(CNN) -- The U.S. Air Force is breaking out some of its heaviest hardware to send a message to North Korea.
A Pentagon spokesman said Monday that B-52 bombers are making flights over South Korea as part of military exercises this month.
"Despite challenges with fiscal constraints, training opportunities remain important to ensure U.S. and ROK (Republic of Korea) forces are battle-ready and trained to employ air power to deter aggression, defend the Republic of Korea, and defeat any attack against the alliance," Pentagon spokesman George Little said Monday in a meeting with reporters at the Pentagon.
Little said the eight-engine bombers first flew as part of the annual Foal Eagle training exercises on March 8 and were to fly again over South Korea on Tuesday.
