Launched fighter-sized cruise missiles, painted bright orange, attempted to rescue Vietnam War PoWs – these are only some of the things that the USS Grayback was able to do. The USS Grayback is U.S. Navy’s post-World War II submarine with a fascinating and bizarre shape. It was first laid down on July 1, 1954, at Mare Island Naval Shipyard in San Francisco Bay, California, and was the first of its class. It was also the first submarine to carry Vought’s next-generation SSM-N-9 Regulus II, making it a really historical piece that no one can easily forget. Today, the legacy of the submarine is alive by the Navy’s four Ohio class nuclear-powered guided-missile submarines.
