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.[1] [2]
Naval Base Milne Bay started as a small Royal Australian Navy in 1942 as part of the New Guinea campaign. On May 23, 1943 Seabees of 55th Battalion started construction of a PT boat Advance Base Six on the south side of Milne bay at Kana Kopa, including an engine-overhaul shop. On June 29 and 30, 1943 Naval Base Milne Bay PT boats took part in the attacks on Salamaua Bay and Nassau Bay. The Seabees of the 84th Battalion built Naval Base Milne Bay into a major installation. Seabees built depots for transshipment and staging. Seabees built an overhaul facility for PT boats. Naval Base Milne Bay became a major destroyer base. Milne Bay is 20 miles long, providing a large protected harbor. For land operations, Seabees had to cut into the wet tropical jungle that is the shore of the bay. Seabees built the supply depots near the village of Gamadodo.[1] Malaria was major problem at Naval Base Milne Bay installations, also tropical skin diseases.[3] [4] On July 31, 1943 Seabees started construction on a US Navy seaplane base, 10 miles south of the entrance to Milne Bay at Jenkins Bay. On October 21, 1943 Seabees 91st Battalion arrived at Ladava a replaced 84th Battalion. Seabees 91st Battalion began construction on a destroyer repair base at Gohora Bay, Ladava. An amphibious training center at and large depot was built at Swinger Bay in Alotau. Base Milne Bay was one of a number of staging places for the Battle of Arawe on New Britain. By July 1945 the bases at Naval Base Milne Bay were too far away from the action, and most of the base was packed up by the Seabees and moved to more forward bases in the Philippines and Okinawa.[1] [2]
Naval Base Milne Bay headquarters was built at Ladava at the west end of Milne Bay, called Ladava Navy Base. For Ladava headquarters, Seabees built: piers, jetties, roads, an electric power station, a communication center, a supply depot, a hospital unit, and barracks for 1,000 troops at -10.3333°N 150.3519°W. Next to Ladava in Gohora Bay was the Fleet anchorage and the destroyer repair depot at -10.3519°N 150.3494°W. Some of the destroyers serviced at the base were: USS Hogan, USS Flusser (DD-368), USS Shaw (DD-373), USS Drayton (DD-366), USS Smith (DD-378), USS Helm (DD-388), USS Mugford (DD-389), USS Warrington (DD-383), USS Taylor (DD-468), USS Daly, and the USS Perkins (DD-377). USS ARD-9 a Auxiliary floating drydock for ship repair arrived at Milne Bay on February 6, 1944. A major PT Boat repair base was built at Ladava. Seabees built a 5-mile road from Ladava Navy Base along the north shore of Milne Bay, linking the north shore bases and ship ports. United States Seventh Fleet used the anchorage at -10.3379°N 150.3482°W and used the bases for staging upcoming sland-hopping campaigns. Submarine chasers, like SC-731 and SC-703, operated out of Naval Base Milne Bay. USS Trinity (AO-13) a fleet oiler was one of the ships that helped the ships at Milne Bay stay on the move. The USS Achilles (ARL-41), a Landing Craft Repair Ship, was at the bay from June 1943 to September 1943. At its peak over 20,000 troops were stationed at Naval Base Milne Bay.[1] [2] [5]
The first Seabee installation built was the PT boat base built at Kana Kopa (Kana Kope) on the south side and near the entrance of Milne Bay at -10.4839°N 150.6518°W. Kana Kopa had been used as anchorage for the Royal Australian Navy in 1942 and supported the August 1942 Battle of Milne Bay. The US Navy PT Boat Advance Base Six opened on December 11, 1942. The 55th Seabees enlarged the PT Boat base on May 23, 1943. Added to the base was: camp for 800 troops, large supply depot, water storage tanks, wharf, pontoon dry docks for repair work, and an engine overhaul depot. USS Oyster Bay (AGP-6), USS Hilo (AGP-2), and USS Wachapreague (AGP-8), operated as PT boat tenders at Kana Kopa in 1944. Naval Base Milne Bay supported a second PT Boat Base on Fergusson Island north of Milne Bay. In June 1944 Seabees moved the base to Dreger Harbour, near Finschafen.

