About this Unit
USS Yosemite is the name given to several ships in the United States Navy, with the most notable being a converted auxiliary cruiser commissioned during the Spanish-American War in 1898. Originally built as the civilian steamer El Sud, she was quickly outfitted for military service and played a key role in blockading Spanish forces in the Caribbean, particularly around San Juan, Puerto Rico. The ship was praised for her speed and effectiveness in disrupting enemy shipping. Sadly, Yosemite was lost in a typhoon off Guam in 1900, but her brief service was marked by dedication and valor.
