General Dynamics Electric Boat
General Dynamics Electric Boat (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut, New London, Connecticut. History The company was founded in 1899 by Isaac Rice (businessman), Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible ship designs, which were developed at Lewis Nixon (naval architect), Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. ''Holland VI'' was the first submarine that this shipyard built, which became when it was commissioned into the United States Navy on April 11, 1900—the first submarine to be officially commissioned.

Shore Batteries
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. Land usage Historically the term "battery" referred to a cluster of cannons in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannons in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used as a ...

Lombok Strait
The Lombok Strait () is a strait of the Bali Sea connecting to the Indian Ocean, and is located between the islands of Bali and Lombok in Indonesia. The Gili Islands are on the Lombok side. Its narrowest point is at its southern opening, with a width of about between the islands of Lombok and Nusa Penida, in the middle of the strait. At the northern opening, it is across. Its total length is about . As it is minimum deep—much deeper than the Strait of Malacca—ships that draw too much water to pass through the Malacca Strait (so-called "post Malaccamax" vessels) often use the Lombok Strait, instead. The Lombok Strait is notable as one of the main passages for the Indonesian Throughflow (ITF) that exchanges water between the Indian Ocean and the Pacific Ocean. It is also part of the biogeography, biogeographical boundary between the fauna of the Indomalayan realm and the distinctly different fauna of Australasian realm, Australasia. The boundary is known as the Wallace Line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Makassar Strait
Makassar Strait () is a strait between the islands of Borneo and Sulawesi in Indonesia. To the north it joins the Celebes Sea, while to the south it meets the Java Sea. To the northeast, it forms the Sangkulirang Bay south of the Mangkalihat Peninsula. The strait is an important regional shipping route in Southeast Asia. The Mahakam River and Karangan River of Borneo empty into the strait. Ports along the strait include Balikpapan and Bontang in Borneo, and Makassar, Palu, and Parepare in Sulawesi. The city of Samarinda is 48 km (30 mi) from the strait, along the Mahakam.

Wolfpack (naval Tactic)
The wolfpack was a convoy attack tactic employed in the Second World War. It was used principally by the U-boats of the during the Battle of the Atlantic, and by the submarines of the United States Navy in the Pacific War. The idea of a co-ordinated submarine attack on convoys had been proposed during the First World War but had had no success. In the Atlantic during the Second World War, the Germans had considerable successes with their wolfpack attacks but were ultimately defeated by the Allies. In the Pacific, the American submarine force was able to devastate Japan’s merchant marine, though this was not solely due to the wolfpack tactic. Wolfpacks fell out of use during the Cold War as the role of the submarine changed and as convoys became rare. World War I During the (German war on trade) Allies of World War I, Allied ships travelled independently prior to the introduction of the convoy system and were vulnerable to attacks by U-boats operating as 'lone wolves'.

Deck Gun
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret. The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute. Some submarines also had additional deck guns like auto-cannons and machine guns for anti-aircraft defense. While similar unenclosed guns are often found on surface warships as secondary or defensive armament (such as the US Navy's 5-inch (127 mm)/25 caliber gun which was removed from battleships to mount on submarines), the term "deck gun" normally re ...

5"/25 Caliber Gun
The 5"/25 caliber gun (spoken "five-inch-twenty-five-caliber") entered service as the standard heavy anti-aircraft (AA) gun for United States Washington Naval Treaty cruisers commissioned in the 1920s and 1930s. The goal of the 5"/25 design was to produce a heavy AA gun that was light enough to be rapidly trained manually. The gun was also mounted on pre-World War II battleships and aircraft carriers until replaced by the standard widespread dual-purpose 5"/38 caliber gun, which was derived from the 5"/25. Guns removed from battleships were probably converted for submarine use by late 1943, while a purpose-built variant for submarines was available in mid-1944, and was widely used by them.Campbell 1985 p.137 United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 25 calibers long (that is, for a 5" bore and a barrel length of 25 calibers, 5" x 25 = 125", or about 3.2 meters).Fairfield 1921 p.156 It is r ...

Batag Island Lighthouse
Batag Island Lighthouse is a historic lighthouse on Batag Island off the coast of the town of Laoang in the province of Northern Samar in the Philippines. The light marks the northeastern point of Samar Island and led international ships to the entrance of the San Bernardino Strait marked by the San Bernardino Light. One of the most traveled waterways in the archipelago, together with the Capul Island Light, these stations are invaluable to vessels coming from the Pacific Ocean and entering the country through the San Bernardino Strait on its way to Manila or any other ports of the Philippines. After Maniguin Island and Cape Bolinao Lighthouse, this is the third major lighthouse wholly designed and built by the Americans in the early part of American Colonial Period in the Philippines. It was the exact duplicate of the Cape Bolinao lighthouse when it was completed, both standing at 101 ft (30.8m) and both equipped with third-order lights.K.S. Heck, A.S.C.E. "Port Works ...
