Peacetime service with the battleship divisions involved an annual cycle of training, maintenance, and readiness exercises. Her yearly schedule included competitions in gunnery and engineering performance and an annual fleet problem, a large-scale war game in which most or all of the United States Fleet was organized into opposing forces and presented with a variety of strategic and tactical situations to resolve. Beginning with Fleet Problem I in 1923 and continuing through Fleet Problem XXI in April 1940, Tennessee had a prominent share in these battle exercises. However, her individual proficiency was not neglected. During the competitive years 1922 and 1923, she made the highest aggregate score in the list of record practices fired by her guns of various caliber and won the "E" for excellence in gunnery. In 1923 and 1924, she again won the gunnery "E" as well as the prized Battle Efficiency Pennant for the highest combined total score in gunnery and engineering competitions.

After preliminary repairs at Pearl Harbor, Tennessee headed for Puget Sound Navy Yard for permanent repairs.

With the change of naval battles from conventional surface-ship actions to long-range duels between fast carrier striking forces, the older battleships — Tennessee and her kin — were simply too slow to keep up with the carriers. Tennessee spent some time with TF 1, which patrolled areas of the Pacific in the expectation that part of the Japanese fleet might attempt an "end run" raid on the US Pacific coast.

On 1 August, Tennessee again sailed from San Francisco with TF 1. After a week of exercises, the battleships joined on her way to the South Pacific to support the Guadalcanal operation, and escorted the carrier as far as Hawaii. Arriving at Pearl Harbor on 14 August, Tennessee returned to Puget Sound on the 27th for modernization.

Underwater demolition teams (UDT) approached the beach in small craft to reconnoiter the landing beaches and to plant radar beacons which would provide reference points to the next day's landing. Tennessee closed to 3,000 yd (2,740 m) of Agingan Point and opened up with 14 in (355.6 mm), 5 inch (127 mm), and 40 mm batteries.

The battleship commenced counterbattery fire, but the third enemy salvo scored three hits, all of which burst on impact. One projectile knocked out a 5 inch (127 mm) twin gun mount; the second struck the ship's side, while the third tore a hole in the after portion of main deck and sprayed fragments into the wardroom below. An intense fire inside the disabled gun mount was subdued in two minutes by repair parties and men from nearby gun crews; the hit to the hull damaged external blister plating, but was prevented from inflicting further damage by the battleship's heavy belt armor. Eight men were killed by projectile fragments, while 26 more were wounded by fragments and flash burns.

Tennessee's damages did not prevent her from delivering call fire to help break up a developing Japanese counterattack near Agingan Point before leaving the firing line to make emergency repairs.

A prominent masonry lighthouse on the west coast of Angaur was ordered destroyed to keep the Japanese from using it as a gunfire observation point. Twelve 14 in (355.6 mm) rounds were aimed at it, scarring the area and scoring three hits, but the tower remained standing. Other targets absorbed Tennessee's attention for the next three days. Tennessee stood by off Peleliu during the morning of 15 September in case her guns should be needed to assist the assault landing. When this work was completed, she returned on the evening of 16 September to finish off the stubborn tower before the next morning's scheduled landings.

The landings were scheduled for 20 October, and at 0600, Tennessee opened neutralization fire on the beaches. Tennessee continued her work off the beachhead until her fire support was no longer required and the increasing tempo of Japanese air activity in the area required her to place herself where her antiaircraft guns could assist in the defense of the assembled transports and cargo ships.

In the evening of 21 October, while lying dead in the water in a smoke screen laid to protect the shipping from attacking planes, Tennessee was rammed near the stern by the transport . No one was injured, and the battleship's tough hull was little harmed, but her orders for a night fire-support mission were canceled.

Onboard Tennessee, observers had seen distant flashes of gunfire, star shells and searchlights as the torpedo boats and destroyers engaged the Japanese. Soon explosions could be heard. At 0302, the battleship's radar picked up Nishimura'a approach at nearly 44000 yd (40,233.6 m) and began to track the lead ship. This was the flagship, . With the cruiser and the destroyer , she was all that remained of the first Japanese force. At 0351, Oldendorf ordered the flanking cruisers to open fire, and at 0356, the battleships let fly from 20600 yd (18,836.6 m).

Radar fire control allowed the American battleships to hit targets from a distance at which the Japanese could not reply because of their inferior fire control systems, although 6-inch shells from Yamashiro and Mogami crippled destroyer . Japanese ships Yamashiro and Mogami were crippled by a combination of 14 in (355.6 mm) and 16 in (406.4 mm) armor-piercing shells. Shigure turned and fled, but lost steering and stopped dead.

