Boeing has won a contract to develop the F-47 next-generation combat aircraft for the U.S. Air Force that will spearhead future air wars and throw a lifeline to the company’s struggling military aviation business.

Russia on Friday accused Ukraine of blowing up a major Russian gas pumping and measuring station in the Kursk region near the Ukrainian border in what it called "an act of terrorism."

For Boeing, the win marks a reversal of fortune for a company that has struggled on both the commercial and defense sides of its business. It is a major boost for its St. Louis, Missouri, fighter jet production business.
