DEFENCE giant BAE Systems has won a £2.5 billion deal to sell 20 aircraft to Oman, helping to sustain thousands of jobs in the UK.

The contract for 12 Typhoon and eight Hawk aircraft was welcomed by Prime Minister David Cameron, who paid a visit to the Middle Eastern state yesterday.

BAE said it was an important export contract that supports its strategy to grow international markets and export business.

The aircraft will be built in the UK and will help to sustain 6000 high-technology and engineering jobs across sites in Warton and Samlesbury, both in Lancashire; and Brough, East Yorkshire.

Aircraft manufacture will begin in 2014, with delivery expected in 2017.

The Omani ministry of defence becomes the seventh operator of Eurofighter Typhoon and the third export customer, after Saudi Arabia and Austria.

BAE said there was great interest in the Typhoon and Hawk aircraft.

Guy Griffiths, group managing director for BAE Systems' International business, said: "Receiving this contract is an honour and is excellent news for both BAE Systems and the Eurofighter Typhoon consortium.

"BAE Systems has a long history of working in Oman and we are delighted this contract will enable us to continue to work together."

Before his arrival in Muscat, the Prime Minister dismissed concerns about Britain selling arms in the region.

He said: "Every country in the world has a right to self-defence and I'm determined to put Britain's first-class defence industry at the forefront of this market, supporting 300,000 jobs across the country."
