• Arcani's HARK detects, classifies, and localizes drone threats in real-time.
• HARK has been tested in NATO's Steadfast Dart 2026 and Project Vanaheim 2025.
• The system uses artificial intelligence and spatial acoustics to extract usable signals.
• HARK reduces cognitive load and improves time-to-decision for operators.

The development of HARK may indicate a shift towards using acoustic sensors for drone detection, which could provide a reliable and practical solution for modern battlefield environments. This technology suggests that sound can be a valuable layer of situational awareness, potentially changing the workflow for operators and enabling more efficient decision-making.
