Orbital ATK has secured an order to deliver non-US standard ammunition (NSA) to the US Department of Defense (DoD) in support of unidentified international allies.

The $50m order was awarded by the US Government under indefinite delivery / indefinite quantity (IDIQ) and basic ordering agreement (BOA) contracts.

Under the NSA programme, the US army and its allies have received small and medium-calibre ammunition, grenades, mortars, as well as munitions for tanks and aircraft.

Including the current order, Orbital ATK won orders worth more than $200m last year under the NSA programme.

"The US army and its allies have received small and medium-calibre ammunition, grenades, mortars, as well as munitions for tanks and aircraft."

Since the beginning of the NSA programme in 2008, the company has been a major supplier to the US Government.

Orbital ATK functions as the operator of the US Army’s Lake City Army Ammunition Plant located in Independence, Missouri, US.

It currently operates as the largest developer of small-calibre ammunition for the US DoD.

In September and October , the company received multiple delivery orders worth $126m from the US Government to provide NSA for the US DoD in support of international allies.
