Study finds these gaps in Army’s small unit counter-drone capabilities

Army units at and below the battalion level are unprepared to defeat aerial drones and current plans can't keep up with rapidly evolving technology, according to a recent study.

Back in 2016, the Army Research Office asked an outside organization, The National Academies of Science, Engineering and Medicine, to evaluate their counter drone capabilities for battalion and below operations.

The report they published earlier this year notes some significant gaps and threats to soldiers with this technology.

“Contrary to the past, when U.S. warfighters may have found (improvised explosive devices), now the IEDs will find our warfighters,” according to the report.

While the Army and Marine Corps, which also included representatives in the study, are throwing resources at the small drone problem, they are not keeping pace with the threat.

“Army time frames are significantly out of sync with the rapidly advancing performance capabilities of individual (small Unmanned Aerial Systems) and teams of sUASs,” according to the report.

The report noted that most of the service's counter drone asset work was focused on heavy vehicle platforms or on fixed sites, which leaves smaller units most likely to first encounter the threat more exposed.

“Significant quantities of man-portable” counter-drone systems have been fielded, Army spokesman Maj. Chris Ophardt told Army Times in an email. The Army will continue to pursue those capabilities based on emerging threats.

Based on his response, which did not include details of capabilities, the Army is pursuing other ways to defeat drones. A large portion of the study was classified, due to operational security concerns.

“Future Army C-UAS systems will encompass a variety of potential platforms to include fixed, mobile, and Soldier-portable capabilities,” Ophardt wrote.

But beyond the types of systems employed, what they're targeting or attacking also came under fire in the report.

The Army and other branches have invested significantly in counter-drone technology, “often focusing on detecting radio frequency transmissions and GPS signals of individual sUASs. However, today's consumer and customized sUASs can increasingly operate without radio frequency (command and control) links.”

Drones now available can use automated target recognition, tracking, obstacle avoidance and other software-enabled activities instead of traditional RF and GPS.

Ophardt did not divulge specifics of how the Army is addressing this, but responded that the service's counter drone capabilities, “include multiple methods in order to detect, identify and defeat enemy UAS.”

A new school began last month at Fort Benning, Georgia to give basic trainees familiarity with small drones. The drone school gives infantry and scouts the ability to fill out a seven-line report when they encounter a drone then relay that info to their headquarters.

The students use both fixed-wing and helicopter small drones. They also learn defensive tactics such as how to use dispersal and hiding tactics to minimize casualties from drone-coordinated fires, according to an Army release.

Those introductory tactics can help even brand-new soldiers start thinking about how to deal with drone threats.

But, at the same time, the low-level tactics currently used for counter drone work have tried to use “kinetic effects,” basically shooting down the drone by interfering with its signals or overheating its circuits.

The report noted that method isn't practical on a wide scale for large numbers of troops, especially dismounted units.

That path only adds more gear from the equipment to the batteries, to an already overloaded soldier, not to mention the “cognitive load” of training and using another piece of equipment, according to the report.

Ophardt responded that the Army's counter-drone strategy included “multiple methods” to detect, identify and defeat” enemy drones.

The major provided a similar response when asked about Army efforts at counter-drone tactics, capabilities against swarming drones and collaboratively acting drone groups, which the report remarks will be more prevalent and sophisticated as soon as 2025.

Report authors urge Army leaders to adjust their timelines for matching tech development, which are woefully inadequate for the exponential changes in software, hardware and drone capabilities.

Current Army time frames consider near-term planning to run from now until 2025; mid-term planning in the 2026 to 2035 window and far-term at the 2036 to 2050.

Those efforts mirror vehicle acquisition strategy timelines, not the drone arena.

The report pushes for a near-term planning of one to two years, mid-term at the three- to five-year level and far term in drone tech at the six- to eight-year range.

The advances are happening so quickly, authors point out, that it is “impossible to predict performance capabilities beyond eight years.”

