SOCOM wants a new armor piercing sniper bullet. Here’s one option engineers are developing

By

As the U.S. military shifts its focus back to fighting more traditional, near-peer adversaries like Russian or Chinese troops, the services are building out plans to revamp their gear to deal with better-equipped forces backed by money and technology from world powers.

That extends all the way down to the clothing and equipment each of these adversaries could be wearing into battle, including sophisticated body armor.

That's why SOCOM is reportedly looking at replacing its decades-old armor piercing small arms round.

“Snipers in USSOCOM units have a capability gap in their ability to penetrate enemy body armor, small boat engines and concrete barriers,” Crane researchers said in a slide presentation at this year's National Defense Industries Association Armaments Symposium.

The current round uses a discarding sabot the shields a sharpened tungsten penetrator that'll beat most armor and hard targets.

But that round is expensive at more than $10 per cartridge, can damage modern small arms accessories like suppressors and muzzle brakes and doesn't hold zero when switching from a traditional jacketed round to the AP round. That makes it difficult for snipers to go from one round to another and hit their target in the heat of battle.

So researchers at the Naval Surface Warfare Center in Crane, Indiana, are looking at a new way to make the rounds cheaper, easier on snipers' guns and more ballistically consistent with common, jacketed bullets.

Dubbed “aeroshell” projectiles, the Crane engineers want to build and test bullets with a tungsten penetrator jacketed in a polymer shell. Federal Ammunition, a civilian ammo company, makes rounds with similar characteristics dubbed “Syntech."

These rounds are typically used by competitive shooters who shoot many rounds in practice and at matches and want to preserve barrel life and diminish spawl from hitting steel targets.

Crane researchers want to take the same thought process and apply it to a new AP round. The actual penetrator could have a slightly different shape than the current rounds, with more of a traditional bullet profile than today's needle-like AP round penetrator.

Researchers plan to create about 150 rounds of this new aeroshell AP round in .338 Norma Mag, 300 Norma Mag and 6.5 Creedmoor. They plan to test the rounds against representative body armor at 100, 400, 800 and 1,000 meters.

