The WW2 USN heavy cruisers blueprint

The Wichita directly inspired the wartime Baltimore class design

Design History

Secretary of the Navy, Curtis D. Wilbur wanted a new construction program for light and heavy cruisers and obtained the Cruiser Act of 1929, authorizing new cruisers, five heavy to the sense of the Washington treaty. In this list, the first four were ordered in 1931-33, of the New Orleans class, and the last was USS Wichita ordered in 1934, as permitted under the London Naval Treaty in 1930: The US indeed was capped to 18 heavy cruisers of 10,000 long tons. The British reached that limit with their County-class and the two York class, dropping the Surrey class because of the same treaty.

Wichita was originally intended as an improved New Orleans class, the design went through several waves of deep redesigns before construction, and she was modelled on the contemporary Brooklyn class "light" cruisers instead. It looked like superficially indeed as a Brooklyn with heavy artillery. But in reality, the ships' hull was given higher freeboard, better stability, and better range.


The Brooklyn class as built, general appearance (author's illustration)

The secondary battery (eight single 5-inch guns) was standard, but arranged in such a way to give them the best fire arc and fields of fire possible. Also, the main battery standardized since the Northampton in triple turrets benefited from a brand new turret design, making the sum of previous problems and fixes detected on earlier turret designs. As the last heavy cruiser, USS Wichita was conceived as the pinnacle of the genre, a provision for new series in case of war. That's exactly what's happened: Wichita is considered in the lineage and the direct forerunner of the wartime Baltimore class, freed from all limitations.

Design

General characteristics

Wichita was 600 feet (182.9 m) long at the waterline and 608 ft 4 in (185.42 m) overall, versus 185 m oa (606 feets) for the Brooklyn, 61 ft 9 in (18.82 m) in beam versus (19 m (62 feets)), and 23 ft 9 in (7.24 m) draught versus 7 m (23 feets), again, on the Brooklyn. She therefore was shorter and nimbler, but with a higher draft. The hull was therefore certainly not the same despite an overall similar appearance. Both ships had indeed a squarish stem with the hangar and catapult at the rear, two cylindrical raked funnels placed right after the main bridge. The latter comprised two four levels. Two main tubular masts, also raked, were placed exactly like for the Brooklyns.

However USS Wichita displaced 10,589 long tons (10,759 t) standard and 13,015 long tons (13,224 t) full loaded and combat ready, versus 9,767 long tons standard and 12,207 long tons fully loaded, so despite reduced dimensions she was actually heavier. One explanation was the larger and deeper ammunition wells and barbettes fo the main turrets and their heavier weight to be compensated. A clear focus was placed on stability.
Her crew comprised 929 officers and enlisted men.

Powerplant

Wichita was propelled by four shafts, activated by four Parsons steam turbines, fed by eight Babcock & Wilcox oil-fired water-tube boilers. The powerplant was rated at 100,000 shaft horsepower (75,000 kW). Top speed was 33 knots (61 km/h; 38 mph). Again, compared to the contemporary Brooklyns, this was about the same powerplant, but the latter were slightly slower, at 32.5 knots (60.2 km/h; 37.4 mph), in part due to the slightly narrower hull and better lenght-to-width ratio.

For her autonomy, USS Wichita carried 1,323 to 1,984 long tons (1,344 to 2,016 t) of fuel oil. This allowed them a range of 10,000 nautical miles (19,000 km; 12,000 mi) at 15 kn (28 km/h; 17 mph), the same figures as the Brooklyns.

Armour

Hull protection at the waterline comprised an armored belt made of Class A hardened steel plates 6.4 in (160 mm) in thickness amidships, reduced to 4 in (100 mm) on both ends. It was backed by a .63 in (16 mm) specially treated steel plating. Class A steel was an improvement on the Class B plates of previous cruisers. Indeed, a heavy cruiser protection was to suffice to defeat a 8-inch round fired from 10,000 yards (9,100 m). Class B armor was only capable of 16,400 yd (15,000 m).