The next several days were quiet ones for Tennessee, though the Japanese sent numerous land-based air strikes against Leyte Gulf. On 29 October, the battlewagon's crew was told that their next destination was to be the Puget Sound Navy Yard. This refit made no remarkable changes in Tennessee's appearance. Her main battery directors received improved models of the Mark 8 radar, and the Mark 4 radars used with the 5 inch (127 mm) gun directors were replaced by the newer combination of paired Mark 12 and Mark 22 dual-purpose equipment. Tennessee's usefulness as an anti-aircraft ship was enhanced by the addition of a model SP height-finding radar.

While Tennessee was being refitted, landings had been made in the Central Philippines and on Luzon; and the liberation of the Philippines was nearly accomplished.

Early on 16 February 1945 the Tennessee's assigned firing course took her along the southeastern shore of Iwo Jima, and her 14 in (355.6 mm) guns struck the slopes of Mount Suribachi while the secondaries aimed at the high ground at the north end of the beach. While the heavier guns fired from ranges varying from 2,200–6,000 yd (2,012–5,490 m), the 40 mm battery raked other targets on cliffs at the north end of the beach and shot up the wrecks of several Japanese ships beached near the shore; these had been used as havens for snipers and machine gunners at Tarawa

 and in later landings, and were always treated as potential threats. Several fires were started ashore; an ammunition dump exploded spectacularly and burned for several hours.

The next morning beginning at 0803, Tennessee, with Idaho and Nevada, closed to 3,000 yd (2,740 m) and began firing. The ships were so close to the shore that at some point the Tennessee was struck by return fire from a Japanese coastal gun on one of her 5 inch (127 mm) guns, which killed Seaman First Class Leon Andrew Giardini and wounded four others. At 1025, the battleships were ordered to the rear to make way for the invasion troops.

It had been found that single-gun salvoes at close range, using "pointer fire" (in which the gun is directly aimed by telescopic sight), were the most precise and effective. The notion of using a 14 in (355.6 mm) naval rifle for sniping was rather new, but it seemed to work very well. Ground fighting on Iwo Jima continued until 26 March, as the stubborn Japanese were slowly rooted out or the positions that they continued to defend to the last. Tennessee was a part of this struggle until 7 March, when she sailed for Ulithi

The Battle of Okinawa, codenamed Operation Iceberg, was fought on the Ryukyu Islands of Okinawa and was the largest amphibious assault in the Pacific War of World War II. The 82-day-long battle lasted from early April until mid-June 1945...

The pattern of life off Okinawa during the grueling weeks to come, as the "fleet that came to stay" battled to see the land battle through while keeping itself alive, consisted of shore bombardment and fighting off kamikaze attacks. Long hours at general quarters kept all hands tense and tired as the ships prowled off the island firing at every likely target while reports of suicide attacks piled up. The island was not secured until 21 June. In the meanwhile, the Navy battled by day and night against the unremitting kamikaze offensive.

On her second day off Okinawa Tennessee was attacked by four planes. The first plane was shot down 5,000 yards from Tennessee's stern. Two minutes later the second plane was shot down 5,500 yards from her stern. Five minutes, later a third plane was destroyed 5 miles away. The fourth plane was fired upon at 5,000 yards away and crashed 12,000 yards off Tennessee's bow.

USS Tennessee was attacked again by airplanes on 1 April and 3 April. These attacks were not suicide attacks. The first kamikaze attack came on 6 April. Tennessee fought off six kamikazees. On 7 April, a single kamikaze attacked Tennessee. Five days later, Tennessee faced the strongest kamikaze attack yet.

On the afternoon of 12 April, Tennessee, instead of taking up a fire-support station, was steaming in air-defense formation. Five kamikazes picked Tennessee and came in through puffs of shell bursts and the heavy smoke from the burning destroyer . Four were shot down, the last three only hundreds of yards from the battleship. The last diver came down on the bow at a 45° angle, was set aflame by 5 inch (127 mm) fire, and plunged into the water. At the same time, an Aichi D3A

 "Val" dive bomber, flying low on the starboard bow, headed directly for Tennessee'ss bridge. Lookouts spotted the "Val" at 2,500 yd (2,290 m), and every automatic weapon that could bear opened up. One of the plane's fixed wheels was torn off, and its engine began to smoke.

Heading at first for Tennessees tower foremast, the Japanese pilot swerved slightly and crashed into the signal bridge. The burning wreck slid aft along the superstructure, crushing anti-aircraft guns and their crews, and stopped next to Turret Three. It had carried a 250 lb (110 kg) bomb which, with what was left of the plane, went through the wooden deck and exploded. Twenty-two men were killed or fatally wounded, with another 107 injured. This was not enough to put Tennessee out of action. The dead were buried at sea, and the wounded transferred the following day to the casualty-evacuation transport . The ship's company turned to on emergency repairs; and, by 14 April, the ship was back on the firing line. Tennessee remained off Okinawa for two more weeks.

