Federal agents have begun questioning U.S. technology companies on how their computer chips ended up in Russian military equipment recovered in Ukraine.
But investigators from a variety of countries have identified Western electronics in Russian weaponry found in Ukraine.
The federal probes come as researchers and security services from Ukraine, Britain and elsewhere report finding a host of Western electronics in Russian military gear damaged or abandoned in Ukraine.
None of the Western chips was specifically designed for use in military equipment, according to two electrical engineers who reviewed the component list.
Onsemi, a chip company based in Phoenix, said it stopped producing one of the chips found in the Russian equipment in 2008.
Analog Devices, the company behind more than a dozen of the components found in the Russian equipment, didn’t respond to requests for comment.
The RUSI researchers also reported inspecting a U.S.-manufactured component that the Ukrainian military found inside a Russian 9M949 guided rocket. »
