When the Submarine Voyage attraction was added to Disneyland Park, the Imagineer-designed submarines were constructed at the Todd Shipyards in San Pedro, California. The subs—each one 52 feet long—made the voyage to Walt Disney’s original Magic Kingdom in Anaheim via the Southern California freeways and side streets in April 1959, so they would be ready to dive into liquid space on June 6, 1959.
