Troops are being sent to the remote desert base as it would be unlikely that Iranian missiles would be able to strike the area.
According to reports, soldiers could be deployed to Saudi Arabia as early as next week.
It is understood that Pentagon officials want more troops in the region as tensions continue to sour between the US and Iran.
Images taken in the region in late June and earlier this month show significant preparations being made in the region.
Jeffrey Lewis, director of the East Asia Nonproliferation Project, told CNN: “A small encampment appeared at the end of a Prince Sultan runway by June 27, suggesting that improvements are already underway.
“The encampment to the east of the runway is typical of Air Force engineering squadrons deployed overseas.”
The US accused the Islamic Republic of launching an attack on two oil tankers before shooting down one of its drones.
Royal Marines also seized an Iranian tanker near Gibraltar when it was suspected it was en route to trade oil with Syria, which has sanctions imposed on it.
But Iran has since fired back, with the country’s Supreme Leader Ali Khamenei saying: “Evil Britain commits piracy and steals our ship and gives it a legal appearance.”
