Army Buys 9,000 Mini-Drones, Rethinks Ground Robots
WASHINGTON: This summer, Army soldiers will deploy to Afghanistan with air support literally in the palm of their hands: the 1.16-ounce Black Hornetmini-drone. New ground robots are entering service too, next year — not to fight but to haul supplies, at least at first — but field tests have convinced the Army to issue these often-cumbersome mechanical mules to specialists and only loan them to frontline troops as needed. By contrast, soldiers are so consistently and unequivocally enthused about the mini-drones that the Army is buying 9,000 systems — each with two drones — over three years to issue to its smallest and historically most vulnerable units, nine-man infantry squads.
The mini-drone and larger robots are all part of a wider revolution in the long-suffering infantry, a revolution sparked in large measure by former Defense Secretary Jim Mattis. The Marines, Mattis's old service, have issued upgraded 5.56 mm rifles and are adding a specialized drone operator to every rifle squad. The Army is going much farther, developing new 6.8 mm rifles, high-tech targeting goggles, virtual-reality training, and, of course, robots.
Now, none of these unmanned systems is truly autonomous, so they require a human to run them by remote control, which in turn requires a functioning battlefield network that hasn't been shut down by enemy jamming. The FLIR Black Hornet has a lot of automated functions and only flies short missions, so you don't need a soldier babysitting it all the time. Ground robots, however, require much more oversight, because they have to avoid rocks, bogs, tree stumps, and other obstacles that no unmanned air vehicle has to worry about and that artificial-vision software still struggles to spot. The Army is eager to improve the technology so that, instead of one soldier remote-controlling one robot, they can have one soldier overseeing a largely autonomous swarm. But even today's limited autonomy allows for big changes on the battlefield.
The palmtop Black Hornet — dubbed Soldier-Borne Sensor (SBS) by the Army — is already in the hands (literally) of a brigade of the elite 82nd Airborne that's about to deploy to Afghanistan. The second unit scheduled to get the mini-drone, starting this fall, is the 1st Security Force Assistance Brigade, which has already served in Afghanistan.
For the first time, a squad leader will have the ability to scout ahead by air before exposing human soldiers on the ground. The SBS has sensor options for both night and day, and it can fly about 20 minutes before needing to recharge.
But the squad-level mini-drone is just the entry model. Larger units will get larger, more capable, but also more expensive and more maintenance-hungry drones.
“Our vision is every echelon has unmanned aerial systems,” said Don Sando, civilian deputy to the commander of the Army's infantry and armor centerat Fort Benning, Ga. “The question is, how many?”
While squads get the Black Hornet SBS, platoons will get the slightly larger Short-Range Reconnaissance (SRR) drone, Sando and other Army officials told reporters in a conference call last week. A series of tests this month, September, and January will whittle six SRR competitors down to one that will enter service in April 2020. The winner must weigh three pounds or less, fly for 30 minutes, and be able to “perch and stare,” landing in a vantage point overlooking a target area so it can keep watch without burning through its flight time.
Companies will stick with the current RQ-11 Raven, which is still small enough that soldiers launch it by picking it up and throwing it.
Battalions currently use the Raven as well, but the Army plans to develop a new Long-Range Reconnaissance drone for them to use. The LRR isn't an official program yet, however.
Brigades currently have the RQ-7 Shadow, but that aging system needs a catapult to launch and a runway to land. It will be replaced by the Future Tactical Unmanned Aerial System (FTUAS), which takes off and lands vertically like a mini-helicopter, starting in 2021.
Divisions currently use the Grey Eagle, a variant of the venerable Predator, but the Army is experimenting with potential Advanced UAS drones to replace it too.
Ground Bots For Some
The Army is also fielding ground robots, but these machines are still much clumsier and harder to work with than aerial drones, so they're being issued only to specialist units. That includes what was formerly called the SquadMultipurpose Equipment Transport but is now renamed the Small Multipurpose Equipment Transport, because it's not going to belong to an individual squad.
The SMET, by either name, is still a small unmanned ground vehicle, about the size of a golf cart, designed to trundle along with the foot troops, hauling supplies and gear like an old-fashioned pack mule. It must carry 1,000 pounds of supplies and gear over 60 miles in 72 hours, trundling along with foot troops, and provide three kilowatts of power to recharge batteries for night vision goggles, radios, and other electronics.
