Ukrainian developers have presented two independent systems that reflect different directions in modern unmanned warfare: the autonomous SYCH-AIR electronic countermeasure system and the reusable Backfire fixed-wing strike UAV. They are not described as one integrated complex, but together illustrate how Ukraine is developing both protection from FPV attacks and aircraft for missions at considerable depth.
SYCH-AIR detects, analyzes and suppresses
SYCH-AIR is designed to counter FPV drones using analog video transmission. It continuously scans the radio spectrum, searches for stable video signals and activates coordinated interference on the confirmed channel without requiring an operator to search manually through every frequency.
The workflow has three stages: spectrum reception, signal analysis and suppression. A multiband receiver scans the airwaves, algorithms check signal stability against RSSI thresholds, and a VTX module generates interference on the detected channel. The presented materials indicate about two seconds for scanning and roughly five seconds for suppression activation.
Frequency coverage and modular architecture
The displayed configuration covers the principal FPV areas from about 1 to 8 GHz. Modules are available for 1.2 GHz, 3.3 GHz and 5.8 GHz, while a replaceable module extends coverage around 7.2 GHz. Single-band, dual-band and triple-band versions allow operators to select the architecture for the local radio environment.
Modularity matters because FPV teams regularly migrate to less congested frequencies. Instead of replacing the entire system, the operator can adapt receiver and transmitter modules. The architecture also permits integration on ground platforms or other carriers with suitable antennas, power and active cooling.
Field results and practical limits
A field test shown with the Volt unmanned ground carrier recorded loss of hostile video in 19 of 20 approaches. The stated reaction distance was 80 to 150 meters, reaction time ranged from one to four seconds, and approximately 88 percent of signals within the monitored spectrum were detected.
These figures describe a specific test rather than a universal guarantee. Effective distance changes with transmitter power, antennas, terrain, line of sight, reflections and the electronic environment. Correct placement and cooling are also essential because high-power VTX modules generate significant heat.
Coexistence with friendly drones
SYCH-AIR detects an analog signal but does not determine whether it belongs to a friendly or hostile aircraft. Coordinated frequency planning is therefore necessary. A predefined safe window can remain open for friendly video links while interference covers the rest of the selected spectrum.
Backfire as a reusable aircraft
The second product is the Backfire reusable fixed-wing strike UAV. It uses electric propulsion, launches from a pneumatic catapult and can return by parachute or conventional aircraft-style landing. Recovering the airframe preserves its avionics, optics and communications equipment for subsequent missions.
The displayed version has a wingspan of 3.4 meters, a length of two meters and a takeoff weight of 42 kilograms. Its payload is stated at up to 14 kilograms, flight range at up to 180 kilometers, deployment time at about five minutes and strike accuracy at up to five meters.
Navigation, communications and payload
The aircraft combines a protected UNA satellite antenna, inertial navigation and a ballistic computer. Additional navigation can use Sine.Link beacons, while communications and telemetry are described through Sine.Link and Starlink with remote control capability. Daylight and thermal cameras support operation in different visibility conditions.
Backfire is designed for flexible payload selection rather than one fixed munition. The stated mission set includes bombing, remote mine laying and logistics. A complete system includes three aircraft, a catapult, ground control station, additional batteries and spare parts.
Why the two products matter
SYCH-AIR protects positions, vehicles and infrastructure from analog FPV attacks, while Backfire carries payloads over a much greater distance. Their common features are modularity, rapid deployment, reduced dependence on continuous manual control and adaptation to contested navigation and radio conditions.
For partners and investors, the products demonstrate a broader Ukrainian industrial base involving RF modules, navigation, telemetry, ground stations, software, robotic carriers and serial production. The next challenge is stable reproduction of the stated performance, manufacturing scale and a service system capable of supporting equipment throughout its operational life.
