Ta What was a TU (Task Unit( This arrangement was typically abbreviated, so references like TF 11 are commonly seen. Likewise the force is broken down as following: task force, task group, task unit, and task element. In addition, a task force could be broken into several task groups,[2]identified by decimal points, as in TG 11.2, and finally task units, as in TU 11.2.1. Individual ships are task elements, for example TE 11.2.1.2 would be the second ship in TU 11.2.1. 21 March 45: Sederstrom departed the Western Carolines for the Ryukus in the screen of the escort carriers of Support Carrier Unit 1 and arrived off the southern tip.

On the 22d, she was targeted by akamikaze, but her antiaircraft guns damaged the planesufficiently to cause it to crash into the water about 10 feet off the starboard bow. Gasoline and pieces of metal showered the bridge and forecastle, but major damage was avoided. One man, forced overboard during the action, was quickly recovered. Regarding this operation per the destroyer escort historical website The invasion of Okinawa in April 1945 initiated a new and deadly facet of destroyer escort service in the Pacific. By this time, the Japanese were relying heavily on suicide aircraft known as kamikazes. These planes had been inflicting severe damage on the American fleet since the invasion of the Philippines in 1944. Kamikazes became more and more dangerous as American forces neared the Japanese home islands. Once US forces landed on Okinawa, the Japanese unleashed the full fury of their kamikaze forces. In an attempt to minimize the losses to its capital ships and amphibious fleet, the Navy sent destroyers and destroyer escorts out to picket stations around Okinawa. From these stations, the small combatants would use their radar to detect incoming kamikazes and then warn the fleet at Okinawa, which would send fighter planes out to shoot down in the incoming planes. Once the Japanese realized what the destroyers and destroyer escorts were doing, they began targeting the ships to remove their early warning. Radar picket duty then became the deadliest job in the Navy's history. Over the next few months, more than 300 ships were hit by kamikazes at Okinawa, most of them destroyers and destroyer escorts. More than 5,000 sailors were killed during the battle, or more than the Navy had lost in every other battle in its history combined. Nevertheless, the destroyer escorts remained on station with the larger destroyers and continued to provide the early warning throughout the campaign.3
In early May, the DE escorted Arkansas out of the combat area; and, on the 18th, Sederstrom herself left the Eyukyus area.

The amphibians did their amphibious tasks of assault landing two corps so expeditiously and so well that the fact that these tasks had to be accomplished, if the Tenth Army was to be put (a) COMPHIBGRP Seven (CTG 5U) Okinawa Action Report, 25 May 1945, part II, paras 4, 7, pp. 1, 2; (b) COMPHIBGRP 12 (CTF 55) Okinawa Action Report, 31 JuL 1945, Part II, para 2 p. 1. Interview with Admiral John Lalie Hall, USN (Ret), 1-6 Nov. 1961. Hereafter Hall, 1084 Amphibians Came To Conquer on a successful course, largely has been forgotten. The main naval struggle was not between the naval amphibians and unhospitable beaches or between Japanese dug in at the beachhead and on-rushing landing craft, but between U. S. radar picket ships, their supporting small craft, and the fighter aircraft on the one side and the Japanese kamikaze on the other side. As one commodore stated the case from the viewpoint of the radar picket ship: "Never in the annals of our glorious naval history have naval forces done so much with so little against such odds for so long a period." 33 Without in any way indicating a lack of appreciation of this particularly bloody part of the Navy's Okinawa campaign, the amphibious assault landings will be described.
