Naval Operating Base Terminal Island, (NOB Terminal Island) was United States Navy base founded on 25 September 1941 to support the World War II efforts in the Pacific War. Naval Operating Base Terminal Island was founded by combining Naval Facilities in cities of San Pedro, Long Beach and Wilmington, California under one command. Much of the base was on the man-made Terminal Island, and harbor in San Pedro Bay. The harbor was made through the construction of a large breakwater system.

Terminal Island, historically known as Isla Raza de Buena Gente, is a largely artificial island located in Los Angeles County, California, between the neighborhoods of Wilmington and San Pedro in the city of Los Angeles, and the city of Long Beach. Terminal Island is roughly split between the Port of Los Angeles and Port of Long Beach. Land use on the island is entirely industrial and port-related except for Federal Correctional Institution, Terminal Island.

Naval Air Base San Pedro, NAS Terminal Island was a US Navy World War II 410-acre airfield on Terminal Island in San Pedro, California part of the City of Los Angeles. Before the Navy took control of the airfield, the airstrip was the civilian Allen Field. Allen Field was built in 1927 by filling with sand the Port of Los Angeles and enlarging Terminal Island. Terminal Island is located between San Pedro Harbor and Long Beach Harbor. Allen Field was serviced by the Pacific Electric and pedestrian ferries. The air terminal has three runways in a triangle shape, two short runways and one 4,200 foot runway. A large seaplane ramp was also built at the terminal. A Naval Air Reserve Training Facility was built next to Allen Field in 1927 and used the runway - ramp. Civilian use ended in 1935 and the site began an air base, later renamed Reeves Field San Pedro, after Rear Admiral Joseph M. Reeves. On on 25 September 1941 Naval Air Base San Pedro became part of Naval Operating Base Terminal Island. In 1942 many Reserve troops were trained at the Naval Air Base. In 1943 the Navy took over operations and the Reserve was moved to Naval Air Base Los Alamitos. The base was renamed Naval Air Station Terminal Island and continued as a training base until the end of the war in 1945. In 1942, NAB San Pedro, now NAS Terminal Island, was designated for equipping and performing flight-tests on the large number of military aircraft fabricated at nearby plants in Southern California: Lockheed, Douglas Aircraft Company and & Vultee Aircraft. To facilitate delivery of these aircraft, the U.S. Navy established the Naval Air Ferry Command (NAFC) (VRF-3) in 1943. During the war the base was commander was Captain Kneflar "Socko" McGinnis. The base was a 24/7 operation, testing and shipping out planes at a rate of approximately 200 a month. Due to a shortage to servicemen during the war, a unit of WAVES (Women Accepted for Volunteer Emergency Service) was stationed at the base. The 200 strong WAVES served as mechanics, air traffic controllers, radio operators, trainers and air navigators. After the war the base was closed in 1947 and turned over to the Bureau of Yards and Docks. The nearby Naval Air Base Long Beach continued to use the air field until 1997 at which time the base was abandoned; there is no trace of the base today.

The Vincent Thomas Bridge is a 1,500-foot-long (460 m) suspension bridge, crossing Los Angeles Harbor in Los Angeles, California, linking San Pedro with Terminal Island. It is the only suspension bridge in the Greater Los Angeles area. The bridge is part of State Route 47, which is also known as the Seaside Freeway. The bridge opened in 1963 and is named for California Assemblyman Vincent Thomas of San Pedro, who championed its construction. Its chief engineer was William (Jim) Jurkovich who was instrumental in bringing pre-stress concrete bridge design to California. It was the first welded suspension bridge in the United States and is now the fourth-longest suspension bridge in California and the 76th-longest span in the world. The clear height of the navigation channel is approximately 185 feet (56 m); it is the only suspension bridge in the world supported entirely on piles.

The Port of Los Angeles is a seaport managed by the Los Angeles Harbor Department, a unit of the City of Los Angeles. It occupies 7,500 acres (3,000 ha) of land and water with 43 miles (69 km) of waterfront and adjoins the separate Port of Long Beach. Promoted as "America's Port", the port is located in San Pedro Bay in the San Pedro and Wilmington neighborhoods of Los Angeles, approximately 20 miles (32 km) south of downtown. The cargo coming into the port represents approximately 20% of all cargo coming into the United States. The port's channel depth is 53 feet (16 m). The port has 25 cargo terminals, 82 container cranes, 8 container terminals, and 113 miles (182 km) of on-dock rail. The port's top imports were furniture, automobile parts, apparel, footwear, and electronics. In 2019, the port's top exports were wastepaper, pet and animal feed, scrap metal and soybeans. In 2020 the port's top three trading partners were China (including Hong Kong), Japan, and Vietnam. In 2022, the port, together with the adjoining Port of Long Beach, were considered amongst the world's least efficient ports by the World Bank and IHS Markit citing union protectionism and a lack of automation.

The Commodore Schuyler F. Heim Bridge was a vertical-lift bridge in the Port of Los Angeles. Dedicated on January 10, 1948, the bridge allowed State Route 47 (the Terminal Island Freeway) to cross over the Cerritos Channel. Named after Schuyler F. Heim, who was in command of the Naval Air Station on Terminal Island in 1942, the bridge was one of the largest vertical-lift bridges on the West Coast. At the time of its opening, it was the highest in the country with the deck weighing about 820 short tons (740 metric tons). Its towers are 186 feet (57 m) tall above the roadway deck and about 236 feet (72 m) tall when measured from the water level at high water. The bridge was decommissioned on October 12, 2015 and replaced by a new, six-lane fixed-span bridge in order to meet current safety and earthquake standards. A replacement bridge, tentatively titled State Route 47 Schuyler Heim Bridge Replacement, was completed in September 2020.
