Russia has stopped producing the Geran-3 jet-powered kamikaze drone and shifted its focus to the newer Geran-4 model, Ukrainian media report, citing data from the Main Intelligence Directorate of Ukraine’s Defense Ministry.

Russian forces are still using Geran-3 drones, which can reportedly reach speeds of up to 370 km/h and cover distances of up to 1,000 kilometers. According to Ukrainian intelligence, however, these aircraft come from previously accumulated stocks rather than current production.

The GUR described the Geran-3 as an intermediate step between the piston-powered Geran-2 and the newer jet-powered Geran-4. Its design largely retained the airframe and components of the Geran-2, while the main change was the replacement of the piston engine with a jet engine. The airframe itself underwent only minor modifications.

Russian specialists used the Geran-3 to test a number of technical solutions and gain operational experience with jet-powered unmanned aircraft, according to the Ukrainian intelligence assessment. Those developments were later incorporated into the Geran-4.

The newer version received a reinforced airframe designed from the outset for a jet propulsion system. Ukrainian sources say the design allows the drone to fly faster and perform maneuvers that earlier Geran variants could not execute.

The Geran-4 also has greater speed and flight range. Ukrainian sources claim these characteristics prevent Ukrainian kamikaze drones from intercepting the new model effectively.

GUR intelligence also reported finding 45 foreign-made components in the Geran-3, including parts originating from the United States, China, Switzerland, Germany and the United Kingdom.
