SAN DIEGO (AP) ¿ SAIC Inc. said Thursday it has won a contract from the U.S. Marine Corp. potentially worth more than $120 million over five years for work to combat improvised explosion devices, or so-called IEDs.

SAIC's work will be done in the U.S., Kuwait, Iraq and Afghanistan.

The company will be the program support integrator for the Marine Corps Counter Radio Controlled Improvised Explosive Device Electronic Warfare program, which uses vehicle-mounted, multiband radio frequency jammers. They are designed to block certain radio frequencies and prevent remote detonation of land mines.

The initial order that covers the next year is worth $22 million.

SAIC shares fell 14 cents to $17.68 in aftermarket trading after closing Thursday at $17.82.
