The Sentinel platform pairs an ultra-high thrust-to-weight airframe with hardened autonomy, giving small teams persistent eyes where conventional aircraft simply cannot fly.
An extreme thrust-to-weight ratio lets the Sentinel operate in rarefied air down to 20 kPa. With advanced avionics and constant IMU temperature control, it is rated for launch at 29,400 ft AMSL and a service ceiling of 36,000 ft — while remaining virtually undetectable with a near-zero radar signature and best-in-class ultra-low noise.
A best-in-class active ECM suite defends against GPS and radio jamming, working in tandem with a frequency-hopping command & control link. When the spectrum gets hostile, the Sentinel keeps flying, keeps transmitting, and keeps its operator in command.
Uncompromised operations in difficult terrain while prioritizing troop safety. Cold-soak launch at −25°C from 29,400 ft, all-weather IP67 weatherproofing and rain-capable systems give commanders genuine flexibility across seasons and theatres.
Fully programmable waypoint navigation on pre-downloaded maps, auto-functions for payload, and custom hover-time per waypoint. Flight plans can be altered mid-flight — add waypoints, change altitude, or drop to manual for semi-autonomous or ECM flight modes — with self-arming, auto take-off and auto-landing throughout.
Most tactical quadcopters give up around 15,000 ft. The Sentinel launches from nearly twice that altitude — and still climbs another 6,600 ft.
One gyro-stabilised turret, two sights, zero blind hours. Simultaneous stitched view of day and thermal channels — switchable across up to 9 colour palettes — enables faster, more accurate interpretation of the ground picture.

Both gimbals see the same battlespace at wide angle. Drive the master zoom to full telephoto and the T-90’s 160× reach isolates the target where the T-60’s 30× tops out.
At 0% both feeds are identical — same scene, same framing. At 100% the T-60 holds at 30× while the T-90 continues to 160×, a 5.3× tighter crop on the same target.
Zero ambient light, same target. Both cores share the identical 640×512 sensor at a 30 Hz refresh — the difference is reach. The T-60’s thermal sight is fixed at native field of view; the T-90 drives up to 8× digital zoom with AI super-resolution.
At 0% both cores frame the same 640×512 white-hot picture. At 100% the T-60 holds at native field of view while the T-90 closes to 8× — the same heat signature, eight times larger, with AI super-resolution preserving the read.
Both Sentinels share the same FHSS datalink architecture, combination sight and KAT-series smart control software — the T-60 pairs with the 7″ KAT 9 Pro, the T-90 with the 10.1″ KAT 11 Pro — so training, spares and mission planning carry across the fleet.
The man-portable pathfinder. Optimised for fast deployment by a one-man team: unpack, self-arm and airborne in under three minutes.
The long-stare variant. A high-density power module and extended-efficiency rotors buy up to 90 minutes on station and a 45 km reach — a full patrol cycle of unbroken coverage.

Specifications are subject to change without prior notice.
Every mission runs over a fully encrypted, secure digital link between aircraft and ground station — FHSS frequency-hopping with AES-grade channel encryption, so the mission map, live feed and telemetry you see below can never be intercepted or spoofed mid-flight.
Raw airframe recording, cloud-deck transit — the Sentinel holds a stable platform through reduced visibility with no gimbal drift and no loss of link.
Flight-test footage, unedited. Coordinates and battery telemetry redacted for operational security; airspeed, altitude and flight-time readouts left intact.
