Last week, four Air Force B-1s flew directly to that base for a short-term deployment. USAF F-22s and Navy E/A-18G Growlers recently arrived there as well.
The US has lately grown its presence at Prince Sultan, a relatively bare base where USAF personnel have built up resources to support large-scale flight operations. Additionally, the US is in the process of bringing Patriot missile defense batteries, additional fighter squadrons, a Terminal High Altitude Area Defense System, and an air expeditionary wing to Saudi Arabia.
The Barksdale B-52s deployed to Europe in early October, and have extensively trained across the continent. That included receiving fuel and flying alongside French aircraft, and training along with B-2s from Whiteman AFB, Mo., in a large-scale exercise.
