Toward a national anti-drone capability
The ARKA Integrated Anti-Drone System (SHIELD SIA) represents an emerging operational capability, feasible with existing industrial resources in Romania.
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.
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.
Detection & Local C2
Fire Execution — FCS
Two overlapping networks
Every node joins a detection network and a fire network, coordinated by the central C2 — "The Eye".
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 angles — superior precision
- Zero blind zones — 360° coverage guaranteed
- Electronic-jamming resilience — neighbouring nodes compensate
- False-positive reduction — through multi-node confirmation
- Early warning 15–20 km — via C2 radar
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 allocation — the node with the most favourable angle has priority
- Sequential engagement — 2–3 nodes along the trajectory
- Anti-saturation — N nodes = N simultaneous targets
- Cumulative kill probability >99% — per trajectory
- Automatic deconfliction — zero friendly fire
An operational edge.

A product by itself has very limited intrinsic value — its value is directly proportional to how well it solves a client's problems. That's why ARKA offers multiple communication channels.
