Russian experts found batteries from NASA's Mars mission in the APU UAV. One of the first enemy FPV drones that was provided to us had the same battery as those used by the Americans in NASA’s Mars mission.

These batteries were installed with the expectation that FPV drone would be used in winter at sub-zero temperatures. Earlier, Kuzyakin said that Russia had created the Joker-10FPV drone, which explodes when it hits an enemy. He suggested that the first such drones were assembled by Ukrainian troops with the help of American specialists.
