Large Loitering Munition
Long-range, large-warhead loitering munition designed for strategic strike. Navigates by GPS/INS to pre-programmed targets over hundreds or thousands of kilometres; 2026 variants add onboard electro-optical seekers with machine-vision AI for terminal target acquisition, defeating GPS spoofing and enabling strikes on moving or relocated targets. Designed for saturation attacks that overwhelm air defences — a low-cost cruise-missile substitute produced in the thousands per month. Tactical employment is doctrinal and mass-driven: launches are batched in waves of dozens to over a hundred airframes routed along multiple axes, mixing decoys and real warheads to force the defender to expend high-cost interceptors on low-cost targets. Terminal approach is low-altitude to defeat medium-range radars, with cruise legs above the small-arms envelope but well below fighter and long-range SAM sweet spots — the geometry is deliberately inconvenient for every existing defence. Machine-vision seeker variants close the last kill loop autonomously: once the aircraft is within visual range of the target class it was trained on, GPS spoofing and INS drift stop mattering. The defensive problem is arithmetic. Medium-range SAMs and fighter cannon kill this platform reliably per engagement, but at a per-round cost that inverts the exchange ratio; interceptor drones and gun-based C-UAS shift the ratio back toward the defender but require dense coverage of every likely ingress corridor. High-power microwave and laser systems close the cost gap once fielded at scale, but 2025–2026 fielding remains partial. Recent combat observations: sustained saturation campaigns against Ukrainian energy and port infrastructure with launches reaching 5,000+ per month by late 2025 (ISIS analytical review), jet-powered variants entering serial production from early 2025 with speeds near 600 km/h (UAS Vision), a 2026 seeker variant flown into a Ukrainian grain ship in the Danube delta with jamming ineffective against its onboard machine-vision guidance (Euromaidan Press Jul 2026), and the 170-airframe Iranian direct strike on Israel in April 2024 as the canonical demonstration that even near-total interception by a layered defence is economically unsustainable at scale (CSIS Drone Saturation, RUSI Air War).
Technical Specifications
Tactical Roles
Advantages
- + Very long range for relatively low cost
- + Overwhelms air defenses through mass/saturation use
- + Autonomous terminal guidance (GPS/INS)
- + Low radar cross-section vs traditional cruise missiles
- + Cheap enough for mass production and attrition use
Disadvantages
- − Slow speed makes it interceptable by AA and fighters
- − Loud engine (detectable acoustically at distance)
- − Relies on GPS — vulnerable to area spoofing
- − Cannot engage moving targets
- − No abort or return capability
Real-World Usage
- ▸ Shahed-136 / Geran-2 — Iranian-designed, used in waves by Russia against Ukraine (5,000+ launched/month by late 2025 per ISIS analysis)
- ▸ Shahed-238 / Geran-3 — turbojet-powered variant in serial production from early 2025, ~600 km/h, 90 kg warhead
- ▸ Geran-4 / Geran-Siker — jet-powered 2026 variant with onboard EO seeker + machine-vision AI ('Siker' module) for terminal guidance; used against Ukrainian grain ships and moving targets, defeats GPS/INS spoofing
- ▸ Harop / Harpy — Israeli anti-radiation loitering munitions
- ▸ Phoenix Ghost — US-designed loitering munition for Ukraine
- ▸ April 2024: Iranian direct strike on Israel — 170+ Shaheds launched, near-total interception by layered defense

⚠ How This Drone Evades Defenses
Active adversary tactics — not passive limitations
- ▸ Mesh networking — losing individual nodes does not break the swarm
- ▸ Multi-axis simultaneous attack overwhelms tracking and engagement cycles
- ▸ Onboard autonomy reduces RF emissions exploitable by detection
