The USS New Jersey (BB-62) provided crucial naval gunfire support in Vietnam, firing its massive 16-inch guns to support Marines, destroy enemy positions in the jungle (like tunnels), clear landing zones, and disrupt North Vietnamese forces, making it the only U.S. battleship to do so during the war, earning its nickname "Big J" for its powerful, accurate, and continuous support, often devastating enemy strongholds. Spotter planes guided shells, allowing the battleship to hit targets deep inland
