The US Army has awarded a $647m contract to General Dynamics to produce a total of 352 Stryker vehicles.
The Stryker family of vehicles are eight-wheel-drive armoured combat vehicles which can travel at a maximum speed of 60mph on highways, with a range of 312 miles.
Stryker operates with the latest command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) equipment and an integrated armour package to protect soldiers against improvised explosive devices, rocket-propelled grenades and a variety of infantry weapons.
The contract awarded by the US Army TACOM Lifecycle Management Command is part of the initial contract received by General Dynamics in the year 2000 under the Stryker programme.
The US Army's three of seven Stryker brigade combat teams are deployed in combat zones, two in Iraq and one in Afghanistan.
Work will be carried out in the US, the UK and Canada. Deliveries are scheduled to begin in July 2010.
