Programmable Airburst Cannon (30/35/40mm)
Vehicle- or pedestal-mounted autocannon firing programmable airburst ammunition (Oerlikon AHEAD, Bushmaster 30×113, XM1211). Each round dispenses ~150 tungsten subprojectiles at a programmed range, forming a lethal cloud, no direct hit required. Solves the 'magazine depth' problem of missile-based C-UAS at one-tenth to one-hundredth the cost per engagement.
How It Works
A muzzle programmer inductively writes the time-of-flight to the round as it leaves the barrel. The fuse counts down and bursts the projectile a few meters in front of the target, releasing tungsten subprojectiles into the drone's flight path. Cued by an integrated radar/EO fire-control system. Effective against Group 1–3 UAVs and one-way attack munitions like long-range strike drones.
Technical Specifications
Advantages
- + Massive magazine depth vs. missile interceptors (hundreds of rounds)
- + Cost per kill 10–100× cheaper than MANPADS or kinetic interceptor missiles
- + Effective against long-range strike UAVs and one-way attack drones
- + Works against fiber-optic and autonomous drones (no RF dependency)
Disadvantages
- − System cost is high (millions of $) even if rounds are cheap
- − Range limit: does not engage standoff loitering munitions
- − Falling shrapnel hazard: restricted use over friendly/civilian areas
- − Requires high-quality radar cueing to be effective
Tactical Deployment Tips
- ▸ Position to cover known long-range strike-drone ingress corridors and approach lanes
- ▸ Integrate with passive radar / RF detection for early cueing
- ▸ Combine with interceptor missiles for layered engagement (gun for cheap mass, missile for outliers)
Limitations & Vulnerabilities
- ⚠ Falling debris makes urban use difficult
- ⚠ Cannot reach high-altitude HALE/jet UCAV threats

⚠ How Adversaries Defeat This System
Active enemy adaptations observed in the field, distinct from passive limitations above
- ▸ Saturation salvos exceeding rate-of-fire and slewing limits
- ▸ Low-altitude terrain-masked approaches below radar horizon
- ▸ Standoff munition release outside engagement envelope
