The UAE-based company ADASI, a subdivision of EDGE, has designed and developed the QX-4, a new generation of UAV loitering munitions able to carry up to two precision-guided bombs. The drone was unveiled during IDEX 2021, International Land Defense Exhibition that was held in Abu Dhabi, February 2021.

The QX-4 is the largest variant of UAV (Unmanned Aerial Vehicle) loitering munitions designed by ADASI in the QX-family, but it is based on a different design consisting of a fuselage with fixed-wings and a twin-tail configuration with the control structures arranged in V-shape.

The QX-4 is electrically powered by four twin-blade propellers, with two mounted at the rear of the fuselage and one mounted on the lower part of each wing. It features vertical take-off and landing (VTOL) capabilities. The landing gear consists of 4 skid shoes without any wheel.

The QX-4 is equipped with an electro-optic gimbal fitted on the lower part of the drone's nose which is equipped with TV/Thermal tracker and seeker. The operator can control the QX-4 thanks to a ground control station with a communication link providing video and control data capabilities.

The QX-4 has a maximum takeoff weight of 20 kg. It can easily be transported on a light vehicle. It has an operational ceiling of 2,000 m and a cruising altitude of 1,000 m. The drone has a flight range of 40 km and a flight endurance of 90 min.

The QX-4 has a payload from 2.5 to 5 kg that can include up to two precision-guided bombs. The precision-guided systems use sophisticated Artificial Intelligence algorithms to target and strike, boasting an accuracy of 1 m CEP (circular error probable) – with an aim similar to laser-guided munitions.