On 1 May, Admiral Deyo shifted his flag to a cruiser, and Tennessee set her course for Ulithi. Here, the repair ship made repairs, cutting away damaged plating and installing new guns to replace those lost. On 3 June, the ship sailed for Okinawa, arriving on 9 June. By now, the worst was over. Army troops were making a final drive to clear the island, and Tennessee's gunfire again helped to clear the way. With the other old battlesips, she remained in support until organized resistance was declared at an end on 21 June.

The Tennessees battery, counter battery, and fire support played a major role in the success of the invasion of Okinawa as reflected by the messages passed through the chain of command from COs on the ground to Tennessee. On 18 April, Rear Admiral Reifsnider, commanding Task Group 51.12, told Captain Heffernan:

"Today our troops took the high ground prepared by the Tennessee yesterday. Seven enemy were killed on the slope and 30 on the top in huge craters caused by the Tennessee... counted 120 enemy dead and numerous demolished antiaircraft weapons and installations. C.O. Headquarters, 6th Marine Division, himself saw the Tennessees fire yesterday and wishes to express his appreciation for the Tennessee's cooperation and delivery of outstanding support. The main and secondary batteries of the Tennessee broke and drove the enemy back. Her naval gunfire on the almost impossible did the job. Congradulations to all the men of the Tennessee."

On 26 April, Rear Admiral Hall, TG 51.22 CO, informed Admiral Deyo of a message from
Headquarters, U.S. 27th Infantry Division, which read:

"Performance of all firing ships... excellent. We would like to see them have their just compensation and reward, especially the Tennessee."

Vice Admiral Oldendorf was subsequently placed in command of naval forces in the Ryukyus, and Tennessee flew his flag as she covered minesweeping operations in the East China Sea and patrolled the waters off Shanghai

Philadelphia Naval Shipyard
The Philadelphia Naval Business Center, formerly known as the Philadelphia Naval Shipyard and Philadelphia Navy Yard, was the first naval shipyard of the United States. The U.S. Navy reduced its activities there in the 1990s, and ended most of them on September 30, 1995...

. During those years, she had fired 9,347 14-inch rounds at the enemy, with 46,341 shells from her 5-inch guns and more than 100,000 rounds from her antiaircraft battery.

Post war and beyond

The process of trimming the wartime Navy down to postwar size was already well underway. Tennessee was one of the older, yet still useful, ships selected for inclusion in the "mothball fleet
Reserve fleet

"; and, during 1946, she underwent a process of preservation and preparation for inactivation. The work went slowly; there were many ships to lay up and not enough people to do it. Finally, on 14 February 1947, Tennessees ensign was hauled down for the last time as she was placed out of commission.

Tennessee remained in the inactive fleet for another 12 years. By then, time and technology had passed her by; on 1 March 1959, her name was struck from the Naval Vessel Register

Awards

On 13 October 1945 Vice Admiral Jesse B. Oldendorf announced to the crew that he had recommended the USS Tennessee for a Unit Citation which would be the equivalent to the Silver Star or Legion of Merit awarded to individuals. This is one of only two Navy Unit Citations awarded to a Battleship for actions during World War II. The citation was signed by Secretary of the Navy James Forrestal on 5 April 1946.

All personnel attached to the Tennessee and actually present and serving during the period of 31 January 1944 through 21 June 1945 in the Pacific, or any part thereof, earned a Navy Unit Commendation

. The commendation awarded USS Tennessee reads as follows.
U.S.S. Tennessee (BB-43) Navy Unit Commendation
The Secretary of the Navy takes pleasure in commending
The United States Ship Tennessee for service as follows:

"For outstanding heriosm in action against enemy

Japenese forces during the period from January 31,

1944, to June 21, 1945. Conducting extensive bom-

bardments with devistating accuracy throughout thir-

teen major operations, the U.S.S. TENNESSEE method-

ically reduced enemy defenses prior to the time of

landings, provided a tremendous amount of concen-

trated fire directly covering amphibious assaults, and

furnished controlled fire supporting the movement of

troops ashore after the invasions, making possible the

advance of our forces through the Central Pacific with-

out prohibitive loss of life. Withstanding repeated

blows from enemy shore batteries, bombs, torpedoes

and Kamikaze planes, her courageous crew skillfully

effected emergency repairs which kept her in action

during extended periods of tension, strain and extreme

peril. In the historic Battle of Surigao Straits she con-

tributed materially to the destruction of a powerful

portion of the Japanese Fleet, including at least two

battleships. The TENNESSEE's splendid record of

achievements, from the Aleutians to the Ryukyus, re-

flects the superb teamwork and gallantry of her valiant

officers and men and is in keeping with the highest

traditions of the United States Naval Service."



All personnel attached to and serving on board the

U.S.S. TENNESSEE during the above period are hereby

authorized to wear the NAVY UNIT COMMENDATION Ribbon.
