Challenges to national defence in contemporary geopolitical situation

The growing presence of asymmetric threats require effective C-UAS systems. This study addresses the challenge of integrating sensors (RF and EO/IR) onto multirotor platforms while maintaining flight endurance. Of the four scenarios developed, it analyzes Use-case B in detail, mathematically comparing six variants of hardware modifications to a heavy drone during reconnaissance of a 300×300 m area against both active and radio-silent targets. The results reveal the paradox of SWaP limits: fully equipped "All-in-One" platforms excel against active targets thanks to rapid guidance but face critical battery depletion during area-wide reconnaissance of autonomous threats. For future research, therefore, cooperation among multiple platforms, reduced energy consumption, and the integration of effectors are proposed.
