Special

Indianapolis — American special premium Tier VII cruiser.

USS Indianapolis, the second cruiser of the Portland class, participated in the New Guinea campaign and the Aleutian Islands campaign during World War II. Later, the ship participated in various landings, including those on Kwajalein, Saipan, and the Mariana and Palau Islands. She also provided cover for raids on Tokyo and took part in the assault landings on Iwo Jima and Okinawa. Tragically, on July 30, 1945, the ship was struck by two torpedoes from a Japanese submarine and sank rapidly. The surviving crew spent several days in the water, even enduring shark attacks. Over the course of World War II, the ship was awarded 10 battle stars.

Indianapolis first went on sale in late May 2016.

Player Opinion

Performance

Warning: The data presented in the AA Defense sidebar section may be incorrect.
Refer to the in-game Port screens for more useful data.

Indianapolis should hold little to no surprises for players who are accustomed to the gunnery style of the American cruiser line. She's a Portland-class ship; a melding of the Pensacola and Northampton classes with an AB-X (two forward and one aft) turret layout. This arrangement becomes the standard for American cruisers at Tier VIII and above, and her guns pack a nasty punch. Add the fact that she shares most of Pensacola’s quick handling characteristics — her top speed and turning radius are identical — and the result is a cruiser that can snipe at destroyers with ease and hold her own in gunnery duels with cruisers above her tier if played well.

As a treaty cruiser like Pensacola and New Orleans, Indianapolis does not hold up to sustained fire well as her World War II brethren, but is noticeably more durable against other cruisers when her bow is pointed towards them. Her anti-aircraft suite is nearly identical to that of her fellow U.S. Navy cruisers in the regular tech tree, with most of her AA punch coming from her medium-range 40mm Bofors mounts. Indianapolis’ ability to mount the Surveillance Radar  consumable gives her an extra leg up on stealthy ships or those concealed by smoke, as not only is she one of a handful of Tier VII ships equipped with radar, but her radar range is equal to that of Tier X's Des Moines (9.9 km).

Played smartly, the utility of Indianapolis’ consumables and main battery guns will significantly contribute towards victory for her team.

Pros:

• Impressive guns for a Tier VII cruiser; her AP shell velocity is similar to Myoko and has better normalization values.
• Longest main battery range of all U.S. Navy cruisers.
• Solid AA suite.
• Superb handling; only slightly slower rudder shift time than Pensacola.
• Can equip the mount the Surveillance Radar  consumable a full tier before ships in the regular tech tree.

Cons:

• Big target.
• Armor is not durable against other cruisers when broadsides are exposed. As with all cruisers, bow armor will not save her from battleships. Overall she won't last long in prolonged firefights.
• Turrets slightly more prone to incapacitations and then being knocked out.

As a premium ship, Indianapolis has no module upgrades to research.

History

Design

USS Indianapolis (CA-35) was the second of two Portland-class heavy cruisers constructed by the US Navy. Under the terms of the 1922 Washington Naval Treaty, she could mass no more than 10,000 long tons; the final design managed to squeeze in at 9,950 tons. Like all treaty cruisers, she was a compromise between armor, speed, and armament.

Indianapolis’ predecessors of the Pensacola class sacrificed armor to achieve the main battery of ten (10) 8-inch barrels and a 32 knot top speed. It wasn’t realized until these ships began entering service in the late 1920’s that they were significantly under treaty weight limitations; subsequently, the Navy’s Bureau of Ships set about addressing the armor inadequacies of the design. Her belt and magazine armor were both substantially increased, and her armament was set at nine (9) 8-inch rifles in three triple turrets.

Service

Laid down on 31 March 1930 at the New York Shipbuilding Company in Camden, New Jersey, USS Indianapolis was commissioned into service on 15 November 1932. She was constructed with facilities befitting flag admirals and their staffs; this gave Indianapolis the unique honor of hosting and transporting President Franklin D. Roosevelt on three separate occasions during the mid-1930s, including state visits to several South American countries in late 1936.

At the outbreak of World War II, Indianapolis was on assignment at Johnston Atoll in the Central Pacific. She was reassigned to Task Force 11, seeing action during the Battle of the Coral Sea and, later, the re-capture of territory in the Aleutian Islands lost to Japan during the Battle of Midway. She reported to Mare Island, California for repair and refit in the summer of 1943; afterward, she returned to Pearl Harbor in August 1943 with a new assignment as the flagship of 5th Fleet under Vice Admiral Raymond A. Spruance.

Indianapolis flew Spruance’s flag for the remainder of 1943 and a significant portion of 1944, shepherding him through victories in the Marshall, Gilbert, and Marianas Islands campaigns. She participated in the Battle of the Philippine Sea and the conquest of islands throughout the Central Pacific, including Iwo Jima and Okinawa.

She was gravely wounded at Okinawa in March 1945 by a Japanese kamikaze attack. When her repairs were completed in July, she was tasked with the top-secret mission of transporting components of the atomic bomb “Little Boy” to the island of Tinian. Indianapolis made the 5,000-mile journey in a record-breaking ten days. She was then ordered on to Okinawa by way of Leyte Gulf. It was to be her final assignment.

In the pre-dawn hours of 30 July 1945, the Japanese submarine I-58 put two torpedoes into Indianapolis. She sank in minutes, dumping more than three-quarters of her 1,200-man crew into the water. No distress call was received by Allied vessels; surviving crew spent more than three days adrift before they were discovered and rescued.

Between dehydration, fatigue, and shark attacks, there were only 316 survivors. Four days after their rescue, “Little Boy” was dropped on Hiroshima, marking the final days of World War II and cementing Indianapolis’ place in history. In August 2017, her wreckage was located in the Philippine Sea, submerged beneath 18,000 feet (5,500 meters) of water and approximately 25 miles west of her last known position.

Historical Inaccuracies

• Indianapolis is depicted in 1944 condition. None of her early refits, including her original 1932 configuration, are represented.
• Indianapolis’ standard late-war Measure 22 camouflage is missing.
• Only one F4F Wildcat was converted into a floatplane and it was fitted with twin floats, not the single float configuration as shown in-game.
• Vought OS2U Kingfisher floatplane is missing. In 1945, Indianapolis was re-equipped with the Curtiss SC Seahawk, which is also missing.
