John Sidney "Slew" McCain Sr. (9 August 1884 – 6 September 1945) was aUnited States Navyadmiral and the patriarch of theMcCain military family. McCain held several commands during thePacific War ofWorld War II and was a pioneer of aircraft carrier operations. He and his son,John S. McCain Jr., were the first father-and-son pair to achieve four-star admiral rank in the U.S. Navy.
A graduate of theUnited States Naval Academy atAnnapolis, Maryland, class of 1906, McCain's early career was onbattleships andcruisers. DuringWorld War I, he served on convoy duty in theAtlantic. From 1918 to 1935, he alternated between duty ashore with theBureau of Navigation, where he developed officer personnel policies, and at sea, where he commanded thecargo shipUSS Sirius andammunition shipUSS Nitro. He attended theNaval War College inNewport, Rhode Island, in 1928 and 1929. In 1935, he qualified as anaval aviator and commanded theaircraft carrierUSS Ranger from 1937 to 1939.
During World War II, McCain commanded land-based air operations in support of theGuadalcanal campaign. He served as Chief of theBureau of Aeronautics and DeputyChief of Naval Operations for Air. In 1944–1945, he ledTask Force 38 in operations off thePhilippines andOkinawa and air strikes againstFormosa and theJapanese home islands that caused the destruction of Japanese naval and air forces in the closing period of the war. McCain died four days after attending theformal Japanese surrender ceremony on 2 September 1945.
John Sidney "Slew" McCain was born inCarroll County, Mississippi, on 9 August 1884, the third child and second son and namesake ofplantation owner John Sidney McCain and his wife Elizabeth-Ann Young. He had an older brother,William Alexander, an older sister, Katherine Louise, and three younger siblings: Mary James, Harry Hart and Joseph Pinckney.[1][2][3]
McCain attended theUniversity of Mississippi for the 1901–1902 academic year, where he joined thePhi Delta Theta fraternity, and then decided to attend theUnited States Military Academy atWest Point, New York, where his brother William Alexander was enrolled. To practice for its entrance exams, he decided to take the ones for theUnited States Naval Academy atAnnapolis, Maryland; when he passed and earned an appointment from SenatorAnselm J. McLaurin, he decided to attend there instead.[4][5][6]
On 25 September 1902, McCain entered the Naval Academy. He acquired the nickname "Slew". Each summer,midshipmen went on a training cruise to familiarize them with shipboard life. The 1903 cruise was on theUSSChesapeake, abarque skippered byCommanderWilliam F. Halsey Sr., whose sonWilliam F. Halsey Jr., a midshipman two years ahead of McCain, was also aboard. McCain then went to New York forIndependence Day celebrations on thebattleshipUSS Indiana and returned to Annapolis on thesloop-of-warUSS Hartford. The 1904 cruise was also on theHartford, with a return trip on the battleshipUSS Massachusetts, and the 1905 cruise on themonitorsUSS Florida andTerror. McCain failed his annual physical in 1905 on account of defective hearing, but the condition was waived due to the great need for officers.[4][7]
McCain's academic performance was lackluster: when he graduated on 12 February 1906, he ranked 79th out of 116 in his class, and the yearbook labeled him "The skeleton in the family closet of 1906."[8][9] His classmates includedWilliam L. Calhoun,Aubrey W. Fitch,Frank J. Fletcher,Robert L. Ghormley,Isaac C. Kidd,Leigh Noyes,John H. Towers andRussell Willson.[8]
Midshipmen were not immediately commissioned, but had to first serve a year or two at sea. McCain's first assignment, in April 1906, was the battleshipUSS Ohio, theflagship of theAsiatic Fleet, based atManila Bay. After five months he was transferred to theprotected cruiserUSS Baltimore. Then, in January 1907, he became the executive officer of thepatrol boatUSS Panay, under the command ofEnsignChester W. Nimitz. In July, he became the engineering officer on thedestroyerUSS Chauncey. He was promoted to ensign on 18 March 1908.[10] On 27 November 1908, he joined the battleshipUSS Connecticut for the home stretch of theGreat White Fleet's world cruise from 1907 to 1909. TheConnecticut sailed through theSuez Canal and participated in disaster relief efforts for the1908 Messina earthquake in Sicily before reachingHampton Roads on 22 February 1909. He was then ordered to report to thearmored cruiserUSS Pennsylvania on the West Coast.[11][12]

McCain married Katherine Davey Vaulx, who was eight years his senior, inColorado Springs, Colorado, on 9 August 1909, in a ceremony performed by Vaulx's clergyman father, James Junius Vaulx. The couple had three children:John Sidney McCain Jr., James Gordon McCain, and Catherine Vaulx McCain.[13] In December 1909, McCain joined the crew of the armored cruiserUSS Washington as its engineering officer. He appeared before the examination board for promotion to the rank oflieutenant (junior grade) on 2 February 1911 and was questioned about his knowledge of seamanship, navigation, gunnery, and engineering. He was promoted on 10 March, with seniority backdated to 13 February 1911.[12][13]
