(Adds comments from Saab and Boeing)
WASHINGTON, Sept 27 (Reuters) - Boeing Co was selected to build the U.S. Air Force's next training jet in a contract worth up to $9.2 billion over the life of the program, the Air Force said on Thursday.
Boeing teamed up with Sweden's Saab AB to develop a new plane for the competition, beating out Lockheed Martin Corp and Leonardo DRS.
The Air Force plans to purchase 351 of the jets. The service expects the program to reach full operation in 2034.
In its bid, Lockheed had offered a modified version of its T-50 training jet developed jointly with Korea Aerospace Industries Ltd while Italy's Leonardo DRS had offered the T-100, a modified version of the Italian aerospace company's M-346.
The Air Force wants to replace its aging fleet of T-38 planes, which are nearly 50 years old. Analysts have said it could eventually buy up to 600 planes.
Winning the contract is significant for Boeing, which reorganized its defense business more than a year ago in the hopes of a "franchise level" victory such as the trainer.
Landing big defense contracts had been difficult for Boeing, but Leanne Caret, chief executive of Boeing's Defense, Space & Security since February 2016, has helped the company win more contracts.
"Today's announcement is the culmination of years of unwavering focus by the Boeing and Saab team," Caret said in a statement. "We expect T-X to be a franchise program for much of this century."
The award from the Air Force comes after Boeing has had trouble delivering to the Air Force its new in-air refueling jet, the KC-46.
In a statement Saab said the award means Boeing can now begin placing orders with its suppliers, including Saab, but has not done so yet. Saab said that more than 90 percent of Boeings offering will be made in America, supporting more than 17,000 jobs in 34 states.
