Executive Summary

Drone threats across air, land, and sea—especially Group 1–3 multirotors, FPV kamikaze drones, and loitering munitions—demand layered counter-UAS defense. Gun-based airburst systems like Rheinmetall AHEAD and RapidFire offer low-cost, scalable protection. Ukraine’s battlefield accelerates C-UAS innovation now shaping NATO doctrine.

Drone threats span Group 1–5 systems and multiple domains (air/sea/land); the most acute near-term risks to maneuver forces and civilians are Group 1–3 multirotors, FPV kamikaze drones (including fiber-optic variants), small fixed-wing ISR, and loitering munitions.

Effective defense requires a layered C-UAS approach combining sensing (radar/RF/EO-IR) and multiple effectors (EW, airburst guns, interceptors, missiles, HPM/HEL). The U.S. Army’s ATP 3-01.81 doctrine and CRS outline this layered paradigm.
Gun-based C-UAS with programmable airburst (30–35 mm) delivers favorable cost-per-shot and deep magazines against swarming sUAS; Rheinmetall’s AHEAD and Thales/KND S RapidFire exemplify the state of the art.
Ukraine is the global crucible for rapid iteration in drones and counter-drone tech (FPV, fiber-optic FPV, EW, mobile C-UAS), with lessons diffusing to NATO programs.

Threat Landscape (What a gun system must stop)

Group 1–2 commercial multirotors (Mavic/EVO class): ISR, precision drops (0.3–2 kg); low/RCS, terrain masking, night operations. Ubiquitous on the battlefield.

FPV kamikaze drones: High-speed, all-angles-of-attack on vehicles/dismounts; extremely low cost; analog/digital C2; accelerating innovation in Ukraine.

Fiber-optic (FO) FPV: Tethered control over fiber resists EW/jamming; used for precise strikes in heavily contested EW.

Fixed-wing rucksack ISR (Group 2): 2–4 h endurance for artillery correction/comms relay. Examples include Quantum-Systems Vector, AV Puma.

Loitering munitions (Group 2–3): Precision anti-armor/anti-artillery systems (AeroVironment Switchblade family; Russian ZALA Lancet). Terminal high-angle dive profiles are challenging for point defense. Existing turret systems (like Sentradel) lack elevation above ~80 degrees.

One-way attack (OWA-UAV): Long-range prop-driven systems (Shahed-131/136/Geran-2) used for deep strike, often in mass raids that saturate air defenses and threaten civilian infrastructure. Jet powered drones like Geran 3 - 600 km/h and cruising altitude >9000 m = unreachable for anti-aircraft guns.

Attritable tactical VTOL fixed-wing: Longer-range ISR/strike (e.g., Shield AI V-BAT; Edge Autonomy Penguin).

Cross-domain drones: USVs (e.g., Magura class) for maritime strikes; UGVs as IED carriers—less relevant to gun C-UAS but part of layered defense planning.

Implication for gun C-UAS: Highest payoff is defeat of Group 1/2 FPV/multirotors and terminal windows of Group 2 loitering munitions within 300–3,000 m—where programmable airburst and precise cueing matter most.

How drones penetrate to attack convoys, soldiers, civilians

Low, slow, small (LSS) signature evades conventional air surveillance; clutter and terrain masking complicate detection.

Top-attack FPV dives at 100+ km/h exploit short reaction times and weak roof armor.
Massed OWA-UAV raids generate saturation, forcing high-end SAMs to expend costly interceptors; affordable guns at defended sites improve economics.
EW adaptation (FO-FPV; pre-programmed routes; inertial dead-reckoning) reduces jamming effectiveness; kinetic fallback (airburst) is essential.

Gun-Based C-UAS: Technology Benchmarks and Fit

Programmable airburst (30–35 mm): AHEAD (35 mm) projects a tungsten sub-projectile cloud programmed to burst in front of the target; optimized for small, fast aerial threats. Thales/KND S RapidFire (40 mm cased-telescoped) provides VSHORAD close-in defense for air/surface targets.

Representative systems:
- Rheinmetall Skyranger 30/35 & Skynex: Integrated sensors, 30×173 mm or 35 mm revolver guns, AHEAD ammunition; multiple European orders (incl. Denmark).
- Thales RapidFire (Land/Naval): 40 mm CT cannon; qualified 2025; designed for small UAS/USV defense.
Programmatic context: U.S. ATP 3-01.81 (Aug 2023) and CRS (Mar 2025) emphasize layered C-UAS with kinetic guns as a cost-effective inner layer alongside EW and interceptors.

Ukraine: Global Center of Gravity for Drone/C-UAS Innovation

FPV & LOE: Ukraine’s front lines iterate FPV tactics (including FO-FPV) and counter-FPV measures at unprecedented speed; this informs NATO CONOPS and procurement.

Systems in combat rotation: AV Switchblade, Quantum-Systems Vector, Edge Autonomy Penguin, Teledyne FLIR R70; extensive EW/counter-drone deployments (e.g., Kvertus).
Ecosystem: BRAVE1/“Test in Ukraine” initiatives accelerate fielding and partner trials for international companies.