    MPF: Light Tank Competitors BAE & GD Head For Soldier Tests

    BAE and General Dynamics are vying to build 504 Mobile Protected Firepower vehicles to support light infantry units, especially in places the massive M1 Abrams cannot go. SYDNEY J. FREEDBERG JR. WASHINGTON: After 24 years without a light tank in Army service, soldiers will climb aboard brand-new Mobile Protected Firepower prototypes this January. “It's not just PowerPoint” anymore, Maj. Gen. Bryan Cummings, the Army's Program Executive Officer for Ground Combat Systems (PEO-GCS), told me in an interview. “On Jan. 4th, we will have ... vehicles arriving at Fort Bragg.” Army experts have already started safety testing on prototype MPF vehicles, officials told me. Actual combat soldiers will start training on two platoons of prototypes in January – four MPFs from BAE, four from rival General Dynamics – with field tests scheduled to begin in April. A formal Limited User Test will start in August or September, with the Army choosing the winning design in 2022 and the first operational unit of MPF entering active service in 2025. A General Dynamics spokesperson told me they've already delivered five MPF prototypes to the Army, with two more in final checkouts and another five being built for delivery by the end of the year. BAE Systems is also building 12 prototypes, but they declined to say whether they'd delivered vehicles yet or not. While the Army can't comment on either contractor while the competition is ongoing, Cummings said, “both are on track to meet the major milestones” – despite the disruptions of COVID-19. After three months of training, the troops will start what's being called the Soldier Vehicle Assessment (SVA): four to five months of intensive field testing, including force-on-force wargames. It's all part of the Army's new emphasis on getting real soldiers' feedback on new weapons early and often. “The soldiers actually get to drive the vehicles around, shoot them, train with them,” BAE business developer James Miller told me. “Their feedback [is] likely to be the most critical factor ... in the decision the Army's going to make about who wins this contract.” The soldier assessment isn't just testing out the vehicles, however, Cummings told me: It's also a test of the Army. Specifically, how can light infantry brigades, which today have few vehicles or mechanics, sustain and operate a 20-plus-ton tank? The crucial distinction: MPF is not going to the Army's heavy brigades, which have lots of support troops and specialized equipment to take care of tracked armored vehicles. Instead, 14 MPFs per brigade will go to airborne and other light infantry units, which haven't had tracked armor since the M551 Sheridan was retired and its replacement cancelled in 1990s. Now, MPF won't be as fuel-hungry or maintenance-intensive as the massive M1 Abrams, America's mainstay main battle tank. Even with add-on armor kits for high-threat deployments, it'll be less than half as heavy as the M1. That's because MPF isn't meant to take on enemy tanks, at least not modern ones. Instead, it's designed to be light enough to deploy rapidly by air, simple enough to sustain at the end of a long and tenuous supply line, but potent enough to take on enemy light armored vehicles, bunkers, dug-in machineguns, and the like. That's a tricky balance to strike. In fact, the Army has never found a light tank it really liked despite decades of trying. Only six M22 Locusts actually fought in World War II, the M41 Walker Bulldog was too heavy for airborne units, the M551 Sheridan was plagued by technical problems throughout its service from Vietnam to Panama, the M8 Armored Gun System and the Future Combat System were both cancelled. So how do BAE and General Dynamics plan to square this circle? General Dynamics emphasized lethality in their interview with me. Their Lima tank plant builds the M1 Abrams, and while the MPF is smaller – though the company didn't divulge details, GD's version reportedly has a 105mm cannon, compared to the Abrams' 120mm – it will have the same fire controls and electronics as the latest model of its big brother. “If you sat in a Mobile Protected Firepower turret, you would think you were sitting in a [M1] SEPV3 turret,” a GD spokesperson told me. “It's all the same displays, architectures, power distribution, etc.” GD's design evolved from their Griffin demonstrators, prominently displayed for several years at AUSA annual meetings. It's got automotive components derived from the ASCOD/Ajax family widely used in Europe and an 800 horsepower engine. GD didn't tell me how much their vehicle weighed, but, depending on the armor package installed, the demonstrators ranged from 28 tons to 50 tons. Those figures would give horsepower/weight ratios ranging from 28 hp/ton, better than any model of the Abrams, to 16, which would make MPF much more sluggish. BAE, by contrast, emphasized their design's compactness and ease of maintenance – considerations as critical as firepower for a light infantry unit. BAE actually built the M8 AGS cancelled in the '90s drawdown, and while they've thoroughly overhauled that design for MPS with a new engine, new electronics, and underbody blast-proofing against roadside bombs, they've tried to preserve its airborne-friendly qualities. “The old M8 fit inside a C-130; in fact, it was air droppable,” Miller told me. “There's no requirement for that in the current MPF program, but we decided to stick with that as a design constraint: [Our MPF can] fit inside a C-130; we can do three on a C-17.” BAE's engine is less potent than GD's, with only 550 horsepower. With the base configuration coming in at under 30 tons, that equates to over 18 hp/ton, with heavier armor packages reducing performance from there. But the big selling point of the engine is ease of access, Miller argued. Engine maintenance on a tank requires a crane and partially disassembling the armor, but a mechanic can slide the BAE MPF's engine in and out of the chassis with a hand crank. If the MPF breaks down or gets stuck, it can be towed away by a truck, without requiring a special heavy recovery vehicle as an M1 does. “The infantry brigades are light. They don't have long logistics tails. They don't have a ton of mechanics and recovery vehicles,” Miller emphasized. “The vehicle has to be as mobile as them and fit inside their organization.” The Army estimates the life-cycle cost of MPF, from development to procurement to maintenance and retirement, at $16 billion. Whichever vehicle wins the Army contract will have an edge in sales worldwide – including, potentially, to the Marine Corps, which is retiring its M1s as too heavy for modern amphibious warfare. https://breakingdefense.com/2020/10/mpf-light-tank-competitors-bae-gd-head-for-soldier-tests/
