Naval Base Woodlark Island
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. History On June 21, 1943, American forces came ashore on southern New Georgia, and then on June 30, landed on Woodlark Island as part of Operation Chronicle. Guasopa Bay lacked a usable dock so the landing were done with LST (3), LST landing ships. Landing with the United States Army and United States Marine Corps at Guasopa was the US Navy's Seabee 60th Construction Battalion, and the 20th Construction. The 500 men with the 60th Construction Battalion started work on the airfield and its facilities. The 200 men with the 20th Construction Battalion started work on the harbor, b ...

Milne Bay Province
Milne Bay is a province of Papua New Guinea. Its capital is Alotau. The province covers 14,345 km2 of land and 252,990 km2 of sea, within the province there are more than 600 islands, about 160 of which are inhabited. The province has about 276,000 inhabitants, speaking about 48 languages, most of which belong to the Eastern Malayo-Polynesian branch of the Austronesian language family. Economically the province is dependent upon tourism, oil palm, and gold mining on Misima Island; in addition to these larger industries there are many small-scale village projects in cocoa and copra cultivation. The World War II Battle of Milne Bay took place in the province. Culturally the Milne Bay region is sometimes referred to as the Massim, a term originating from the name of Misima Island. Massim societies are usually characterized by matrilineal descent, elaborate mortuary sequences and complex systems of ritual exchange including the Kula ring. From island group to island gr ...

Pontoon Bridge
A pontoon bridge (or ponton bridge), also known as a floating bridge, is a bridge that uses float (nautical), floats or shallow-draft (hull), draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry. Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use that can carry highway traffic; generally, the relatively high potential for collapse and sinking (e.g. due to waves and collisions) and high continuous maintenance costs makes pontoons unattractive for most civilian construction. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored Pier (architecture), piers (such as in deep water). Such bridges can require a section that is elevated or can be raised or removed to allow waterborne traffic to pass. Notable permanent pontoo ...

Naval Base Brisbane
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, it operated as a base for patrol aircraft and convoy escort aircraft to protect the last leg of the Pacific War to the South West Pacific theatre of World War II, Southwest Pacific. As the US Navy expanded in the Leapfrogging (strategy), 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.

US Naval Base New Guinea
US Naval Base New Guinea was number of United States Navy bases on the island of New Guinea (then divided into Dutch New Guinea, the Territory of New Guinea and the Territory of Papua) 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.

Naval Base Milne Bay
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. History Naval ...

US Naval Advance Bases
US Naval Advance Bases were built globally by the United States Navy during World War 2, World War II to support and project U.S. naval operations worldwide. A few were built on Allies of World War II, 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 CONUS, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bomber
A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch aerial torpedo, torpedoes, or deploy air-launched cruise missiles. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. Bombs were first dropped from an aircraft during the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Seco ...

Fighter Plane
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual ro ...

Quarry
A quarry is a type of open-pit mining, open-pit mine in which dimension stone, rock (geology), rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. History For thousands of years, only hand tools had been used in quarries. In the eighteenth century, the use of drilling and blasting operations was mastered. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Scoria, Cinder *Clay *Coal *Construction aggregate (sand and gravel) *Coquina *Diabase *Gabbro *Granite *Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone *Slate *Travertine Methods of quarrying The method of removal of stones from their natural bed by using different operations is called quarryin ...

Coral
Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact Colony (biology), colonies of many identical individual polyp (zoology), polyps. Coral species include the important Coral reef, reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many cloning, genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form ...
