"Bunch" sailed for Okinawa on the 19th, and reached Hagushi on the 22nd. She remained at anchor off Hagushi until the 25th, when she moved to Kerama Retto for a four-day availability to make repairs to her sonar which had failed during the voyage back from Guam. On the 30th, the high-speed transport received orders for her next mission, the occupation of Iheya Shima. Though scheduled to begin early on the 31st, the Iheya Shima operation had to be postponed because of foggy weather. The action finally began on 2 June with "Bunch" in a standby role. Inclement weather and an excellent combat air patrol (CAP) took care of enemy planes, and "Bunch" remained at anchor during the night and forenoon. A pair of approaching typhoons, though, compelled the assault group to get underway and seek shelter in the lee provided by a small bay north of the Motobu Peninsula.
