The cities of Spokane and Seattle, Washington were targeted by the Soviet Union as part of their daring March 2, 1951 attacks on the U.S. during World War III. The bomber targeting Spokane was shot down. The bomber targeting Seattle actually delivered its bomb between that city and the suburb of Everett, doing damage to both locations.
In the aftermath, the governor called out the National Guard to maintain order in the state. In addition to setting up refugee camps around the state, the National Guard also set up checkpoints on the border with Oregon.
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 Dr. 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 with an explosive-metal bomb not long after Larssen returned to Denver.
