A British aerospace and defense company has signed a multi-billion-dollar contract to supply 20 military aircraft to Oman.

BAE Systems said Friday the $4.1 billion contract will provide Oman with 12 Typhoon fighter jets and eight Hawk jet trainers. Delivery of the aircraft is slated to begin in 2017.

BAE said the contract covers the supply of the aircraft and in-service support.

The move will safeguard thousands of jobs in Britain.

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

Earlier this week, BAE said that it has not resolved issues with a $7 billion contract it signed with Saudi Arabia in 2007 to supply 72 aircraft. BAE warned its shares could take a hit if an agreement is not reached soon.