In addition, USS Wichita had a single armoured deck over machinery and ammunition storages, made of a layer of 2.25 in (57 mm) thick plating immune to 8-inch rounds within 22,000 yd (20,000 m). The conning tower was walled by 6 in (152 mm) plates, topped by a 2.25 inches thick roof. The main turrets had faces 8 in (203 mm) thick, 3.75 in (95 mm) sides, and back protected by 1.5 in (38 mm). The turret roof was 2.75 in (70 mm) thick. Their barbettes had walls 7 in (180 mm) thick.

Compared to this, the Brooklyn's protection was significantly lighter: The belt was ranging from 2in (51 mm) to 5 in (127 mm) while the turrets faces were protected by 6 in (152 mm), and the CT had 5 in walls (127 mm), while the armored deck was also thinner at 2in (40 mm). This protection was meant to defeat 6-in rounds.

Armament

Wichita's main artillery

comprised nine 8-inch/55 Mark 12 guns. They were mounted in three triple turrets, two superfiring forward, one aft. These Mark 12 models fired a 335-pound (152 kg) shell at 2,500 feet per second (760 m/s) muzzle velocity. They could elevate to 41 degrees, allowing them a maximum range of 30,050 yd (27,480 m). The average rate of fire of these guns was one shot ever 15 seconds (4 rpm). The space between the guns not only allowed individual elevations and fire, but reduced shell dispersion. Both the range and hitting power were superior to the 6-in, limited to 26,100 yards (23,866 m), but the Brooklyns could fire two volleys for one of the Wichita. Their 6-in/47 caliber Mark 16 were indeed able to deliver 10 rpm in sustained fire, a total of 150 rpm.

To bring the best of long range gunnery spotting, and reconnaissance well beyond the range of radars, the Wichita could launch a small squadron of four seaplanes of the Vought OS2U Kingfisher type (likely). They were launched from aircraft catapults located on the sides of the poop aft, lifted by an axial crane at the stern. They were usually mounted on the catapults buy the hangar was large enough to accommodate all four and was fitted with repairs and maintenance workshop.

Secondary battery:

USS Wichita was the first USN ship armed with the new 5-inch/38 Mark 12 dual-purpose artillery. These were eight, all in single mounts, half mounted in enclosed Mark 30 high-angle turrets similar to those of destroyers like the Fletcher class (unlike the Brooklyns) while four remained in open mounts. Disposition was different from the Brooklyns also: To maximize their arc of fire, two of the enclosed turrets were placed on superfiring positions fore and aft, and the two remaining were abreast the bridge also on raised platforms. The remainder four open mounts were placed like the Brooklyns, on the deck, abreast the rear boats deck between the after bridge and funnels.

These 5-in guns fired a 55 lb (25 kg) shell, at 20 rounds per minute and 2,600 ft/s (790 m/s) muzzle velocity. For AA fire, their ceiling was 37,200 ft (11,300 m) at 85° angle, whereas they could engage surface targets distant of 18,200 yd (16,600 m) at 45 degrees. Beyond, fire was inaccurate. And that was it. There was no lighter AA guns, even the 28 mm "Chicago Piano" or 0.5 cal. Browning models for close range.

Anti-aircraft upgrades

During the war, especially towards 1944, sixteen Bofors 40 mm guns were added to the ship, four in quadruple mounts, and eight in dual mounts. The first were placed on elevated platforms either side of the superstructures abreast the mainmast and foremast, while the twin mounts were located either side of the forward superfiring 5-in gun, behind "B" turret, and the remainder two were located right at the stern, to gain the best arc of fire possible.



Also eighteen Oerlikon 20 mm in single mount, shielded, were also mounted wherever space was available, mostly on the deck, two aft, between the aft quad Bofors platform and 5-in, four in a "balcony", platform abreast the two funnels, and on deck, and two more abreast the bridge also on deck, and two forward at the bow deck. The 40 mm Bofors ceiling was 22,800 ft (6,900 m) at 90° and around 160 rounds per minute, largely depending on the skills of the loaders. The 20 mm had a higher, 465–480 rpm rate of fire due to the gun being belt-fed. They could reach a plane 10,000 ft (3,000 m) high, but their main purpose was last-ditch defense, at very close range. In August 1945, many specific fire control systems were added for these, notably the ubiquitous Mark 34 model for fire control and the Mark 13 and Mark 28 FCS radars.

