Under the contract, the Cambridge-based nonprofit organization will test, repair and maintain guidance subsystems on the Trident II (D-5) missile.

In addition, Draper will also perform research aimed at applying new technologies to support the Trident II.

The company will perform 94 percent of the work in Andover, Cambridge and Pittsfield, Mass., and the remainder at locations in California and Florida.

The work for the contract is expected to be completed by September 2009.
