This flag is flying from the last remaining of the more than 700 Victory ships built during WWII. The Red Oak is docked at the Rosie the Riveter NPS site in Richmond, CA across the bay from San Francisco. This yard built about half of those ships most in a very short time. This ship had many duties during WWII but also served during the Korean Conflict and in the Vietnam era. During Vietnam it ferried high explosive shells across the Pacific.
