From 26 March to 9 April, the BPF attacked the airfields with each two-day period of flying operations followed by two or three days required to replenish fuel, ammunition and other supplies. While the precise details on activities of the carrier's squadrons are not readily available, it is known that the commanding officer of 854 Squadron was forced to ditch his Avenger on the morning of 27 March with the loss of both his crewmen; he was ultimately rescued that evening by an American submarine. On the afternoon of 6 April, four kamikaze aircraft evaded detection and interception by the CAP, and one, a Yokosuka D4Y3 "Judy" dive bomber, attacked "Illustrious" in a steep dive. The light AA guns managed to sever its port wing so that it missed the ship, although its starboard wingtip shattered the Type 272's radome mounted on the front of the bridge. When the bomb that it was carrying detonated in the water only from the side of the ship, the resulting shock wave badly damaged two Corsairs parked on the deck and severely shook the ship. The initial damage assessment was that little harm had been done, although vibrations had worsened, but this was incorrect as the damage to the hull structure and plating proved to be extensive. Vice Admiral Sir Bernard Rawlings, commander of Task Force 57, ordered the recently arrived "Formidable" to join the task force to replace "Illustrious" on 8 April. In the meantime, she continued to conduct operations with the rest of the fleet. On 12 and 13 April, the BPF switched targets to airfields in northern Formosa and her sister joined the task force on 14 April. Since the beginning of the operation, her aircraft had flown 234 offensive and 209 defensive sorties, claiming at least two aircraft shot down. Her own losses were two Avengers and three Corsairs lost in action and one Avenger and six Corsairs due to non-combat causes.
