Raytheon, in announcing the award, said the fire units for the Patriot system feature advanced technology and upgraded man-machine interface.
Work on the units for Taiwan will be conducted at company facilities in Massachusetts, Texas and Alabama.
Raytheon didn't disclose a delivery schedule for the products.
In 2008, Raytheon was contracted to upgrade Taiwan's existing Patriot systems and was contracted the following year to provide new Patriot systems. It also delivered a Configuration-3 upgraded radar system to Taiwan this year.
"Raytheon's excellent performance for this customer on current and past contracts continues to drive trust, as we deliver superior technology and support for Taiwan's protection," said Sanjay Kapoor, vice president for Integrated Air and Missile Defense at Raytheon's Integrated Defense Systems business.
