Marines Rushing To Equip Amphibious Combat Vehicles With New Anti-Drone Jammers

The U.S. Marine Corps is buying Anduril Pulsar-L electronic warfare jammers to meet an urgent operational need to better protect its 8×8 wheeled Amphibious Combat Vehicles (ACV) from drones. This is part of broader efforts the service is pursuing to boost the ACV’s defenses against uncrewed aerial attackers, as well as incoming anti-tank guided missiles and other threats. Drone threats are real now and have notably sidelined even the most advanced heavy armor in Ukraine.

Marine Corps Systems Command (MARCORSYSCOM) announced it had awarded a sole-source deal to Anduril, valued at $15,711,445.50, for an unspecified number of Pulsar-Ls, yesterday. This follows a statement of intent the Command put out last month. Anduril first unveiled Pulsar-L, a lightweight addition to its larger Pulsar family of electronic warfare systems, in April 2025.

The Marine Corps had 150 baseline personnel carrier variants of the ACV (or ACV-Ps), as well as 21 command-and-control ACV-C versions, in inventory as of April 2026. The default armament for ACV-P currently is just a single .50 caliber M2 machine gun in a remote weapon station on top of the hull. The service’s goal is to eventually acquire 389 ACV-Ps and 33 ACV-Cs, as well as 152 ACV-30s with new 30mm cannon-armed turrets and 34 ACV-R armored recovery vehicle variants. The ACV family has already supplanted the Marine Corps’ previous fleet of tracked Assault Amphibious Vehicles (AAV).

“The Anduril Pulsar-L system is a platform-integrated omni-directional SK C-UAS [soft-kill counter-uncrewed aerial systems] with a combined sensor/jammer package that detects, tracks, identifies, and defeats radio frequency-dependent Group 1 and Group 2 Unmanned Aerial Systems (UASs),” MARCORSYSCOM wrote in a justification for the sole-source contract, which was also released yesterday. “Additionally, the system provides counter positioning, navigation, and timing capabilities.”

The U.S. military definition of a Group 1 drone is any design weighing up to 20 pounds, that is able to fly up to an altitude of 1,200 feet, and that can reach speeds of up to 100 knots. Group 2 is the next tier up, encompassing types with gross weights between 21 and 55 pounds, that can get up to an altitude of 3,500 feet, and hit top speeds of up to 250 knots. Kamikaze drones and other small weaponized types that fall into Groups 1 and 2 are used on a daily basis in Ukraine to attack armored vehicles, as well as unarmored vehicles and personnel. These are threats that have been steadily expanding to other hotspots globally, and that we will come back to later on.

Furthermore, “the Pulsar-L is the only solution capable of being mounted on the ACV to provide a mobile and organic means to effectively and simultaneously execute the entire kill-chain against hostile UASs in the deployed land and mai·itime/littoral environment while not exceeding the limited ACV space, weight, and power claim allotted to the SK C-UAS solution,” according to MARCORSYSCOM. “This will provide the ACV with an essential defensive capability, directly contributing to increased survivability and force protection while not sacrificing the mobility and operational tempo of the ACV.”

Pulsar-L is already “in use by the Special Operations Command due to the system’s low weight, proven performance in engaging multiple UASs, and simultaneous execution of the full kill-chain while static or on the move,” the justification document adds. “Additionally, it is the only known commercially available system that meets the minimum requirement to rapidly identify and respond to emerging UAS technologies and tactics without frequent updates to predefined threat data libraries. The Pulsar-L is the only solution that uses machine based learning to continually adapt to these ever-changing threats without requiring vendor updates, allowing the warfighters to continually be effective in the fight.”

The latter point here is a particularly important consideration for electronic warfare systems, in general, which need to be able to accurately detect, categorize, and respond to different waveforms to be most effective. The emergence of new waveforms, as well as changes to how existing ones are emitted, together with new tactics, techniques, and procedures, can all negatively impact a system’s performance. Historically, the process of responding to those developments with updates to built-in threat libraries has been lengthy and complex. The conflict in Ukraine has shown that the cycle of new developments in the electromagnetic spectrum and then the need for new countermeasures can be regularly measured in weeks.