The USS Wichita in action

Launch of the Wichita in November 1937 at Philadelphia NyD: Scr Navsource

USS Wichita was laid down at the Philadelphia Naval Shipyard on 28 October 1935, to be launched on 16 November 1937. Completion came in February 1938, and at that ime, she was so close to the 10,000-ton limit that it was decided to complete her with only two of heir eight 5-in guns. Later, this was normalized, and she received all expected 5-inch guns, but she was found top-heavy. 200.4 long tons (203.6 t) of pig iron were welded into her bottom and she commissionedon 16 February 1939, one year after her completion, under command of Thaddeus A. Thomson.

Training on the east coast

For her first service trip, she departed Philadelphia for Houston, Texas, arriving on 20 April 1939 for a memorial service at the San Jacinto Battle Monument. She left for her first shakedown cruise, visiting the Virgin Islands, Cuba and the Bahamas. She was back to Philadelphia for modifications and maintenance, and on 25 September, she joined Cruiser Division 7, Atlantic Squadron at Hampton Roads. Her first neutrality patrol started 4 October, as the war raged in Europe.

She spent some time in drydock in maintenance at Norfolk Navy Yard until 1 December, and departed for Guantanamo Bay (Cuba), to the Caribbean Patrol, teaming with USS Vincennes, 5 destroyers, and two Navy patrol squadrons. For three months, training and patrols in the Caribbean went one, until February 1940, as USS Wichita was back to Norfolk, training until May 1940.

In June she teamed up with USS Quincy to make a goodwill cruise to South America, hosting Rear Admiral Andrew C. Pickens, Cruiser Division 7 commander. Ths cruisers stopped at Rio de Janeiro, Santos, Buenos Aires, Montevideo, and were back in September 1940 to Norfolk. For the next three months, USS Wichita trained the Naval Reserve midshipmen, making gunnery exercises off the Virginia capes, and in January 1941, joined Guantanamo for fleet manoeuvres in the Caribbean, covering a mock landing at Puerto Rico. On 23 march she was back for maintenance at the New York Navy Yard, until 6 April, where she sailed to Bermuda to escort the USS Ranger and cruiser USS Tuscaloosa for a North Atlantic patrol up to the coast of Ireland.

Icelandic operations (Summer 1940)

Back to New York Navy Yard in May 1940, she stayed in drydock until 2 July, after which she departed for Newport, Rhode Island. On 27 July she sailed to Iceland (joining Task Force 16) for Operation Indigo II, Iceland occupation by US troops. On 6 August she was in Reykjavik, escorting the carrier Wasp and battleship Mississippi. TF16 landed troops and a fighter Sqn after which the force was back home on 20 August. USS Wichita would make another trip to Iceland in September 1940.

However at that time, the battle of the Atlantic was in full swing and a state of "quasi war" existed with Germany as many US Ships did not hesitated to fire on and sunk U-Boats in their territorial waters and escort ways. USS Wichita therefore was soon assigned to TG 7.5 patrolling Icelandic waters, and this until December 1941. The day after Pearl Harbor, USS Wichita was at anchor in Hvalfjörður, and she left on 5 January 1942 for patroling the Denmark Strait, the back to Hvalfjörður. During her next sortie she was caught on 15 January in a powerful winter storm with winds of 80 knots, gusts up to 100 knots and she was damaged, colliding with the freighter West Nohno and British trawler Ebor Wyke, later running aground off Hrafneyri.

Her crew evaluated the hull and saw she had only suffered minor damage and had some leaks resulting from the grounding. After temporary repairs she sailed to New York Navy Yard in February, and repairs lasted until 26 February. She made a training cruise off Maine in March 1942, and on the 26, assiged to Task Force 39, assisting the Royal Navy.


