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.
The Tacoma class was a class of 96 patrol frigates which served in the United States Navy during World War II and the Korean War. Originally classified as gunboats (PG), they were reclassified as patrol frigates (PF) on 15 April 1943. The class is named for its lead ship, Tacoma, a Maritime Commission (MARCOM) S2-S2-AQ1 design, which in turn was named for the city of Tacoma, Washington. Twenty-one ships were transferred to the British Royal Navy, in which they were known as Colony-class frigates, and twenty-eight ships were transferred under Lend-Lease to the Soviet Navy, where they were designated as storozhevoi korabl, during World War II. All Tacoma-class ships in US service during World War II were manned by United States Coast Guard crews. Tacoma-class ships were transferred to the United States Coast Guard and various navies post-World War II.
Lake freighters, or lakers, are bulk carrier vessels operating on the Great Lakes of North America. These vessels are traditionally called boats, although classified as ships. Freighters typically have a long, narrow hull, a raised pilothouse, and the engine located at the rear of the ship.
The Rudderow-class destroyer escorts were destroyer escorts launched in the United States in 1943 to 1945. Of this class, 22 were completed as destroyer escorts, and 50 were completed as Crosley-class high speed transports and were re-classified as high speed transport APDs. One ship was converted to an APD after completion. They served in World War II as convoy escorts and anti-submarine warfare ships.
USCGC Onondaga (WPG-79), a United States Coast Guard cutter, was built by Defoe Boat Works in Bay City, Michigan, commissioned on 11 September 1934. From its commissioning until 1941, Onondaga was stationed at Astoria, Oregon, where she performed important law enforcement duties and rendered much assistance to ships in distress. Each year she patrolled the annual pelagic seal migration to the Pribilof Islands, and she attempted to prevent out of season halibut fishing.
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.
USS Menemsha (AG-39) was a cargo ship acquired by the U.S. Navy during World War II. She was used as a weather-gathering ship, a patrol craft and convoy escort vessel in the North Atlantic Ocean. Although a Navy ship, she was operated by the U.S. Coast Guard, and eventually was transferred to that agency as USCGC Menemsha (WAG-274).
The second USS Willoughby (AGP-9) was a motor torpedo boat tender that served in the United States Navy from 1944 to 1946, seeing service in the later stages of World War II. Transferred to the United States Coast Guard in 1946, she was in commission as the cutter USCGC Gresham (WAVP-387), later WHEC-387 and WAGW-387, from 1947 to 1969 and from 1970 to 1973, seeing service in the Vietnam War during her Coast Guard career.
The American Ship Building Company was the dominant shipbuilder on the Great Lakes before the Second World War. It started as Cleveland Shipbuilding in Cleveland, Ohio in 1888 and opened the yard in Lorain, Ohio in 1898. It changed its name to the American Ship Building Company in 1900, when it acquired Superior Shipbuilding, in Superior, Wisconsin; Toledo Shipbuilding, in Toledo, Ohio; and West Bay Shipbuilding, in West Bay City, Michigan. With the coming of World War I, the company also acquired Buffalo Dry Dock, in Buffalo, New York; Chicago Shipbuilding, in Chicago, Illinois; and Detroit Shipbuilding, in Wyandotte, Michigan. American Shipbuilding ranked 81st among United States corporations in the value of World War II military production contracts.

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.
Victory Shipbuilding was the name of two shipbuilding companies that built vessels during World War 2. The first was the Victory Shipbuilding Company, of Holland, Michigan, and the second was the Victory Shipbuilding Corporation, of Newport Beach, California.
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.
