8 million requested and an additional $113.6 million sought for research and development of fighter subsystems such as radars and mission systems integration. A further $218.6 million will go toward the research and development of Japan's hypersonic weapons program, while the development of a standoff long-range electronic warfare aircraft based on the C-2 airlifter will require $144.9 million and a further $67.2 million requested for the acquisition of onboard systems to equip it. The budget request also includes funding for less traditional defense, such as the research and operation of space and cyber units, as well as for new electromagnetic warfare units. The electromagnetic unit would be based at the Japan Ground Self-Defense Force's Asaka base, north of Tokyo, and an unspecified number of staff would be deployed at several army bases across the country by March 2022, mostly in southern Japanese islands including Okinawa — areas of increased Chinese maritime and air activity. The mission of such a unit would be to block electromagnetic attacks that could disrupt thing such as radio and GPS functions. The ministry is requesting $66 million to purchase RC-2 reconnaissance aircraft, and about $218 million for research into surveillance systems to counter electromagnetic attacks by drones and other weapons. Japan in May launched the Space Operations Squadron as part of the Japan Air Self-Defense Force, with 20 initial members. It is expected to grow to about 100 members once the unit is fully operational in 2023. The unit is tasked with monitoring and protecting Japanese satellites from enemy attacks or space debris. It will also conduct satellite-based navigation and communications for other troops in the field. The ministry will launch a commanding unit in western Tokyo and staff size will be increased to 70 next year. It is seeking more than $680 million to design and launch a surveillance satellite, and develop and purchase equipment compatible with its ally the United States. The budget request will now be reviewed by Japan's Finance Ministry, which will then decide on the funding allocation for the various ministries and announce Japan's next budget, which is expected later this year. https://www.defensenews.com/global/asia-pacific/2020/10/01/japan-reveals-record-high-budget-request-supporting-hypersonic-tech-f-35-buys-and-more/

    US, UK launch military-space competition for startups

    By: Andrew Chuter LONDON – The U.K. and U.S. governments have turned to startups and inventors in a competition to adapt commercial technology solutions to answer pressing challenges in the military space sector. The two countries have jointly put up £1 million, or $1.3 million, to tap into potential new ideas in six technology areas from small companies, innovators and others around the world. The finalists will face a beauty parade in front of senior British, American and NATO military officials at a space conference scheduled to take place in London in November. Up to 15 proposals will be selected to go forward with further work on what is being called International Space Pitch Day. Launching the scheme, the U.K.'s first-ever, recently appointed director for space matters, Air Vice-Marshal Harv Smyth, said the initiative is “all about fast-tracking innovation and cutting-edge technology to the front line quicker than ever before, and fresh ways of working with industry to make sure we stay ahead of our shared adversaries and the threats they pose.” Smyth will be one of the judges at the conference, which will be held virtually if the live event is cancelled. The format will be the first international collaboration of its kind between two allies, the Ministry of Defence said. Organizations who make it through to the space conference final will be in contention to secure a $66,000 contract from the judges to speed up development of what is expected to be mainly commercial innovations and technology. The effort, run by Britain's Defence and Security Accelerator organization, is funded by the U.K. Defence Science and Technology Laboratory, the Royal Air Force and the US Air Force. The aim is to find, fund and fast track innovations by tech startups and other experts in order to accelerate the development of commercial space technology s to solve problems in the defense space sector. This year's competition is seeking solutions to six challenges set by the U.K. and U.S. space teams: Visualization of key events and information for combined space operations with allies and commercial partners. Understanding current satellite systems relevant to the operations of a particular commander. Understanding the present and potential impact of space weather on users across all domains. Provision of training against realistic threats and opportunities, incorporating live data, and integrating space across multiple domains. Enabling common and user-defined operational pictures to support multinational space domain awareness and command and control. A verification and comparison tool for space domain awareness, which can take orbital observation data from a variety of sources and in a variety of formats and produce a single, reliable operational picture. https://www.defensenews.com/global/europe/2020/07/22/us-uk-launch-military-space-competition-for-startups
