June the New Georgia campaign began. McCalla departed Efate on 26 June to escort troop transports to Rendova Island. On 30 June, after the landings, the force was attacked by Japanese aircraft. As the first wave, torpedo planes, pressed in, the transport was torpedoed. McCallas guns splashed one with two possibles; in the second wave, dive bombers, they splashed one and assisted with another kill. She then rescued 98 of McCawleys crew. By 5 July, McCalla was back in the New Georgia area to screen the landing of Marine Raiders at Rice Anchorage. On 9 July, she took part in the bombardment of Munda airfield and then returned to escort and antisubmarine work. At the end of September McCalla and the destroyer collided, with serious damage to McCallas bow. Temporary repairs were effected at Purvis Bay, Florida Island, before she departed for shipyard repairs at Mare Island Naval Shipyard. While en route, she rescued 868 survivors of the torpedoed troop transport . 1944–1946 Ready for war duty again by 8 January 1944, McCalla got underway for the South Pacific.
