The USS Henry W. Tucker was in commission in the US Navy from 1945 to 1973 and saw service in World War II, the Korean Conflict, the “Cold War” and Vietnam. Through much of her career she was a DDR (Radar Picket Ship) and was involved in many activities, such as the atomic bomb tests in the Pacific, the NASA Apollo program, and the U-2 flights. in 1973, she was decommissioned and sold to the Brazilian Navy and became the Marcilio Dias D25. She was in commission in Brazil from 1973 to 1992. After nearly 50 years continuous service, she was decommissioned and was sunk in target practice by a torpedo of Brazilian design fired from a submarine of Brazilian design, which was an historic event. One of her officers sent us a newspaper article and photos of the sinking. To see the photos and a translation, please click here. Thanks to Mike McDermott (LTJG, 68-69) for translating the article from Portuguese to English. Click on “history” at the top of any page to view the history.