    Army Invites Air Force ABMS To Big Network Test: Project Convergence

    This fall's experiment will study how the Army's own weapons can share target data, Gen. Murray said, but in 2021 he wants to add the Air Force's ABMS network. By SYDNEY J. FREEDBERG JR.on May 28, 2020 at 5:06 PM WASHINGTON: Damn the pandemic, full speed ahead. The four-star chief of Army Futures Command plans to hold a high-tech field test in the southwest desert this fall, COVID-19 or no. Called Project Convergence, the exercise will test sharing of targeting data amongst the Army's newest weapons, including aerial scouts, long-range missile launchers and armored vehicles. The Army also wants to plug in its new anti-aircraft and missile defense systems, AFC head Gen. Mike Murray told reporters, but those technologies are at a critical juncture in their own individual test programs – some of which was delayed by COVID – and they may not be ready on time for this fall. “I'm going to try to drag them all into this,” Murray said. The experiment, set to begin in late August or early September, will definitely include the Army's Artificial Intelligence Task Force, as well as four of its eight modernization Cross Functional Teams. That's Long-Range Precision Fires (i.e. artillery), Future Vertical Lift aircraft (including drones), and the tactical network, he said, plus the Next Generation Combat Vehicle team in “a supporting role.” What about the Air & Missile Defense team? “We'll see,” Murray said. “Right now... I'm very cautious, because of the two major tests they've got going on this fall in terms of IBCS and IMSHORAD.” IBCS is the Army's new command network for air and missile defense units, which had to delay a major field test due to COVID. IMSHORAD is an 8×8 Stryker armored vehicle fitted with anti-aircraft missiles and guns, which Murray said is now delayed “a few months” by software problems. Meanwhile, the Air Force – with some input from the other services – will be testing its own nascent data-sharing network. That's the ambitious Advanced Battle Management System, the leading candidate to be the backbone of a future Joint All-Domain Command & Control (JADC2) network-of-networks linking all the armed services. The Air Force's ABMS experiment will be separate from the Army's Project Convergence exercise happening at roughly the same time this fall, Murray said. But he wants to hold a Convergence test each year from now on, he told reporters, and he wants to bring in ABMS in 2021. “In '20, we're parallel, not interconnected,” he said. “Our desire is to bring them closer and closer together, beginning in '21.” Sensor To Shooter Murray spoke via phone to the Defense Writers Group, along with the Army's civilian chief of acquisition, Bruce Jette. While the two men's roles and organizations are kept distinct by law, they've been joined at the hip on modernization, and Jette – a scientist, engineer, and inventor — is clearly enthused about the experiment. “We are looking at the potential integration of all of our fires into a fires network,” Jette told the listening reporters. Currently, he explained, the Army has one network, AFATDS, to pass data about ground targets to its offensive artillery units – howitzers, rocket launchers, surface-to-surface missiles. Meanwhile, it's developing a different network, IBCS, to share data on flying targets – incoming enemy rockets, missiles, and aircraft – amongst its air and missile defense units. The two networks and the sensors that feed them must meet very different technical demands, since shooting down a missile requires split-second precision that bombarding a tank battalion does not. But there's also great potential for the two to share data and work together. For example, the defensive side can figure out where enemy missiles are launching from, then tell the offensive side so it can blow up the enemy launchers before they fire again. “If I can bring the two of them together,” Jette said, you can use a sensor the Army already developed, bought and fielded to spot targets for one weapon – say, the Q-53 artillery radar – to feed targeting data into a totally different type of weapon – say, a Patriot battery. Artificial intelligence could pull together data from multiple sensors, each seeing the same target in different wavelengths or from a different angle, to build a composite picture more precise than its parts. “We're moving past just simple concepts of sensors and shooters,” Jette said. “How do we get multiple sensors and shooters [integrated] such that we get more out of them than an individual item could provide?” Looking across the Army's 34 top modernization programs, Murray said, “an individual capability is interesting, but the effect is greater than the sum of the parts. There have to be connections between these [programs]. And that's really the secret sauce I'm not going to explain in detail, ever.” Testing, Testing What Murray would share, however, was that the Army got to test a slightly less ambitious sensor-to-shooter link in Europe earlier this year, as part of NATO's Defender 2020 wargames. The field experiment fed data from a wide range of sources – in space, in the air, and on the ground – to an Army howitzer unit, he said. However, the Army had also wanted to experiment with new headquarters and organizations to command and control ultra-long-range artillery, Murray said, and those aspects of the massive exercise had to be cancelled due to COVID. The service is looking at alternative venues, such as its Combat Training Centers, but “it's just hard to replicate what Defender 2020 offered us,” he said. “What we lost was the largest exercise we've done and the largest deployment of forces in a very, very long time.” That makes the stakes even higher for Project Convergence. “You can call it an experiment, you can call it a demonstration,” Murray said. “Right now, the plan is we're going to do this every year... every fall as we continue to mature... this architecture that brings the sensors to the right shooter and through the right headquarters.” While this year's Convergence exercise will focus on the Army, Murray is already working with the Air Force to meld the two next year. “We have been in discussion with the Air Force for the better part of the year on how we integrate with the effort they have going on,” he said. “I was actually out at Nellis the last time they had a live meeting on JADC2 [Joint All-Domain Command & Control] with all of the architects of ABMS.” Those discussions made very clear to both the Army and the Air Force participants that “it all comes down to data and it all comes down to the architectures you build,” Murray said. “As Bruce [Jette] talked about, it's not a specific sensor to a specific shooter,” he said. “On a future battlefield... just about everything is going to be a sensor. So how you do you store that data and how do you enable a smart distribution of data to the right shooter? Because we can't build architectures that are relying upon huge pipes and just massive bandwidth to make it work.” https://breakingdefense.com/2020/05/army-invites-air-force-abms-to-big-network-test-project-convergence

