Task Force 17 (TF17) was an aircraft carrier task force of the United States Navy during the Pacific Campaign of World War II. TF17 participated in several major carrier battles in the first year of the war.

TF17 was initially centered around USS Yorktown. With Yorktown, TF17 engaged Imperial Japanese Navy forces in actions at the Marshalls-Gilberts raids, Invasion of Lae-Salamaua, Battle of the Coral Sea, and the Battle of Midway. Yorktown was sunk at Midway.

Reformed around USS Hornet and commanded by RADM George Murray, TF17 supported Allied forces during the Guadalcanal campaign. At the Battle of the Santa Cruz Islands, Hornet was sunk. After the battle the task force ceased to exist, the remaining ships (the cruiser and destroyer escorts) were then dispersed to other duties.

In late April 1942, Admiral Chester Nimitz ordered for Rear Admiral Aubrey Fitch, commander of Task Force 11 (TF11) centered on USS Lexington, to travel to the Coral Sea to join Fletcher's Task Force 17. An additional cruise force, Task Force 44, was deployed from the south.[1]

The rendezvous took place on 1 May, but Fitch advised Fletcher that he "did not expect to complete fueling till noon on 4 May." Fletcher moved TF17 further to the northwest. RADM Fitch was advised by RADM Fletcher of a second rendezvous, scheduled for 4 May and would have the Australian cruisers HMAS Australia (D84) and HMAS Hobart (D63) join with TF44.[1]

As the American Task Forces were refueling, attempting to move to favorable positions in order to intercept incoming Japanese forces, Japan launched the Invasion of Tulagi, part of Operation Mo. Upon receiving notice regarding the Japanese invasion of Tulagi, RADM Fletcher ordered TF17 to head there, hoping for arrival on the morning of 4 May.[1]

By 06:30, 4 May, Yorktown made the first of three strikes at around 08:15, assaulting Japanese shipping in the harbor. After completing the strikes, Fletcher moved south to rendezvous with Fitch and RADM John Gregory Crace or TF44.[1]

Lexington was lost during the battle while Yorktown was hit by a bomb. The hit reduced Yorktown's speed to 24 knots. By 12:30 TF17, with the remainder of Lexington's aircraft on Yorktown, were forced to return to Pearl Harbor. For the Japanese aircraft carriers, Shokaku had been severely damaged and returned to Truk. The second carrier, Zuikaku, also left, as it was low on aircraft, fuel, and personnel.[2] As a result, Admiral Inouye ordered for the Moresby invasion to be postponed and for the ships to retire.[1]

Fletcher and TF17 returned to Pearl Harbor where Yorktown was serviced in preparation for the Battle of Midway.[1]

Battle of Midway

[edit]
Further information: Battle of Midway

TF17, under the command of Rear Admiral Frank Jack Fletcher, was to depart from Pearl Harbor, and did so on 30 May, to join Task Force 16 (TF16), centered around USS Enterprise (CV-6) and USS Hornet (CV-8), northeast of Midway Island. TF16 and TF17 joined about 350 miles northeast of Midway on 2 June, when Fletcher became officer in tactical command. The three aircraft carriers, supported by cruiser-launched floatplanes, provided 234 aircraft.[3]

Yorktown was lost during the battle; damaged by aircraft (bombs and torpedoes) from Japanese aircraft carrier Hiryū 4 June 1942, torpedoed by Japanese submarine I-168 on 6 June 1942, and capsized and sank on 7 June 1942.[4]