The U.S. military has been heavily investing in so-called cognitive electronic warfare capabilities to help automate and otherwise accelerate various aspects of this process. The ability of a particular electronic warfare suite to adapt autonomously in real-time, even in the middle of operations, has been viewed as the absolute ‘holy grail’ of this concept, which you can read more about here. How exactly Pulsar-L leverages machine-learning and artificial intelligence to this end, and the speed with which it can adapt to changing threats, is still not entirely clear.

Regardless, “there is an unusual and compelling need for the rapid deployment of SK C-UASs to forward-deployed ground units as Marines currently lack the ability to conduct self-defense against emerging UAS threats,” the justification document stresses. “Failure to deliver this capability places Marines at unnecessary risk, potentially leading to mission failure and loss of life, and hampers the Government’s ability to keep them safe during forward deployments.”

MARCORSYSCOM’s justification for the sole-source deal to Anduril does not otherwise elaborate on the urgent requirements that drove the deal, which it says were only formalized on April 7. That is notably roughly a week after the United States and Israel first launched major combat operations against Iran, which is a prolific developer and user of various tiers of weaponized drones. There is no explicit confirmation of any link, but Iranian drones, as well as missiles and other capabilities, have been a real threat to U.S. forces in the region. We have also just gained more insights recently into how forward-deployed Marine Corps elements contributed to those operations. Counter-drone capabilities would also be especially critical in any future amphibious landing operation, wherever it might occur.

All that being said, threats posed by armed Group 1 and 2 drones are not at all limited to Iran and the Middle East, nor are they new. They are only likely to become a more ubiquitous feature in the hands of nation-state armed forces and non-state actors in conflict zones globally as time goes on. The nature of these threats is also expanding significantly in scale and scope, especially when it comes to more automated targeting capabilities, thanks heavily to the increasing democratization of AI-driven technologies, something TWZ has explored in depth in the past.

A number of other significant developments in this arena have emerged from the conflict in Ukraine, where electronic warfare systems are heavily employed against drones. This includes the introduction of physical fiber-optic control links that cannot be jammed, as well as the use of mesh-like and often ad-hoc networks to increase resiliency.

The fighting in Ukraine has also underscored the threat that even small kamikaze drones pose to armored vehicles, including types that are far more heavily protected to start with than the Marine Corps’ ACVs. As mentioned, Ukrainian forces have been sidelining their M1 Abrams and other main battle tanks in the face of constant drone attacks.

MARCORSYSCOM’s justification for the Pulsar-L order makes clear that this is just one part of a larger plan to boost the ACV’s defenses.

“Marine Corps program of record for SK C-UAS is planned to initiate in FY27,” the document mentions toward the very end. “The components of this future program will be procured through full and open competition as it is expected that advanced non-kinetic and SK defeat technologies should be mature by this time.”

Marine Corps officials have also talked in the past about integrating active protection systems (APS), which could be blended together with C-UAS capabilities, and other defensive features to the service’s ACV fleet.

“We’re constantly looking at what the next generation of APS is and how we can get that onto the [ACV] platform in a lightweight form factor,” Chris Melkonian, the Marine Corps’ Program Manager for Advanced Amphibious Assault (PM AAA), told TWZ and other attendees at the annual Modern Day Marine exposition in April.

Improved “situational awareness, that’s kind of a gateway to counter-UAS, in terms of the ability to sense your environment,” Melkonian also highlighted at that time. “Take all that video on board and then be able to feed that into [a] counter-UAS system.”

Additional “overhead protection right now is a critical thing that we’re working on right now for this platform,” he added. The practice of adding on anti-drone armor screens on armored vehicles (and now other platforms), especially to protect against top-down attacks, first emerged in Russia in the lead-up to the all-out invasion of Ukraine in 2022. However, the installation of this kind of so-called ‘cope cage’ type armor has now become a global trend, including in the U.S. military.

The U.S. Marine Corps is also pressing ahead with a larger vision to field several tiers of counter-drone capabilities at all levels of its forces, to better protect everything from static installations at home and abroad right down to individual squads.

When it comes to the Marine Corps ACV fleet, the rush order for Pulsar-Ls is an important new step in boosting those vehicles’ defenses against threats that exist now. At the same time, drones are increasingly calling the role of armored vehicles in future conflicts into question.
