KR-DH40 Portable Box-Catapult Fixed-Wing Patrol UAV

KR-DH40 is a portable box-catapult fixed-wing UAV built for fast patrol work and quick-area coverage. Box-catapult launch keeps deployment simple—no runway needed—and supports rapid turnarounds from constrained sites. It’s designed for routine waypoint flying, with easy-to-plan performance under load. KR-DH40 supports 3–5 kg equipment capacity, with speed in the 110–180 km/h range. Endurance scales with load: 50+ minutes at 3 kg, and 30+ minutes at 5 kg (depending on load and flight profile). For sustained coverage, a launcher vehicle can carry multiple airframes—up to 6 aircraft per vehicle—so teams can rotate flights and keep coverage continuous.