Four competitors remain in contention: the Polaris MRZR, Howe & Howe Grizzly, HDT Wolf, and General Dynamics MUTT. “They're all viable candidates. They all met the standards of range, offloading power, silent watch capability, payload carrying,” Sando said. “Soldier feedback on all of them was very comparable with regard to what missions they're good for — and what conditions they're not appropriate for.”
The Army plans to field the winner starting next year to selected training centers, combat brigades, and support companies — but not infantry squads. “We found out in the operational tech demonstration [that] it can best be supported now at the battalion level,” Sando said, which is the lowest echelon of an infantry unit to include technical specialists such as a heavy weapons company. The Army's objective is to incorporate the new technologies without adding personnel to take care of them.
The issue with SMET is not just the maintenance the robots require — though that can be a large burden for a squad of nine — but also their limited mobility. “There are places where we ask our soldiers to go where nothing else can go... jungle terrain, steep embankments, water, and dense urban environments,” Sando said. “There are areas soldiers can walk and crawl and climb that we just couldn't put a vehicle of this size with them.”
The SMET remains very useful for long marches with heavy loads, the bane of infantry soldiers increasingly overburdened by body armor, ammunition, and electronics. Being able to recharge gear from the robot instead of carrying several days' worth of batteries for every item of equipment is itself a significant reduction in weight. Future SMET variants, Sando said, might carry long-range sensors, communications relays, or even weapons.
But when foot troops have to go places you can only go on foot, they need to be able to leave the robot vehicles behind and let someone else take care of them. By contrast, Sando said, “the Soldier-Borne Sensor is smaller than a pack of cigarettes, [so] I can use it when I need it, I can put it back.”

Boeing assembles team to bid for next-gen missile defense interceptor
Jen Judson WASHINGTON ― Boeing has assembled a team with General Atomics Electromagnetic Systems and Aerojet Rocketdyne to bid to build the Missile Defense Agency's Next Generation Interceptor (NGI). The agency decided last year to scrap its plans to redesign the kill vehicle of its current Ground-Based Interceptors (GBI) that is part of the Ground-Based Midcourse Defense (GMD) system designed to defend the homeland against possible intercontinental ballistic missiles from North Korea and Iran. The MDA is holding a competition instead to design a brand new interceptor for the GMD system. The company has an extensive history with the GMD system in place at Fort Greely, Alaska, and Vandenberg Air Force Base, California, having held the development and sustainment contract for years. That contract is set to expire in 2023 and MDA is weighing options to break up that contract to foster competition that promotes increased capability. “The Boeing-led team will deliver critical technology to enhance our homeland missile defense,” Norm Tew, Boeing Missile and Weapon Systems vice president, said in a Sept. 24 statement. “Combined, we bring decades of expertise in proven missile and weapon systems.” An NGI “requires a new way of thinking supported by a proven ability to deliver pioneering solutions,” Scott Forney, president of GA-EMS, said in a separate company statement issued Sept. 24. “We are excited to partner with Boeing to deliver the disruptive technologies needed to help MDA rapidly deploy an interceptor system that bolsters the nation's missile defense network and ensures that the U.S., our allies, and partner nations maintain military overmatch against ever evolving threats from adversaries.” Aerojet Rocketdyne will supply the propulsion system. “As the country's premier hit-to-kill propulsion provider, we're able to deliver low-cost, high-performance systems by leveraging our skilled workforce and strategic investments in innovative technology and materials,” Eileen Drake, Aerojet Rocketdyne CEO, said in the Boeing statement. Boeing reports the team submitted its NGI offering to MDA on Aug. 12. Also according to the statement, Northrop Grumman will serve as a “component supplier” on the Boeing team. Northrop is also teaming up separately with Raytheon to compete against the Boeing team and Lockheed Martin. Raytheon was the developer of the now-canceled RKV. MDA aims to downselect to two companies later this year, who will then compete for the right to build the interceptor. Proposals were due July 31, but MDA noted in its request for proposals that there may be some give in that schedule due to the ongoing COVID-19 coronavirus pandemic. The agency requested $664.1 million in fiscal year 2021 for the NGI program, as part of a $4.9 billion five-year budget plan. https://www.defensenews.com/2020/09/24/boeing-assembles-team-to-bid-for-next-gen-missile-defense-interceptor/

