Kimberly joined the Pacific Fleet in time to participate in the Gilbert Islands operation. After returning to San Francisco in January 1944, she joined the other ships of her squadron in the Aleutians.
Operating from Massacre Bay, Attu from the beginning of 1944 through midsummer, the squadron participated in two raids. In March, it screened light cruiser Richmond in the first operation into the Sea of Okhotsk to search for a convoy and conduct shore bombardment, but ran into a major storm which cause topside damage to several ships. In June, it sortied again in the screen of cruisers Chester, Pensacola and Concord for a bombardment of Paramushiro Island off the tip of the Kamchatka Peninsula.
After overhaul, the squadron joined other forces at Manus for the invasion of the Philippines at Leyte and remained intact for the landings at Lingayen Gulf, Luzon. Less Kimberly and William D. Porter, the squadron then operated out of Subic Bay for the operation against Corregidor and other defenses of Manila Bay.
After Manila was taken, Young followed the Seventh Fleet south to Mindanao while the remainder of the squadron moved north to Okinawa for fire support and radar picket duty before returning to San Francisco at the end of the war.
