WASHINGTON (Reuters) - The U.S. government is expected to announce on Thursday a $29.4 billion sale of new F-15 fighter jets and related equipment to Saudi Arabia, according to an industry participant familiar with the matter.

The deal covers 84 new Boeing fighter jets and upgrades for 70 more, the industry participant said.

The Obama administration cleared with Congress more than a year ago the potential sale of more than $60 billion of military hardware to Saudi Arabia over 10 to 15 years, including the F-15 sale to be announced by the White House on Thursday.
