Non-U.S. standard ammunition has been ordered by the U.S. government from Orbital ATK for supply to undisclosed international allies.

The orders were issued in September and this month under an indefinite-delivery/indefinite-quantity contract and total about $126 million.

"Orbital ATK has long been a reliable source of affordable, high-quality ammunition to the U.S. Armed Forces and its allies across the globe," said Kent Holiday, vice president and general manager of Orbital ATK's Small Caliber Systems Division of the Defense Systems Group. "We are honored to support our Army customer in every facet of ammunition requirements they may have, and these significant orders continue Orbital ATK's legacy of commitment and performance to the U.S. Army NSA program."

Orbital ATK operates the U.S. Army's Lake City Army Ammunition Plant in Independence, Mo., and is the largest manufacturer of small-caliber ammunition for the U.S. Department of Defense.

Additional details of the orders were not disclosed.
