Operation Chronicle was the Allied invasion of Woodlark and Kiriwina Islands, in the South West Pacific, during World War II. The operation was a subordinate action that formed part of the wider Operation Cartwheel, the advance towards Rabaul. An early planning name for this operation was Operation Coronet. Preliminary actions commenced on 23–24 June 1943 when small reconnaissance parties were landed on both islands. The main operation was executed without opposition on 30 June 1943. Around 16,800 personnel took part, divided into two forces. The United States Army provided the majority of ground troops, which were supported by a United States Marine Corps defense battalion as well as U.S. and Australian aircraft and naval vessels.
USS Porcupine (IX-126), an Armadillo-class tanker designated an unclassified miscellaneous vessel, was the second ship of the United States Navy to be named for the porcupine.
USS Lake County (LST-880) was an LST-542-class tank landing ship built for the United States Navy during World War II. Named after counties in twelve U.S. states, she was the only U.S. Naval vessel to bear the name.
USS Sonoma (AT-12) was a Sonoma-class fleet tug which had the distinction of serving her country during World War I and World War II. For her work as a tugboat in some very dangerous battle areas, she earned five battle stars during World War II. She ended her battle career when she was sunk by a crashing Japanese bomber.
USS Mahnomen County (LST-912) was an LST-542-class tank landing ship built for the United States Navy during World War II. Like many of her class, she was not named and is properly referred to by her hull designation. She was later named after Mahnomen County, Minnesota, and was the only US Navy vessel to bear the name.

US Naval Advance Bases were built globally by the United States Navy during World War II to support and project U.S. naval operations worldwide. A few were built on Allied soil, but most were captured enemy facilities or completely new. Advance bases provided the fleet with support to keep ships tactically available with repair and supply depots of facilities, rather than return them to the continental United States. Before Japan declared war on the United States the U.S. Navy had a single fleet-sized advanced base in the Territory of Hawaii at Naval Station Pearl Harbor. During the war the U.S. Navy Seabees built over 400 advance bases categorized by size. Naval bases were either Lions or Cubs while airfields were either Oaks or Acorns. Lions and Oaks were major facilities while Cubs and Acorns were minor. PT Boats typically would get a Cub and airfields with single runways were Acorns. The larger bases could provide refueling and overhaul; loading of troopship and cargo ships; and preparing amphibious assault ships. Some became major repair depots. The Seabees developed auxiliary floating drydocks were able to repair battle damage and do regular maintenance in the field saving ships trans-pacific trips for repair. A few bases also were developed to be R and R for all U.S. personnel. Most Advance Bases were built by the US Navy's Seabees in Naval Construction Battalions (CBs). At the start of the war civilian contractors were employed in construction. The Seabees in World War II built most of the airfields used by the United States Army Air Forces and United States Marine Corps, as they had the ships and cranes needed to transport the vast amount of equipment needed at the advance bases. The US Army and United States Coast Guard also operated out of many of these facilities. Seabees could build new or repair damaged runways, and with advancements in heavy bomber technology lengthen runways as needed. A few Naval Advance Bases were built for the Korean War and Vietnam War.
Naval Base Milne Bay, also called Naval Advance Base Milne Bay, was new major United States Navy sea and airbase base built on Milne Bay in Milne Bay Province in south-eastern Papua New Guinea. By spring 1943, the build up of the US Navy to support the Pacific War had caused overcrowding at the ports on the east coast of Australia. To help, Seabees departed Naval Base Brisbane on June 19, 1943 to set up a new base in Milne Bay. Naval Base Milne Bay headquarters was at Ladava Navy Base. The Royal Australian Navy already had a small base in Milne Bay: HMAS Ladava. Australians were able to defend and keep Milne Bay in the Battle of Milne Bay in 1942. Naval Base Milne Bay was built during World War II to support the many ships and aircraft fighting and patrolling in the South West Pacific theatre of war. Ladava Navy Base provided a large protective US Navy fleet anchorage at Gahora Bay next to Ladava. At Naval Base Milne Bay, Seabees built a large Naval facility.
Naval Base Brisbane was a major United States Navy base built in the early part of World War II at Brisbane, Queensland, Australia. At first, operated as a base for patrol aircraft and convoy escort aircraft to protect the last leg of the Pacific War to the Southwest Pacific. As the US Navy expanded in the island hopping campaign, Naval Base Brisbane expanded to include a submarine base, repair depot, seaplane base and other facilities. US Navy operations started on April 14, 1942, and ended after the war in 1945.
Naval Base Woodlark Island was a United States Navy base built during World War II on Woodlark Island on Papua New Guinea. The US Navy built a PT boat base, boat repair depot, and harbor facilities at the city of Guasopa to support the Pacific War in 1943. The Harbor facilities was also built to support the US Navy in building the Narewa Airfield on the island. The base was part of the New Guinea campaign.
Naval Base Finschhafen was a United States Navy base built during World War II at Finschhafen on the Huon Peninsula in Morobe Province of Papua New Guinea. The US Navy built a PT boat base, Dreger Harbor PT Boat Base, boat repair depot, and harbor facilities at Dreger Harbour and Langemak Bay to support the Pacific War in 1943. Harbor was also built to support the US Navy in building 6,000-foot Finschafen Airfield, also called Dreger Field, now Finschhafen Airport on the island. The base was part of the New Guinea campaign.
US Naval Base New Guinea was number of United States Navy bases on the island of New Guinea during World War II. Australia entered World War II on 3 September 1939, being a self-governing nation within the British Empire. The United States formally entered the war on 7 December 1941, following the attack on Pearl Harbor by the Empire of Japan. Following the attack on Pearl Harbor, Japan quickly took over much of the South Pacific Ocean. The United States lost key naval bases in the South Pacific, including Naval Base Manila and Naval Base Subic Bay, both lost in the 1941–42 invasion of the Philippines. Also lost were Naval Base Guam and Wake Atoll. As such, the United States Armed Forces needed new bases in the South West Pacific for staging attacks on Japan's southern empire. The United States built bases first in Australia, then in New Guinea.
The United States Navy held a number of bases in the Philippines Islands in the Pacific Ocean. Most were built by the US Navy Seabees, Naval Construction Battalions, during World War II. The US Naval Bases in Philippines were lost to the Empire of Japan in December 1941 during the Philippines campaign of 1941–1942. In February 1945 the United States Armed Forces retook the Philippines in the Battle of Manila in 1945. Before the captured US bases on Luzon were retaken the US Navy Seabees built a new large base, Leyte-Samar Naval Base, on the Philippine Island of Leyte, starting in October 1944.
