OM Defence Systems SPECTR

2026 DRONE TECHNOLOGY ELECTRONIC WARFARE AIR DEFENSE AUTONOMOUS AIRCRAFT

History

The OM Defence Systems SPECTR is an unmanned decoy aircraft designed to create a deliberately enlarged radar return. Its principal payload is an adjustable microwave retroreflector that can make the small aircraft resemble a substantially larger aerial target on radar.

SPECTR is intended to distract and exhaust hostile air-defense systems by presenting a radar signature resembling a genuine incoming threat. The aircraft combines autonomous navigation, electric propulsion, catapult launch, and a lightweight airframe with a 1.2 kg radar-reflector assembly.

The system was publicly displayed at the Eurosatory defense exhibition in June 2026. Reporting from the exhibition described a completed aircraft with published dimensions and performance data, establishing 2026 as the earliest supported physical milestone for the SPECTR configuration.

Development and public presentation

SPECTR was developed by OM Defence Systems as a purpose-built radar decoy. Militarnyi reported that the system was presented at Eurosatory in June 2026 and described it as an automated press-and-fly aircraft intended to deceive, distract, and deplete enemy air-defense resources.

Sources differ in their characterization of the developer's national identity. Defence Blog described OM Defence Systems as UK-based, while Ukrainian publications described the company as Ukrainian. The available subject metadata identifies the United Kingdom as the development country.

By August 2026, reporting stated that SPECTR had reached Technology Readiness Level 6, indicating that a prototype had been demonstrated in a relevant environment. The aircraft was also reported to be undergoing field trials with the Ukrainian military. These reports describe evaluation activity rather than confirmed operational service.

Design

Airframe and propulsion

SPECTR uses a lightweight polyvinyl chloride airframe and has a maximum takeoff weight of 12 kg. The aircraft is electrically powered and uses a pusher-propeller arrangement. It is launched from a catapult, allowing operation without a runway.

The reported dimensions are 1,400 mm in length, 2,690 mm in span, and 400 mm in height. The design is intended for relatively simple deployment from dispersed positions.

Radar-signature system

The defining component is a 1.2 kg adjustable microwave corner reflector operating across the 3–20 GHz frequency range. The reflector receives incident radar energy and returns a stronger signal toward the radar source. This increases the apparent radar cross-section of the aircraft.

Specifications presented at Eurosatory indicated that operators can vary the apparent radar cross-section from about 1 m² to more than 10 m². This allows SPECTR to imitate different classes of aerial target across several radar frequency bands. Other reporting summarized the effect as making the aircraft's radar signature appear roughly twenty times larger than its unenhanced signature.

The purpose of the enlarged return is to make hostile air-defense sensors treat the decoy as a more significant target. A defending force may track the aircraft, activate radars, or expend interceptor missiles against it. Radar activation can also reveal the location of emitting air-defense systems.

Navigation and control

SPECTR is described as an automated or autonomous aircraft. Navigation can use automatic, inertial, and GPS-based modes. Sources also describe the aircraft as resistant to electronic-warfare interference, although detailed resistance methods and performance figures have not been published in the available material.

Program status

By August 2026, SPECTR had reportedly reached Technology Readiness Level 6 and was undergoing field trials with the Ukrainian military. No source in the available material confirms series production, formal service entry, procurement quantities, or operational combat deployment.

OM Defence Systems has also presented SPECTR as a complementary system to its Kestrel hard-kill drone interceptor. In that concept, SPECTR performs the deception role while Kestrel provides a separate interception capability. The two aircraft remain distinct systems.
