Exclusive Interview with US Army Next Generation Squad Weapon Program Leaders

TFB had the pleasure of speaking with Lt. Col. Jason Bohannon, Product Manager – Next Generation Weapons, and Matthew Walker, Capabilities Developer, Soldier Lethality Cross Functional Team at U.S. Army Futures Command, to discuss the program, the weapons and the challenges ahead.



FB: So expanding on that, can you comment on the types of units those involved are drawn from?

Walker: “Those involved are a broad, diverse group, with guys drawn from the line divisions, Special Operations Command and the Marines. The guys who we’re looking for to provide feedback are all senior but don’t get me wrong, there is an inclusion of younger guys … who definitely have input to make since training is such an important aspect of how well a person does with these new capabilities. Take the fire control unit; It benefits a sub-standard shooter and also benefits an expert marksman. We can see analytically that the fire control unit improves both. We’re not trying to replace training, obviously, but it’s a sliding scale, the more trained you are the better you can make use of the capabilities of the NGSW …”

TFB: As the program goes forward, will both weapon systems be selected from one manufacturer, or is there potential to take an NGSW-R from one and an NGSW-AR from another, providing ammunition commonality was feasible? Is there flexibility for this kind of outcome built into the procurement plan?

Bohannon: “Right now, the plan is to choose the rifle and automatic rifle from the same vendor. We’re fully funded, and the requirements are pretty stable to achieve that. However, I would say we maintain some flexibility. At the end of the day, if it was decided that there was an alternative solution, we might approve one gun and continue on a separate path for another. Soo there is flexibility for an off-ramp, but right now everyone is planning for one vendor.”

TFB: Is there similar flexibility to use one manufacturer’s ammunition plan with another manufacturer’s weapon design?

Bohannon: “Ultimately, that comes down to the selection criteria. We have to weigh the benefits and weaknesses of the rifle, the automatic rifle, the manufacturing capability and special license agreements.”

TFB: In terms of the NGSW Fire Control Unit, when are the prototypes from the recently awarded contracts for NGSW-FCUs set to join the Soldier Touch Points process?

Bohannon: “The very first thing we did once the award was official was give (vendors) access to high-quality shooters. So we took both of those vendors [Vortex & L3Harris] to Fort Benning, Georgia, and Soldiers from the Army Marksmanship Unit, 75th Rangers and conventional forces gave feedback on things like reticle patterns, menus, button placement, etc. We provide the range, the marksmen and the safe conditions for feedback and the vendors can spend the week collecting feedback that we expect they will include in their design process. That’s something that traditionally isn’t done, but it’s worked well for us. We did the same thing at the beginning of the competition last year; As soon as we down-selected, we took the guns down to Fort Bragg. It was very beneficial.”

TFB: For the FCU, were there only two slots planned for the down-selection?

Bohannon: “We planned to select up to two. We could have gone with just one, but we had two really solid submissions. We really hoped to see a competitive environment… and I think we have that in both the fire control unit and the weapons competition.”

TFB: Can you comment on the environmental aspects of the polymer-cased ammunition used by 2 of the 3 ammunition entries? Are the potential environmental impacts of this something that the Army has considered? Has the potential pollutant effect of polymer been factored into the program?

Bohannon: “You’re the first person to ask me about that! The Army over time has always sought to minimize environmental impacts where possible. We took lead out of the M855A1, so there is always a desire to reduce negative environmental impacts.  At the same time, you’ve got to balance that with soldier load and capitalizing on emergent technologies. So for the last two years, offices around the Army have been exploring alternatives to the traditional brass case, and we’ve seen some really innovative efforts.”

Matt Walker: “The desire to eliminate toxic products from being used by Soldiers is something that in the last two decades the Army have been making big strides. That hasn’t always been the case. There’s probably less of an impact from polymers than there is from injecting all those metals into the environment. We’re trying now to remove residual lead from primers, too.”

