    US Army sets timeline for long-range assault helo prototypes

    By: Jen Judson WASHINGTON — The U.S. Army is still considering two different paths to build prototypes for its future long-range assault aircraft following an industry day earlier this month, but is pushing toward a contract award in fiscal 2022, according to the service's FLRAA program manager. While the Army continues to sift through industry feedback to help it choose a route, the service remains on track to publish a draft request for proposals by the end of the year, followed by a finalized RFP in FY21, Col. David Phillips told reporters July 24. The Army chose Bell and Lockheed Martin's Sikorsky to enter into a competitive demonstration and risk reduction effort ahead of the start of the FLRAA program of record. The service is on a tight timeline to field a brand-new, long-range assault aircraft by 2030. The CDRR effort will consist of two phases that will last roughly one year each. Bell and a Sikorsky-Boeing team respectively designed, built and flew technology demonstrator aircraft as part a Joint Multi-Role Technology Demonstration phase prior to entering the CDRR effort. The companies will deliver initial conceptual designs, an assessment of the feasibility of requirements and trade studies using model-based systems engineering. “Due to the success of phase one (awarded on 16 March) the Army is looking at the scope of a second phase which would refine the digital designs from the system to subsystem level and further burn down risk as FLRAA enters into the [program of record,” Phillips said in a written statement to Defense News on July 27. The Army provided two schedules to get through the design and prototyping phase in an RFI in May to gain industry feedback. The first schedule lasts 52 months, putting the end of the prototyping period somewhere in the ballpark of early summer 2026. The schedule allows for a preliminary design review for just the air vehicle from the winning team — picked in the second quarter of FY22 — eight months after the contract award. The team would then have another preliminary design review for the weapon systems 17 months past contract award, which roughly falls around August 2023. The Army would hit the engineering and manufacturing development phase around October 2023, followed by a critical design review in early 2025. The first prototype would be delivered in the summer of 2025, with five more prototypes delivered through the summer of 2026. The alternative schedule would allow for a preliminary design review for both the air vehicle and the weapon systems at the same time at roughly 10 months following a contract award. This approach aims to get to an engineering and manufacturing development decision around March 2023. A critical design review would follow at the start of 2024, with a first prototype delivery expected around February 2025. All six prototypes should be delivered to the Army by roughly March 2026. The total time frame for the second option is 48 months post contract award. While the difference in schedules is just roughly four months, every week counts as the Army works to field new capabilities as fast as possible. Army leaders have often said that schedule is king when it comes to fielding the service's top modernization priorities. FVL is the third-highest priority, preceded only by a Next-Generation Combat Vehicle and Long-Range Precision Fires. The Army is driving toward entering a production and deployment phase in 2028 ahead of the first unit receiving the aircraft in 2030. “We believe FLRAA's design and requirements approach is inverting the defense procurement paradigm. Our approach gives the Army multiple opportunities to optimize requirements through digital engineering prior to entering the design, build, and test of the weapons system,” Phillips told Defense News. “Making informed decisions on requirements through design optimization will enable the Army to ensure FLRAA capabilities are affordable; meet [Multi-Domain Operations] requirements; and deliver on an aggressive schedule that does not sacrifice rigor for speed.” Multi-Domain Operations is the Army's war-fighting doctrine designed to operate and fight against anticipated future adversaries across land, sea, air and cyberspace Bell and Lockheed are also competing head-to-head to design and build the Army's future attack reconnaissance aircraft, which will follow a nearly simultaneous schedule as the FLRAA competition. https://www.defensenews.com/land/2020/07/28/army-still-mulling-different-paths-to-build-long-range-assault-helo-prototypes/

    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/