USS Wichita at Casablanca, 8 November 1942, Operation Torch

North Atlantic operations (April-June 1941)

Wiwhita was based at the British Home Fleet base, Scapa Flow. TF 39 (Rear Admiral John W. Wilcox) also comprised the carrier USS Wasp, battleship USS Washington, and the cruiser Tuscaloosa, in addition of Wiwhita, plus eight destroyers. Wilcox fell overboard in heavy sea and was later replaced by Rear Admiral Robert C. Giffen. He raised his mark on Wichita and TF 39 spend weels training with the British. On 28 April, USS Wichita started her first Arctic convoys escort mission, watching the QP 11 and PQ 15. She was part of TF 99 (Washington, Wichita, Tuscaloosa, four destroyers) and was assisted by the aircraft carrier HMS Victorious, battleship King George V, a cruiser and five destroyers. After this, USS Wichita returned to Hvalfjörður in May.


USS Wichita in Scapa Flow, April 1942

On 12 May, Wichita relieved Tuscaloosa off the Denmark Strait, later escorting the Murmansk-bound convoy PQ 16/QP 12. On 29 May she was in Scapa Flow, hosting King George VI on 7 June. She left Scapa on 12 June for Hvalfjörður, relieving HMS Cumberland on patrol in the Denmark Strait, spotted and fired (but missed) on two Focke-Wulf Fw 200 Condors patrol planes of the Luftwaffe.

At the end of June, she was at Seidisfjord, meeeting Tuscaloosa and three destroyers to escort PQ 17, also escorted by HMS Duke of York. For once, KMS Tirpitz escorted by three heavy cruisers made a sortie, codenamed Rösselsprung, which was known through Swedish intelligence and the admiralty fatefully ordered the convoy to disperse while the Germans aborted the operation. The scattered convoy fell to U-Boats and aviation, loosing 21 of the 34 ships. Both Wichita and Tuscaloosa would also fire Fw 200s, but again, missed. They were just too high to be shot.

In late July, USS Wichita was in drydock at Rosyth in Scotland. This included fixing the shaft vibration. On 9 August, the ship went on trials, showing the problem was still there, and she departed for the United States, New York Navy Yard where she arrived on 22 August, drydocked until 5 September 1942. She then trained in the Chesapeake Bay, Virginia Capes and Casco Bay (Maine).

Operation Torch (Nov. 1942)

Duelling with Jean Bart at Casablanca

Fall October, Wichita joined Task Group 34.1 (Rear Admiral H. Kent Hewitt, USS Augusta) also including USS Massachusetts and her old "sea pal", USS Tuscaloosa. This force was to provide cover fire for Operation Torch, the invasion of Vichy-held French North Africa. USS Wiwhita in this occasion was part of the Battle of Casablanca, a gunnery duel which started in the morning of 8 November, trying to silence the coastal artillery at El Hank, tracking and sinking French submarines, and even duelling with the Jean Bart, at anchor in the harbor incomplete.

She had one turret operational and with it, fire on the US Task Force. Wichita and Tuscaloosa silenced El Hank forst, ruined submarine pens in the harbor while USS Massachusetts took car of Jean Bart, but they also soon had to deal also with the cruiser Primauguet. The Vichy French launched two attacks, the first with destroyers. Both Wichita and Tuscaloosa claimed serious hits on the destroyer Milan, which ran aground. The second attack was repelled, and agiain, both cruisers claimed the destroyer Fougueux and Frondeur.

Wichita, Tuscaloosa, and Massachusetts afterwards engaged Jean Bart, and by 11:28, USS Wichita was framed and hit by a 194 mm (7.6 in) shell from El Hank, they believed was silenced. The hit cost fourteen men and captain Hewitt broke off and return at 13:12, to combine fire on French ships trying to exit the harbor. Wichita and Tuscaloosa engaged at this occasion the cruisers Primauguet and Gloire while El Hank redouble fire, forcing both US cruisers to retreat after 15:00. As far as Wichita was concerned, the battle was over and she spent the next weeks patrolling between Casablanca and Fedhala and she returned to New York for repairs on 19 November.

Pacific theater

Shortly after that, the situation in the Pacific was bad enough that the admiralty chose to sent the cruiser to Task Force 18 (Rear Admiral Giffen), straight to Guadalcanal. There, she teamed with USS Louisville and Chicago, light cruisers USS Montpelier, Cleveland, and Columbia, escort carriers Chenango and Suwannee plus eight destroyers.

