US Navy Small Craft Training Centers (SCTC) were United States Navy training bases used to train sailors in the operation of the many small wooden crafts used in World War II. These crafts were given the nickname Splinter Fleet. There was a shortage of steel and steel shipyards during World War II, so there was a need for a vast wooden fleet of crafts. The Small Craft Training Centers had classrooms and crafts for training. The bases had barrack housing and mess halls. To get the men and crafts out into the field quickly, at many of the bases men trained on new ships. The new ships were at the center for about 4 weeks as part of the vessel's sea trial.[1][2][3] Tugboats, Minesweepers, Net laying ships, Crash boats, PT boats and other crafts built near the center were taken to the Small Craft Training Centers for testing. Crafts built at Lynch Shipbuilding in San Diego, California were taken to the Small Craft Training Center at Terminal Island, San Pedro, California for their sea trial.[4][5] Lynch Shipbuilding built tugboats, and minesweepers. Some of the craft at the Terminal Island school were: USS Density (AM-218), USS Waxsaw (AN-91), and USS Climax (AM-161), USS Wateree (ATF-117), USS Quest (AM-281), USS Snowbell (AN-52). The US Navy also had Small Craft Training Centers in Miami, Florida, Santa Barbara, California, New Orleans, Louisiana and other sites.[6][7]
