• Ukraine’s military has published new information about Russia’s jet-powered Geran-3 attack drone.
• It reports that the drones are full of foreign-made parts and appear to be immune to electronic warfare.
• The Geran-3, modeled after an Iranian drone, is faster than its predecessor.

Russia’s new jet-powered attack drones are full of foreign parts and built with jamming-resistant technology to shield them from electronic warfare, the Ukrainian military said Tuesday.

Ukraine’s military intelligence agency, known as the HUR, published new details about the Geran-3, a Russian drone modeled after the Iranian-made Shahed-238, including what’s inside the deadly weapon.

The Geran-3 first appeared in Ukraine earlier this year, and the drone has since become a common element of Russian attacks. It is a faster, more advanced iteration of the Geran-2, Russia’s domestically produced version of the Iranian Shahed-136.

Unlike the Geran-2, which is propeller-driven, the Geran-3 has a turbojet engine that allows the drone to move at speeds of up to 370 kilometers per hour (230 miles per hour) with a range of 1,000 kilometers (620 miles). The weapon is packed with explosives and detonates on impact after diving toward its target.

The Geran-3 usually reaches maximum speed in areas covered by Ukrainian air defenses and during the terminal phase of its flight, the HUR wrote in a statement shared to the Telegram messaging app.

The HUR said that the Geran-3’s internal layout and electronic units are similar to those of the Geran-2 variant, and available data suggests that this new jet-powered drone is equipped with the same camera and video transmission system as its predecessor.

However, the Geran-3 is notably outfitted with a satellite navigation system that appears resistant to the extensive electronic warfare tactics used to counter drones on both sides of the war.

Nearly 50 foreign components are inside the Geran-3, with origins in a handful of Western countries — including the US, UK, Switzerland, and Germany — and China, the HUR said. Beijing has long been accused of providing critical technology to Russia, a claim it has denied.