Duty afloat alternated with duty ashore, so McCain's next posting was to theCharleston Navy Yard, where he was in charge of themachinist's mates school. While there, he was promoted tolieutenant on 5 August 1912, backdated to 1 July, and he temporarily commanded thetorpedo boatUSS Stockton during anaval review in New York from 13 to 15 October 1912.[14][15] In April 1914, he became the executive officer and engineering officer of the armored cruiserUSS Colorado, the flagship for thePacific Fleet. During 1914 and 1915, it patroled the Pacific coast of Mexico during theMexican Revolution. On 11 September 1915, he joined the armored cruiserUSS San Diego as its engineering officer. The ship was placed in reserve in February 1917 but was restored to active service after theAmerican entry into World War I in April. He assumed the acting rank oflieutenant commander on 31 August. This became substantive on 16 January 1918, with seniority backdated to 22 September 1917.[11][16][15]
McCain and theSan Diego served onconvoy duty in theAtlantic Ocean,[11] escorting shipping through the first dangerous leg of their passages to Europe. Based out ofTompkinsville, New York, andHalifax, Nova Scotia,San Diego operated in the weather-torn,submarine-infestedNorth Atlantic. McCain leftSan Diego on 26 May 1918, two months before she was sunk on 19 July by a mine laid by aU-boat, for a new assignment in theBureau of Navigation in Washington, D.C., dealing with the assignment of naval personnel, with the rank of commander from 28 May.[11][16][17]
The Bureau of Navigation handled the assignment, classification and promotion of naval personnel. McCain had to deal with both the wartime expansion of the Navy to 31,194 officers and 495,662 men in 1918, and its post-war demobilization that reduced the Navy to 10,109 officers and 108,950 enlisted personnel in 1920. The Bureau of Navigation sought to retain personnel with valuable skills in the regular service where possible. He served on a board that drafted regulations and legislation for such transfers, and published an article in theUS Naval InstituteProceedings on the wartime "hump" of officers and the system of promotion based on seniority.[18][19] In addition to professional articles in theProceedings, during the inter-war years, McCain was a would-be author who wrote fiction that was never published, including some adventure stories under the name Casper Clubfoot. In one story,The Rout of the Red Mayor, the heroes of the story were theKu Klux Klan.[20][21]

McCain joined the newly-commissioned battleshipUSS Maryland as itsnavigator while it was still fitting out atNewport News Shipbuilding in June 1921. He returned to the Bureau of Navigation in April 1923, working in the office of officer personnel, whose director was CaptainWilliam D. Leahy. McCain participated in another board, drafting legislation of an Equalization Bill that sought to provide officers in specialist staff corps with the same promotion opportunities as line officers.[22][23] The bill was eventually signed into law on 10 June 1926. He also convinced theGeneral Board of the merits of raising the number of years of service for captains before mandatory retirement by a year.[24][25]
On 6 October 1925, McCain was called before a board of inquiry headed by businessmanDwight Morrow into the crash of theairshipUSS Shenandoah. McCain was asked whether aviators should be a separate corps. McCain supported the position of the Bureau of Navigation andBureau of Aeronautics that aviators should remain line officers, and therefore eligible to command ships, but he acknowledged that they had to forgo flight pay during service at sea in non-aviation positions.[24] McCain returned to sea duty in April 1926 to assume command of thecargo shipUSS Sirius. In August he became the executive officer of the battleshipUSS New Mexico, which was commanded by Leahy.[26] McCain submitted a request for flight training in January 1928, but although he passed the physical examination, he was rejected because he exceeded the Bureau of Navigation's age limits for aviator training.[27]
In February 1928, McCain entered theNaval War College inNewport, Rhode Island. His 47 classmates included future admiralsH. Kent Hewitt,Alan G. Kirk andJesse B. Oldendorf. Students studied the works ofAlfred Thayer Mahan,Julian Corbett andHerbert Richmond, with an emphasis on major naval actions like theBattle of Trafalgar,Battle of Tsushima and theBattle of Jutland. McCain wrote theses on the "Causes of the Spanish American War, and the Naval and Combined Operations in the Atlantic, Including the Transfer of the Oregon" and "Foreign Policies of the United States".[26][28][29] On graduation in June 1929, he returned to the Bureau of Navigation, before assuming command of theammunition shipUSS Nitro on 9 June 1931. He was promoted to the temporary rank of captain on 25 September. This became substantive in June 1932, and with seniority backdated to 30 June 1931.[26][30] He leftNitro on 1 April 1933 and returned to the Bureau of Navigation for his third and final tour of duty there. This time he worked on legislation to provide sailors for new ships authorized under the 1934Vinson-Trammell Act.[26]
