After the Houthi attack on Saudi oil infrastructure on 14 September 2019, Saudi Arabia tasked F-15 fighter jets armed with missiles to intercept low flying drones, difficult to intercept with ground based high altitude missile systems like the MIM-104 Patriot with several drones being downed since then. On 2 July 2020, a Saudi F-15 fighter jet shot down two Houthi Shahed 129 drones above Yemen. On 7 March 2021, during a Houthi attack at several Saudi oil installations, Saudi F-15s shot down several attacking drones shot down using heatseeking AIM-9 Sidewinder missiles, with video evidence showing at least two Samad-3 UAVs and one Qasef-2K downed.
