They were armed with a battery of twelve 14-inch (360 mm) guns in four three-gun turrets. Tennessee served in the Pacific Fleet for duration of her peacetime career. She spent the 1920s and 1930s participating in routine fleet training exercises, including the annual Fleet Problems, and cruises around the Americas and further abroad, such as a goodwill visit to Australia and New Zealand in 1925

Tennessee was moored in Battleship Row when the Japanese attacked Pearl Harbor on 7 December 1941, which brought the United States into World War II. She was not seriously damaged, and after being repaired she operated off the West Coast of the US in 1942. In 1943, Tennessee and many of the older battleships were thoroughly rebuilt to prepare them for operations in the Pacific War and in June–August, she took part in the Aleutian Islands Campaign, providing gunfire support to troops fighting to retake the islands. The Gilbert and Marshall Islands campaign followed from November 1943 to February 1944, including the Battles of Tarawa, Kwajalein, and Eniwetok. In March, she raided Kavieng to distract Japanese forces during the landing on Emirau, and from June through September, she fought in the Mariana and Palau Islands campaign, bombarding Japanese forces during the Battles of Saipan, Guam, Tinian, and Anguar.

The Philippines campaign followed in September, during which the ship operated as part of the bombardment group at the Battle of Leyte. The Japanese launched a major naval counterattack that resulted in the Battle of Leyte Gulf, a series of four naval engagements. During the Battle of Surigao Strait, Tennessee formed part of the US line of battle that defeated a Japanese squadron; this was the last battleship engagement in history. Tennessee shelled Japanese forces during the Battle of Iwo Jima in February 1945 and the Battle of Okinawa from March to June. During the latter action, she was hit by a kamikaze but was not seriously damaged. In the final months of the war, she operated primarily in the East China Sea, and after Japan’s surrender in August, she participated in the occupation of Japan before returning to the US late in the year. In the postwar draw down of naval forces, Tennessee was placed in the reserve fleet in 1946 and retained, out of service, until 1959, when the Navy decided to discard her. The ship was sold to Bethlehem Steel in July and broken up for scrap.

Authorized in 1890 and commissioned five years later, she was a small battleship, though with heavy armor and ordnance. The ship also pioneered the use of an intermediate battery. She was designed for coastal defense[6] and as a result, her decks were not safe from high waves on the open ocean.

Indiana served in the Spanish–American War (1898) as part of the North Atlantic Squadron. She took part in both the blockade of Santiago de Cuba and the battle of Santiago de Cuba, which occurred when the Spanish fleet attempted to break through the blockade. Although unable to join the chase of the escaping Spanish cruisers, she was partly responsible for the destruction of the Spanish destroyers Plutón and Furor. After the war she quickly became obsolete—despite several modernizations—and spent most of her time in commission as a training ship or in the reserve fleet, with her last commission during World War I as a training ship for gun crews. She was decommissioned for the third and final time in January 1919 and was shortly after reclassified Coast Battleship Number 1 so that the name Indiana could be reused. She was sunk in shallow water as a target in aerial bombing tests in 1920 and her hull was sold for scrap in 1924.