Hypersonic weapons could give the B-1 bomber a new lease on life
By: Aaron Mehta NATIONAL HARBOR, Md. — It's been a rough stretch for the U.S. Air Force's fleet of 62 B-1B Lancer bombers, with a pair of fleet shutdowns over safety concerns and the confirmation of plans to start retiring the plane as the new B-21 comes online, even as the much older B-52 remains in service. But speaking at the Air Force Association's annual conference Monday, Gen. Timothy Ray, the head of Air Force Global Strike Command, seemed to throw his support behind keeping the B-1 around for quite some time. In fact, in Ray's mind, the B-1′s capabilities might expand. Several times throughout the speech, Ray emphasized that while the B-21 is slowly spinning up, he can't afford to lose any capability. Indeed, Ray seemed to posture toward keeping the B-1 over the long term, according to John Venable, a senior defense fellow at the Heritage Foundation and former F-16 command pilot. “One of the major takeaways [from the speech] is that the B-1 is not going to go away nearly as soon as people thought,” Venable said, “and that's a good thing.” Under the Air Force's stated goal of 386 squadrons, the service's force mix requirement is about 225 bombers. The service currently has 156, Ray said, and even with the B-21 coming online sometime in the 2020s, planned retirements to the B-1 and B-2 would keep the bomber force under 200. Ray's belief in the B-1 spans from two broad assessments. First, freed from the heavy workload of B-1s performing regular close-air support activities in Iraq and Afghanistan, the fleet will experience less wear and tear, and hence survive longer than projected. “We're just flying the airplane in a way we shouldn't have been flying it, and we did for far too long. The good news is we're resetting that entire team,” Ray said. “What we thought was a very sizable load of structural issues” ended up being a “fraction” of issues to deal with, he added. Those structural issues have become particularly visible in the last 16 months, with the entire B-1 fleet grounded twice for mechanical issues. In June 2018, the fleet was grounded for two weeks following the discovery of an issue with the Lancer's ejection seat; in March 2019, another ejection seat issue grounded the fleet for almost a month. Members of Congress have since expressed serious concerns about the B-1's readiness rates, a number that was just more than 50 percent in 2018. Ray expressed optimism about the mechanical issues, saying that any fallout from the ejection seat shutdowns will be completed by the end of October, which is “must faster” than the service predicted. The second reason Ray believes there's still life in the B-1? The idea that there are modifications to the Lancer that would add new capabilities relevant in an era of great power competition. In August, the Air Force held a demonstration of how the B-1 could be modified to incorporate four to eight new hypersonic weapons by shifting the bulkhead forward from a bomb bay on the aircraft, increasing the size inside the plane from 180 inches to 269 inches. That change allows the loading of a Conventional Rotary Launcher, the same system used inside the B-52, onto the B-1. According to an Air Force release, first reported by Military.com, the bulkhead change is temporary, giving the B-1 flexibility based on its mission. Overall, the internal bay could be expanded from 24 to 40 weapons, per the service. In addition, the testers proved new racks could be attached to hardpoints on the wings. “The conversation we're having now is how we take that bomb bay [and] put four potentially eight large hypersonic weapons on there,” Ray said. “Certainly, the ability to put more JASSM-ER [Joint Air-to-Surface Standoff Missile Extended Range] or LRASM [Long Range Anti-Ship Missile] externally on the hardpoints as we open those up. So there's a lot more we can do.” Said Venable: “I think it's a great idea. Increasing our bomber force end strength, we're not going to get there just by buying B-21[s] and retiring the B-1s.” “Adding a new rotary [launcher that] he was talking about, just behind the bulkhead of the cockpit of the B-1, freeing up the pylons to actually manifest more longer-range weapons and give it a greater penetrating strike capability — those are great takeaways from this particular event,” the analyst added. https://www.defensenews.com/digital-show-dailies/air-force-association/2019/09/17/global-strike-head-makes-case-of-b-1-survival/