The Vinson-Trammell Act opened up another opportunity for flight training. Onlynaval aviators andobservers could commandaircraft carriers, aviation shore establishments or air units, but the expansion of the fleet authorized by the act created a shortage of aviators qualified for senior command positions. Leahy was now Chief of the Bureau of Navigation, and he waived the age requirement in McCain's case. McCain's request also received the endorsement of the Chief of the Bureau of Aeronautics, Rear AdmiralErnest J. King, who had completed flight training in 1927. McCain passed the physical; he now required a full set ofdentures but otherwise was considered fully fit and teeth were not a requirement.[27]

On 20 June 1935, McCain reported toNaval Air Station Pensacola for flight training. Training was conducted on the oldConsolidated NY-1 and the newStearman NS-1 biplanes. The training consisted of 465 hours of classroom instruction inaerial navigation,aerodynamics,aerology,aircraft engines,aerial gunnery and communications, and 282.75 hours of flight time that included some night flying.[31][32]
On 18 April 1936, McCain was detached from flight training and went toNaval Air Station North Island in San Diego, where he reported to the aircraft carrierUSS Lexington, which was commanded by Annapolis classmate Captain Aubrey Fitch. Over the following weeks McCain was an observer of war games that simulated an attack on thePanama Canal. At the conclusion, he returned to San Diego on the aircraft carrierUSS Ranger, and then resumed his aviation training at Pensacola.[31][32]
McCain took hisfirst solo flight on 26 July and, on 24 August, at the age of 52, was awarded hiswings and became Naval Aviator No. 4280. He was the second-oldest aviator to earn his wings at Pensacola, after William F. Halsey Jr., who had graduated the year before. His flight training continued until 10 September, by which time he had completed 325 flights totaling nearly 289 hours.[31][32]
McCain hoped for command of an aircraft carrier, but his first aviation posting was toCoco Solo in thePanama Canal Zone. Exercises were conducted under King's watchful eye.[33][34] On 7 April 1937, McCain received orders to assume command of theRanger. He joined the ship in San Francisco on 1 June, and four days later hoisted his flag, relieving CaptainPatrick N. L. Bellinger. Bellinger's executive officer, CommanderAlfred E. Montgomery, stayed on as his executive officer. The embarkedair group consisted of foursquadrons: VF-4, equipped withGrumman F3F fighters;VB-4, withGreat Lakes BG dive bombers; and VS-41 and VS-42, withVought SBU Corsair scout-bombers.[35][36]
In September, theRanger made a goodwill tour to Peru, where McCain was awarded theOrder of the Sun of Peru and the Peruvian Aviation Cross. After an overhaul at thePuget Sound Naval Shipyard from 27 October 1937 to 28 January 1938, theRanger participated inFleet Problem XIX in April and May 1938, which simulated an attack on Hawaii, and Fleet Problem XX in the Caribbean in February 1939, again overseen by King, who flew his flag on theRanger in the final stages of the exercise.[35][36] Based on his experience in command, McCain became an advocate of thearmoured flight deck, which no American carrier possessed at that time.[37][38]
On 1 July 1939, McCain assumed command of Naval Air Station North Island, the only one of its kind on the West Coast untilNaval Air Station Alameda became operational on 1 November 1940. McCain helped Alameda become established, providing assistance in the form of personnel, equipment and expertise.[39][40] He became eligible for promotion to rear admiral in 1939, but was passed over. He felt that his work on legislation for the Bureau of Navigation had not received the recognition that it deserved, and took steps to correct the record. He enlisted the support of King and retired Rear AdmiralRichard H. Leigh. His promotion was approved by PresidentFranklin D. Roosevelt on 23 January 1941.[41][42]
Upon his promotion, McCain assumed command of Aircraft, Scouting Force. In this role he was responsible for the land-based aircraft, and was concurrently Commander, Patrol Wings,United States Fleet. He was impressed with the capabilities of theConsolidated PBY Catalina, but was aware of its limitations. While he advocated an offensive role for the aircraft, he knew that they were too vulnerable to attack shipping in daylight. He therefore prodded theBureau of Ordnance to modify theMark 13 torpedo so that it could be released from an altitude of 200 to 300 feet (61 to 91 m), thereby reducing the risk of aircraft crashing into the sea at night.[43][44] Even after modification, the torpedoes were plagued with reliability problems that were not resolved until 1944. By then, a series of changes had been made that allowed the torpedoes to be dropped from 800 feet (240 m) at a speed of 260 knots (480 km/h; 300 mph), which greatly enhanced the chance of the torpedo bomber surviving the attack.[45]