TFB: In turn, how do you mitigate complex and harsh environments impacting ammunition with not traditional components like polymer?

Walker: “Plastic and polymer is relatively inert and doesn’t really interact with the environment.”

Bohannon: “We’ll be doing the same testing that we would on brass cases, so we’ll take them to extreme hots and colds. We’re really trying to stress these systems to the point of failure, so we know where their left and right limits are, and ultimately the Soldier Lethality Cross Functional Team and Maneuver Center of Excellence at Fort Benning will be able to determine if that performance is acceptable for an Infantryman that has to operate in extreme environments.”

TFB: Moving away from the environmental considerations, NGSW-AR has been positioned as a replacement for the M249 SAW, but with 6.8mm GP potentially outperforming M80A1 and XM1158 in terms of velocity and penetration. Will it also replace the 7.62x51mm M240?

Walker: “There’s an awful lot of discussion about that. When we talk about the range and energy at range and the ability to make use of that energy against a target, 6.8 GP is definitely showing itself to be pretty capable of being competitive against the 240 machine gun. There’s work to be done. This is obviously the first entry into this next growth area of small arms. As we take this step with these weapons into the next growth area, because remember some of those systems – the M16, M4, M27 – have had fifty years of evolutionary improvement, The NGSW are just the first step, so we don’t even know what they’ll look like in 10-15 years from now. So maybe we’ll replace the 240, or maybe there’s another program down the line that’s a more robust approach, perhaps a little heavier, a little bit longer barrel, maybe weighs a few pounds more… and maybe we would be able to go to a common cartridge for the entire platoon, which obviously, logistically would be beneficial. Actually, we’ve had this discussion with a couple of corps commanders who asked the exact same question: Are we looking to replace something in the weapons squad? Are we looking at increased capability? That remains to be seen.”

TFB: Is the performance specification for the 6.8mm GP-based rounds still in flux? Can we get confirmation of projectile weight and minimum expected velocity?

Bohannon “We’re still not giving out any data with regard to velocity or effects of the system. Like all of our rounds, they started out at Lake City Army Ammunition Plant and throughout time, they continue to get better and better in terms of tolerances and variances. So it’s going to outperform anything on the battlefield today, and it’s going to continue to evolve, become more and more accurate the more rounds that Lake City builds. To date, they’ve manufactured almost a million projectiles.”

TFB: What is the expected role of the M4 after NGSW weapons begin to be fielded? Will it fill an M1 Carbine-esque echelon role or gradually be phased out entirely?

Walker: “Vietnam was the last time we really had the separation of weapon types between the Close Combat Forces. While most engagements are somewhere between 150 and 250 meters, there’s really not a lot of long range shots.  But there is a need, in our view, for the close combat Infantryman to have a weapon that affords him the capability specifically against near-peer threats to still reach out and touch somebody at range. The M4 will remain in the force in Brigade Combat Teams. The NGSW-AR will replace the M249s in the [Squad Automatic Weapon] role, but the 249s in the LMG role – those will stay in light machine gun roles where they’re equipped with a longer barrel, etc.”

TFB: Integrated powered rails are a desire for the successful weapons. What sorts of accessories is the Army seeking to power with the rail, and what is an acceptable weight to lethality increase ratio?

Bohannon: “That’s a good question; we debated with that. We looked at what we need to do to just add the rail itself – the Picatinny smart rail; you’re not really adding weight. It’s when you start running a conduit or any kind of batteries. But the ability for that rail to either pass power or data through is an attempt to create a kind of open architecture on the weapon system. Once that open architecture exists, a market space exists, so like laying fibre optics in your house before you had Fios. At the end of the day, this gun has to do a few things: it has to kill; it does not have to pass data and power to be successful. But that is something we can continue working. We really wanted the vendors to think through how they would do it at the earliest stages of development.”

