Vandenberg Space Launch Complex 4

USS Charles (ID-1298) was a troop transport that served in the United States Navy from 1918 to 1920 and was briefly in commission as USS Harvard in 1918 and 1920. She was better known in her role as passenger liner SS Harvard, one of the premier West Coast steamships operated by the Los Angeles Steamship Company.

Point Arguello (Spanish: Punta Argüello) is a headland on the Gaviota Coast, in Santa Barbara County, California, near the city of Lompoc. The area was first used by the United States Navy in 1959 for the launch of military and sounding rockets. It was transferred to the United States Air Force in 1964, at which time it became part of Vandenberg Air Force Base.

Sibyl Marston was a wooden schooner cargo ship built by W. A. Boole & Son of Oakland, California and belonging to the Sibyl Marston Co. Sibyl Marston sank off the coast of Lompoc, California on 12 January 1909.

Honda was a remote and sparsely populated rural district in the vicinity of Cañada Honda Creek in Santa Barbara County, California, United States. The area produced sweet peas and beans, and supported dairy farms. A newspaper account of 1947 stated, "The Jesus Maria rancho, Packard rancho, Bear Creek ranch, Honda section, and a large area in the lower [Lompoc] valley once yielded great crops of cattle and produce and furnished a livelihood for many families." The area is now part of Vandenberg Space Force Base.

Space Launch Complex 5 (SLC-5) was a launch pad at Vandenberg Space Force Base in California, United States. It was previously part of the Point Arguello Naval Air Station, during which time it was designated Launch Complex D or LC-D. Constructed in 1961, it was used by 69 Scout launch vehicles between 1962 and 1994. Satellites launched from the complex included Transit, OV3, Explorer and P35 (DMSP) spacecraft. Most of the satellites launched from SLC-5 were placed into low Earth orbits, or low medium Earth orbits. As of 2009*, the complex is still standing, however the U.S. Air Force is considering demolishing it to salvage parts. If the complex is dismantled, there are plans to produce a Historic American Engineering Record of the site, and to preserve the tower.

USS Fuller (DD-297) was a Clemson-class destroyer built for the United States Navy during World War I.

The Honda Point disaster was the largest peacetime loss of U.S. Navy ships in U.S. history. On the evening of September 8, 1923, seven destroyers, while traveling at 20 knots (37 km/h), ran aground at Honda Point (also known as Point Pedernales; the cliffs just off-shore called Devil's Jaw), a few miles from the northern side of the Santa Barbara Channel off Point Arguello on the Gaviota Coast in Santa Barbara County, California. Two other ships grounded, but were able to maneuver free off the rocks. Twenty-three sailors died in the disaster.

The Canyon Fire was a wildfire that burned on Vandenberg Space Force Base in Santa Barbara County, California during September 2016. By the time the fire was contained on September 24, it had burned 12,742 acres (51.6 km2) of land. Due to the nature of the activities that take place on the Base, there were a number of unique challenges posed during the fire including the presence of potentially hazardous materials.

Lompoc–Surf station is a passenger rail station in Surf, California, west of the city of Lompoc. It is served by Amtrak's Pacific Surfliner from San Luis Obispo to San Diego.Lompoc–Surf station is served by four Amtrak Pacific Surfliner trains (two in each direction).In Fiscal Year 2022, 7,560 passengers boarded or detrained at Lompoc–Surf station.The station opened for service on March 18, 2000. Pre-Amtrak, a Southern Pacific Railroad station was located at Surf. Passenger service ended by 1971, but a telegraph office remained in use until 1985.

Surf is an unincorporated area of Santa Barbara County, California, located along the Pacific coast within a publicly accessible area of Vandenberg Space Force Base west of the city of Lompoc. The site originally was established as a railroad town, with its growth peaking after Vandenberg was established in 1941. Since 2000 the site has just consisted of Surf Beach and the unstaffed Lompoc–Surf Amtrak Station. California State Route 246 used to run to Surf, but in 1984 the highway was truncated at Lompoc and the road from Lompoc to Surf is designated West Ocean Avenue. Sections of Surf Beach are closed between March 1 and September 30 every year during the nesting season of the western snowy plover. The affected areas may be opened earlier than September 30 if all the newly hatched birds reach their fledgling stage beforehand. The closures are in place to protect the bird under the Endangered Species Act. If a set number of trespass violations have been reached during any nesting season (currently 50), the beach is closed entirely.

Space Launch Complex 6 (SLC-6, pronounced "Slick Six") at Vandenberg Space Force Base in California is a launch pad and support area. The site was originally developed starting in 1966, but no launches occurred until 1995, as it was repurposed sequentially for three programs that were subsequently cancelled. Initially to be used for Titan IIIM rockets and the Manned Orbiting Laboratory, these were cancelled before construction of SLC-6 was complete. The complex was later rebuilt to serve as the west coast launch site for the Space Shuttle, but went unused due to budget, safety and political considerations. The pad was subsequently used for four Athena rocket launches before being modified to support the Delta IV launch vehicle family, which used the pad for ten launches from 2006 until 2022. The last Delta IV launched in September 2022, and SpaceX leased SLC-6 in 2023 to convert it to launch Falcon 9 and Falcon Heavy starting in 2025.Launches from Vandenberg fly southward, allowing payloads to be placed in high-inclination orbits such as polar or Sun-synchronous orbit, which allow full global coverage on a regular basis and are often used for weather, Earth observation, and reconnaissance satellites. These orbits are difficult to reach from Cape Canaveral Space Force Station, where launches must fly eastward due to major population centers to both the north and south of Kennedy Space Center. Avoiding these would require major inefficient maneuvering, greatly reducing payload capacity.

The Santa Ynez River is one of the largest rivers on the Central Coast of California. It is 92 miles (148 km) long, flowing from east to west through the Santa Ynez Valley, reaching the Pacific Ocean at Surf, near Vandenberg Space Force Base and the city of Lompoc. The river drains the north slope of the Santa Ynez Mountains, the south slope of the San Rafael Mountains, as well as much of the southern half of Santa Barbara County. Its drainage basin is 896 square miles (2,320 km2) in area. The river's flow is highly variable. It usually dries up almost completely in the summer, but can become a raging torrent in the winter. The river has three dams which can impound a total of 210,000 acre-feet (260,000,000 m3) of water in wet years.
