Lockheed has received a $139.6m contract to provide 44 combat-proven high-mobility artillery rocket systems (HIMARS) to the US Army.
HIMARS is based on the US Army's FMTV truck, and has been designed to launch the entire multiple launch rocket system (MLRS) family of munitions.
The system can accommodate a six-pack of guided MLRS rockets, or one army tactical missile system missile.
HIMARS enables the troops to engage and defeat artillery, air defence concentrations, trucks, light armour and personnel carriers, as well as supporting troop and supply concentrations.
Work on the contract will be carried out at the company's facilities in Arkansas and Texas, US, with deliveries continuing to January 2013.
The US Army, US Marines and several international allies operate HIMARS.