Task Force 17

View on Grokipedia
from Grokipedia
Task Force 17 (TF 17) was an aircraft carrier task force of the United States Navy that operated during the Pacific Campaign of World War II, playing a critical role in early carrier battles against Japanese forces. Initially formed around the aircraft carrier USS Yorktown (CV-5) and commanded by Rear Admiral Frank Jack Fletcher, TF 17 conducted raids and supported Allied operations in the South Pacific from late 1941 onward. In May 1942, TF 17 participated in the Battle of the Coral Sea, where it rendezvoused with Task Force 11 (centered on USS Lexington) to intercept a Japanese invasion force targeting Port Moresby, New Guinea. Under Fletcher's overall command, TF 17's aircraft struck Japanese shipping at Tulagi on 4 May, sinking several vessels including destroyers and gunboats, before engaging in a carrier battle on 7–8 May that damaged the Japanese carrier Shōkaku and sank the light carrier Shōhō, though Lexington was lost and Yorktown sustained damage. This action marked the first battle in history where aircraft carriers engaged each other and denied Japan a key strategic advance in the region. Following rapid repairs to Yorktown at , TF 17 joined Task Force 16 (with USS Enterprise and USS Hornet) for the in early 1942, with Fletcher exercising tactical command over the combined force. TF 17's aircraft contributed to the sinking of three Japanese carriers (Akagi, Kaga, and Sōryū) on 4 , a turning point that crippled Japan's carrier strength, though Yorktown was critically damaged by air attack and later torpedoed by I-168, sinking on 7 with significant loss of life. After Midway, TF 17 was reformed around USS Hornet (CV-8) under Rear Admiral George D. Murray and redeployed to support the Guadalcanal campaign in the Solomon Islands. Operating as the primary U.S. carrier in the South Pacific following the loss of USS Wasp in September 1942, TF 17 conducted strikes against Japanese positions on Guadalcanal and nearby targets. During the Battle of the Santa Cruz Islands on 26 October 1942, TF 17's aircraft inflicted heavy damage on Japanese carriers, but Hornet was struck by multiple bombs and torpedoes from aircraft of Jun'yō, Shōkaku, and Zuikaku, leading to its abandonment and scuttling by U.S. forces after failed salvage attempts. This engagement, while a tactical Japanese victory, further weakened their naval aviation capabilities amid the ongoing Guadalcanal struggle.

Background

Formation

Task Force 17 was established in late December 1941 as part of the U.S. Pacific Fleet's reorganization following the Japanese attack on Pearl Harbor on December 7, 1941. This formation occurred under the direction of the newly appointed , Pacific Fleet (CINCPAC), Admiral , who assumed command on December 31, 1941, amid efforts to rebuild and reposition naval forces for counteroffensives. The was designated TF17 to embody the emerging doctrine, which prioritized concentrated for rapid, mobile strikes against Japanese-held territories in the Central Pacific. Its primary purpose was to conduct offensive operations, including carrier-based air raids, to disrupt Japanese advances and regain initiative in the theater. Administratively, TF17 was organized at , , serving as the initial operational base for coordination and logistics within the Pacific Fleet structure. The USS Yorktown (CV-5), arriving in on December 30, 1941, after a transit from the Atlantic via the , was immediately incorporated as the task force's flagship, highlighting the urgency of post- resource allocation. was appointed commander on January 1, 1942, tasked with integrating recovered ships, aircraft, and personnel into a cohesive unit ready for deployment. This setup emphasized flexibility, with TF17 positioned to support fleet-wide initiatives while drawing on the Navy's ongoing recovery from the initial losses at .

