San Diegos Naval Training Center (NTC) was commissioned on June 1, 1923, and for 70 years served as a young recruits introduction to a naval career, beginning with nine weeks of basic orientation and organization training (BOOT) camp. Originally consisting of 135 acres adjacent to San Diego Bay, NTC eventually expanded to almost 550 acres with 300 buildings, landscaped promenades, parade grounds, and a concrete training non-ship, the USS Recruit (a.k.a. USS Neversail), where recruits learned their first duties of seamanship. Advanced training schools were later added for military personnel learning specialized duties. After training hundreds of thousands of recruits, NTC was officially closed on April 30, 1997, and has since been transformed into San Diegos new and vibrant cultural center, Liberty Station.
