Task Force 38 was the designation for the fast carrier task force of the United States Pacific Fleet during the final year of the Pacific War (World War II), operating as a principal striking arm in the Pacific Theater of World War II and coordinating with the United States Seventh Fleet, Fifth Fleet (United States Navy), and allied units. The force provided concentrated carrier air power in major operations such as the Battle of Leyte Gulf, the Battle of the Philippine Sea, and the Battle of Okinawa, projecting force from fleet carriers and escort carriers while integrating destroyers, cruisers, and logistics groups. Command relationships alternated with the designation used by Admiral Chester W. Nimitz's command structure and reflected strategic shifts directed by the Joint Chiefs of Staff, Admiral William F. Halsey Jr., and Admiral Raymond A. Spruance.

Origins and formation

The fast carrier force emerged from prewar developments in United States Navy doctrine influenced by the Washington Naval Treaty, lessons from the Battle of Midway, and carrier task force concepts tested in the Guadalcanal Campaign and the Solomon Islands campaign. Reorganization after operations in the Solomon Islands and the Gilbert and Marshall Islands campaign consolidated fleet carriers such as USS Enterprise (CV-6), USS Yorktown (CV-10), and USS Lexington (CV-16) under a single numbered task force to improve coordination with fleet oilers of the Service Force (United States Navy) and screening by Destroyer Squadron 23. Operational planning drew on intelligence from Fleet Radio Unit Pacific and cryptanalysis successes attributed to Station HYPO.

Operational history

The force conducted sustained carrier operations across the Philippine Sea, Marianas campaign, and the Leyte campaign (1944) in 1944, striking Japanese Empire strongpoints, airfields, and naval units while supporting amphibious assaults at Saipan, Tinian, and Guam. During late 1944 and 1945 it executed raids against the Tokyo Bay area, the Ryukyu Islands, and the Sakishima Islands, providing close air support for the Battle of Iwo Jima and the Battle of Okinawa and interdicting Japanese shipping in the South China Sea. The task force alternated between offensive sorties and replenishment cycles with the Service Force, US Pacific Fleet, often responding to directives from Admiral Chester W. Nimitz and operational tasking from the Joint Chiefs of Staff throughout the Final months of World War II.

Organization and composition

Composed principally of fleet carriers, light carriers, and escort carriers drawn from carrier air groups such as Carrier Air Group 5 and Carrier Air Group 9, the task force integrated Battleship Division 1 and Cruiser Division 4 elements for anti-air and surface action, with screening provided by Destroyer Squadron 54 and Destroyer Squadron 21 (United States Navy). Logistic support was furnished by the Service Squadron 10 fleet oiler groups and escorting oilers like USS Cimarron (AO-22). Air groups embarked squadrons flying the Grumman F6F Hellcat, Vought F4U Corsair, Grumman TBF Avenger, and later models such as the Curtiss SB2C Helldiver, while radar picket duties were assigned to converted destroyers and escort carriers like USS Gambier Bay (CVE-73).

Major engagements and campaigns

The force played a central role in the Battle of the Philippine Sea ("Great Marianas Turkey Shoot"), inflicting severe losses on Imperial Japanese Navy carrier air power and enabling the Marianas campaign landings. In the Battle of Leyte Gulf its carrier groups supported the Leyte landings and engaged in strikes during clashes with the Japanese Southern Force and Center Force (Japan), contributing to the sinking of capital ships and cruisers. During the Ryukyus campaign and Battle of Okinawa the task force executed pre-invasion bombardments, carrier strikes against Kamikaze bases, and night raids on airfields in the Japanese Home Islands, directly supporting operations that culminated in the Surrender of Japan.

Tactical innovations and equipment

Operational practice emphasized task group coordination, combined arms integration of carrier air power with surface gunfire from Battleship Division 2, and extended underway replenishment pioneered by Service Squadron 10 to sustain high-tempo carrier strikes far from home ports. Innovations included coordinated combat air patrol (CAP) tactics using radar-equipped fighters, improved fighter direction from carrier CIC centers influenced by personnel experienced at Battle of Midway, and the development of radar picket screens using destroyers and escort carriers to provide early warning against Kamikaze attacks. Aircraft types and ordnance evolved to include heavier bombs and rockets for anti-shipping strikes, while carriers adopted improved armored flight decks and damage-control procedures modeled after lessons from the Battle of Coral Sea and carrier losses in the early war.

Commanders and notable personnel

Senior commanders associated with the force's operations included Admirals drawn from the United States Pacific Fleet command group such as William F. Halsey Jr. and Raymond A. Spruance, with staff and air group leaders like Rear Admirals and Carrier Air Group commanders who had served in campaigns including Midway and Solomon Islands campaign. Notable ship captains, air group aces, and destroyer commanders who served in the force had prior combat experience at Guadalcanal, Battle of the Philippine Sea, and other major Pacific engagements, and many later received awards such as the Medal of Honor, Navy Cross, and Distinguished Flying Cross for actions during carrier operations and amphibious support missions.
