General Dynamics Land Systems (GDLS) has offered the first official look at its proposal to replace the U.S. Army’s Bradley Fighting Vehicles, called the Wolf. The Wolf is one of two designs competing to become the Army’s future XM30 Mechanized Infantry Combat Vehicle (MICV). Just earlier today, we published a detailed update on the XM30 competition, including new information about both entrants and the Army’s testing plans, which you can find here.
GDLS is showing the one-eighth-scale model of Wolf, seen at the top of this story and made by a company called KiwiMill, at the Association of the U.S. Army’s (AUSA) main annual convention, at which TWZ is in attendance. Wolf is facing off head-to-head against a version of the Lynx from Germany’s Rheinmetall, supplied via the company’s U.S. subsidiary, American Rheinmetall.
It has already been established that Wolf is a further evolution of the GDLS’ Griffin III design, which was first shown publicly at AUSA back in 2018. Griffin III was derived from the ASCOD 2 infantry fighting vehicle, for which Spain was the launch customer, and which is now entering service in Latvia. The U.S. Army’s now-cancelled M10 Booker ‘light tank’ and the British Army’s much-troubled Ajax are also members of this broader family of armored vehicles.

The design of the Wolf, at least based on the model, is substantially different from the earlier Griffin III demonstrator.
Wolf’s turret has a broader, flatter, and overall more streamlined shape, which is in line with its remotely-operated design. There is just a single sensor turret on top, along with space for a forward-looking sensor suite to the left of the main 50mm cannon. What may be apertures for additional sensors or other systems are seen elsewhere along the front and sides of the turret. It also has more launchers for smoke grenades around the front edges compared to the Griffin III.

Compared to the Griffin III, the Wolf’s hull has also been much revised, including the elimination of a traditional driver’s hatch in front of the turret ring. The vehicle’s commander (who also acts as the gunner) and driver sit side-by-side deeper inside the hull. Up to six passengers can ride in a compartment further at the rear. For comparison, the Bradley has a crew of three, as well as the ability to carry six passengers.
The Wolf’s hull also features side skirts that were not found on the Griffin III demonstrator. A different style of tracks is also depicted on the model. The picture of the model that GDLS shared shows sensors facing outward from a position on the side of the hull toward the front, as well. This makes sense, as the design features a distributed camera system to offer a full 360-degree view of the outside to personnel riding within, the broad benefits of which you can read more about here.

“Because we have a reduced crew from the Bradley [which has a commander and gunner in turret] there has to be greater efficiency in how those soldiers execute their tasks,” Geoffrey Norman, GDLS’ director for U.S. Strategy & Growth, previously noted to TWZ. “The software and menu logic are very intuitive.”
Next-generation fire control, sensor, and networking/communications capabilities, as well as improved active and passive defenses, are key requirements for the XM30 program. Both Wolf and American Rheinmetall Lynx-based designs have built-in launchers for loitering munitions, with GDLS having chosen to integrate AeroVironment’s Switchblade 300 more specifically. What we have seen on the Wolf model so far does not appear to explicitly show this particular feature.
Wolf and Lynx both also feature hybrid-electric propulsion, which will bring various benefits, especially in terms of fuel economy and electrical power generation, compared to the diesel-engined Bradley. When it comes to the boost in on-board electrical power, “the emphasis from the Army has really been about having margin on the vehicle for future [system] requirements – directed energy, counter-UAS systems, or fill-in-the-blank,” GDLS’ Norman has also told us in the past.

As it stands now, both GDLS and American Rheinmetall have delivered prototypes of their respective designs to the Army, with initial testing having been conducted at Aberdeen Proving Ground in Maryland. Soldier touchpoints and field evaluations are now set to occur at Fort Hood in Texas between February and March of next year. You can read in more detail about both entrants in the XM30 competition and what is known about their features in our past reporting here.

In the meantime, we have now gotten clear views of both designs vying to become the Army’s XM30 replacement for the venerable Bradley.
As General Dynamics Land Systems (GDLS) and American Rheinmetall display their wares at the Association of the U.S. Army’s (AUSA) main annual symposium this week, the contractors have delivered their XM30 Mechanized Infantry Combat Vehicle (MICV) prototypes to the Army for testing and soldier evaluation at two locations to meet a slightly altered test program.
The XM30 program is the U.S. Army’s latest effort to replace its fleet of Bradley Fighting Vehicles. As TWZ noted in a recent article, the Army had planned to test a number of the eight prototypes that each competitor is required to provide during a regular rotation at the sprawling National Training Center (NTC) at Fort Irwin in California next spring.

