The United States will deploy a Patriot battery, four Sentinel radars, and approximately 200 support personnel to Saudi Arabia, the US Department of Defense announced on 26 September.
"This deployment will augment the kingdom's air and missile defense of critical military and civilian infrastructure," it said. There was no indication of when or where the Patriot and Sentinels will be deployed.
The statement said additional forces that include two more Patriot batteries and a Terminal High Altitude Defense System (THAAD) had been ordered to maintain a heightened state of readiness to deploy to the kingdom if needed.
The US already has at least one Patriot deployed at Prince Sultan Air Base in Al-Kharj in central Saudi Arabia, which arrived in July as part of a wider US effort to deter Iranian attacks.
