USS Shasta (AE-33) was a Kilauea-class replenishment ammunition ship of the United States Navy. She was named after Mount Shasta, a volcano in the Cascade Range in northern California. Shasta's mission was to support forward deployed aircraft carrier battle groups, which she accomplished through underway replenishment (known as unrep) and vertical replenishment (known as vertrep). Over three decades, Shasta and her crew took part in the Vietnam War, the Cold War, the Iran-Iraq War, Desert Shield/Operation Desert Storm, and numerous other actions.