Night Battle 29-30 January 1943 off Rennell Island:
As Japanese submarines has been signalled by Allied intelligence the force was spread and organised for anti-submarine defense in two columns 2,500 yard apart. Wichita led the column with Chicago, and Louisville and six destroyers formed a 2 miles semicircle ahead, and... the attack came from Japanese torpedo bombers. The Battle of Rennell Island saw USS Chicago hit by airborne torpedoes, sinking. USS Wichita had more luck. She was hit only by one, which was a dud. She next steamed to Efate (New Hebrides) for maintenance and training and on 7 April sailed for Pearl Harbor.

Operations in Kiska and Attu
After taking onboard supplies she sailed to Adak, Alaska uder Giffen's command, TF 52.10. By May, USS Wichita covered the landings in the Aleutian Islands, as flagship, northern force, with USS Louisville and San Francisco. On 6 July she shelled Japanese positions on Kiska and by July the Japanese started to evacuate. On 19 July she was joined by the USS New Mexico, Idaho, and Mississippi for another three days of preparation on Kiska. During this time, early radar caused glitches, leading to the infamous "Battle of the Pips", all the ships present firing a thousand rounds on empty sea, before confirmation by a plane there was nothing there. Meawnhile the Japanese evacuated the island and when the landing came, there was no fighting.

Marshall invasion (January 1944)
Wichita was back in Hawaii for exercises until the end of the year and on 16 January 1944, she was assigned to the Force gathered to invade the Marshall Islands. This was Task Group 58.3 (Rear Admiral Frederick C. Sherman) comprising the USS Bunker Hill, cruisers USS Cowpens and Monterey, the BBs North Carolina, Massachusetts, Alabama, and South Dakota while Wichita, rearmed in between with her full complement of Bofors and Oerlikon guns, was to provide AA support. The carriers launched air strikes on Kwajalein and Eniwetok and in February.

Pacific operations Truk, Saipan, Guam
Wichita sailed to Majuro, transferred to TF 58.2, sailing for Operation Hailstone, a major air raid on the IJN base at Truk, but soon before it was launched during the night of 16 February, USS Intrepid was attacked by Japanese bombers and badly damaged. TF 58.2.4 was detached to escort Intrepid out of harm, and they were in Majuro on 20 February, then Hawaii. on March, 9, USS Wichita became flagship of Cruiser Division 6, which departed Hawaii for Majuro, screening the Fast Carrier Task Force raiding Yap, Woleai, and the Palau islands. Wichita also covered a raid on Hollandia (New Guinea) by 13–22 April and Truk until the end of April, shelling Japanese targets on Satawan Island and Nomol (Caroline).


Wichita underway in the Pacific, in May 1944

On 4 May 1944, USS Wichita was back to Majuro for supply, rest and training. In June she was sent to Kwajalein for an operation against the Mariana Islands with TF 53.10.8. On 13 June she covered landings at Saipan, then Guam and Saipan again, before assignation to Task Group 58.7, west of the Marianas to try to intercept a large Japanese carrier force, which became the Battle of the Philippine Sea. Wichita AA screen claimed two Nakajima B5Ns, and she was detached to escort troop transports and escort carriers off Saipan, a duty maintained until early July, and she later joined TU 53.18.1 bombarding Guam.

On 10 August she escorted a fleet to Eniwetok and later joined TG 38.1., escorting the fast carrier task group on Palau, the Carolines, Philippines, and Dutch East Indies, Palau and Morotai until mid-September. At 07:34, 22 September, USS Wichita was caught in an air attack, and downed two bomber, damaging others and providing AA cover during raids on Cebu, Negros, and Coron.

Operations off the Philippines

USS Wichita raided Okinawa on 10 October, and later Aparri on Luzon, Formosa, preparing landing in the Philippines. On 13 October 1944 her task force was attacked by Japanese bombers, which nearly sank HMAS Canberra, towed to safety by USS Wichita and later protected the equally badly damaged USS Houston. By 21 October, USS Wichita was off Luzon with Task Force 34 (Vice Admiral Willis A. Lee), soon engaged in the largest naval battle of WW2.