    U.S. Air Force will fund research into tech that enables eVTOL aircraft

    The U.S. Air Force is looking to fund research into “deep tech” for eVTOL aircraft through its next round of Small Business Technology Transfer (STTR) contract awards. By Elan Head An award-winning journalist, Elan is also a commercial helicopter pilot and an FAA Gold Seal flight instructor with helicopter and instrument ratings. Follow her on Twitter @elanhead View more posts NEWS U.S. Air Force will fund research into tech that enables eVTOL aircraft Monday July 6, 2020 The U.S. Air Force is looking to fund research into “deep tech” for eVTOL aircraft through its next round of Small Business Technology Transfer (STTR) contract awards. The focus on technology research is one more aspect of Agility Prime, the Air Force's effort to accelerate development of the commercial eVTOL industry with the goal of establishing U.S. dominance in this emerging field. Speaking during an Agility Prime webinar on July 1, Dr. Will Roper, Assistant Secretary of the Air Force for Acquisition, Technology and Logistics, suggested that the Air Force could help fill a funding gap left by Silicon Valley investors who have increasingly prioritized software enterprises that promise faster returns. “We want to take risk by investing in deep tech,” he said. “For programs like Agility Prime that are going to be tackling a lot of really tough challenges — from power to flight safety to logistics — there's a lot of really cutting-edge tech that has to be created, has to be matured and developed, if we're ultimately going to bring this market to bear in the U.S. first. Well, STTR is a great place to start tackling the hard challenges now.” STTR is a federal government program created to help commercialize compelling technology from across the U.S. research community. Like the Small Business Innovation Research (SBIR) program, it focuses on three phases — concept development, prototype development and commercialization — with various funding amounts available for different phases. Unlike SBIR, however, STTR requires that participating small businesses partner with an eligible nonprofit research institution. According to Roper, the Air Force devotes around $700 million per year to SBIR and another $200 million to STTR projects — not all of which will yield results. “We don't expect every company in STTR to succeed, just like we don't in SBIR,” he said. “This is an investment portfolio, so we're looking for return across the whole portfolio, not [on] a company-by-company basis. But we should start planting the long-lead seeds now, because if we don't, they're not going to bloom in time for us to harvest in a way that will benefit programs like Agility Prime.” The Air Force's next STTR Open Topic solicitation will include an Agility Prime focus area, intended to survey a large scope of technologies including autonomy, advanced aircraft materials and manufacturing, novel acoustics techniques, and sense-and-avoid systems, to name a few. The Air Force expects to award an estimated $10 million worth of phase one contracts for values up to $150,000 within 90 days. According to Jared Evans, a partner in AFVentures who also spoke during the webinar, phase two contracts are expected to have an initial value of $750,000, with the most promising projects then eligible for a “strategic fund increase” up to $30 million. “Ultimately, our end goal here is . . . transitioning to a full program of record,” he explained. “There's no STTR funding for that, but there's also no limit on government input or private investment.” In advance of the solicitation, the Air Force innovation division AFWERX will be hosting a virtual TeamUp event with the Air Force Research Laboratory (AFRL) on July 15 and 16. The first day of the event will be open to the public and will include an overview of STTR funding opportunities, plus a virtual trade show. The second day will be restricted to Agility Prime ecosystem members who have chosen to register for a virtual booth, with the aim of facilitating connections that could lead to collaborative STTR proposals. Registration for the event is available here. “TeamUp events like this one will provide opportunities for multiple stakeholders to come together and compete with speed,” stated AFWERX director and Agility Prime team lead Col. Nathan Diller in a press release announcing the event. “Just like AFWERX and AFRL are teaming up to bring cutting-edge commercial technology together with world-class research, we are encouraging entrepreneurs and researchers from around the country to ‘TeamUp' in a way that strengthens our national security and prosperity.” https://evtol.com/news/air-force-agility-prime-sttr/
