The Victory ship was a class of cargo ship produced in large numbers by American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship, were slightly larger and had more powerful steam turbine engines, giving higher speed to allow participation in high-speed convoys and make them more difficult targets for German U-boats. A total of 531 Victory ships were built in between 1944 and 1946.
Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output.
Port Chicago was a town on the southern banks of Suisun Bay, in Contra Costa County, California. It was located 6.5 miles (10 km) east-northeast of Martinez, at an elevation of 13 feet. It is best known as the site of a devastating explosion at its Naval Munitions Depot during World War II.
The Port Chicago disaster was a deadly munitions explosion of the ship SS E. A. Bryan on July 17, 1944, at the Port Chicago Naval Magazine in Port Chicago, California, United States. Munitions being loaded onto a cargo vessel bound for the Pacific Theater of Operations detonated, killing 320 sailors and civilians and injuring at least 390 others.
USS Mount Hood (AE-11) was the lead ship of her class of ammunition ships for the United States Navy in World War II. She was the first ship named after Mount Hood, a volcano in the Cascade Range in the US state of Oregon. On 10 November 1944, shortly after 18 men had departed for shore leave, the rest of the crew were killed when the ship exploded in Seeadler Harbor at Manus Island in Papua New Guinea. The ship was obliterated while also sinking or severely damaging 22 smaller craft nearby.
The T2 tanker, or T2, was a class of oil tanker constructed and produced in large numbers in the United States during World War II. Only the T3 tankers were larger "navy oilers" of the period. Some 533 T2s were built between 1940 and the end of 1945. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps. This occurred after two T2s, Pendleton and Fort Mercer, split in two off Cape Cod within hours of each other. Pendleton's sinking is memorialized in the 2016 film The Finest Hours. Engineering inquiries into the problem suggested the cause was poor welding techniques. It was found the steel was not well suited for the new wartime welding construction. The high sulfur content made the steel brittle and prone to metal fatigue at lower temperatures.
There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
USS Serpens (AK-97) was a Crater-class cargo ship commissioned by the United States Navy for service in World War II. She was the first ship of the US Navy to have this name: she is named after Serpens, a constellation in the northern hemisphere. Serpens was crewed by United States Coast Guard personnel and was responsible for delivering troops, goods and equipment to locations in the Asiatic-Pacific Theater.
The Port Chicago Naval Magazine National Memorial is a memorial dedicated in 1994 recognizing the dead of the Port Chicago disaster, and the critical role played by Port Chicago, California during World War II, in serving as the main facility for the Pacific Theater of Operations. The national memorial is located at the Concord Naval Weapons Station near Concord, California, in the United States.
USS Triana (IX-223), an unclassified miscellaneous vessel, was the second ship of the United States Navy to be named for Rodrigo de Triana, the discoverer of the Americas.
Roe Island Lighthouse was a lighthouse on Roe Island on the east end of Suisun Bay, California.
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.
Seatrain Lines, officially the Over-Seas Shipping Company, was a shipping and transportation company conducting operations in the Americas and trans-Pacific regions. Seatrain Lines began intermodal freight transport in December 1928 by transporting entire loaded railroad freight cars between the United States and Cuba. The specially designed ship Seatrain, built in England, was followed in 1932 by two larger ships built in the United States and in 1939 by two additional ships. By the outbreak of World War II the company was operating five ships that became important in the war effort and basis for the design of fifty new ships for military use. A series of business setbacks amid the rise of containerized shipping left the company in perilous financial condition in the 1970s. Seatrain Lines shut down in 1981 after filing for bankruptcy.
The SS China Victory was a Victory ship built during World War II under the Emergency Shipbuilding program. She was launched by the California Shipbuilding Company on January 26, 1944, and completed on April 1, 1944. The ship's United States Maritime Commission designation was 'VC2- S- AP3, hull number 1'. She was operated by the Matson Navigation Company of Hawaii. SS China Victory served in the Pacific Ocean during World War II. The 10,500-ton Victory ships were designed to replace the earlier Liberty Ships. Liberty ships were designed to be used just for World War II compared to Victory ships, which were designed to last longer and serve the US Navy after the war. Victory ships differed from Liberty ships in that they were faster, longer and wider, taller, had a thinner stack set farther toward the superstructure, and had a long raised forecastle.
SS Hobbs Victory was a cargo Victory ship built for World War II under the Emergency Shipbuilding program. Hobbs Victory, was launched on January 9, 1945 by Permanente Metals Corporation, Richmond, California and completed on January 9, 1945. She was built in just 87 days. She was operated by the Sudden & Christenson for the United States Maritime Commission.
The SS Joplin Victory was the 12th Victory ship built during World War II under the Emergency Shipbuilding program. She was launched by the California Shipbuilding Company on April 25, 1944 and completed on June 15, 1944. The ship's United States Maritime Commission designation was VC2-S-AP3, hull number 12 (V-12). The 10,500-ton Victory ships were designed to replace the earlier Liberty Ships. Liberty ships were designed to be used just for World War II. Victory ships were designed to last longer and serve the US Navy after the war. The Victory ship differed from a Liberty ship in that they were: faster, longer and wider, taller, had a thinner stack set farther toward the superstructure and had a long raised forecastle.
The SS Drexel Victory was a Victory-class cargo ship built during World War II. The SS Drexel Victory (MCV-712), was a type VC2-S-AP2 victory ship built by Permanente Metals Corporation, Yard 2, of Richmond, California under the Emergency Shipbuilding program. The Maritime Administration cargo ship was the 744th victory ship. Her keel was laid on February 25, 1945. The ship was christened on May 2, 1945. The ship was named in honor of Drexel University in Philadelphia, one of 150 educational institutions that had Victory ships named after them.
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.
SS Samuel Heintzelman was a Liberty ship built in the United States during World War II. Named after Samuel Heintzelman, a United States Army general, the ship was laid down by California Shipbuilding Corporation at Terminal Island in Los Angeles, and launched on 27 August 1942. It was operated by Coastwise Line.
