Ukraine has found the US component in a Russian jet-powered drone targeting civilians, supermarkets, medical warehouses, and bridges. According to its Defense Intelligence, the new weapon contains a PNI5GA magneto-inductive sensor made by the US company PNI Sensor.

The US-made navigation component adds to evidence that Western technology continues to appear in Russia's strike drones. HUR had already identified US-made chips in the Geran-4 in May, but the newly reported PNI5GA is a navigation sensor in a modified version of the drone that Institute for the Study of War (ISW) says Russia may seek to field ahead of winter.

A Russian engine replaces the Chinese one

Russia has also replaced the drone's Chinese-made Telefly turbojet engine with a Russian-made equivalent produced in Alabuga. Russia is using the Alabuga zone to bring more of its drone production home rather than importing Iranian or Chinese parts, according to the ISW.

"The remaining electronic units and components are unchanged and identical to those used in previous Geran UAVs," HUR said.

What the warhead is built to cut

The modified drone also carries a specialized KRSN warhead designed to cut through bridge structures and power-line supports. Presidential adviser Serhii Beskrestnov described the warhead on 30 September, saying it consists of a 40-kilogram main charge and four strike modules. Its warhead is meant to destroy hardened targets made of steel and concrete and to damage cable-stayed bridges.

Russia has stepped up strikes on Kyiv's Northern and Southern bridges across the Dnipro in recent days with such drones.

However, Russia may try to field more resilient and more dangerous versions of its strike drones before Ukraine has effective countermeasures in place. Russia could use them to degrade Ukraine's energy infrastructure and logistics ahead of a winter strike campaign that it said will very likely be brutal.