The Japaneseattack on Pearl Harbor on 7 December 1941 brought the United States intoWorld War II. Of the 54 patrol planes based there, only one was undamaged. McCain deployed his patrol planes to warn against attacks by Japanese submarines or aircraft carriers or an invasion of Hawaii or California. His command was redesignated Patrol Wings, Pacific Fleet, on 10 April, and was transferred from the control of theWestern Sea Frontier to AdmiralChester W. Nimitz's Pacific Fleet.[46]
On 1 May 1942, McCain was appointed Commander, Aircraft,South Pacific Area. As such, he commanded land-basedAllied air operations supporting theGuadalcanal campaign in theSolomon Islands.[47] He hoisted his flag on theseaplane tenderUSS Tangier inNoumea on 20 May; it was replaced by theUSS Curtiss in June. His immediate task was developing air bases to support his patrol planes and heavy bombers.[48] Aircraft carriers were available for thelandings on Tulagi and Guadalcanal on 7 August, but only for the first two days. McCain's aircraft then had to provide air support until theairfield on Guadalcanal could be made operational. However, his fighters based onEfate did not have the range to reach Guadalcanal withoutdrop tanks, which were in short supply.[49] He gave a high priority to completion of a new airfield onEspiritu Santo.[50] A fighter squadron arrived on 28 July and firstBoeing B-17 Flying Fortress landed on the newly-completed airfield the next day.[51]

In theBattle of Savo Island on 8 August, a Japanese cruiser force attacked the Allied one screening the landing, sinking one Australian and three American cruisers, while suffering only light damage in return. It was the Navy's second greatest defeat, exceeded only by Pearl Harbor. AdmiralArthur J. Hepburn, a former commander in chief, United States Fleet, and the chairman of theGeneral Board, conducted an investigation into the circumstances.[52] In his report, Hepburn noted that there was a twilight zone between "culpable inefficiency on the one hand and more or less excusable error of judgment on the other".[53] He ascribed the defeat to the Allied force being surprised. While not specifically blaming McCain, Hepburn attributed this to the failure of air patrols to detect the approach of the Japanese force. In his endorsement of Hepburn's report, Nimitz concurred that one of the causes of the disaster was the "failure of either carrier or land-based air to conduct effective search and lack of coordination of searches."[53]
In the aftermath of the disaster, the commander of the South Pacific Area, Vice AdmiralRobert L. Ghormley, ordered McCain to withdraw the seaplane tendersUSS Mackinac andMcFarland fromMalaita andNdeni respectively, which he regarded as now too vulnerable. This disrupted the search plan and forced McCain to deploy his PBY patrol planes from Espiritu Santo and a new base McCain established atVanikoro in theSanta Cruz Islands. The airfield on Guadalcanal, which the1st Marine Division's commander, Major GeneralAlexander A. Vandegrift, named Henderson Field after MajorLofton R. Henderson, a marine aviator who had been killed in theBattle of Midway, was considered operational on 12 August. The following day, theescort carrierUSS Long Island arrived atSuva with 18F4F Wildcat fighters and 12SBD Dauntless dive bombers. The ship's captain asserted that the marine fighter pilots were not sufficiently trained to take off from the carrier, so McCain swapped eight of them with more experienced aviators from Efate. They arrived on Guadalcanal on 20 August, and became the nucleus of what became theCactus Air Force.[54][55]
McCain seized every opportunity to reinforce the Cactus Air Force. He sent ArmyBell P-400 Airacobra fighters, and retained 11 SBDs from the aircraft carrierUSS Enterprise that landed on Henderson Field after theEnterprise was damaged in theBattle of the Eastern Solomons.[56] But aircraft were lost at alarming rates.[57] Nimitz was not satisfied with McCain's performance and resolved to relieve him of his command.[58] Meanwhile, in Washington, DC, Admiral Ernest J. King, who was now the Commander in Chief US Fleet, had clashed with the chief of the Bureau of Aeronautics, Rear AdmiralJohn H. Towers, over King's plans to reorganise the Navy Department, which involved asserting more control over the bureaus. King and Nimitz met in San Francisco on 6 and 7 September 1942, and agreed on new command arrangements: Towers would be promoted to vice admiral and sent to Nimitz asCommander Naval Air Force, Pacific Fleet; the incumbent, Rear AdmiralAubrey W. Fitch, would replace McCain as Commander, Aircraft, South Pacific Area; and McCain would succeed Towers as chief of the Bureau of Aeronautics.[59][60] McCain was awarded theNavy Distinguished Service Medal for his part in "the occupation of the Guadalcanal-Tulagi area by our forces and the destruction and serious damaging of numerous aircraft and vessels of the enemy".[41]

