USS Remora
USS ''Remora'' (SS-487), a , was the only ship of the United States Navy to be named for the remora, a fish with a suctorial disk on its head enabling it to cling to other fish and to ships. Construction and commissioning ''Remora''′s keel was laid down on 5 March 1945 by the Portsmouth Navy Yard in Kittery, Maine. She was launched on 12 July 1945, sponsored by Mrs. T. W. Samuels III, and commissioned on 3 January 1946 with Commander Robert Sellars in command. Service history Training submarine Completing her Caribbean Sea shakedown in April 1946, ''Remora'' operated out of New London, Connecticut, as a training submarine until January 1947. Then transferred to the Pacific, she transited the Panama Canal at mid-month and arrived at Mare Island, Vallejo, California, on 14 February to begin a Greater Underwater Propulsive Power Program (GUPPY-II) conversion. Early in November, she completed trials and on 22 February arrived at San Diego, California, her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Underwater Propulsive Power Program
The Greater Underwater Propulsion Power Program (GUPPY) was initiated by the United States Navy after World War II to improve the submerged speed, maneuverability, and endurance of its submarines. (The "Y" in the acronym was added for pronounceability.) The navy began the program by testing and reverse engineering two German Type XXI U-boats— and —obtained as war reparation. That analysis led to four goals—increasing the submarines' battery capacity, streamlining the boats' structures, adding snorkels, and improving fire control systems. The navy immediately focused on designing a new class of submarine, but the Bureau of Ships believed the fleet of existing , , and submarines could be modified to incorporate the desired improvements. In June 1946, the Chief of Naval Operations approved the GUPPY project. The initial two-boat test program, implemented by the Portsmouth Naval Shipyard, eventually grew into several successive conversion programs. Those upgrades proceeded i ...

BQG-4
Passive Underwater Fire Control Feasibility System (or Study) (PUFFS) was a passive sonar system for submarines. It was designated AN/BQG-4 and was primarily installed on United States Navy conventional submarines built in the 1950s beginning with the , and also those converted to GUPPY III or otherwise modernized in the 1960s. It was also equipped on the nuclear-powered . It was also installed on the USS Thomas Edison (SSBN610) but never achieved operational status. Its transducers can be seen on pictures of the vessel. A version known as "Micropuffs" was fitted on s for the Royal Australian Navy, and as Type 2041 on the ''Upholder''-class for the British Royal Navy. This class still serves in the Royal Canadian Navy as the ''Victoria'' class, where Micropuffs is known as BQG-501. The system was notable for three tall, fin-like domes topside, except on Micropuffs installations. The system was retained on several submarines transferred by the US to foreign navies. It was associated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallejo, California
Vallejo ( ; ) is a city in Solano County, California and the second largest city in the North Bay region of the Bay Area. Located on the shores of San Pablo Bay, the city had a population of 126,090 at the 2020 census. Vallejo is home to the California Maritime Academy, Touro University California and Six Flags Discovery Kingdom. Vallejo is named after Mariano Guadalupe Vallejo, the famed Californio general and statesman. The city was founded in 1851 on General Vallejo's Rancho Suscol to serve as the capital city of California, which it served as from 1852 to 1853, when the Californian government moved to neighboring Benicia, named in honor of General Vallejo's wife Benicia Carrillo de Vallejo. The following year in 1854, authorities founded the Mare Island Naval Shipyard, which defined Vallejo's economy until the turn of the 21st century. History Vallejo was once home of the Coastal Miwok as well as Suisunes and other Patwin Native American tribes. There are three co ...

Mare Island
Mare Island (Spanish: ''Isla de la Yegua'') is a peninsula in the United States in the city of Vallejo, California, about northeast of San Francisco. The Napa River forms its eastern side as it enters the Carquinez Strait juncture with the east side of San Pablo Bay. Mare Island is considered a peninsula because no full body of water separates this or several other named "islands" from the mainland. Instead, a series of small sloughs cause seasonal water-flows among the so-called islands. Mare Island is the largest of these at about long and a mile wide. History In 1775, Spanish explorer Perez Ayala was the first European to land on what would become Mare Island – he named it ''Isla de la Plana''. This area was part of Rancho Suscol, deeded to General Mariano Guadalupe Vallejo in 1844. It became a waypoint for early settlers. In 1835, whilst traversing the Carquinez Strait, a crude ferry transporting men and livestock capsized in a squall. Among the livestock feared lost ...

Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the ...

New London, Connecticut
New London is a seaport city and a port of entry on the northeast coast of the United States, located at the mouth of the Thames River in New London County, Connecticut. It was one of the world's three busiest whaling ports for several decades beginning in the early 19th century, along with Nantucket and New Bedford, Massachusetts. The wealth that whaling brought into the city furnished the capital to fund much of the city's present architecture. The city subsequently became home to other shipping and manufacturing industries, but it has gradually lost most of its industrial heart. New London is home to the United States Coast Guard Academy, Connecticut College, Mitchell College, and The Williams School. The Coast Guard Station New London and New London Harbor is home port to the Coast Guard Cutter ''Coho'' and the Coast Guard's tall ship ''Eagle''. The city had a population of 27,367 at the 2020 census. The Norwich–New London metropolitan area includes 21 towns and 274,055 ...

Commander (United States)
In the United States, commander is a military rank that is also sometimes used as a military billet title—the designation of someone who manages living quarters or a base—depending on the branch of service. It is also used as a rank or title in non-military organizations; particularly in law enforcement. As rank History The commander rank started out as "Master and Commander" in 1674 within the Royal Navy for the officer responsible for sailing a ship under the Captain and sometimes second-in-command. Sub-captain, under-captain, rector and master-commanding were also used for the same position. With the Master and Commander also serving as captain of smaller ships the Royal Navy subsumed as the third and lowest of three grades of captain given the various sizes of ships. The Continental Navy had the tri-graded captain ranks. Captain 2nd Grade, or Master Commandant, became Commander in 1838.

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Portsmouth Navy Yard
The Portsmouth Naval Shipyard, often called the Portsmouth Navy Yard, is a United States Navy shipyard in Kittery on the southern boundary of Maine near the city of Portsmouth, New Hampshire. Founded in 1800, PNS is U.S. Navy's oldest continuously operating shipyard. Today, most of its work concerns the overhaul, repair, and modernization of submarines. As of November 2021, the shipyard employed more than 6,500 federal employees. As well, some of the work is performed by private corporations (e.g., Delphinius Engineering of Eddystone, Pennsylvania; Oceaneering International of Chesapeake, Virginia; Orbis Sibro of Mount Pleasant, South Carolina; and Q.E.D. Systems Inc. of Virginia Beach, Virginia). History The Portsmouth Naval Shipyard was established on June 12, 1800, during the administration of President John Adams. It sits on a cluster of conjoined islands called Seavey's Island in the Piscataqua River, whose swift tidal current prevents ice from blocking navigation to t ...

Keel-laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