Battle of Leyte Gulf

Wichita took part indeed in the Battle of Leyte Gulf from 23-25 October. She covered the Fast Carrier Strike Force north, pursuing Jisaburō Ozawa own decoy fleet of empty carriers. USS Wichita covered the carriers which took care of the Japanese carriers and later, USS Wichita and three cruisers sank the light carrier Chiyoda, and her escort the destroyer Hatsuzuki. Her AP shells rained down, 148 rounds expended on Chiyoda, 173 against Hatsuzuki. She later screened for the carriers off Samar. On 28 October, and covered landings on Leyte, fending off two days after a massive Japanese airstrike.

On 31 October, Wichita sailed to Ulithi, reaching the island on 2 November doe supplies and well-deserved rest. She would return to Leyte, until mid-November, but the worn-out engines showed their limits as severe vibrations in the No. 4 engine led to a broken propeller shaft, so she sailed on 18 November for San Pedro, California, she reached on 15 December, repaired at Terminal Island NYd. On 8 February 1945 she left, made a shakedown cruise and some training before she was assigned for a new task late February, reaching Pearl Harbor before joining Ulithi.

Invasion of Okinawa (March-May 1945)

USS Wichita all guns blazing at Okinawa

USS Wichita joined at Ulithi Task Force 54, the force planned for the invasion of Okinawa, and more precisely she was tasked to protect TFU 54.2.3, minesweepers off operating in the waters of Okinawa from 25 March. A day after she shelled Japanese positions from 13:50 to 16:30, being attacked by aircraft, claiming one. Her shelling missions went on until 28 March, retiring shortly to Kerama Retto for supplies, and later covering underwater demolition teams clearing bthe beach from obstacles. She also targeted the sea wall to create a breach.

On 1 April trooped landed under Wichita close support gunfire, leaving around midday to replenish ammunition and back again, also covering minesweepers. She then joined Task Group 51.19, prepared to shell Tsugen Shima with Tuscaloosa, Maryland and Arkansas, operation cancelled because a Japanese air attack. Wichita instead turn her guns against the shore batteries at Chiyama Shima. On 6 April, an A6M Zero Kamikaze targeted Wichita, and her anti-aircraft gunners soon hit the Zero's tail which dropped its 500-pound (230 kg) bomb only 50 feet (15 m) from the hull, while its wing clipped the deck before chashing. Eleven men were wounded. Wichita was detache dlater to silence a battery at Nakagusuku Bay and went on bombarding Japanese defenses until departing on 10 April for supplies.

On 27 April, the cruiser took a hit (light shell) in her a fuel oil tank below the waterline but was temporarily repaired, then departed for more repairs at Kerama Retto, on 29–30 April. On 12 May, while still covering the landings, she was damaged by friendly fire, a 5-inch round damaging her port aircraft catapult and AA director. She was refitted at Leyte and was back for more operations in June and July, with TF 2. On 15 August, her crew learned the war was over and her crew won 13 battle stars.

Post-War service

Nagasaki, September 1945

Wichita was part of the escort of the occupying force and was by September in Nagasaki with TG 55.7, one on the first large US warships to enter Japanese waters. She was the flagship of a small force comprising destroyer escorts, minesweepers, and the hospital ship Haven. By late September she was in Sasebo and back to Nagasaki, then back again to Sasebo when she was hit by a severe typhoon. Later her crew inspected Japanese ships present and harbor installations.

On 5 November, the cruiser took part in Operation Magic Carpet, repatriation of American military personnel and doing her first trip, from Tokyo to San Francisco, reached on 24 November 1945. She entered drydock at Mare Island, until 1 December, and she resumed the repatriations trips from Pearl Harbor to the Marianas, Saipan and back to San Francisco. The next year she reached Philadelphia via the Panama canal on 14 February, assigned to the Sixteenth Fleet but in reserve by July 1946, and finally decommissioned on 3 February 1947 at Philadelphia. Although there were discussions to convert her as a guided-missile cruiser, in March 1959 she was officially stricken, and sold on 14 August for scrap.
