The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slower type of aircraft carrier used by the Royal Navy, the Royal Canadian Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
The fast combat support ship is a type of replenishment auxiliary ship. Different from traditional logistic ships, the fast combat support ship is designed with high speed to keep up with the carrier battle group/carrier strike group, while the multi-product station is capable of supplying all types of necessities for the fleet.
Seeadler Harbor, also known as Port Seeadler, is located on Manus Island, Admiralty Islands, Papua New Guinea and played an important role in World War II. In German, "Seeadler" means sea eagle, pointing to German colonial activity between 1884 and 1919 in that area. The bay was named in 1900 after the German cruiser SMS Seeadler.
A reefer ship is a refrigerated cargo ship typically used to transport perishable cargo, which require temperature-controlled handling, such as fruits, meat, vegetables, dairy products, and similar items.
Naval Station Norfolk is a United States Navy base in Norfolk, Virginia, that is the headquarters and home port of the U.S. Navy's Fleet Forces Command. The installation occupies about 4 miles (6.4 km) of waterfront space and 11 miles (18 km) of pier and wharf space of the Hampton Roads peninsula known as Sewell's Point. It is the world's largest naval station, with the largest concentration of U.S. Navy forces through 75 ships alongside 14 piers and with 134 aircraft and 11 aircraft hangars at the adjacently operated Chambers Field. Port Services controls more than 3,100 ships' movements annually as they arrive and depart their berths.
Concrete ships are built primarily with ferrocement hulls, reinforced with steel bars. This contrasts against more traditional materials, such as pure steel or wood. The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. During the late 19th century, there were concrete river barges in Europe, and during both World War I and World War II, steel shortages led the US military to order the construction of small fleets of ocean-going concrete ships, the largest of which was the SS Selma. United States Maritime Administration (MARAD) designation for concrete ships-barges was Type B ship. Few concrete ships were completed in time to see wartime service during World War I, but during 1944 and 1945, concrete ships and barges were used to support U.S. and British invasions in Europe and the Pacific. Since the late 1930s, there have also been ferrocement pleasure boats.
Naval Base San Diego is a United States Navy base in San Diego, California. It is the world's second largest surface ship naval base. Naval Base San Diego is the principal homeport of the United States Pacific Fleet, consisting of over 50 ships and over 150 tenant commands. The base is composed of 13 piers stretched over 1,600 acres (650 ha) of land and 326 acres (132 ha) of water. The total on base population is over 24,000 military personnel and over 10,000 civilians.
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.
A barracks ship or barracks barge or berthing barge, or in civilian use accommodation vessel or accommodation ship, is a ship or a non-self-propelled barge containing a superstructure of a type suitable for use as a temporary barracks for sailors or other military personnel. A barracks ship, a military form of a dormitory ship, may also be used as a receiving unit for sailors who need temporary residence prior to being assigned to their ship. The United States Navy used to call them Yard Repair Berthing and Messing with designations YRBM and YRBM(L) and now classes them as either Auxiliary Personnel Barracks (APB) or Auxiliary Personnel Lighter (aka barge) (APL).
USNS Navajo (T-ATF-169) was a United States Navy Powhatan-class tugboat operated by the Military Sealift Command which was in service from 1980 to 2016. She spent the bulk of her career in the Pacific and is currently moored in Pearl Harbor, awaiting disposal.
USNS Sioux (T-ATF-171) was a United States Navy Powhatan-class tugboat operated by the Military Sealift Command (MSC). She was in service from 1981 to 2021 and spent the bulk of this time supporting the Pacific Fleet.
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 chemical elements.
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.
USS AFDM-2,, is an AFDM-3-class medium auxiliary floating drydock built in Mobile, Alabama by the Alabama Drydock and Shipbuilding Company for the U.S. Navy. Originally named USS YFD-4, Yard Floating Dock-4, she operated by Todd Shipyards at New Orleans, Louisiana for the repair of US ships during World War II. YFD-4 was renamed an Auxiliary Floating Dock Medium AFDM-2 in 1945 after the war.
