Service Craft San Diego YTL-560 59-60; USS Mispillion AO-105 60-61

**Service Craft San Diego YTL-560 (1959-1960):** YTL-560 was a yard tug assigned to Service Craft San Diego in the late 1950s. Throughout 1959 and 1960, it provided essential harbor services such as towing, docking, and maneuvering ships within the busy naval facilities of San Diego, California. The tug played a vital role in supporting the operational readiness of larger fleet units by ensuring the efficient movement of vessels in the harbor. **USS Mispillion (AO-105) (1960-1961):** Commissioned in 1945, the USS Mispillion was a Cimarron-class fleet oiler. During 1960-1961, she continued her mission of underway replenishment in the Pacific, supplying fuel, lubricants, and stores to ships of the U.S. Navy. This support was critical during the Cold War era, enabling extended fleet operations and maintaining American naval presence in strategic waters. Mispillion’s service in these years demonstrated the indispensable role of oilers in power projection and fleet sustainability.