Fitch relieved McCain on 21 September.[61]Time magazine opined that "it was a promotion for Admiral Towers but a demotion for the Navy's air arm ... New BuAer Chief Rear Admiral John Sidney McCain, 58, is a good officer. But like many other so-called air admirals, he got an airman's rating late, is not an airman by profession, but a battleship admiral with pay-and-a-half and a flying suit."[62] His son Gordon wrote a rebuttal letter toTime, pointing out that while McCain "has had no armchair or laboratory contact with 'air developments' he has had considerable peacetime and some combat flying experience."[63] In a letter to Nimitz, theSecretary of the Navy,Frank Knox, also defended the appointment. "Towers," he wrote, "while able, is not a good administrator or coordinator. I think McCain is both."[64]
McCain inherited from Towers an organization still in the throes of a massive wartime expansion. There were 1,098 officers on duty in the Bureau of Aeronautics in December 1942, up from 58 three years before. His first priority was to meet the needs for aircraft in the South Pacific, where they were being shot down and written off faster than they could be delivered. The Navy had 2,172 aircraft in June 1940; by the end of 1942 it had 7,058. TheWar Production Board had set a target of 107,000 aircraft to be delivered in 1943, of which the Navy was to receive 24,116. The Bureau of Aeronautics estimated that only 17,000 would be delivered, but that was still twice as many as had been delivered in 1942.[65][66]

On 13 December 1942, Knox issued a directive that authorized the technical bureaus "to negotiate, prepare, and execute their own contracts."[67] Henceforth, the Bureau of Aeronautics procured major aeronautical items like air frames and engines.[67] To administer procurement, McCain created Contracts, Contracts Administration, and Records and Distribution sections within the Procurement Branch of Bureau of Aeronautics's Material Division.[68] Training the required personnel was another challenge. On 8 April 1943, the Bureau of Aeronautics estimated that 35,495 pilots would be needed in 1943 but only 30,500 would be available.[69]
An important aspect of the Bureau of Aeronautics's work was the development of requirements for new aircraft in response to lessons learned in combat.[69] Like many personnel who had served on Guadalcanal, McCain's sleep had been interrupted byWashing Machine Charlie, Japanese aircraft that had conducted nocturnal operations over the island. In June 1943, Marine aviators returning to the UK reported that the British believed that a twin-enginenight fighter was required. The result was the development of theGrumman F7F Tigercat. As an interim measure, the Bureau of Aeronautics fittedVought F4U Corsair andGrumman F6F Hellcat fighters as night fighters. McCain also believed that these fighters could serve as bombers and had them modified to carry bombs and rockets. He also took steps to develop jet aircraft, starting with theRyan FR Fireball.[70][71]
In May 1943, King made another attempt to reorganize the Navy Department to bring more of it under his own control. He proposed to do so by creating four Deputy Chiefs of Naval Operations. This did not meet with approval from Roosevelt, but the creation of a Deputy Chief of Naval Operations for Air was authorized. McCain was chosen for the position, with the rank of vice admiral from 28 July. The Bureau of Aeronautics's Planning, Personnel, Training, and Flight Divisions were transferred to the new office. Rear AdmiralDeWitt Clinton Ramsey succeeded McCain as Chief of the Bureau of Aeronautics.[72][73]

By March 1944, McCain was aware that he was in line to command an aircraft carrier task force. He approached CommanderJohn S. Thach and asked him to become his operations officer. Thach accepted, and McCain arranged for both to be attached to theFifth Fleet on temporary duty. From 26 May to 21 June, McCain was on board the cruiserUSS Indianapolis, the flagship of the fleet commander, AdmiralRaymond A. Spruance, whence he was able to observe theinvasion of Saipan and theBattle of the Philippine Sea. At this stage of the war, the fleet was divided intotask forces, which in turn were divided into two to five task groups. Each aircraft carrier task group consisted of four or five aircraft carriers, along with their destroyer, cruiser and battleship escorts.[74][75]
