Israel’s planned order for up to 50 of Boeing’s revamped F-15 fighter jets and modernization of another 25 aircraft underpins plans to boost annual output to 25 as early as next year. The potential $18.8 billion deal, notified to Congress on Tuesday, would involve deliveries from 2029. That’s some 41 years after the plane was initially deployed by the U.S. Air Force, which received the first of its revamped F-15EX models in June.