According to both GDLS and American Rheinmetall, each will now deliver seven prototypes to the Army’s 1st Brigade Combat Team, 1st Cavalry Division at Fort Hood, Texas. There they will undergo a soldier touchpoint and field evaluations, which could wrap up in the February-March 2027 timeframe. No rotation to Fort Irwin is now envisaged.
TWZ spoke with executives from both XM30 competitors and reached out to the Army ahead of AUSA. Geoffrey Norman, GDLS’ director for U.S. Strategy & Growth, said that three of its prototypes are already at Fort Hood undergoing safety checks before being put in soldiers’ hands for evaluation. The company’s offering is called Wolf, which evolved from its Griffin III, which in turn was derived from the ASCOD 2 infantry fighting vehicle.

American Rheinmetall, a U.S. subsidiary of Germany’s Rheinmetall, has put forward a version of the extended Lynx family for the XM30 competition. The company has delivered one of its prototypes to Fort Hood, according to the company’s senior vice president of programs, Jim Schirmer. Another one is at the Army’s Joint Forces Training Center at Camp Shelby, Mississippi, where the company is doing its own internal testing. Its remaining vehicles are being assembled in Slidell, Louisiana.

Both companies delivered their very first XM30 prototypes to Aberdeen Proving Ground in Maryland in late August, along with an additional hull and turret each for ballistics testing. Over the last month-plus, the Army has gained preliminary experience with the MICVs at Aberdeen.
Early Feedback
GDLS’ Wolf has already put its 50mm cannon into action on the live-fire range at Aberdeen, according to Norman. It has also been put through some portion of automotive functional testing, and Norman says GDLS is getting “good feedback” on both. He adds that the Wolf’s 32-speed SAPA transmission and composite rubber track (CRT) have been well received, with favorable comparisons to the ride-quality/comfort of the Bradley.

Schirmer says that the Lynx has also received positive early feedback, particularly during a late September demonstration for congressional staffers and Army VIPs at Aberdeen. Passengers praised its two-man crew station layout, the roominess of its six-man squad compartment and its air conditioning system.
Schirmer reflected on the value of greater environmental comfort for squad members who sweltered inside the Bradleys used in Iraq. He recalled that, “When it was 125 degrees outside in Iraq with additional solar loading, inside the Bradley the temperature got to 138 degrees. It actually felt refreshing to step out into the Iraqi air.”
Both prototypes are larger than the 40-ton Bradley with correspondingly heavier combat weights in the 50-ton region. Both feature an XM913 50mm automatic cannon as their main weapon, a welcome increase in firepower compared to the 25mm M242 on the Bradley.

Schirmer acknowledged that American Rheinmetall has found some small bugs in its first Lynx prototype at Aberdeen. “We spent a fair amount of time swapping hardware and making adjustments to make sure it was ready [for the VIP event].”
Crew Efficiency and Room for Growth
Both competitors have emphasized the greater efficiency and capacity to add weapons systems and sensors to their MICVs compared with the Bradley. Each has a two-man crew as opposed to the Bradley’s three-man complement. XM30 commander-gunners operate from below the turret as opposed to in it with the Bradley. The new configuration puts a premium on crew situational awareness and task management.
Wolf and Lynx feature side-by-side crew stations for the vehicles’ commander and driver, an aviation-style layout conducive to enhanced crew coordination. Both firms have placed considerable emphasis on intuitive user interfaces with multiple displays and menus with specifically designed symbology and text, as well as ergonomically optimized controls. In addition to higher resolution and longer range gunsight displays, each prototype offers its crew and the squad it carries a 360-degree outside view provided by cameras placed around the vehicle.

“Because we have a reduced crew from the Bradley [which has a commander and gunner in turret] there has to be greater efficiency in how those soldiers execute their tasks. The software and menu logic are very intuitive,” Norman affirms.
Left and right crew positions are identical, so functions can be performed by either crew member. In the Wolf, the driver sits to the left in most cases with the commander on the right. GDLS has drawn lessons from soldier touchpoints with early prototypes of the M1E3 Abrams tank (for which it is the prime contractor), which Norman says shares its graphical user interface with Wolf.

