Northrop Grumman's $200M contract targets cheap drone defense gap

The U.S. Army awarded Northrop Grumman a contract valued at more than $200 million to produce XM1211 High Explosive Proximity rounds, a 30mm shell designed to destroy drones at a fraction of the cost of missiles.

"Stingers, they're going to be more capable than guns, but they're also going to be more limited in terms of number," said Tom Karako, director of the Missile Defense Project at the Center for Strategic and International Studies.

The XM1211 is a 30x113mm round integrated with a proximity sensor that detonates when close enough to a target, sending fragmentation to neutralize it without requiring a direct hit. The round is compatible with Northrop Grumman's XM914 and M230LF Bushmaster Chain Guns. At roughly $2,250 per round, five rounds would cost about $11,250 to down a single drone, according to Steven Sawyers, a former ammunition technician at NATO's logistics support and procurement agency. That compares with $430,000 for a Stinger missile, $100,000 to $125,000 for a Coyote drone interceptor, and $1 million for an AIM-120 air-to-air missile, per CSIS estimates. Iran's Shahed-class drones cost roughly $30,000, while small quadcopters run between $1,500 and $5,000.

The cost asymmetry has become one of the most pressing problems in modern warfare. In the Middle East, the U.S. and Gulf nations have relied on helicopters and aircraft guns to shoot down Iranian drones but also on expensive air-to-air missiles that are harder to produce in volume. The Madis system, tested by U.S. Marines in the Philippines in April, combines two Joint Light Tactical Vehicles — one mounted with an RPS-62 radar and the other carrying Stinger missiles — along with electronic warfare jamming and the 30mm cannon. The mobility of the system is particularly important for the Marines as they prepare for potential conflict in the island environments of the Indo-Pacific.

Northrop Grumman and the Army's Project Manager Maneuver Ammunition Systems rapidly developed the XM1211 to meet an urgent materiel release in 2021 and are now accelerating production capacity to meet rising domestic and international demand. The company will manufacture the rounds at its facilities in Plymouth and Elk River, Minnesota; the Allegany Ballistics Laboratory in West Virginia; and the Radford Ammunition Plant in Virginia. L3Harris, which makes fuzes for 30mm ammunition, is also rapidly scaling to meet growing demand, a company spokeswoman said. "Proximity fuzes are precision electromechanical devices, and the lines that build them at scale are few," Sawyers said.

The last major push for cost-effective counter-drone ammunition came after the 2021 urgent materiel release, when the Army and Northrop Grumman accelerated development from concept to fielding in under 18 months. Since then, drone warfare has expanded dramatically — Russia's use of Iranian Shahed drones in Ukraine and Houthi attacks on Red Sea shipping have demonstrated that cheap unmanned systems can challenge forces equipped with million-dollar missiles. The Pentagon's 2026 budget request included a 31 percent increase for counter-drone systems, reflecting the shift in procurement priorities.

For the Marines who tested the system in the Philippines, the calculus is straightforward. During the drill, they fired dozens of inert training rounds at fixed-wing and rotor targets, using the 30mm cannon for larger drones and the smaller machine gun's higher rate of fire for smaller targets. "There's just so many out there, you don't know exactly what you're going to be fighting," said Staff Sgt. Noah Konie. "You hope that your intelligence is good, but you just go out there with everything that you got, hoping for the best."
