The USAMP Major General Wallace F. Randolph was a notable American mine planter vessel measuring approximately 188.2 feet (57.4 meters) in length. Built by the Marietta Manufacturing Company in Point Pleasant, West Virginia, and launched on June 2, 1942, this ship was originally constructed for the U.S. Army Mine Planter Service, specifically serving the Coast Artillery Corps during World War II. As one of 16 such Army mine planters produced between 1942 and 1943, the vessel was part of a fleet designed for coastal mine-laying operations. The ship's construction featured a robust steel hull suited for the demanding tasks of mine deployment. After her initial military service, the vessel was transferred to the U.S. Navy in March 1951, where she was classified as a Camanche-class minelayer, designated ACM-15, and later reclassified as MMA-15. Although she was assigned a naval designation, she did not see active service and was kept in reserve. Post-naval service, the vessel was sold to civilian owners, renamed Sea Searcher, and repurposed for oilfield exploration. In the 1960s, she played a significant role in lightning research, being fitted with instruments to analyze thundercloud lightning strikes. She was later renamed Thunderbolt, reflecting her exposure to frequent lightning hits during experiments. Finally, the vessel was donated to the Florida Keys Artificial Reef Association and scuttled off the coast of Florida on March 6, 1986, at a depth of 120 feet (37 meters). The wreck, now known as the Thunderbolt Wreck, rests on a sandy bottom and is largely intact, making it a prominent site for advanced divers. Extensive coral growth and abundant marine life, including various fish species and reef sharks, enhance its maritime significance as a vibrant artificial reef and an important site for underwater exploration and research.
