From the 1950s, United States Fleet Activities Yokosuka has been home port for the United States Seventh Fleet, and played a critical support role in the Korean War and the Vietnam War. Yokosuka was the site of many anti-war protests during the late 1960s and 1970s. The nuclear-powered USS "George Washington", formerly based at Yokosuka, was the first U.S. nuclear-powered ship that had been permanently based in Japan. The Japan Maritime Self-Defense Force also operates a military port next to the American base, as well as numerous training facilities at scattered locations around the city. For those reasons, there are a few hundred Americans and a thousand Filipinos in Yokosuka.
