A drone factory in Kyiv destroyed by a Russian ballistic missile on Friday was owned by a US corporation registered in Delaware, in what appears to be the first time Moscow has targeted a US defence company in the conflict. Terminal Autonomy makes precision "deep-strike" drones with guidance systems that are resistant to Russian jamming signals, according to a person familiar with the company. The Russian state news agency Tass first reported on the attack on Sunday, citing the Russian defence ministry as its source. The report did not disclose that an American company owned the factory but mentioned that "specialists from a Ukrainian-American company" had worked there. An earlier version said that it appeared to be the first time Moscow has targeted a US company; that should have said US defence company.
