The Portfolio

Choose your platform.

Four fielded airframes — every one running the same KlmFly ground control app, the same encrypted datalink architecture, the same hardened build standard.

Vantrel series UAV Compact · One-Man Deployable
VANTREL

The stand-off specialist and the day/thermal generalist, in one 231×231×57mm airframe. Field-strip to a hard case, swap the battery in under 15 seconds, and fly again.

Why KLM Defense

One ecosystem. Every mission.

Different airframes for different mission profiles, but a single hardened foundation underneath all three — so switching platforms never means retraining crews or rebuilding infrastructure.

01
One app, every airframe.
KlmFly plans the mission, launches the aircraft and reads the sensor feed — identical across Vantrel, XROSSBAT and Sentinel.
02
Encrypted by default.
FHSS frequency-hopping with AES channel encryption protects the command and video link on every platform, end-to-end.
03
Built to MIL-STD-810G.
Operational from −55°C to +65°C depending on airframe, IP55–IP67 weatherproofing, auto-home on link loss or low battery.
04
Modular by design.
Swappable payloads and a common gimbal interface on XROSSBAT; quick-swap batteries across the line — mission-ready in minutes, not hours.
05
Precision at range.
Laser range finders on the upper-tier payloads — up to 1200 m on Vigilon 100, 1000 m on UC65 Pro — give true oblique distance to target, not a visual estimate.
06
Any light, every palette.
Dual stitched day + thermal feeds with up to 9 selectable thermal colour palettes on the flagship payloads, for faster target interpretation whatever the ambient light.
07
Navigates and fights through jamming.
GPS, GLONASS, Galileo, QZSS and NavIC-ready reception on every platform keep navigation holding up even if one constellation is degraded, spoofed or unavailable — paired with an active ECM suite across all platforms to enable operations in hostile, jamming-contested environments.
08
Everest-capable altitude.
Sentinel launches from 29,400 ft AMSL — higher than Mount Everest — and climbs to a 36,000 ft service ceiling, on the same autonomy stack that flies Vantrel and XROSSBAT at sea level.
09
AI compute onboard.
Vigilon 100 runs 4 TOPS of AI compute directly on the gimbal, not the ground link — identifying subject type, measuring range and closing speed, and holding a track through occlusion or hand-off. Argus 1200 pushes this further still, with 11 TOPS of onboard compute for even faster, more capable inference.
10
Ready in under 15 seconds.
Vantrel's quick-swap battery lets a single operator unpack, power up and launch from one case, no tools and no ground crew — under 15 seconds from spent battery to airborne again.
11
Built for high-wind ops.
Wind resilience up to 72 km/h on Sentinel T-90 and 60 km/h on XROSSBAT — real operational margin, not just calm-day flying.
12
Autonomous from launch to land.
Self-arming, auto take-off and auto-landing on Sentinel, with one-touch autonomous mission control from KlmFly — the operator stays on the sensor feed while the aircraft handles the flying.
