A dry dock is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft.
The Long Beach Naval Shipyard, which closed in 1997, was located on Terminal Island between the city of Long Beach and the San Pedro district of Los Angeles, approximately 23 miles south of the Los Angeles International Airport. The primary role of NSY Long Beach at the time of its closure was overhaul and maintenance of conventionally-powered US Navy surface ships, but it also had served as the homeport for several auxiliary ships during its operating history.

The Federal Shipbuilding and Drydock Company was a United States shipyard in New Jersey active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board. Unlike many shipyards, it remained active during the shipbuilding slump of the 1920s and early 1930s that followed the World War I boom years. During World War II, it built merchant ships as part of the U.S. Government's Emergency Shipbuilding program, at the same time producing more destroyers for the United States Navy than any yard other than the Bath Iron Works. Operated by a subsidiary of the United States Steel Corporation, the shipyard was located at Kearny Point where the mouth of the Hackensack River meets Newark Bay in the Port of New York and New Jersey.
Burrard Dry Dock Ltd. was a Canadian shipbuilding company headquartered in North Vancouver, British Columbia. Together with neighbouring North Van Ship Repair and Yarrows Ltd. of Esquimalt, which were both later purchased by the company, Burrard built and refitted over 450 ships, including many warships for the Royal Navy and Royal Canadian Navy during the First and Second World Wars.
A Service Squadron (ServRon) was a United States Navy squadron that supported fleet combat ships and US Navy Auxiliary ships. Service Squadrons were used by the US Navy from their inception in 1943 to as late as the early 1980s. At the time of their inception during the Second World War they allowed the US Navy to operate across the vast reaches of the Pacific Ocean for extended periods of time. Service Squadrons created temporary forward bases to allow the naval squadrons to spend less time in transit and more time in the area of combat. Ulithi, a small volcanic atoll in the central Pacific, is an example of a site converted for use as a forward base of supply. Service Squadrons essentially created a major naval base near the area of operation. With naval bases like, Naval Base Ulithi, to refit, repair and resupply, many ships were able to deploy and operate in the western Pacific for a year or more without returning to a major port facility. Among the vessels operating in service squadrons were tankers, Fleet oilers, refrigerator ships, ammunition ships, supply ships, floating docks and repair ships. They provided diesel, ordnance, aviation fuel, food stuffs and all other supplies. Equally important at places like Ulithi were the portable piers and floating dry docks which allowed many ships damaged by enemy action or Pacific storms to undergo repair without having to travel the thousands of miles back to a major US naval base. Ulithi was as far forward from the US naval base at San Francisco as the San Francisco base was from London, England. To have a fully functional major port in the middle of the Pacific was a significant aid to U.S. Navy operations.
Port Weller Dry Docks was a shipbuilder on the Welland Canal at the Lake Ontario entrance. The shipbuilder was founded in 1946 and the site was initially owned by the Government of Canada for storage purchases. The shipyard expanded to include ship repair, and reconstruction work. In 1956, the drydock was sold to the Upper Lakes Shipping Company, which began the construction of vessels at the site. The shipyard twice went insolvent, most recently in 2015. Port Weller Dry Docks was used to build, refit and repair cargo vessels.

An auxiliary floating drydock is a type of US Navy auxiliary floating dry dock. Floating dry docks are able to submerge underwater and to be placed under a ship in need of repair below the water line. Water is then pumped out of the floating dry dock, raising the ship out of the water. The ship becomes blocked on the deck of the floating dry dock for repair. Most floating dry docks have no engine and are towed by tugboats to their destinations. Floating dry docks come in different sizes to accommodate varying ship sizes, while large floating dry docks come in sections and can be combined to increase their size and lift power. Ballast pontoon tanks are flooded with water to submerge or pumped dry to raise the ship.