Initial Composition

Task Force 17 was initially built around the USS Yorktown (CV-5) as its , which served as the primary striking force with a capacity for up to 90 . The Yorktown, commissioned in , displaced 19,800 tons and was equipped with eight 5-inch guns for defense, enabling it to project air power across vast Pacific distances during early operations. Supporting the carrier were the heavy cruiser USS Louisville (CA-28) and the light cruiser USS St. Louis (CL-49), which provided anti-aircraft and surface gunfire support while scouting ahead. The Louisville, a 10,000-ton Portland-class vessel armed with nine 8-inch guns in three triple turrets, and the St. Louis, a 9,700-ton Brooklyn-class light cruiser with fifteen 6-inch guns, formed a protective screen against potential surface threats. The destroyer screen consisted of four vessels: USS Hughes (DD-410), USS Sims (DD-409), USS Russell (DD-414), and USS Walke (DD-416), all Sims-class ships designed for anti-submarine warfare, escort duties, and torpedo attacks, with speeds exceeding 35 knots and armament including five 5-inch guns and depth charge racks. The air component, known as Yorktown Air Group, comprised specialized squadrons for combat roles. Fighting Squadron 42 (VF-42) operated 9 F4F-3 fighters, capable of 331 mph and armed with six .50-caliber machine guns for air superiority and patrol duties. Bombing Squadron 5 (VB-5) flew 17 Douglas SBD-3 Dauntless dive bombers, each able to deliver a 1,000-pound bomb with precision from steep dives. Squadron 5 (VS-5) included 17 SBD-3 Dauntless for and , while Squadron 5 (VT-5) had 12 Douglas TBD-1 Devastator bombers, the Navy's standard aircraft at the time, though limited by a top speed of 206 mph and vulnerability to enemy fire. Organizationally, the force was divided into subgroups for operational efficiency, typically including a carrier group, division, and screen, though specific commanders and assignments varied by mission. In total, Task Force 17's initial personnel numbered approximately 4,500 sailors and aviators, encompassing the carrier's crew, air group pilots and maintenance staff, and complements, and command elements. This force represented a balanced, mobile unit optimized for carrier-centric warfare in the early Pacific campaign.

Command Structure

Frank Jack Fletcher

Frank Jack Fletcher was born on April 29, 1885, in Marshalltown, Iowa. He graduated from the United States Naval Academy in 1906 and was commissioned as an ensign in 1908, beginning a career marked by service on battleships such as USS Rhode Island, USS Ohio, and USS Maine. During World War I, Fletcher served as gunnery officer aboard USS Kearsarge and commanded several vessels, including gunboat USS Margaret, destroyer USS Allen, and destroyer USS Benham, earning the Navy Cross for his role in protecting Atlantic convoys from submarine threats. In the interwar period, he commanded destroyers USS Whipple, USS Sacramento, and USS Rainbow; served as chief of staff to the U.S. Asiatic Fleet from 1931 to 1933; and took command of battleship USS New Mexico from 1936 to 1937. Promoted to rear admiral effective November 1, 1939, he assumed command of Cruiser Division Three that year and later Cruiser Division Six by December 1941. In January 1942, following the Japanese attack on Pearl Harbor, Fletcher was appointed commander of the newly formed Task Force 17 (TF 17), with USS Yorktown as his flagship, and Captain Spencer S. Lewis serving as his chief of staff. His leadership emphasized cautious tactics, prioritizing thorough reconnaissance to assess enemy positions and the preservation of carrier assets amid the precarious balance of U.S. naval strength in the early Pacific War. This approach influenced operations such as the early raids on Japanese-held islands, where he managed fuel constraints and scouting missions to avoid unnecessary risks, and the Battle of the Coral Sea, where reliance on search aircraft reports allowed him to position TF 17 effectively while detaching supporting forces to interdict enemy advances without exposing carriers to undue peril. Fletcher commanded TF 17 from its formation through July 1942, overseeing all major operations up to and including the . A notable personal decision during this tenure was his urgent return of the damaged to after the Coral Sea engagement; under Admiral Chester Nimitz's directive, shipyard workers completed essential repairs in just 72 hours—far short of the estimated three months—enabling the carrier to sortie for Midway and restoring critical striking power to the fleet. At Midway, after Yorktown sustained further damage, Fletcher transferred tactical command to , reflecting his commitment to force preservation. Command of TF 17 later passed to in the fall of 1942.

