Task Force 61 seems to have first been formed in advance of the Guadalcanal Campaign of 1942. Admiral Robert L. Ghormley, Commander, South Pacific Area, issued his Operation Plan No. 1–42 on 16 July 1942. It was to govern the execution of Task One which was to be divided into three phases. The first would be a rehearsal in the Fiji Islands; the second would be the seizure and occupation of Tulagi and Guadalcanal. Additionally, the task force executed Operation Cleanslate on the Russell Islands in August 1942. The projected occupation of Ndeni in the Santa Cruz Islands would be the third and final phase. Operation Plan No. 1–42 organized two forces, Task Forces 61 and 63. The Expeditionary Force of eighty-two ships, was to be commanded by Vice-Admiral Frank Jack Fletcher, and included the amphibious force of Task Group 61.2 under Rear Admiral Richmond K. Turner, escorted by the vessels of Task Group 61.1 Rear Admiral Leigh Noyes. The main landing force was to be the 1st Marine Division. Later, in October 1942, the Task Force, now under Rear Admiral Thomas C. Kinkaid, confronted a force directed by Japanese Admiral Isoroku Yamamoto in the same area. In late October, the Task Force consisted of the USS Enterprise, USS South Dakota, the cruisers USS Portland and USS San Juan, and eight destroyers. The Task Force formed one of the two U.S. carrier groups that took part in the Battle of the Santa Cruz Islands. As such it represented the combined command of Task Force 11, Task Force 16 and Task Force 18. Task Force 61 was dissolved in the Pacific Theater and became Task Group 92.4 while TF-61 was reactivated in the Atlantic under the Royal Navy command, and participated in convoy escort duties, although initially it included US Navy Destroyer Division 60, Destroyer Escort Division 5, and a number of United States Coast Guard and Free French Navy vessels. In May 1944 it included, Richelieu,, the Royal Netherlands Navylight cruiser HNLMS Tromp, 21st Carrier Squadron, and HM Destroyers,,, and.
