Integrated Anti-Drone System · SHIELD SIA

An operational capability, ready now

The ARKA Integrated Anti-Drone System (SHIELD SIA) represents an immediately necessary operational capability, achievable with existing industrial resources in Romania.

System concept · Distributed battery

A single distributed air-defence battery

Low-altitude attack drones are today's highest cost-effectiveness asymmetric threat. The answer is depth zone-defence — domestically produced and network-deployable at national scale.

The Integrated Anti-Drone System is a modular low-altitude air-defence solution — early detection, automatic identification and engagement at maximum effective range, with absolute inhibition of civilian and friendly aircraft. SIA is not a collection of individual systems; each node is a cell of one integrated organism.

Operational necessity

Why a networked battery — and why now.

$20–50k
Cost of a Shahed-type drone — versus hundreds of thousands of dollars for a single missile interceptor.
<250 m
Structural blind zone of conventional radar below this altitude — ground clutter + minimum antenna elevation.

CONTEXT

Conventional point-defence is costly, scarce and cannot cover the extended perimeter of an urban centre or strategic objective. The design philosophy eliminates single-supplier dependency through a national-integrator architecture: ARKA designs the system and manufactures the mechanical, electrical and software structures, while specialised electronic and fire components are procured from multiple interchangeable suppliers — without redesign.

Two modules per node

Each node is two physically separate modules — detection and fire — so recoil never disturbs the optics.

Two overlapping networks

Every node joins a detection network and a fire network, coordinated by the central C2 — "The Eye".

Network 01

Detection Network

All sensors from all nodes fuse data in real time at C2. Multi-node triangulation sharpens precision, erases individual blind zones and auto-compensates jamming of one node via its neighbours.

  • 3D position from multiple anglessuperior precision
  • Zero blind zones360° coverage guaranteed
  • Electronic-jamming resilienceneighbouring nodes compensate
  • False-positive reductionthrough multi-node confirmation
  • Early warning 15–20 kmvia C2 radar
Network 02

Fire Network

Firepower is coordinated centrally. The system allocates engagements automatically — the node with the optimal angle fires while the others are inhibited, eliminating ammunition waste and friendly fire.

  • Optimal allocationthe node with the most favourable angle has priority
  • Sequential engagement2–3 nodes along the trajectory
  • Anti-saturationN nodes = N simultaneous targets
  • Cumulative kill probability >99%per trajectory
  • Automatic deconflictionzero friendly fire
