General Dynamics Land Systems (GDLS) has secured a $1.22bn contract to deliver Interim Maneuver Short-Range Air Defense (IM-SHORAD) systems to the US Army.

Under the contract, the US Army also placed an initial order of $230m for 28 Stryker IM-SHORAD vehicles.

As agreed, GDLS will be responsible for manufacturing, testing and delivering the IM-SHORAD systems.

“This dedicated SHORAD capability adds a new operational dimension to the Stryker fleet in all of the army’s manoeuvre formations.”

The company will determine work locations and funding following the placement of every order.

GDLS has production sites across the US in: Tallahassee, Florida; Scranton, Pennsylvania; London, Ontario; Lima, Ohio; and Anniston, Alabama.
