The U.S. military has introduced Ukrainian counter-drone technology in recent weeks at a key U.S. air base in Saudi Arabia, according to five people with knowledge of the matter, as it seeks to stem attacks that have destroyed aircraft and buildings, and killed at least one service member, Reuters reported. 

The deployment of a Ukrainian command-and-control platform called Sky Map at Prince Sultan Air Base, which has not previously been reported, is a sign of how Ukraine’s military has surged ahead in drone and counter-drone technologies that have been ​battle-hardened in its four-year war with Russia.

Ukrainian military officials arrived at the base in recent weeks to train U.S. warfighters with Sky Map, which is used widely by ‌the Ukrainian ‌military to detect incoming drone threats — including Iranian-developed Shahed drones — and launch counterattacks with interceptor drones.
