By Matthew Cox The Army general in charge of modernizing soldier lethality said recently he is confident that the service will begin replacing both M249 squad automatic weapons and the M4 carbines in infantry brigades in 2023. Army testers are currently shooting the first 6.8mm rounds through a variety of rifle and automatic rifle prototypes of the Next Generation Squad Weapon (NGSW) at Aberdeen Proving Ground, Maryland, Brig. Gen. David Hodne told Military.com at a June 16 Army Futures Command media event. The service's goal is to select a final design for both weapons from a single provider in the first quarter of 2022 and begin replacing M4s and M249s in an infantry brigade combat team (IBCT) in the first quarter of 2023, said Hodne, director of the Army's Soldier Lethality Cross Functional Team. "We are going to do both," he said, explaining the Army won't be sure how long it will take to equip that first IBCT until it can evaluate the winner's production capability. "The first unit equipped spans a period of months, and that first unit equipped will include both [weapons]," Hodne said. The NGSW effort is part of the modernization strategy being orchestrated by Army Futures Command (AFC). Based in Austin, Texas, the command will reach full operating capability as of July 31, AFC Commander Gen. Mike Murray told reporters at the event. Both the NGSW carbine and automatic rifle are being designed to fire a special, government-designed 6.8mm projectile that Army leaders say will penetrate modern enemy body armor at greater distances than the current M855A1 5.56mm Enhanced Performance Round. The Army intends to conduct live-fire tests on NGSW prototypes from several gun makers until August, when it is scheduled to select up to three vendors that will move to the next phase of testing, Hodne said. The August down-select will involve the companies that participated in the Army's second prototyping opportunity notice (PON), released in January, that directed gun makers to develop prototypes of both the rifle and auto rifle versions of the NGSW to ensure both work with the common 6.8mm projectile. Army officials would not release the names of the companies chosen to make prototypes for the second PON effort. Last July, the service awarded contracts for the first PON effort to several companies, but that effort involved only prototypes for the automatic rifle version of the NGSW. "We learned a lot in this process. ... Industry took a very hard problem, and they have developed some very innovative solutions," Hodne said. "The first prototyping opportunity notice was centered around an automatic rifle. What we learned was -- to get the best rifle and the best automatic rifle -- we realized the approach had to be centered around a common cartridge that was supportable by both systems." The Army left it up to vendors to design the type of 6.8mm cartridge they wanted to use in their prototypes, Hodne said, adding that some gun makers went with "traditional bottleneck" brass cartridges while others used newer, case-telescoped cartridges. Another part of the NGSW effort is the advanced fire control system, which is being designed to calculate range to target, atmospheric conditions, and the ballistics of both weapon and ammunition, according to the May 30 prototype opportunity notice. The Army expects to receive fire-control prototypes sometime in October, according to Brig. Gen. Anthony Potts, commander of Program Executive Office Soldier. "People as, 'Is the technology going to be there?' " Potts said. "The answer is yes. ... I am very enthused about next generation squad weapon ... it's not just an evolution in capability. It's a revolution in capability. It really will change the lethality of our squads." https://www.military.com/daily-news/2019/07/17/army-reveals-timeline-fielding-new-infantry-weapons.html

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/
