A U.S. Air Force unit headquartered in Ohio chalked up $19 billion in military sales to foreign countries in fiscal 2015, according to the Dayton Daily News.

The sales, handled by the Air Force Security Assistance and Cooperation Directorate at Wright-Patterson Air Force Base through the U.S. Foreign Military Sales program, included F-35 Lightning II aircraft to South Korea for $6.3 billion; F-35s to Israel for $2.8 billion and to Japan for $1 billion.

Also high in the directorates list of handled FMS deals was the billion-dollar upgrade to Singapore's F-16 fighters, the newspaper said.

"We are selling state-of-the-art technology around the world," Col. Bruce Monroe, senior materiel leader for the directorate's international division was quoted as saying. "The majority of our sales are complex systems that are in the United States Air Force today."

The Dayton Daily News , citing the U.S. Department of Defense figures, said U.S. Foreign Military Sales was almost $47.1 billion in fiscal 2015, compared to $27.8 billion in 2013 and $34.2 billion in 2014.