Next, McCain transferred to the aircraft carrierUSS Lexington, where he understudied Vice AdmiralMarc Mitscher, the commander of the First Fast Carrier Task Force Pacific, also known asTask Force 58, while Thach worked with Mitscher's operations officer, CaptainArleigh Burke. Finally, from 24 to 26 June, McCain was an observer with Rear AdmiralJohn W. Reeves Jr.'s Task Group 58.3. After Task Force 58 returned toEniwetok, McCain flew to the United States on 3 July and was back in Washington, DC, three days later. He handed over the position of the Deputy Chief of Naval Operations for Air to Fitch on 1 August.[74][75]
Instead of McCain taking charge of the First Fast Carrier Task Force Pacific as he expected, Mitscher stayed on, and McCain was nominally given command of the Second Fast Carrier Task Force Pacific.[76][77] Under a new organization implemented by Nimitz, there would be two fleets. They would consist of the same ships, but there would be two fleet commanders, Halsey and Spruance. When Halsey was in charge, the fleet would be called theThird Fleet; when Spruance was in charge, it would be called the Fifth Fleet. While one commanded at sea, the other would plan the next operation.[78]
McCain would have liked to have taken Mitscher's experienced staff, but under this dual-command arrangement he was compelled to select a new one. For his chief of staff, he chose Rear AdmiralWilder D. Baker. As a learning exercise, McCain took over Task Group 58.1 from Rear AdmiralJoseph J. Clark. This was awkward, as McCain was senior to Mitscher. Task Group 58.1 comprised the aircraft carriersUSS Wasp andHornet, the light carriersUSS Cowpens andBelleau Wood, the cruisersUSS Boston,Canberra andWichita, and eleven destroyers. McCain hoisted his flag on theWasp on 18 August. Clark remained on board to advise McCain until the end of September. When AdmiralWilliam F. Halsey Jr. assumed command of the fleet from Spruance on 26 August, the fleet became the Third Fleet and Task Group 58.1 became Task Group 38.1.[76][77]
Task Group 38.1 sortied from Eniwetok on 29 August 1944. McCain conducted a series of air strikes on targets in theCaroline Islands and Philippines in support of the landings onPeleliu andMorotai. In his report on the operations, McCain recommended that the number of fighters aboard hisEssex-class aircraft carriers be increased, as in the future they would be often operating in range of large numbers of land-based aircraft. King authorized an increase in their fighter strength from 36 to 54, with a corresponding reduction in the number ofCurtiss SB2C Helldiver dive bombers being carried.[79][80]
Afterrevictualing atManus Island, Task Group 38.1 sortied again on 2 October, this time in support of thelanding on Leyte. McCain conducted a series of strikes against airfields on Formosa, which precipitated theFormosa Air Battle. On the night of 12 October, Task Group 38.1 was attacked by fourteen Japanese aircraft, all of which were shot down by anti-aircraft guns and night fighters. At 18:23 on the following evening, there was another attack by ten torpedo bombers that were not picked up on radar.Canberra was torpedoed andWasp suffered minor damage when one of the bombers crashed off the starboard bow. McCain hadWichita takeCanberra in tow, and had his carriers provide protective air cover. The Japanese attacked again at dusk the next evening, and torpedoed theUSS Houston, which had been sent to augment McCain's screen. On 15 October, Task Group 38.1 came under relentless attack by an estimated 80 aircraft, of which 52 were claimed to have been shot down. Two American fighters were lost, but the cruisers were saved.[81][82]
McCain was awarded theNavy Cross. His citation read:
The President of the United States takes pleasure in presenting the Navy Cross to John Sidney McCain, Vice Admiral, U.S. Navy, for extraordinary heroism and distinguished service in the line of his profession as Commander, Task Group 38.1, after the torpedoing of the USSCanberra and USSHouston by Japanese aerial forces, ninety miles off the Island of Formosa, during the period 13 to 15 October 1944. Vice Admiral McCain interposed his task group to cover the withdrawal of the USSCanberra and USSHouston and by his skillful and courageous handling of his forces broke up repeated heavy enemy air attacks. His actions contributed in great measure to the ultimate successful salvaging of the two damaged cruisers. Vice Admiral McCain's inspiring leadership and the valiant devotion to duty of his command contributed in large measure to the outstanding success of these vital missions and reflect great credit upon the United States Naval Service.[83]

After replacing the damaged ships, Task Group 38.1 consisted of the carriers USSWasp,Hornet andMonterey; cruisersUSS Chester,Pensacola,Salt Lake City,Oakland andSan Diego; and twelve destroyers. On 22 October they were augmented by the return ofCowpens and the addition of theUSS Hancock and its escorts. That night, Halsey directed McCain to replenish atUlithi, so Task Group 38.1 headed east.[84][85] At 08:46 on 24 October, with indications of an impending naval battle, Halsey ordered McCain to reverse course,refuel at sea, and conduct air searches. McCain reached the rendezvous point and refueling commenced at 07:24 on 25 October. Monitoring the radio circuits, McCain realised that Vice AdmiralThomas C. Kinkaids' escort carriers wereunder attack off Samar and, on his own initiative, ordered Task Group 38.1 to complete refueling and head towards Samar at 25 knots (46 km/h; 29 mph).[86][87]