George D. Murray

George Dominic Murray was born on July 6, 1889, in , . He graduated from the in 1910 and qualified as a naval aviator in 1915, becoming the 22nd U.S. Navy officer to earn that designation. Throughout his career, Murray served in both the Atlantic and Pacific fleets, accumulating extensive experience in naval aviation and fleet operations. Prior to his assignment with Task Force 17, he commanded the aircraft carrier from March 1941 to June 1942, leading it through significant early actions including the and the . In August 1942, following Vice Admiral Frank Jack Fletcher's reassignment after the , Rear Admiral was appointed Commander, Task Force 17 (CTF-17). He oversaw the reformation of the task force around the USS Hornet as its flagship, inheriting elements from the post-Midway reorganization and preparing it for operations in the South Pacific. Murray's command emphasized direct carrier support for the ongoing Allied landings on , prioritizing offensive actions to protect the beachhead and disrupt Japanese reinforcements. Murray's tenure as CTF-17 extended from August to October 1942, encompassing command during the and the . A key element of his leadership was coordinating carrier strikes with Task Force 16 under Vice Admiral , enabling combined U.S. naval air power to contest Japanese advances near . Following the loss of USS Hornet at Santa Cruz on October 26, 1942, Task Force 17 was disbanded, marking the end of Murray's command.

Operational History

Marshalls-Gilberts Raids

The Marshalls-Gilberts raids marked Task Force 17's inaugural offensive operation in the Pacific theater, conducted as a diversionary strike to draw Japanese attention away from preparations for the on the Japanese home islands. Departing on 22 January 1942 under the command of Rear Admiral , Task Force 17—centered on the aircraft carrier USS Yorktown (CV-5), accompanied by heavy cruisers USS Astoria and USS Louisville, and destroyers USS Blue, , USS Aulick, and USS Morris—advanced into the central Pacific. Initial intelligence was provided by on Japanese Fourth Fleet movements and shuttle patrols of B-17s and patrol planes observing activities in the region. The operation spanned 1–7 February 1942, with the main strikes launched on 1 February from a position approximately 150 nautical miles southeast of Jaluit Atoll in the Marshall Islands. Fletcher coordinated the attacks to exploit dawn conditions for surprise, directing Yorktown's air group—comprising approximately 31 SBD Dauntless dive bombers from bombing squadrons VB-5 and VS-5, 11 TBD Devastator torpedo bombers from VT-5, supported by 11 F4F Wildcat fighters from fighting squadron VF-5—to divide into three coordinated groups targeting Japanese installations in the Gilbert and Marshall Islands, though strikes were hampered by poor weather reducing visibility. One group of 9 SBDs struck Makin Atoll in the Gilberts, focusing on a seaplane tender and associated four-engine seaplanes; a second formation of 17 SBDs and 11 TBDs hit Jaluit Atoll, targeting auxiliary vessels, administrative buildings, and the airfield; while a third of 5 unescorted SBDs attacked Mili Atoll, aiming at storehouses and a fuel storage tank, though low ceilings prevented observed hits. Fighters provided combat air patrol rather than strike escorts. Strict radio silence and cautious routing avoided Japanese reconnaissance patrols, ensuring the task force remained undetected throughout the approach and execution. The raids inflicted moderate damage on Japanese assets, starting fires at airfields on Makin and Jaluit that destroyed several on the ground and disrupting operations, while hits damaged at least six and auxiliary vessels, including the 3,249-ton Nagata Maru at Makin and the Kanto Maru at Jaluit. Although no major warships were sunk by 17's , the overall operation—coordinated with concurrent strikes by other U.S. forces—contributed to the sinking of one Japanese through surface gunfire elsewhere in the Marshalls. U.S. losses were limited to one from action, with additional planes and crews lost to encountered during recovery operations near Jaluit, totaling six unaccounted for but not attributed to enemy fire. 17 withdrew undetected on 1 February, rendezvousing with supporting elements and returning to by 7 February without sustaining any damage. These hit-and-run strikes, the first U.S. Navy offensive against Japanese-held territory following Pearl Harbor, provided a much-needed morale boost to American forces and the public by demonstrating the viability of carrier-based power projection and validating Fletcher's cautious yet effective leadership in early carrier warfare.

