WASHINGTON • Boeing Co. has been awarded a $6.2 billion contract for 36 F-15 aircraft for Qatar’s air force, the Pentagon said in a statement on Friday.

The aircraft, which will be manufactured by Boeing in north St. Louis County, are expected to be delivered to Qatar by the end of 2022.

“This contract provides for the foreign military sales requirement to procure 36 new F-15QA aircraft for the Qatar Emiri Air Force,” the Pentagon said in a statement.

The contract’s announcement is likely to be welcomed by the Qatari government and comes amid an ongoing diplomatic row between Qatar and a number of its Gulf neighbors, including Saudi Arabia, Bahrain and the United Arab Emirates.

A deal to sell the fighters was signed in June but had been several years in the making.

While the F-15, an aircraft originally developed by McDonnell Douglas, is assembled in St. Louis County by Boeing, a network of suppliers mean the job impact of a Qatar deal will be widespread.
