According to a Reuters story, the US has started using Ukrainian technology at Prince Sultan Air Base in Saudi Arabia to combat Iranian drones, a decision that reflects weaknesses in its air defence capabilities.
According to sources, the Ukrainian command-and-control software "SkyMap," which has been utilised in Ukraine's conflict with Russia, was installed by US forces. It is specifically used to detect and intercept Iranian Shahed drones.
According to the article, Ukrainian military specialists have come to the site to instruct US staff on how to use the system.
The decision is in contrast to earlier statements made by Donald Trump, who on March 6th said, "We don't need their help defending against drones," in response to Ukrainian President Volodymyr Zelensky's offer of assistance.

However, a change in strategy has been brought about by events at Prince Sultan Air Base, which recently experienced intense attacks that damaged fuel tankers and destroyed an E-3 Sentry radar aircraft.
Despite substantial spending, military analysts told Reuters that the action reveals "longstanding gaps" in US air defence coverage, pointing out that the facility now uses a combination of Ukrainian and US weapons, including Coyote.
According to sources, early testing of some systems encountered difficulties, such as an event where a Merops interceptor lost control and crashed inside the facility, underscoring the technical difficulties in addressing the growing threat posed by drones.