Lae-Salamaua Operations

Task Force 17, centered on the aircraft carrier USS Yorktown, participated in the Lae-Salamaua operations as part of a coordinated carrier strike against Japanese invasion forces in New Guinea on March 10, 1942. This action built on the task force's early experience from the Marshalls-Gilberts raids earlier that year, demonstrating improved carrier tactics in a more complex joint environment. Positioned in the Gulf of Papua, Yorktown launched its aircraft to support Allied efforts to disrupt Japanese landings at Lae and Salamaua, which threatened Allied positions in the Southwest Pacific. The strike began with Yorktown launching 52 aircraft, including 30 SBD-3 Dauntless dive bombers from Bombing Squadron 5 (VB-5) and Scouting Squadron 5 (VS-5), 12 TBD-1 Devastator torpedo bombers from Torpedo Squadron 5 (VT-5), and 10 F4F-3 Wildcat fighters from Fighting Squadron 42 (VF-42). These planes, flying in formation with aircraft from (Task Force 11), targeted Japanese shipping and shore facilities; Yorktown's dive bombers and torpedo planes focused on vessels at Salamaua, while fighters strafed ground targets at both locations. The attack achieved surprise, with no Japanese fighter opposition encountered, allowing the bombers to sink one transport and damage four others in the convoy, while destroying nine Japanese aircraft on the ground at the airfields. Fletcher's Task Force 17 provided critical air cover for U.S. Army Air Forces B-17 Flying Fortress bombers that simultaneously struck the convoy, enhancing the overall impact despite undetermined results from the land-based attack. This operation marked the first major joint U.S.-Australian effort in the theater, incorporating Australian reconnaissance from the ANZAC squadron to locate targets and test between naval and land-based forces. The strikes delayed Japanese reinforcements to , with Yorktown sustaining minimal losses: one SBD-3 shot down by antiaircraft fire and 11 aircraft slightly damaged, all but one returning safely by noon.

Battle of the Coral Sea

The Battle of the Coral Sea, fought from May 3 to 8, 1942, marked the first naval engagement conducted entirely by aircraft and the initial carrier-versus-carrier battle of the Pacific War. Task Force 17, centered on the aircraft carrier USS Yorktown (CV-5) and commanded by Rear Admiral Frank Jack Fletcher, joined forces with Task Force 11—comprising the carrier USS Lexington (CV-2) and supporting vessels—on May 1 in the southeastern Coral Sea, with Fletcher assuming overall command of the combined Allied force. This positioning was informed by U.S. Navy communications intelligence (COMINT) from decrypted Japanese JN-25 messages, which revealed plans for Operation MO, an amphibious invasion of Port Moresby, New Guinea, aimed at severing Allied supply lines. Allied reconnaissance efforts began intensifying on May 3, with PBY Catalina flying boats from bases in conducting long-range searches up to 700 miles into Sea, supplemented by scout planes from Yorktown and Lexington. On May 4, Fletcher launched a preemptive air strike from Yorktown against Japanese invasion forces assembling at in the , involving squadrons such as Bombing Five (VB-5) with SBD Dauntless dive bombers and Torpedo Five (VT-5) with TBD Devastator torpedo bombers, escorted by Fighting Squadron 42 (VF-42) Wildcats. The attack sank the destroyer Kikuzuki, the minelayer Okinoshima, and several smaller vessels, while damaging a and other craft, disrupting Japanese preparations without significant U.S. losses beyond three to operational causes. The composition during this phase included Yorktown, heavy cruisers USS , New Orleans, and Astoria, destroyers, and the addition of the Australian light cruiser HMAS from Allied Task Force 44. The battle escalated on May 7 when a Lexington scout plane sighted the Japanese light carrier Shoho escorting invasion transports off Misima Island; Fletcher ordered a combined strike from both U.S. carriers, launching 46 aircraft that overwhelmed Shoho with 13 bombs and seven torpedoes, sinking it by 10:30 a.m. and earning the famous radio call "Scratch one flat top." Japanese aircraft, meanwhile, struck the U.S. oiler Neosho and destroyer USS Sims, sinking the latter and leaving the former fatally damaged. On , mutual carrier strikes ensued after further reconnaissance and COMINT updates positioned the opposing fleets; aircraft from Yorktown and Lexington damaged the heavy carrier Shokaku with two bombs and a near miss, forcing its withdrawal, while Japanese planes from Shokaku and Zuikaku hit both U.S. carriers—Yorktown sustaining one 550-pound bomb amidships and Lexington absorbing two bombs and two torpedoes, igniting uncontrollable fires that led to its scuttling later that day. U.S. losses totaled the carrier Lexington, destroyer Sims, oiler Neosho (sunk ), and 66 aircraft, with Yorktown requiring repairs but remaining operational. Japanese losses included the carrier Shoho, destroyer Kikuzuki, and approximately 77 aircraft, alongside to Shokaku that sidelined it and depleted Zuikaku's air group. Tactically a draw due to comparable carrier , the battle represented a strategic Allied victory by thwarting the seaborne invasion of and halting Japanese expansion toward , compelling a shift to overland approaches via the . COMINT from stations at and proved pivotal, providing Fletcher with Japanese force dispositions and timelines that enabled proactive positioning of 17. The damaged Yorktown underwent rapid repairs at , allowing it to join the subsequent .

