The M64 HYDRA is a 64‑barrel rotary Gatling cannon chambered in 32×173mm, purpose‑built for counter‑drone and anti‑swarm defense. Its barrels are arranged in 7 concentric rings (8, 16, 24, 32, 48, 56, 64 cumulative) with a precise 1‑inch center‑to‑center spacing on every ring. A unique gear‑driven mechanical loading system with rack‑and‑pinion rammer pushes each round into the chamber with absolute reliability. The weapon delivers 16,400 rounds/min and can engage up to 64 individual swarm targets in a single burst. Mountable on heavy tactical trucks or naval vessels, the HYDRA integrates a stabilised turret with built‑in AESA radar and electro‑optical sensors.

Unlike standard Gatling designs that rely solely on cams, the M64 HYDRA employs a hybrid cam‑and‑gear system with a dedicated rack‑and‑pinion rammer. This ensures each 32×173mm round is positively pushed into the chamber, even at maximum cyclic rate of 16,400 rounds/min across 64 barrels.

▶ Main gear train driven by 22 kW brushless motor – 12:1 reduction – Nominal torque 280 Nm – 7 cam tracks for 7 rings.
AESA 3D radar + IR camera + laser designator. Detects Class 1 micro‑drones up to 5 km. Simultaneous tracking of 300+ tracks.
64 barrels provide controlled ballistic dispersion. 64‑round burst in 0.23 seconds. Each barrel fires once per burst, covering a 6° cone.
32mm programmable airburst projectile. Releases 200+ tungsten sub‑projectiles in front of target. Highly effective against dense swarms.
960‑round disintegrating belt. Full reload by two crew members in under 10 minutes. Compatible with automated below‑deck magazine.
Built‑in RF jammer (433 MHz, 915 MHz, 2.4 GHz, 5.8 GHz) to disrupt drone control links before kinetic impact if required.
Link‑16 / JREAP‑C protocol. Full integration into air defense networks. Operates autonomously or connected to theatre C2.
The M64 HYDRA is designed for rapid deployment on heavy tactical trucks (e.g., M‑ATV 8×8, HEMTT) or naval patrol boats. The turret base incorporates a standard NATO bolt pattern and shock‑absorbing cradle, allowing field installation in under 5 hours. For naval applications, the system is marinised with corrosion‑resistant coatings and can be integrated with combat management systems.