McCain recovered hiscombat air patrol and increased speed to 30 knots (56 km/h; 35 mph). Although the airfield atTacloban on Leyte reported that it was usable in an emergency, McCain ordered hisGrumman TBF Avenger torpedo planes loaded with bombs instead of torpedoes to extend their range. To save time, since the wind was from the east, he adopted the unusual maneuver of having the carriers increase speed to 33 knots (61 km/h; 38 mph), turn into the wind to launch aircraft, then turn about and catch up with the escorts. His first strike, consisting of 48 Hellcats, 33 Helldivers and 19 Avengers departed at 11:02, followed by a second of 35 Hellcats, 20 Helldivers and 21 Avengers. Six aircraft were lost; several had to land at Tacloban or on the escort carriers. A single bomb hit was made on theJapanese cruiser Tone. While King, Nimitz and subsequent historians had considerable criticisms of Halsey's handling of the Third Fleet in the battle, McCain was commended for his handling of Task Group 38.1, especially for actions taken on his own initiative.[86][88]
On 30 October 1944, McCain assumed command of Task Force 38.[89] McCain conducted air strikes against targets in the central Philippines andLuzon while covering theBattle of Leyte. Being tied to a single location made the Third Fleet vulnerable, and between October and December, three aircraft carriers were forced bykamikaze attacks to return to shipyards for repairs. McCain instituted new tactics to deal with them.[90] McCain continued to press for more fighters on his carriers, recommending on 20 November that the Helldivers be replaced with fighters. On 23 December, King announced that for the next cycle of operations, theEssex-class carriers would have 72 fighters, 15 dive bombers and 15 torpedo planes.[91]

While conducting operations off the Philippines on 17 December, McCain participated in Halsey's decision to keep the combined naval task force on station rather than avoid a major storm,Typhoon Cobra (later known also as "Halsey's Typhoon"), which was approaching the area. The storm sank three destroyers and inflicted heavy damage on many other ships. Some 800 men were lost, in addition to 186 aircraft. A Navy court of inquiry found that Halsey committed "errors of judgment" in sailing into the typhoon, but did not recommend sanction.[92]
On 8 and 9 January, McCain conducted air strikes against targets in Formosa and theRyukyus. Task Force 38 then sailed through theLuzon Strait andraided the South China Sea.[93] A series of air strikes against targets inFrench Indochina saw Task Force 38 sink 15 warships and 29 merchant ships, twelve of which wereoil tankers.[94] As part of the routine change of leadership, Halsey and McCain were relieved by Spruance and Mitscher respectively on 26 January 1945, and Task Force 38 became Task Force 58 again.[95]
Between 30 October 1944 and 26 January 1945, Task Force 38 had destroyed or damaged 101 Japanese warships and 298 merchant ships; its aircraft had shot down 357 Japanese aircraft over targets and 107 in the air over the task force; its anti-aircraft guns had accounted for 21 more, and 1,172 were destroyed on the ground. On the other side of the ledger, Task Force 38 had lost 203 aircraft, 155 pilots and 96 aircrew during operations, and 180 aircraft, 43 pilots and 9 aircrew in accidents.[95] McCain was awarded aGold Star to his Distinguished Service Medal on 23 March 1945, for his "brilliant tactical control" of the fast carrier forces during operations in the Philippines and South China Sea from September 1944 to January 1945.[96][97]

After a period of leave in the United States, McCain reported back to Pearl Harbor on 1 April 1945. On 17 May, he hoisted his flag on the aircraft carrierUSS Shangri-La at Ulithi. He relieved Mitscher on 28 May, and Task Force 58 became Task Force 38 once more.[98]
On 4 June, Task Force 38 encounteredTyphoon Connie (also known as Typoon Viper). McCain recommended to Halsey that Task Force 38 leave the area. Halsey agreed, but postponed a decision to depart until he had more information. McCain wanted to head east, which would have put Task Force 38 out of harm's way, but at 20:00 Halsey ordered Task Force 38 to set course to 300 degrees. McCain thought this would be headed into the typhoon, but complied with the order.[99][100]
On receipt of more information, McCain changed course to 000 degrees at 03:00. At 04:20 on 5 June, Clark, in command of Task Group 38.1, which was getting the worst of the storm, informed McCain that he could steer clear of it by altering course to 120 degrees. McCain checked with Halsey, who told him to maintain course. McCain was sailing with Task Group 38.4, which was getting clear on the current course of 000 degrees, and saw no reason to alter it, but gave Clark permission to use his own judgment at 04:40.[99][100]
