Iran's Gulf neighbour, the United Arab Emirates, has signed a deal worth $3.3 billion to buy missiles from U.S. firm Raytheon, a newspaper reported on Saturday.

The U.S. Defense Department said in September it had proposed the sale of air defence systems and helicopters to the UAE with a total potential value of more than $9 billion.

The main item in the Pentagon-proposed package was Terminal High Altitude Area Defense, or THAAD, worth up to $7 billion. The system is built by Lockheed Martin Corp with a system radar from Raytheon Co.

The National, an Abu Dhabi based-newspaper, said the deal was to buy Patriot missiles.

The proposed package included up to $121 million for Patriot Advanced Capability-3 Missile Systems from Raytheon and Lockheed Martin.

"The agreement ... includes technology, training and supply of the medium-range missile system, which is part of a multi-tiered defensive shield the UAE Armed Forces is building to protect the nation from perceived threats in the region," it said.