The Lynx crew compartment features three configurable displays, with a large center display with a common operating picture/map with visual feeds from airborne uncrewed aerial systems (UAS). “You can shoot the gun from the left or right, you can drive the vehicle from the left or right,” Schirmer confirms.
A camera for the Lynx commander’s independent weapons station atop the vehicle with its own sight and machine gun can be pulled up for view by the crew, which can toggle between it and the main weapons sight. Lynx operators have the ability to turn off certain information presentations in their displays for better focus on a particular task.
The effort to improve efficiency for smaller armored vehicle crews was highlighted last week as GLDS announced that it has partnered with Primordial Labs to bring artificial intelligence (AI) voice control to its combat vehicles, ranging from the M1 to the XM30. American Rheinmetall has likewise developed its own AI assistant for Lynx crews, Schirmer confirms. He characterizes it as a “third crewman” helping two soldiers do the work of a trio.
The video below shows Primordial Labs’ voice control technology being used to operate a quadcopter-type drone.
Cooling has become an issue for the Bradley, which, like all armored vehicles, essentially encloses its powerplant and electronics in a box with no airflow. Heat from the drivetrain creates a detectable thermal signature, particularly with the Bradley’s right-front exhaust exit.
Both Lynx and Wolf feature hybrid-electric drivetrains with silent-watch capability, which can temporarily reduce their thermal signatures. Each features rear-exhaust exits, alleviating front-quarter heat plumes.
According to Schirmer, the Lynx cooling stack (which sits adjacent to its powerplant forward in the hull) offers increased cooling for the engine and battery packs while improving the interior environment for heat-sensitive electronics. It facilitates systems growth and greater power consumption.
Wolf has its engine cooling in the rear of the vehicle behind the track. Norman says GDLS specifically engineered its placement so cooling paths to the rear of the hull don’t impinge on passenger space inside. All Wolf systems are designed with a 10 percent growth margin, he adds.
The hybrid drive systems and electronics that both XM30s use will have to resist the increasing threat from adversary directed energy. Electronic attack in the form of tactical electromagnetic pulse, laser targeting of external sensors/apertures, and weaponized electromagnetic interference constitutes a growing threat to weapons systems and basic mobility.

Both contractors expect the Army to stringently test their prototypes’ electromagnetic vulnerability. “I think they’ll nail our vehicles with the best [electromagnetic attack] that adversaries have and if they identify any weaknesses, we will correct those,” Norman says. He points to Aberdeen’s large, sophisticated anechoic chamber as a place where both MICVs will eventually spend considerable time.
American Rheinmetall has its own electromagnetic interference (EMI) requirements for vehicle sensors and communications, according to Schirmer. The Army also has an in-depth understanding of the threats and explicit EMI requirements, he says. “We’re pretty comfortable that our system meets those, but actual EMI testing will take place later in the test program.”
Expanded capacity for exportable power is another growth area for XM30. The prototypes’ hybrid powerplants feature large battery packs that can offer exportable power to potentially help the Army with its serious battlefield circulation of electricity (BCoE) problem. The ever-increasing array of soldier-worn electronic devices, electrically-powered small drones and sensors has created an electricity supply deficit as well as battery weight and availability issues.
Wolf produces “a lot more power than it needs,” Norman asserts. As a result, upgrades to its alternators, starter-generators and high-voltage batteries won’t be needed in the foreseeable future. The exportable power emphasis is on the passengers, he explains.
Wolf’s internal power distribution provides significant charging power to the squad compartment in the back, where each member can charge devices and get access to data. The charge-ports they use are cyber-hardened to prevent plug-in exploits.
External exportable power is surprisingly not a priority for the MICVs, according to the contractors. Wolf can offload power via a standard NATO power port (as can Lynx) and other interfaces, Norman says, but “we’re not seeing XM30s in use-cases where they’re used to power command posts or other things. The emphasis from the Army has really been about having margin on the vehicle for future [system] requirements – directed energy, counter-UAS systems or fill-in-the-blank.”
Counter UAS and Fill-in-the-Blank
A September report from the Congressional Research Service cited a potential XM30 oversight issue for Congress, contending that it is not clear if the MICV will have an organic counter-UAS capability. Given the obvious threat of aerial drones to armor as seen in Ukraine, the apparent lack of a requirement for integrated CUAS appears glaring.
We reached out to the Army’s PAE Maneuver Ground and PM XM30 regarding CUAS for XM30 but received no response as of this writing. Both American Rheinmetall and GDLS believe the Army will undertake its own search and competitive testing to identify a CUAS system for XM30 that it will require the vendors to integrate at some future point.
GDLS’ Norman calls CUAS “fundamental” to the viability of armored vehicles on the modern battlefield. He thinks the Army’s approach of making sure CUAS infrastructure (power/data/physical hookups) is in place on XM30 while evaluating potential systems on its own for rapid integration is wise. He adds that GDLS is working with “expert partners” in the CUAS space to be ready to add the capability.
Intriguingly, American Rheinmetall’s Schirmer says that Lynx already has some counter-UAS capability, which he declined to disclose.
Both XM30s have the ability to launch loitering munitions – Wolf will employ Aerovironment’s Switchblade 300 and Lynx will carry a version of Raytheon’s Coyote Block 3 – but their makers currently have no specific plans for other integrations, though each says it can adapt multiple systems.

