ED-4 / Tactical UAS / Medium-range

Your sky.
Your platform.

A medium-range, trivially deployed, attritable VTOL system for operators who measure success in sorties, not airframes.
Designed and manufactured in COLOMBIA.

Built for the
missions you actually fly.

One airframe, four mission profiles. Reconfigure between sorties, not between programs.

ISR & Reconnaissance

Persistent overwatch with EO/IR fusion. Stand-off observation across 70 km of contested airspace, beyond visual line of sight, with full-motion imagery streamed back over an encrypted datalink.

[ 04 / Differentiation ]

No runway.
No crew.
No problem.

Three constraints we removed at the spec — so you don't have to design around them.

01

Attritable by design.

Operators won't fly a $400K asset where it could be lost.
Built at a price point that lets the mission, not the airframe, set the risk tolerance. We optimized cost-of-loss as a first-class spec — not as a press release after the fact.

02

BVLOS from minute one.

Range-of-sight ops cap utility at a few kilometers.
70 km operational radius with encrypted C2 and over-the-horizon relay, designed against the FAA Part 108 / NPRM-2024 envelope. Beyond-visual-line-of-sight isn't a future feature — it's the baseline.

Built for
real operating environments.

Engineered around the failure modes that ground other platforms — heat, dust, weak signal, no second chance.

EO + IR dual payload

Stabilized gimbal carries electro-optical and thermal imagers in a single sortie. Day, night, smoke, dust.

Field-swappable battery

Tool-less pack change in under two minutes. Sustained sortie generation without a depot or charging crew.

6S22 AhHot-swap
PROP-01

Hybrid VTOL propulsion

Quad-lift rotors for vertical phase; pusher propeller for cruise. Battery-isolated motor pods reduce single-point failure on lift transition.

AVN-02

Triplex-redundant autopilot

Three independent flight-control units, voting in software. Mission continues on single-controller failure; degraded recovery on dual.

DLINK-03

Encrypted command + control

AES-256 over a frequency-hopping mesh radio. LOS to 70 km, BLOS via SATCOM relay. Open architecture for customer-side encryption.

PAY-04

Modular payload bay

10 kg / 14 L bay with standardized power, ethernet, and CAN bus. Swap EO/IR, SAR, comms, or LIDAR without ground tooling.

PWR-05

Swappable energy module

Tool-less Li-ion pack change in under two minutes. Sortie-rate sustained without a depot or a charging crew on-site.

NAV-06

GPS-degraded navigation

Visual-inertial fallback with terrain-relative reference. Mission continues through jamming or canyon shadow without operator intervention.

Cover the ground a fixed-wing crew can't reach in a day.

From a single launch point, the ED-4 owns roughly 15,400 km² of air. That's a perimeter, a fire-line, and three pipelines — all from one crew, one case, one battery rotation.

The answers procurement
asks for first.

Lead times, compliance, integration. Send anything else through the form below.

We don't publish list pricing. The platform is engineered for an order-of-magnitude lower cost-of-loss than comparable Group 2 fixed-wing UAS. Contact us with mission profile and quantity for a configured quote.

Yes. The ED-4 is built on a Section 848-compliant supply chain. We can provide a per-component country-of-origin manifest under NDA for customers who require it.

Yes. The bay is open architecture: standardized power (28 V), ethernet, and CAN bus. We provide a payload SDK and integration support; first-flight integration timelines run two to six weeks depending on payload complexity.

Initial customer units are eight to twelve weeks from PO, depending on payload configuration. We don't quote lead times we can't hold.

Yes, subject to U.S. export control. The ED-4 is ITAR-classified at the system level; we work with allied government and infrastructure customers under appropriate license.

Mission planning, transition, route, and contingency are autonomous. An operator is always in the loop for take-off authorization, mission-state changes, and payload release where applicable. Hands-on-stick is optional, never required.
