RAVEN SHIELD — protective structural system

Suspended UAV protection structure. Two configurations, one dual barrier.

Complete overhead and lateral protection — a steel frame carrying a dual barrier of cable and gabion mesh over the protected asset.

The scale of the fixed-wing UAV threat

What a sustained one-way UAV campaign costs an industrial economy.

40–50K Large fixed-wing UAVs intercepted over one territory, 2022–2026

100s Infrastructure facilities damaged — plants, refineries, substations, fuel depots

$90–100B Minimum estimated direct damage, excluding lost revenue, repairs, logistics and payroll

Direct losses only. Indirect cost — interrupted production, emergency repair, re-routed logistics and idle payroll — is carried on top. Every one of those facilities is a fixed, mapped, immovable target.

Existing market solutions for counter-UAV protection

Most offerings stop at the net. RAVEN SHIELD covers the full class.

Threat class	Other companies	RAVEN SHIELD
Small UAV — up to 30 kg, 60 km/h	Covered	✓
Light UAV — up to 100 kg, 120 km/h	Partial	✓
Medium UAV — up to 200 kg, 200 km/h	Not covered	✓
Complete overhead and lateral protection	Rare	✓

Light net and cable systems are built for small rotary UAVs. RAVEN SHIELD is engineered for the medium class — 200 kg arriving at 200 km/h.

Proven operational experience under real threat conditions

SHIELD-SH lattice over a 50,000 cubic-metre storage tank — Protection of a 50,000 m³ storage tank — SHIELD-SH

Three UAVs impacted one structure. The tank kept operating.

The structures have demonstrated positive real-world performance, including confirmed fixed-wing UAV attacks at two facilities. These incidents validated the system's effectiveness in minimising damage risk and ensuring continuity of technological operations.

Three UAVs impacted a SHIELD-SH structure, where a significant number of structural elements were cut or removed.

A substantial structural safety margin and load-bearing redundancy.

Engineering

Cable and gabion mesh being installed on a lattice structure

SHIELD-SH · spatial lattice structure

Hyperboloid geometry.Maximum rigidity, minimum steel.

Single-sheet hyperboloid geometry — a lightweight yet rigid lattice that minimises steel consumption
High-strength galvanised steel — structural elements
Dual protective barrier — cable and gabion mesh, overhead and lateral
Sacrificial protection concept — frame and barrier absorb the UAV impact, preserving the integrity of the tank and equipment without progressive structural failure

SHIELD-P · portal frame structure

Non-permanent.No guy wires required.

Vertical columns and horizontal beams — interconnected with cable bracing and trusses
Protection system — cable and gabion mesh with integrated steel cables on the sides and overhead
Provision for vehicle access openings — the facility keeps operating
Full release of the entire side mesh — quick-release ensures rapid access for firefighting in emergencies

Area of application: 110–500 kV substations · oil & gas facilities and equipment · critical infrastructure assets

Dynamic and static testing

Qualified at a certified test site.

The structures have successfully undergone dynamic and static testing at a certified test site.

The mesh system successfully passed dynamic testing at a national rescue-service test centre, in accordance with the testing programme and methodology developed by the responsible state technical institute.