TFB: Has the Covid-19 pandemic had any impact on the program? Have there been any major delays to the evaluation process? Can we expect to see the awarding of final contracts delayed?

Bohannon: “It’s been a tough couple of months that have forced the team to re-plan and stay in a reactive state. There was no pause, we had to adapt. We did see some sub-suppliers that had issues and we had to delay the technical testing by 30 days. Then we found ways to restructure deliveries downstream and restructure testing in order to sustain a six month timeline before the record test. Overall, we’ve had no slip of the program delivery date but it’s an aggressive schedule. We’ve been able to accomplish this through an adaptive team of professionals that talk regularly with the vendors, sometimes a few times a week. We treat it as a partnership.”

TFB: What are the immediate program priorities at the moment?

Bohannon: “We’re going to be in this development for the next year. Prototype test #2 is scheduled to start next year in the spring of ’21; that’s the record test. Everything we’re doing this summer is the diagnostic test. The vendors will receive the raw data from that, to preposition them to be as competitive as possible next year.”

TFB: Finally, could you elaborate on what the biggest challenges the NGSW concept faces before it becomes a mature weapon system?

Walker: “All of the weapons I’ve fired are capable, and all of them, in their own way, are ingenious or novel. Also, there’s an awful lot of attributes that have been added ergonomically that only a person that uses a weapon as the tool of their trade would appreciate – things being where they’re supposed to be, so you can operate them quickly. Over time, some weapons have not afforded that. We’re now seeing that Soldiers system concept – designing things as a system, not trying to integrate features once they finally arrive with the Soldier. To make industry bring to the table a consolidated approach for their system. You’ll remember with the Modular Handgun System a couple of years ago … we did not define the calibre, we just said ‘It has to be able to do this …’, and we were willing to adapt in the event vendors brought forward something better. It’s just a different way over the last six to eight years, of doing acquisition. There have been a lot of bruises and scrapes and bumps over time, but some of the biggest challenges are just going to be gaining consensus and making an informed decision.”

Bohannon: “When I boil my job down, it really comes down to managing risk and there’s risk associated with all programs. I look at money, requirements and authority.  When we started this program a couple of years ago, there were a lot of unfunded requirements, and Army was still trying to decide if it was going to accelerate the rifle and treat this as a systems approach with the fire control unit.  Now we’re fully funded. I’m pretty fortunate, there are very few PMs in the world that have a good requirement and have a good relationship with the requirement’s developer… Matt and I have worked for years together, and we’ve debated small arms developments dating back to the 1950s, the Special Purpose Infantry Weapon and all the subsequent developmental efforts.

“There are mitigations that we applied to this program that at a strategy level didn’t exist for really big efforts. For instance, the Future Combat Weapon or OICW, these were large scale developmental programs that really shot for the moon. Ours was banded by five years and five years and had heavy vendor input because we believed if it couldn’t be developed in five years, it would be too hard to maintain momentum and support. We completed a series of market research days with industry. We had classified market research days, we hosted vendors at Fort Benning and Picatinny Arsenal to discuss some really hard challenges, they were difficult conversations for us to have. Jumping forward to today, we have a very healthy competition going, so I believe that the Army has learned from the issues of the past and pivoted to this new way of doing acquisition. We are using middle-tier acquisition authority, which is not typical, we’re not using a traditional DoD requirement documents. Like all programs, when you’re doing something hard, you’re going to have some road bumps along the way but this method should give the Army flexibility and I think ultimately this is the way we should be doing business.”

The Next Generation Squad Weapon program is one of the U.S. Army’s top modernization priorities, and we will continue to follow its progress over the next 12 months as the testing continues and a vendor is selected. NGSW could herald some major shifts in small arms development, and we’re grateful to Lt. Col. Bohannon and Mr. Walker for taking the time to speak with us and give us some insight into the program.