Battle of Midway

Task Force 17, centered on the repaired USS Yorktown (CV-5), departed Pearl Harbor on May 30, 1942, following emergency repairs after damage sustained in the Battle of the Coral Sea, and rendezvoused with Task Force 16 approximately 350 miles northeast of Midway Atoll on June 2. Under Rear Admiral Frank Jack Fletcher's overall command of the combined forces, Task Force 17 included the carrier Yorktown with its air group of 25 F4F-4 Wildcat fighters, 37 SBD-3 Dauntless dive bombers from squadrons VB-3 and VS-5, and 12 TBD-1 Devastator torpedo bombers from VT-3, screened by heavy cruisers USS Astoria (CA-34) and USS Portland (CA-33), and destroyers USS Hammann (DD-412), USS Hughes (DD-410), USS Morris (DD-417), USS Anderson (DD-411), and USS Russell (DD-414). Fletcher assumed tactical command, positioning the carriers to leverage intelligence from broken Japanese codes that revealed an impending attack on Midway, enabling a defensive ambush. The battle commenced on June 4, 1942, when U.S. scout planes located the Japanese carrier striking force under Vice Admiral , consisting of carriers Akagi, Kaga, Sōryū, and Hiryū. Fletcher directed an early strike, withholding Yorktown's aircraft until enemy positions were confirmed to maximize effectiveness; at approximately 1022, Yorktown launched 17 dive bombers from VB-3, 12 from VS-5, 10 torpedo bombers from VT-3, and 6 fighters. Torpedo Squadron VT-3 pressed a low-level attack on the Japanese carriers despite heavy antiaircraft fire and fighter opposition, with all 10 TBDs lost but their assault drawing away the Japanese and distracting defenses, setting the stage for the decisive dive-bomber strikes. Yorktown's dive bombers, arriving amid the chaos, joined aircraft from Enterprise and to fatally damage Sōryū with multiple bomb hits, rendering it unsalvageable; similar attacks sank Akagi and Kaga shortly thereafter. In retaliation, aircraft from the undamaged Hiryū struck Yorktown around 1100, scoring three bomb hits that started fires, disabled the , and killed or wounded dozens, temporarily forcing abandonment of the carrier. A subsequent torpedo attack by Hiryū planes at 1430 inflicted two hits, causing severe flooding and a 25-degree list, leading to the crew's evacuation; efforts to save Yorktown resumed on but were halted when approached undetected. On , I-168 fired four torpedoes, sinking Yorktown and the nearby Hammann, which had been providing antisubmarine protection and pump assistance. USS Gwin (DD-433) joined 17's screen on to bolster defenses amid the ongoing operations. Task Force 17 lost Yorktown, Hammann, and 37 aircraft during the engagement, with over 140 personnel killed or missing. Japanese forces suffered far heavier , including the sinking of all four carriers—Akagi, Kaga, Sōryū, and Hiryū—along with 248 aircraft, marking a decisive U.S. victory that shifted the balance of naval power in the Pacific. Fletcher's cautious yet timely decisions in coordinating the and strikes were pivotal to the outcome, though the loss of Yorktown ended his direct command of 17.

