Five US Air Force refueling planes have reportedly been hit and damaged in Iranian strikes on Prince Sultan Air Base in Saudi Arabia.
The planes were hit on the ground and are being repaired as they suffered partial damage, the Wall Street Journal reported.
No casualties have been reported in the incident.
This comes a day after a KC-135 refueling aircraft crashed while supporting operations in western Iraq on Thursday, resulting in the deaths of all six crew members.
Refueling planes are used for midair refueling of fighter jets, providing an aerial lifeline for aircraft striking targets deep inside Iran.
The US operates roughly 75% of the world's tanker aircraft, with the KC-135 Stratotanker being one of the most technically demanding manoeuvres in military aviation.
