Marine Corps picks Bullfrog for L-MADIS, putting a gun on a jamming truck

Allen Control Systems' autonomous turret joins L-MADIS under a prototype agreement worth about $6.2 million, adding bullets to a counter-drone platform that has run on jamming.

The Marine Corps has selected Allen Control Systems' Bullfrog autonomous weapon station under its Ground Based Air Defense program, the Austin company said Monday. Bullfrog goes onto the Light Marine Air Defense Integrated System, the Corps' most expeditionary counter-drone platform, through a prototype Other Transaction Agreement.

Breaking Defense put the initial award at roughly $6.2 million, Defence Blog relayed. Janes described the agreement as undisclosed in value and noted that ACS did not answer its questions on which Bullfrog variant is going onto the vehicle.

L-MADIS rides on two Polaris MRZR all-terrain vehicles, one for command, the other carrying an electronic-warfare suite built to jam and disrupt hostile drones, according to Army Recognition. Bullfrog bolts a gun onto that. The platform has been EW-first, and jamming does nothing to a drone flying an autonomous route with no radio link to break. The turret covers that gap.

The hardware is a mount, not a new weapon. It takes an M240 machine gun and turns it into a detect, track and engage system: 300 pounds without ammunition, 7.62x51mm NATO, up to 850 rounds a minute, per the company. The sensor suite is fully passive, cameras and processing rather than radar, so the station does not radiate a signature for an adversary to hunt. A human still has to approve every engagement. Range figures diverge. Defense News gave the M240 variant a maximum effective range of nearly half a mile; Janes cited 800 meters from the company's website; Defence Blog wrote up to 1,500 meters depending on variant.

ACS claims a cost-per-kill as low as $10. The reference point: Iranian Shahed drones run about $35,000 while some U.S. interceptors cost around $4 million, Defense News wrote.

Bullfrog is already deployed with the Army and Navy and validated through Joint Interagency Task Force 401, the Pentagon's counter-drone acquisition unit, the company stated. ACS holds export contracts with South Korea and the UAE, plus a co-production memorandum with Romania.

In June the company raised $200 million at a $2.2 billion valuation. This is the procurement step that money was raised to win. The Corps is requesting about $1.27 billion for Ground Based Air Defense in its fiscal 2027 budget, and the $6.2 million prototype buys a seat at it.
