Qatar is interested in buying an early warning radar system valued at more than $1bn from the United States.
The Defence Security Cooperation Agency said it has notified Congress of a possible foreign military sale to Qatar of a FPS-132 Block 5 Early Warning Radar (EWR) and associated equipment, parts, training and logistical support for an estimated cost of $1.1bn.
"This proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security of a friendly country that has been, and continues to be, an important force for political stability and economic progress in the Middle East," the Agency said.
It added that the acquisition of the air defence system would "provide a permanent defensive capability to the Qatar Peninsula as well as protection of the economic infrastructure and well-being of Qatar".
The Agency said the sale would also help strengthen Qatar’s capability to "counter current and future threats in the region and reduce dependence on US forces".
The principal contractor will be Raytheon Company in Massachusetts, the statement added.
"Implementation of this proposed sale will require the assignment of additional US Government or contractor representatives to Qatar," the statement said, adding that specific numbers will be the subject of future negotiations.