USS ABSD-2, later redesignated as AFDB-2, was a ten-section, non-self-propelled, large auxiliary floating drydock of the US Navy. Advance Base Sectional Dock-2 was constructed in sections during 1942 and 1943 by the Mare Island Naval Shipyard in Vallejo, California for World War II. Her official commissioning ceremony took place on 14 August 1943 with CDR Joseph J. Rochefort in command. With all ten sections joined, she was 927 feet (283 m) long, 28 feet (8.5 m) tall, and with an inside clear width of 133 feet 7 inches (40.72 m). ABSD-2 had a traveling 15-ton capacity crane with an 85-foot (26 m) radius and two or more support barges. The two side walls were folded down under tow to reduce wind resistance and lower the center of gravity. ABSD-2 had 6 capstans for pulling, each rated at 24,000 lbf (110,000 N) at 30 ft/min (0.15 m/s), 4 of the capstans were reversible. There were also 12 ballast compartments in each section.
ABSD-6 is an advanced base sectional dock which was constructed of nine advance base docks (ABD) sections for the US Navy as an auxiliary floating drydock for World War II. ABSD-6 was built by Mare Island Naval Shipyard at Vallejo, California. ABSD-6 was commissioned on 28 September 1944. Advance Base Sectional Dock-6 was constructed in sections during 1942 and 1943. Each section are 3,850 tons and are 93 feet long each. Each Section had a 165 feet beam, a 75 feet molded depth and had 10,000 tons lifting capacity each. There were 4 ballast compartments in each section. With all nine sections joined, she was 825 feet long, 28 feet tall, and with an inside clear width of 133 feet 7 inches. ABSD-2 had a traveling 15-ton capacity crane with an 85-foot radius and two or more support barges. The two side walls were folded down under tow to reduce wind resistance and lower the center of gravity. ABSD-6 had 6 capstans for pulling, each rated at 24,000 lbf (110,000 N) at 30 ft/min (0.15 m/s), 4 of the capstans were reversible.
Everett-Pacific Shipbuilding & Dry Dock Company was established in 1942 to build ships needed for World War II. Yard construction began on 1 March 1942. As part of the Emergency Shipbuilding Program, the US Navy provided some of the capital to start Everett-Pacific Shipbuilding at Port Gardner Bay in Everett, Washington. Everett-Pacific was sold in 1945 to the Pacific Car and Foundry, who was already a major manufacturer of railcars and trucks. Pacific Car and Foundry was building barges for the US Navy during World War II at plants in Renton, Seattle and Tacoma in the state of Washington. The lease for the shipyard in Everett, Washington ended in 1949 and the yard closed. Pacific Car and Foundry in 1972 changed its name to Paccar Inc. to reflect its major products. The Everett-Pacific shipyard site later became part of Western Gear, a heavy machinery manufacturer. From 1987 to 1992, the shipyard was rebuilt to become part of Naval Station Everett. Everett-Pacific Shipbuilding was started by William Pigott Jr. a Seattle businessmen and his brother Paul Pigott (1900-1961). William Pigott Jr. was born in 26 Aug. 1895 in Pueblo, CO and died on 8 July 1947 in San Francisco, CA.
Pollock-Stockton Shipbuilding Company was established in 1942 to build ships needed for World War II. As part of the Emergency Shipbuilding Program the US Navy provided some of the capital to start Pollock-Stockton Shipbuilding at Stockton, California. The shipyard was located at San Joaquin River and Stockton Channel, near Louis Park. After the war the shipyard closed down in February 1946.
Naval Base Eniwetok was a major United States Navy base located at Enewetak Atoll in the Marshall Islands, during World War II. The base was built to support the island-hopping strategy used by allied nations fighting the Empire of Japan in the Pacific War. During 1944-5 Eniwetok was one of the busiest naval bases in the world with over 488 ships.
