Lockheed Martin has won a $318m contract from the US Department of Defense for Hellfire II missile component production.
The components will support the Hellfire II missiles in use with the US army and air force, and in Korea, Egypt, Pakistan, Iraq, India, Saudi Arabia, Tunisia, and Indonesia.
Scheduled to be completed by October 2018, the work will be undertaken in Orlando and Ocala in Florida, and Troy in Alabama.
Hellfire II is a precision-strike semi-active laser (SAL)-guided missile system.
According to Lockheed Martin, the missile defeats advanced armour and urban point targets in the presence of severe electro-optical countermeasures, with minimal collateral damage.
Capable of launching from multiple air, sea and ground platforms, the missiles provide a precision, man-in-the-loop capability.
Hellfire II comes in two versions, high explosive anti-tank (HEAT) for anti-armour requirements and blast fragmentation (BF) for naval targets, buildings and bunkers.
Last week, Lockheed Martin won a $302m contract under the US Joint Air-to-Surface Standoff Missile (JASSM) programme.
The company will be responsible for JASSM production, system upgrades, integration, sustainment, management and logistical support.
The contracts come at a time when the US and its allies stepped up air strikes on the Islamic State of Iraq and the Levant (ISIL).
The US has hit Syria with more than 20,000 missiles and bombs since the air strikes began in 2014.