AUSA 2020: Bell to begin building 360 Invictus imminently
by Pat Host

Bell will start building its 360 Invictus helicopter this week. The company is developing the 360 Invictus for the US Army’s Future Attack Reconnaissance Aircraft-Competitive Prototype (FARA-CP) programme, according to a company official.

Chris Gehler, Bell FARA vice president and programme director, told Janes on 8 October ahead of the Association of the United States Army (AUSA) annual trade show that Bell has already begun building gearboxes, rotor pieces, and airframe structure for the 360 Invictus. Bell is about to begin building the rotor blades for the aircraft and has already started manufacturing main rotor blade extensions. The company, he said, has already built blades that it used to performed process verification and destructive testing.

Many of the 360 Invictus’ drive system and rotor components are in manufacturing and nearing completion. Gehler expects most of the drive system and rotor components to be completed by December. This is because Bell traditionally prioritises building the gearboxes and rotor system first to test them in a drive system test lab to reduce future maintenance. Bell will build the 360 Invictus in Amarillo, Texas.

Bell intends to have the 360 Invictus assembled by the third quarter of 2022 for a ground run in the same timeframe. Bell wants the aircraft ready for its first flight in the fourth quarter of 2022.

BAE Systems Offers Archer Wheeled Howitzer for U.S. Army’s 155 mm Gun System
(Source: BAE Systems; issued October 19, 2020)

WASHINGTON --- BAE Systems has proposed its ARCHER howitzer in response to the U.S. Army’s request for proposals for a 155 mm wheeled gun system. ARCHER is a fully automated weapon system that provides highly responsive and versatile fire support to troops in combat.

BAE Systems is offering ARCHER for participation in the Army’s plans to conduct a “shoot off” evaluation early next year at the Yuma Proving Ground in Arizona. The Army’s RFP, released on July 30, looks to evaluate mobile howitzers in support of future Army requirements. ARCHER is already in service with the Swedish Army with the highest technical and manufacturing readiness levels.

“ARCHER is a mature, proven system that can quickly get into the fight and strike enemy targets at long ranges, with a high rate of fire and very fast displacement times, and is made for combat against large power adversaries,” said Chris King, director of business development at BAE Systems. “With a fully automated system, soldiers can execute their mission with minimal physical exertion and time, while remaining under cover in the armored cabin. The cab protection, fast shoot and scoot times and its extended range all enhance survivability and sustain fire support in harsh combat conditions.”

ARCHER brings a single, fielded package of capabilities that would provide U.S. soldiers with responsiveness and flexibility that far exceed current capabilities. ARCHER is typically operated by a crew of three to four soldiers but can be operated by only one.

ARCHER can fire within 30 seconds of receiving an order. It can then depart its firing position within 30 seconds, minimizing the enemy’s ability to effectively return fire. Its magazine carries 21 rounds and can unload all of them in less than three minutes.

ARCHER can fire the BONUS anti-armor munition up to 35 km, conventional munitions up to 40 km, and currently fielded precision-guided munitions like Excalibur in excess of 50 km. BONUS and Excalibur are currently in the U.S. Army’s inventory.

ARCHER is manufactured by BAE Systems Bofors, which is based in Karlskoga, Sweden.

US Army gets first Infantry Squad Vehicle from GM Defense


GM Defense LLC, a subsidiary of General Motors, delivers the first Infantry Squad Vehicles (ISV) — light and agile all-terrain troop carriers based off the 2020 Chevrolet Colorado ZR2 midsize truck architecture — to the U.S. Army on Oct. 27, 2020, in Milford, Mich. (GM Defense)

WASHINGTON — GM Defense delivered its first Infantry Squad Vehicle to the U.S. Army in an Oct. 27 ceremony at its proving grounds and production facility in Milford, Michigan, just 120 days after being chosen to build the new troop carrier.

The Army awarded the company a $214.3 million contract to produce 649 vehicles by the end of fiscal 2024. The service is planning to procure a total of 2,065 ISVs.

