St. Petersburg, — Russian technology company DOFA-Tek has unveiled the DF-1 Roscherk, a disposable, jet-powered interceptor drone designed to destroy other unmanned aerial vehicles (UAVs). The system was presented at the All-Russian Drone Congress 2026, held in St. Petersburg from October 7 to 9.
According to company specifications, the DF-1 has a takeoff weight of 15 kg, including a 1.5 kg warhead. It can reach a maximum speed of 500 km/h, has a stated range of up to 250 km and can remain airborne for up to 50 minutes. Its exact dimensions have not been disclosed.
DOFA-Tek General Director Marat Drofa said the interceptor can destroy targets through direct impact or by detonating its onboard warhead. It is launched from a rail using a solid-fuel booster. Technical Director Vitaly Dobrovolsky said the system can be deployed from the ground or rooftops. The drone has an all-metal structure, which the company says will simplify manufacturing and support large-scale production.
The company lists a cruising speed of approximately 400 km/h and an economical speed of around 200 km/h, with a range of up to 240 km in economical mode.
Testing and Production Plans
Drofa said the DF-1 has successfully completed its first two factory-testing stages. Final flight testing is scheduled to conclude in November 2026, after which DOFA-Tek plans to begin serial production. The company says agreements are already in place with several customers, but their details have not been disclosed.
DF-3 Gadyuka and DF-5 Iskra
DOFA-Tek also outlined two additional unmanned aircraft, both at the technical proposal stage.
The DF-3 Gadyuka (Viper) is a larger interceptor with a stated takeoff weight of approximately 240 kg, a maximum speed of 850 km/h, a cruising speed of 650 km/h and a range of up to 800 km. Its reported aerodynamic profile has been compared with that of the Italian Aeritalia G.91 light fighter-bomber. Its projected performance could support interception of certain cruise missiles, although this capability has not been independently demonstrated.
The DF-5 Iskra (Spark) is designed for strike missions. It has a proposed takeoff weight of 120 kg, a warhead capacity of up to 20 kg, a maximum speed of 850 km/h and a range of up to 1,200 km.
While the DF-1 is approaching the end of its factory-testing programme, the DF-3 and DF-5 remain at an early development stage. Independent verification of their performance and production readiness has not been established.
