The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
Avondale Shipyard was an independent shipbuilding company, acquired by Litton Industries, in turn acquired by Northrop Grumman Corporation. In 2011, along with the former Ingalls Shipbuilding, the yard was part of Huntington Ingalls Industries. It closed in October 2014. The yard was located on the west bank of the Mississippi River in an area called Bridge City, about 20 miles (32 km) upriver from New Orleans near Westwego, Louisiana. It was the site of the modernization of the battleship USS Iowa in the early 1980s and also constructed some of the lighter aboard ships (LASH). At one time, it was the largest employer in Louisiana, with about 26,000 employees.
Lake freighters, or lakers, are bulk carrier vessels that operate on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships.
USS Carpellotti (APD-136) was a Crosley-class high speed transport in service with the United States Navy from 1945 to 1958. She was sold for scrap in 1966. Carpellotti was named after Marine Private First Class Louis J. Carpellotti (1918–1942), who was posthumously awarded the Silver Star for his actions on Tulagi, Solomon Islands, during the Battle of Guadalcanal.
The USCGC Escanaba (WPG-77) was a 165 ft (50 m) "A" type United States Coast Guard cutter stationed on the Great Lakes from her commissioning in 1932 until the start of U.S. military involvement in World War II in 1941. With the outbreak of war, Escanaba redeployed to participate in the Battle of the Atlantic, during the course of which she was ultimately lost with nearly all hands. Struck by either a torpedo or mine in the early morning of 13 June 1943, while serving as a convoy escort, Escanaba suffered a fiery explosion and sank within minutes, leaving only two survivors and one body out of her 105-man crew to be found on the surface by rescuers.
The 3"/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes.
USS PC-1129 was a PC-461-class submarine chaser built for the United States Navy during World War II. She was sunk by a Japanese suicide boat in January 1945 in the South China Sea.
Bay Shipbuilding Company (BSC) is a shipyard and dry dock company in Sturgeon Bay, Door County, Wisconsin. As of 2015, Bay Ships was a subsidiary of Fincantieri Marine Group and produces articulated tug and barges, OPA-90 compliant double hull tank ships and offshore support vessels. It also provides repair services to the lake freighter fleet. In the past the shipyard located in Sturgeon Bay has operated under several different names and traces its history back to 1918.
The Type B ship is a United States Maritime Administration (MARAD) designation for World War II barges. Barges are very low cost to build, operate and move. Barges were needed to move large bulky cargo. A tug boat, some classed as Type V ships, could move a barge, then depart and move on to the next task. That meant the barge did not have to be rushed to be unloaded or loaded. Toward the end of World War 2, some ships that had not been completed in time for the war were converted to barges. US Navy barges are given the prefix: YWN or YW. Due to shortage of steel during World War II, concrete ship constructors were given contracts to build concrete barges, with ferrocement and given the prefix YO, YOG, YOGN. Built in 1944 and 1945, some were named after elements.
The following index is provided as an overview of and topical guide to Wikipedia's articles on recreational dive sites. The level of coverage may vary:
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
The United States Coast Guard wooden-hulled 75-foot patrol boats were built during Prohibition to help interdict alcohol smugglers. Their nickname was derived from the slang term "six bits" meaning 75 U.S. cents.
Splinter fleet or Splinter navy was a nickname given to the United States wooden boats used in World War II. The boats served in many different roles during the war. These boats were built in small boatyards on the West coast and East coast, Great Lakes and the Gulf of Mexico. They could be built quickly, in just 60 to 120 days. Most of the boats were built by boatyards that already had the tools and knowledge from building yachts, sailboats and motor boats. Many were built by craftsmen in family-owned small businesses. Under the Emergency Shipbuilding Program and War Shipping Administration contracts went out to over fifty boatyards across the country. The boats were built for the US Navy, the United States Army Air Forces, United States Coast Guard, and US Army. Some of the wooden boats went to Allied nations on the Lend-Lease program.
US Navy Small Craft Training Centers(SCTC) were United States Navy training bases used to train sailors in the operation of the many small wooden crafts used in World War II. These crafts were given the nickname Splinter Fleet. There was a shortage of steel and steel shipyards during World War II, so there was a need for a vast wooden fleet of crafts. The Small Craft Training Centers had classrooms and crafts for training. The bases had barrack housing and mess halls. To get the men and crafts out into the field quickly, at many of the bases men trained on new ships. The new ships were at the center for about 4 weeks as part of the vessel's sea trial. Tugboats, Minesweepers, Net laying ships, Crash boats, PT boats and other crafts built near the center were taken to the Small Craft Training Centers for testing. Crafts built at Lynch Shipbuilding in San Diego, California were taken to the Small Craft Training Center at Terminal Island, San Pedro, California for their sea trial. Lynch Shipbuilding built tugboats, and minesweepers. Some of the craft at the Terminal Island school were: USS Density (AM-218), USS Waxsaw (AN-91), and USS Climax (AM-161), USS Wateree (ATF-117), USS Quest (AM-281), USS Snowbell (AN-52). The US Navy also had Small Craft Training Centers in Miami, Florida, Santa Barbara, California, New Orleans, Louisiana and other sites.