Designed to carry a nine-soldier squad, the ISV was specifically put together to be light enough to be sling loaded from a UH-60 Black Hawk and small enough to fit inside a CH-47 Chinook, to provide maximum flexibility for deployment.

GM’s design is based off the company’s 2020 Chevrolet Colorado ZR2 midsize truck and uses 90 percent commercial parts including a 186-horsepower, 2.8L Duramax turbo-diesel engine and performance race components. It also features a custom rollover protection system.

While the first low-rate initial production vehicles — 27 in total — will be built in Michigan, GM has a long-term plan to move its ISV manufacturing to Morrisville, North Carolina, where it is standing up a facility to manage its higher volume ISV production.

The Army first identified a need for a light infantry vehicle in 2015 when its most recent combat vehicle strategy was released, but nothing materialized until Congress forced the Army to launch the competition as part of the FY18 National Defense Authorization Act. The Army awarded $1 million contracts to three teams in August 2019 to develop offerings — GM Defense, a team of Oshkosh Defense and Flyer Defense LLC and an SAIC and Polaris team.

“One hundred and twenty days from contract award to delivery is a significant milestone, and I am very proud of the team for this accomplishment,” David Albritton, president of GM Defense, said in a statement. “We’re leveraging General Motors' engineering prowess and immense manufacturing capabilities to bring transformative solutions to the military vehicle market. Our initial success with the ISV shows our commitment to our customer and highlights our unique right to win in the military mobility market.”

GM Defense has a “very, very talented team," Albritton said during the ceremony, and “their innovation, attention to detail, flexibility when incorporating soldier feedback during testing and a magnitude of other factors helped us to win this ISV contract and gives me great hope for how we will tackle other pursuits in the future.”

The first vehicles will be going to the 1st Infantry Brigade Combat Team of the 82nd Airborne Division, but ultimately 11 IBCTs will be outfitted with 59 vehicles each under the first contract covering the 649 ISVs.

The vehicles are slated to go through tests in the coming year, including further analysis of its air-deployable capability, as well as verification the maintenance manuals are complete. The first unit equipped will take the ISV through an initial operational test and evaluation.

With the success of the ISV, GM Defense is setting its sights on other opportunities with the Army and other military services.

“We have a strong interest in the Joint Light Tactical Vehicle Program,” Albritton said. The Army is planning to re-compete for the JLTV and for new Humvees to round out the tactical vehicle fleet.

“If you look at the size and scale of this program, obviously, this is closer to a commercial-size vehicle, but as you step up in class and step up in weight, we believe we have a right to win in vehicles sizes of that size,” he added.

“That doesn’t limit us there, as well. There are only a few ground vehicle programs across the [Defense Department] right now, but we believe that other than doing a fully integrated vehicle like we do on ISV or what we potentially could do on JLTV in partnership with other companies, we can look at programs like the Advanced Reconnaissance Vehicle for the U.S. Marine Corps, or we can look at the Optionally Manned Fighting Vehicle," Albritton said. “But if you think about power and propulsion solutions, you think about light weighting, think about cybersecurity, there’s other types of capabilities that we can apply in partnership on a variety of platforms as well.”

GM spent several recent years helping the Army evaluate a hydrogen fuel cell vehicle using a ZH2 Chevy Colorado and the Army is now taking some renewed steps at getting after an electric vehicles in its fleet to include the pursuit of an electric light reconnaissance vehicle.

Next Generation Squad Weapons

Set to replace the M249 and M4A1, which fire 5.56 mm rounds, the NGSW under development with industry partners shoots 6.8 mm rounds, providing enhanced firepower to frontline warfighters.

During his presentation in the video, Maj. Wyatt Ottmar explained, “Near-peer adversaries continue to acquire and develop capabilities that counter army squad weapons and ammunition, reducing, and in some cases negating, our combat overmatch.”

The more powerful, versatile NGSW is a next-gen warfare weapon slated to hit the field in late 2022.