See main article: Samarai Advanced Seaplane Base. Samarai Seaplane Base located on Samarai Island used as a US Navy seaplane base at -10.61°N 150.662°W. The seaplane base shore facilities were on Sariba Island, just to the east of Samarai Island at -10.5968°N 150.6879°W.[1] The USS Half Moon, a Seaplane tender, was stationed at the base for support from October 1943 to December 1943. VPB-52 a US Navy Patrol Bombing Squadron stationed at the base. The Seabee 84th Battalion built a plane ramp on Samarai Island. On Sariba Island they built a camp for 270 troops, a small boat pier, communication center, headquarters, mess hall, and aviation-gasoline tank farm, supply depot. A roll of the base was to patrol the shipping lanes to Australia and did reconnaissance work. The night-flying "Black Cat" PBY Squadron, VPB-11, VP-33, VP-34, and cat VP-101 was stationed at the base. The base also operated a crash boat base at the camp, with Rescue Boat C-9485. Fleet PO Box was 421.[2] [6] [7] [8]
Amphibious Construction Battalion 2 and 105th Battalion Seabees built a large amphibious training center at Swinger Bay at -10.3038°N 150.4133°W in the city of Alotau. Troops trained in amphibious ship landings, with two programs one for officers and one for troops. The center had quonset hut camp for 1,500 troops, mess hall, vast supply depot, class rooms, a 2,000 foot waterfront. Seabees did a massive grading project to space for the center. The center opened in January 1944. Seventh Amphibious Force moved from Toorbul, Queensland to the Alotau Base in 1944, and in March 1945 moved out of Alotau to U.S. Naval Base Subic Bay.[9] US Army 32d Infantry Division and 41st Infantry Division are some of the units that trained at the center, also the 1st Marine Division.

Gili Gili Dock was Naval loading and unloading dock, with both a jetty and pontoon wharf at Gili Gili (also spelled Gill Gill). On September 6, 1942 the ship MV Anshun a 1930 ship was sunk at Gili Gili Dock by Japanese cruiser Tenryū. She was refloated and repaired. Gili Gili Base was at -10.3167°N 150.3809°W, just west of Swinger Bay and the Swinger Bay Base. Turnbull Field No. 3 Strip, was inland from the Gili Gili Dock and Swinger Bay Base amphibious training center just to the east of Gili Gili Dock. Gili Gili also became a US Army staging area with a large tent camp. Feet Post Office FPO# 717 SF Gilli Gilli, Milne Bay.[11] [1] [2]
The Gamadodo Center was south of Ladava, at Gamadodo, now called Gibara, at -10.4082°N 150.3763°W. At Gamadodo a Amphibious Construction Battalion 1 built a sawmill to supply lumber to the bases in Milne Bay. As the size of the Naval Base Milne Bay increased more supplies were needed so a cargo pier and a very large depot were built at Gamadodo. Soon Liberty Ships and Victory ships were unloading supplies. Seabees built a large staging camp for 10,000 troops, and a pontoon assembly depot, to assemble pontoons that were shipped in parts to save space on ships. Fleet Post Office FPO# 167 SF Gamadodo, Milne Bay.[12] An ammunition depot was built outside of the camp.[2]
In late 1943 Milne Bay Submarine Base opened an advanced submarine base with submarines from Naval Base Brisbane. The US Navy submarine tender USS Fulton was station at Milne Bay Submarine Base from 29 October 1943 to 17 March 1944.[13] [14]
Amphibious Construction Battalion 2 built a 500-bed Naval hospital and 3,000 bed rest and recovery center was built at Hilimoi bay on the south side of Milne Bay at -10.4167°N 150.45°W. Hilimoi is five miles east of Gamadodo depot and center. Also called Hilimoi Mission. The hospital was shipped to a more forward base in July 1945.
