Northrop Grumman Raid Hunter

History

Northrop Grumman Raid Hunter is a developing 50 mm gun-based air-defense system intended to counter massed and mixed aerial threats, including uncrewed aerial systems, drone swarms, and cruise missiles. The system combines a high-rate-of-fire Bushmaster Chain Gun, precision-guided 50 mm ammunition, and a networked system controller.

Northrop Grumman positions Raid Hunter as a short-range layer within integrated air and missile defense architectures. Its modular design is intended to support rapid deployment and several installation configurations while allowing multiple systems to operate through a networked command-and-control architecture.

Raid Hunter was introduced under its current name in August 2026. It had previously been identified as Northrop Grumman's 50 mm Gun-Based Air Defense, or GBAD, system.

Development

Northrop Grumman developed Raid Hunter in response to the growing requirement to defend against large aerial raids that can combine numerous uncrewed aircraft with other threats. The design emphasizes a high rate of fire, guided ammunition, deep ammunition capacity, rapid reloading, and networked operation rather than reliance on a small number of missile interceptors.

The company describes Raid Hunter as platform-agnostic and modular. The initial concept uses a palletized configuration that can be transported aboard C-130 aircraft. Northrop Grumman also plans vehicle-mounted and container-based configurations.

Raid Hunter forms part of Northrop Grumman's Raid Defense Solutions portfolio, which combines kinetic effectors with networked command and control, sensor fusion, and other counter-UAS and air-defense capabilities.

Testing

Northrop Grumman stated in 2026 that it was working with government and allied partners to mature the system. Testing was planned throughout 2026 to validate counter-UAS and air-defense performance and support accelerated fielding. Publicly available information does not establish that Raid Hunter is operational.

Detailed public specifications for the system's sensors, tracking performance, engagement range, magazine capacity, reload time, probability of kill, and external interfaces had not been disclosed at the time of its introduction. Contemporary reporting also described the concept as being years from delivery, reinforcing its status as a developing capability rather than a fielded system.

Design

Weapon system

Raid Hunter is centered on a 50 mm Bushmaster Chain Gun. Northrop Grumman describes the weapon as providing a high rate of fire suitable for engaging numerous aerial targets during a massed raid. The system is intended to combine the gun with deep ammunition capacity and rapid reloads so that it can sustain repeated engagements.

The gun fires precision-guided 50 mm ammunition. Northrop Grumman describes the ammunition as steerable and capable of making multiple in-flight maneuvers. This guidance is intended to improve effectiveness against small, maneuvering aerial threats compared with conventional unguided cannon ammunition.

Command and control

Raid Hunter uses a networked, interoperable system controller based on Northrop Grumman's AiON command-and-control software. The architecture is intended to coordinate engagements and allow the weapon to operate as part of a broader layered air and missile defense network.

Multiple Raid Hunter systems are intended to function together as an integrated network. The networked architecture is also intended to support sensor fusion and coordinated responses to complex raids containing different types of aerial threats.

Mobility and configuration

The system uses a modular and platform-agnostic architecture. Northrop Grumman says the palletized configuration is designed for rapid transportation aboard C-130 aircraft, allowing the system to be moved between defended locations.

Vehicle-mounted and container-based configurations are planned. These proposed arrangements are intended to expand deployment options, but they should not be considered operational variants until their development and fielding are confirmed.

Program status

Raid Hunter remained under development in 2026. Northrop Grumman planned continued testing during the year while working with government and allied partners to mature the design and support accelerated fielding.

The company has presented the system as a short-range component of layered defense rather than a standalone solution for every aerial threat. Its intended target set includes uncrewed aerial systems, drone swarms, cruise missiles, and other high-volume aerial threats.
