Hanford, Washington was the site of the United States' superbomb project during the Second Great War. Confederate pilots bombed Hanford in an attempt to destroy the project, but the attack proved inconsequential. Unable to launch a second air raid due to increased U.S. fighter presence, the Confederates landed a commando team by submersible for a suicide mission. The team succeeded in launching a mortar attack which caused some damaged but did not appreciably slow the U.S. efforts.
Washington was left relatively untouched in the early stages of the Race Invasion. After the Americanatomic bomb project was moved to Denver, Colorado, the scientists soon realized that Denver didn't have sufficient water resources to build the bomb in a timely fasion. The government turned to Washington state, specifically Hanford. General Leslie Groves sent Jens Larssen to Washington to determine if Hanford was a fit site. Upon his return, however, officials decided that moving the project would be too risky. That proved fortunate, as the Race destroyed Seattle not long after Larssen returned to Denver.