No ships sank in this storm, but six men died and 33 ships were damaged,[101] including the cruiserUSS Pittsburgh, which lost its bow.[102] Aircraft lost included 33 swept overboard, 36 jettisoned and 7 damaged beyond repair.[103] The court of inquiry assigned primary blame to Halsey for the change of course from 110 to 300 degrees, but assigned secondary blame to McCain for the twenty-minute delay in granting Clark permission to change course. The court recommended that consideration be given to relieving Halsey and McCain of their commands.[99][104][105]
The new Secretary of the Navy,James Forrestal, was in favor of retiring Halsey. King agreed, but felt that since Halsey was a popular hero, his relief would make the Navy look bad. McCain was more vulnerable, and Nimitz decided to replace him.[99][104][105] On 15 July, McCain was informed that he would be handing over command of Task Force 38 to Towers on 1 September 1945 and become the deputy head of theVeterans Administration under GeneralOmar Bradley.[106]
McCain remained in command of Task Force 38 through July, as Task Force 38 conducted raids on the home islands of Japan. McCain had doubts about the wisdom of conductingattacks on warships and shipping inKure and theSeto Inland Sea, believing that attacks on airfields and aircraft factories were a better use of his resources, but he complied with Nimitz's orders.[107]

By war's end in August 1945, the stress of combat operations, lifelong anxiety, and probable heart disease had taken its toll.[108] McCain requested home leave to recuperate, but Halsey insisted that he be present at theJapanese surrender ceremony inTokyo Bay on 2 September.[104]
Departing immediately after the ceremony, McCain arrived home inCoronado, California, on 5 September. In the middle of a welcome-home party the following afternoon, he told his wife that he did not feel well. At 17:10, he died of aheart attack. He was 61 years old.[109][104][110] His death was front-page news across the United States.[110][111] He was buried atArlington National Cemetery.[112] His honorary pall bearers were GeneralAlexander Vandegrift, Vice Admirals Russell Willson, Leigh Noyes andFerdinand Reichmuth, and Rear Admirals George S. Bryan andMatthias Gardner.[113]
Short in stature and of rather thin frame, McCain was gruff and profane; he liked to drink and gamble. He showed courage and was regarded as a natural, inspirational leader. In the words of one biographical profile, McCain "preferred contentious conflict to cozy compromise."[114]
In 1949, McCain was posthumously promoted to admiral by a resolution ofCongress. This followed a recommendation ofSecretary of the NavyFrancis P. Matthews, who said that McCain's combat commendations would have earned him the promotion had he not died so soon after the war.[115] The date of rank was 6 September 1945, the day he died.[113] When his son later achieved this rank, they became the first father-and-son pair to do so.[116]

There were other posthumous honors. In December 1945,King George VI made McCain an honoraryKnight Commander of the Order of the British Empire. Aninvestiture ceremony was held on board the cruiserHMS Sheffield (anchored inLong Beach harbor) in July 1948.[118] In April 1946, McCain was awarded a second gold star to his Distinguished Service Medal for his service in command of Task Force 38 from 28 May to 1 September 1945. His citation read:
Combining brilliant tactics with effective measures to counter the enemy's fanatical aerial onslaughts, he hurled the might of his aircraft against the remnants of the much-vaunted Japanese Navy to destroy or cripple the every remaining major hostile ship by 28 July. An inspiring and fearless leader, Vice Admiral McCain maintained a high standard of fighting efficiency in his gallant force while pressing home devastating attacks which shattered the enemy's last vital defensive hope and rendered him unable to protect his shipping even in waters off the mainland of Japan.[118]
McCain Field, the operations center atNaval Air Station Meridian,Mississippi, was named in his honor.[114] The observatory building at the University of Mississippi was renamed McCain Hall on 7 October 1947. It housed the university'sNaval Reserve Officers Training Corps (ROTC) unit until 1989. It has since been renamedBarnard Observatory, but the new Naval ROTC spaces, in another building, were named the McCain Quarterdeck in April 2003.[119]
The guided-missile destroyerUSS John S. McCain (DL-3) (in service from 1953 to 1978) was named after him,[120][121] and the destroyerUSS John S. McCain (DDG-56) (commissioned in 1994 and still in service as of 2024[update]) was named for him, his son, Admiral John S. McCain Jr., and, as of a rededication ceremony on 11 July 2018, his grandsonJohn S. McCain III.[116][122][123]
