"Skies Are Changing": Northrop Grumman Unveils Chain Gun To Defend Critical Infrastructure From Drone Swarm Attacks

Our view of the missing air-defense layer around data centers and other critical infrastructure emerged in late January, roughly one month before the US-Iran conflict, when we published "Explosion in AI Data Center Buildouts Will Demand Next-Gen Counter-Drone Security."

That theme was validated shortly after the war began, when Iran targeted multiple data centers with Shahed-series one-way attack drones, which generally fall within the Group 3 category. The strikes marked one of the clearest demonstrations of how low-cost, long-range drones could threaten the physical infrastructure underpinning the AI economy.

The conflict has fundamentally changed the threat assessment surrounding high-value civilian assets and has become a matter of general consensus among military leaders and politicians, as well as the military-industrial complex and many defense startups.

We just happened to be one month ahead of that shift in consensus.

Now, defense giant Northrop Grumman has unveiled Raid Hunter, a 50mm gun-based air-defense system designed to protect not only military bases but also critical infrastructure from drone swarms, cruise missiles and other aerial threats.

Raid Hunter combines the company's Chain Gun technology with precision-guided 50mm ammunition and a networked battle-management controller. Northrop said the high rate of fire, deep magazine and rapid reload capability offer a more economical response than launching million-dollar interceptor missiles at $20,000 drones.

Highlights of the new kinetic interceptor:

• Raid Hunter combines proven Chain Gun technology, precision-guided 50mm ammunition and a networked, interoperable system controller to deliver powerful protection against high-volume, mixed-threat aerial raids. It is designed to defeat a range of aerial threats, including high-priority cruise missile threats, unmanned aerial systems (UAS) and other advanced threats.
• Raid Hunter's guided 50mm ammunition, combined with a high-rate-of-fire Chain Gun, delivers lethal, cost-considerate engagement with deep magazines and fast reloads, tackling the economic challenge of massed swarming threats.
• Raid Hunter is built to deploy with speed and flexibility through a modular design for rapid transportation on the C-130, with future vehicle-mounted and container-based variants planned.
• Raid Hunter is the latest product of Northrop Grumman's continued investment in advanced counter-UAS and air-defense technologies designed to meet evolving operational requirements and emerging battlefield threats.
• As part of the company's C-UAS integrated air- and missile-defense portfolio, the system supports layered defense architectures to protect critical assets across a range of operations.

The big challenge now shifts to series production capable of meeting the soaring demand from bases, data centers, refineries, power plants, substations, and you name it...
