U.K. aerospace and defense company BAE Systems has agreed a 2.5 billion pound ($4.1 billion) deal with Oman for 20 aircraft.

BAE says Oman has signed the contract for 12 Typhoon fighter jets and eight Hawk aircraft, with deliveries expected to start in 2017.

The contracts cover the supply of the aircraft and in-service support, BAE added.

The deal is the latest in a series of contracts supply Oman: the country currently operates Jaguar fighter aircraft and trains pilots on an earlier variant of the BAE Systems Hawk, the defense giant said.

The deal will make the Gulf nation the seventh country to use the Eurofighter Typhoon jet, which is built by a consortium of European aerospace companies.
