USS ''S-37'' (SS-142) was an ''S''-class submarine of the United States Navy. Construction and commissioning ''S-37''′s keel was laid down on 12 December 1918 by the Union Iron Works in San Francisco, California.DANFS. She was launched on 20 June 1919, sponsored by Miss Mildred Bulger, and commissioned on 16 July 1923. Operational service 1923 After fitting out at Mare Island, ''S-37'' departed San Francisco Bay at the end of July 1923 and joined Submarine Division (SubDiv) 17 at San Pedro, California, on 1 August 1923. During August, September, and into October 1923, she conducted exercises and tests off the Southern California coast. On the afternoon of 10 October 1923, while recharging her batteries in the harbor at San Pedro, ''S-37'' was rocked by an explosion in the after battery compartment. Two men were killed as dense black smoke and gas fumes filled the flame- and arc-lit room. Extensive material damage added to the difficulty of rescue operations, but three ...

Union Iron Works
Union Iron Works, located in San Francisco, California, on the southeast waterfront, was a central business within the large industrial zone of Potrero Point, for four decades at the end of the nineteenth and beginning of the twentieth centuries. History Peter Donohue, an Irish immigrant, founded Union Brass & Iron Works in the south of Market area of San Francisco in 1849. It was later run by his son, James Donohue. After years as the premiere producer of mining, railroad, agricultural and locomotive machinery in California, Union Iron Works, led by I. M. Scott, entered the ship building business and relocated to Potrero Point where its shipyards still exist, making the site on the north side of the Potrero the longest running privately owned shipyard in the United States. After Bethlehem Shipbuilding Corporation bought the works in 1905, the consolidated company came to include the Alameda Works Shipyard, located across the San Francisco Bay in Alameda and the Hunter's Poin ...

Fleet Problem III
The Fleet Problems are a series of naval exercises of the United States Navy conducted in the interwar period, and later resurrected by Pacific Fleet around 2014. The first twenty-one Fleet Problems — labeled with roman numerals as Fleet Problem I through Fleet Problem XXI — were conducted between 1923 and 1940. They were usually once-a-year exercises in which U.S. naval forces would engage in mock battles. One or more of the forces would play the part of a European or Asian navy. They were the culmination of the Navy's annual training maneuvers. Fleet Problem XXII, scheduled for 1941, was canceled because of the rising tensions with Japan that led to the US' entry into World War II. Following the outbreak of war, Fleet Problems underwent a prolonged hiatus, with other names being used to describe large American naval exercises. However, the term was revived in the 21st century under Admiral Scott H. Swift, with Fleet Problem XXIII through XXVIII taking place in the Pacific ...

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 fear ...

Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats ...

Electric Battery
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell. Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery use ...

San Pedro, California
San Pedro ( ; Spanish: "St. Peter") is a neighborhood within the City of Los Angeles, California. Formerly a separate city, it consolidated with Los Angeles in 1909. The Port of Los Angeles, a major international seaport, is partially located within San Pedro. The district has grown from being dominated by the fishing industry, to a working-class community within the city of Los Angeles, to a rapidly gentrifying community. History The peninsula, including all of San Pedro, was the homeland of the Tongva-Gabrieleño Native American people for thousands of years. In other areas of the Los Angeles Basin archeological sites date back 8,000–15,000 years. The Tongva believe they have been here since the beginning of time. Once called the "lords of the ocean", due to their mastery of oceangoing canoes (Ti'ats), many Tongva villages covered the coastline. Their first contact with Europeans was in 1542 with Juan Rodríguez Cabrillo, the Spanish explorer who also was the first to writ ...

Division (naval)
A naval division is a subdivision of a squadron or flotilla. It can also be a subdivision of a fleet. A division is the smallest naval formation, most commonly numbering between two to four ships. Command element A division is usually commanded by senior flag officer, most commonly a vice admiral or rear admiral, irrespective of the division's size. For example, in the Imperial Japanese Navy the First Carrier Division was commanded by a rear or vice admiral, same as the 18th Cruiser Division. Division types Divisions are most commonly grouped by ship class and type, dependent on how the respective nation's navy is organised. Examples of division types include: *Submarine Division – 24th Submarine Division ( Soviet Navy and Russian Navy) – six submarines *Minesweeper Division – Mine Division 71 (United States Navy) – two minesweepers *Sloop Division – 2nd Escort Group (Royal Navy) – six sloops *Destroyer Division – Destroyer Division 22 (United States N ...

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 c ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
