The great task force sortied once more from Ulithi 14 March to support the Okinawa operation, last stop on the island road to Japan. In heavy strikes 18–19 March the carrier forces inflicted great damage on Okinawa in preparation for the invasion, and "Harrison" shot down another attacking enemy aircraft. Attacks against Japanese airfields in the home islands were also launched, cutting down significantly the air opposition over Okinawa during the initial assault. After the Marines stormed ashore 1 April, the carrier groups and their destroyers turned to direct support of the landing. As a Japanese task force, built around the giant battleship "Yamato", sortied from the inland sea to attack the beaches at Okinawa, TF 58 aircraft delivered a skillful and effective attack, sinking "Yamato" and five other ships while suffering only small losses.