Eastern Solomons and Santa Cruz

Following the Battle of Midway, Task Force 17 was reformed under Rear Admiral George D. Murray with USS Hornet (CV-8) as its flagship, operating as part of Task Force 61 to support the Guadalcanal campaign by providing carrier-based air cover for Marine forces on the island. The task force's composition included Hornet's air group, comprising Fighting Squadron 72 (VF-72) with Grumman F4F Wildcat fighters, Bombing Squadron 8 (VB-8) and Scouting Squadron 8 (VS-8) with Douglas SBD Dauntless dive bombers, and Torpedo Squadron 8 (VT-8) with Grumman TBF Avenger torpedo bombers; supporting ships featured heavy cruisers USS Northampton (CA-26) and USS Pensacola (CA-24), light cruisers USS San Juan (CL-54) and USS San Diego (CL-53), and destroyers such as USS Morris (DD-417), USS Anderson (DD-411), and USS Mustin (DD-413). During the Battle of the Eastern Solomons from August 23 to 25, 1942, TF 17 coordinated with Task Force 16 (USS Enterprise) and Task Force 11 (USS Saratoga) under overall command of Vice Admiral Frank Jack Fletcher to intercept a Japanese convoy reinforcing Guadalcanal. On August 24, launched dive bombers and torpedo planes as part of a coordinated strike group that targeted the Japanese light carrier Ryūjō, scoring multiple and torpedo that caused fatal damage and led to its sinking later that day. Additional strikes from U.S. carriers damaged the heavy carriers Shōkaku and Zuikaku, though both evaded destruction; Japanese counterattacks focused on Enterprise, inflicting three that killed 74 sailors and required temporary repairs, but no U.S. carriers were lost. TF 17's aircraft provided defensive air cover over and patrol operations, contributing to the disruption of Japanese reinforcement efforts despite heavy attrition in the air battles, with the U.S. losing 20 aircraft to Japan's 92. Murray's coordination emphasized maintaining air superiority to protect Marine positions, though the engagement highlighted ongoing challenges in long-range carrier detection and strike coordination. By October 1942, TF 17, still under Murray's command with as flagship and a similar escort composition including cruisers , Pensacola, San Juan, and destroyers like Morris, rejoined Task Force 16 (Enterprise under Rear Admiral ) as part of Task Force 61 under Vice Admiral to counter a major Japanese offensive aimed at retaking . In the Battle of the from October 25 to 27, 1942, TF 17 launched multiple waves of dive bombers and torpedo planes starting at 0730 on October 26, striking the Japanese carriers Shōkaku (hit by four to six bombs, forcing its withdrawal) and Zuihō (severely damaged by bombs and torpedoes), while also damaging the cruiser Chikuma and a battleship. Japanese aircraft retaliated with coordinated dive-bomber and torpedo attacks, hitting with two bombs, two torpedoes, and a kamikaze-like crash at around 0910, igniting fires and leaving her dead in the water; Enterprise sustained two bomb hits but remained operational after damage control efforts. Despite rescue attempts, was abandoned by 1640 and scuttled by accompanying destroyers and O'Brien, though Japanese destroyers finished her off with torpedoes early on October 27, resulting in 140 deaths among her crew. The battle saw the U.S. lose 148 (many due to damage and shortages) compared to Japan's 99, with the higher Japanese pilot losses (around 148 ) proving more debilitating in the long term. While a tactical victory for Japan due to the sinking of —the last U.S. carrier available in the South Pacific at the time—the engagement allowed American forces to retain control of , as Japanese surface units withdrew without landing troops, ultimately contributing to TF 17's reorganization and effective disbandment by late 1942.