TWZ previously noted that the Army envisions XM30s acting as controllers for unmanned ground vehicles. GLDS’ Wolf has an in-house interface to control UGVs (and UAVs) from inside the vehicle, which was demonstrated to the Army over a year ago, according to Norman. Its open software architecture allows for integrating a different control suite if the Army desires.
American Rheinmetall has “not attempted to control an unmanned ground vehicle yet, but the architecture is so similar it would really be just a software modification to get there,” Schirmer says. The company would likely use a mix of its own and UGV provider software.
The Lynx itself can be remotely operated via a tablet that a dismounted crew can employ. While outside the vehicle, soldiers can also remotely use the tablet to see what the vehicle is seeing or to pull up maps for planning, Schirmer explains. American Rheinmetall has yet to finalize and demonstrate the capability, but it appears an appropriate feature for a design that stretches back to the Army’s Optionally Manned Fighting Vehicle (OMFV) program.
Recent Army experimentation with small vehicle-toted UGVs on Bradley suggests a capability that could migrate to XM30. Wolf can accommodate “marsupial UGVs” like the Swambotics AI Fire Ants fitted on a 1st Cavalry Division M2A4 Bradley, but Norman points out that small UGV carriage is not part of the requirements for the first iteration of XM30.
A U.S. Army 1st Cavalry Division M2A4 Bradley IFV was spotted carrying five Swarmbotics AI FireAnt anti-armor UGVs on its side storage racks.

American Rheinmetall has not specifically planned for carrying UGVs on its MICV, but Schirmer asserts that if a Bradley can carry them, Lynx certainly can. Whether it may be able to recharge them during transit is a question that will depend on future Army desires, he says.
Fit for Purpose
Given threats from increasingly capable drones and guided anti-tank missiles, questions as to whether XM30 or other armored vehicles remain relevant on the modern battlefield have persisted for several years.
Such concerns arguably drive the discussion of value-added capabilities for XM30 – from advanced sensors and networking/communications to the ability to deploy and control UGVs/UAVs and the potential BCoE benefits of the platforms.
GDLS’ Norman refers to Wolf as “software with a vehicle around it”, noting that GLDS is “continually dropping new software” into its XM30 on a weekly basis to add capability.

However, American Rheinmetall’s Schirmer reminded us that the traditional armored transport mission is still the overarching role of XM30.
“The purpose of [Lynx] is really to carry infantrymen around the battlefield…to move them faster than they can walk on foot, to protect them in transit from threats – drones, anti-tank guided missiles, from artillery fire – and to [provide] fires support.”

The tension around XM30 survivability versus cost is reflected in the Army’s loose commitment to the new MICV program. Despite having muted fielding of an XM30 by 2029, Brig. Gen. Troy Denomy, Program Acquisition Executive of Maneuver Ground, told Breaking Defense that if no clear winner emerged from the upcoming test and evaluation, “then it may be worth not selecting at that point.”
The ambiguity tees up the question of where a 50-ton armored vehicle fits into the potential Pacific fight that the U.S. military is focusing on. It’s a difficult question for the Army and for the XM30 contractors.
American Rheinmetall’s Schirmer took a stab at answering. He points out that there are large islands and other landmasses in the Pacific (like the Korean Peninsula) where a MICV could be employed. However, he acknowledges that it is less likely to be used in an island campaign.
“It still has a role, though it’s less obvious what that would look like than in Europe or the Middle East.”
With testing and evaluations set to ramp up at Aberdeen Proving Ground and Fort Hood, we may soon learn which XM30 prototype is the Army’s obvious choice.