Legacy

Strategic Impact

Task Force 17's operations in the played a pivotal role in halting Japanese expansion toward by preventing the seaborne invasion of , forcing to abandon on 11 May 1942 and adopt a less viable overland approach that ultimately failed. Similarly, during the , TF 17's contributions helped thwart 's plan to capture the atoll as an advance base, derailing further offensives toward , , , and , and shifting the balance of Pacific sea power toward parity between and the . The task force's engagements underscored the critical importance of carrier-based air superiority and reconnaissance in modern naval warfare, as demonstrated by the first carrier-versus-carrier battle in the Coral Sea, where opposing fleets never sighted each other, emphasizing coordinated air strikes over traditional gunnery. Losses such as the sinking of USS Lexington in the Coral Sea and severe damage to USS Yorktown at Coral Sea—followed by rapid repairs that enabled Yorktown's redeployment to Midway, where it was sunk—highlighted key lessons in damage control and carrier resilience, influencing U.S. Navy doctrine to prioritize protected repair facilities and tactical flexibility in carrier deployments. In the , TF 17's actions in the Battle of the provided essential support to U.S. Marines by inflicting heavy losses on Japanese aircrews and carriers, delaying enemy reinforcements and buying critical time for Allied forces to consolidate their positions on the island. These battles, though costly in terms of the loss of and damage to USS Enterprise, weakened Japan's carrier strength and enabled the U.S. to assume the initiative in the chain. Beyond immediate tactical outcomes, TF 17's successes boosted American morale at a crucial juncture following early war setbacks, fostering confidence in carrier-centric operations and informing the evolution of U.S. toward larger, more integrated fast carrier task forces, such as the Third Fleet's TF 38, which incorporated multiple carriers, battleships, and escorts for sustained offensive power by 1944. A hallmark of TF 17's effectiveness was its integration of from breaking the Japanese JN-25 code, which provided actionable insights into enemy intentions for the Sea and Midway operations, allowing precise positioning of forces and contributing to the broader Allied counteroffensive in the Pacific.

Reorganization and Dissolution

Following the , the sinking of on 7 June 1942 severely depleted Task Force 17's capabilities, prompting Rear Admiral to transfer tactical command of the task force's surviving elements to Rear Admiral of Task Force 16. This merger integrated TF 17's remaining ships, including those carrying Yorktown survivors, under Spruance's operational control for the return to . Fletcher himself was promoted to shortly thereafter and reassigned to command Task Force 61 in the , overseeing carrier support for the invasion under Vice Admiral . Task Force 17 was reconstituted in August 1942, centered on USS Hornet (CV-8) as flagship and commanded by Rear Admiral George D. Murray. Departing Pearl Harbor on 17 August, the reformed TF 17—comprising Hornet, the battleship USS North Carolina (BB-55), cruisers, and destroyers—joined other forces in the South Pacific Area under Vice Admiral Robert L. Ghormley (replaced by William F. Halsey on 18 October) to provide air cover for the ongoing Guadalcanal campaign. This integration marked TF 17's role in the broader South Pacific offensive, though it operated alongside rather than independently of other task groups. The loss of on 26 October 1942 during the Battle of the Santa Cruz Islands, where the carrier suffered multiple and hits and was scuttled by accompanying destroyers, effectively ended TF 17's viability as a standalone unit. Surviving ships from TF 17, including cruisers and destroyers, were absorbed into Task Force 16 centered on the damaged USS Enterprise (CV-6), which required repairs before rejoining operations. TF 17 was administratively disbanded in November 1942, with its personnel and assets redistributed to emerging task organizations supporting the .
