highly classified history. Primary names include Dreamland, Paradise Ranch Wikipedia, Watertown, Groom Lake Wikipedia, and Homey Airport

Military personnel, aerospace engineers, and government officials use several specific nicknames and official designations for the Area 51 facility:

• Dreamland: Originally used as the approach control call sign for the airspace surrounding the base, it later became a widely used nickname for the installation itself Wikipedia.
• Paradise Ranch: A name coined by Lockheed engineer Clarence “Kelly” Johnson in 1955 to make the remote, desolate test site sound more appealing to prospective workers [Wikipedia](https://en.wikipedia.org/wiki/Area_51, Dreamland Resort). Veterans and early workers often refer to it simply as “The Ranch” Dreamland Resort.
• Watertown: The official name given to the test site in 1956, named after CIA Director Allen Dulles’ hometown in New York Dreamland Resort. 
• Groom Lake: Refers to the geographic dry lakebed where the airfield was built 
• Homey Airport (KXTA): The official FAA and ICAO identifier for the military airstrip located inside the base 
• Restricted Area 4808 North (R-4808N): The official military designation for the highly classified special use airspace surrounding the facility

Area 2 is a historically significant 20-square-mile zone within the northern half of Yucca Flat at the Nevada National Security Site (formerly the Nevada Proving Grounds). It hosted 7 atmospheric tests (1952–1957) and over 130 underground nuclear tests, and it is the site of the massive 320-foot-deep Sedan Crater. [1, 2, 3]

The sector was a major hub for Cold War-era research, containing several distinct points of interest:

• Sedan Crater: Created on July 6, 1962, by a 104-kiloton thermonuclear explosive as part of the Plowshare Program. It is the deepest crater on the test site and is listed on the National Register of Historic Places. 
• The Area 2 Gun Turret: Built atop a tower, this turret was salvaged from a U.S. Navy Heavy Cruiser and utilized by the Lawrence Livermore Radiation Laboratory. It allowed scientists to rotate and elevate line-of-sight diagnostic equipment for multiple atmospheric nuclear tests without constructing new platforms each time. 
• Testing Legacy: Between 1952 and 1990, Area 2 was utilized for both single and simultaneous underground nuclear detonations, as well as post-Cold War subcritical and experimental weapon-physics testing. 

The NNSS remains an active, federally controlled facility, but the Department of Energy offers limited public access. 

Area 3 is a specific section of the Nevada National Security Site (NNSS)—formerly known as the Nevada Proving Ground and Nevada Test Site—located 65 miles northwest of Las Vegas. It primarily functions as a Radioactive Waste Management Site (RWMS) for the U.S. Department of Energy (DOE). 

Key details about Area 3 include:

• Waste Management Operations: Spanning approximately 119 acres, Area 3 is utilized for the permanent disposal of Low-Level Waste (LLW) and Mixed Low-Level Waste (MLLW) generated by DOE and Department of Defense facilities across the country. 
• Historical Context: The disposal cells in Area 3 were constructed by excavating and modifying the large subsidence craters formed by historic underground nuclear tests (such as the Jerboa test in 1963).
• Operational Status: The site previously entered cold stand-by in 2006 but was reopened to accept cleanup-related waste from the nearby Tonopah Test Range. It continues to be managed by the National Nuclear Security Administration (NNSA). 
• Site Visits: While Area 3 is part of the NNSS, public access is heavily restricted. The NNSA occasionally offers free historical bus tours of the larger NNSS facility, departing from the Atomic Museum in Las Vegas, although these programs are subject to strict security screening and scheduling changes.

Area 4, located in the central Yucca Flat basin of the Nevada National Security Site (NNSS), hosted over 40 nuclear detonations during the Cold War. Today, it is primarily known for the Big Explosives Experimental Facility (BEEF), which conducts non-fissile conventional high-explosive testing to simulate nuclear weapon behavior. 

The area has a distinct history and modern usage profile: 

• Historical Nuclear Testing: Area 4 was the site of five atmospheric nuclear tests (1952–1957) and 35 underground nuclear tests (mid-1970s–1991). 
• Japanese Village: Located in Area 4, this site consisted of authentic, simulated wooden Japanese houses constructed in 1962 for Project Ichiban/Operation BREN. It was used in conjunction with the U.S./Japanese Atomic Bomb Casualty Commission to research the shielding effects of typical Japanese housing and calculate radiation doses. 
• BEEF Facility: Currently operating in Area 4, this 10-acre secured compound features a control bunker, camera bunker, and gravel firing table. Managed by Los Alamos National Laboratory, it provides hydrodynamic testing capabilities that support stockpile certification without relying on fissile material.

Area 5 is a specific operational section within the Nevada National Security Site (NNSS), located about 65 miles northwest of Las Vegas. Originally established as the Nevada Proving Grounds in 1950, Area 5 contains the famous Frenchman Flat dry lake bed, where the U.S. conducted its first atmospheric nuclear detonation in January 1951.

Area 6 is a restricted, highly secure section of the Nevada National Security Site (NNSS) (formerly the Nevada Proving Grounds), located roughly 65 to 80 miles northwest of Las Vegas in Nye County. It is primarily known for housing a 5,000-foot asphalt runway and serving as a testing ground for various aerospace, remote sensing, and national security projects. 

Historically part of the Yucca Flat basin—the most heavily nuclear-blasted area in the world—Area 6 and the broader NNSS were the primary locations for hundreds of atmospheric and underground nuclear detonations between 1951 and 1992. Today, the proving ground operates as an active government research facility under the National Nuclear Security Administration, focusing on conventional high-explosive testing, non-proliferation training, and managing the environmental impact of past nuclear blasts. 

Area 7 is one of the distinct nuclear testing and operations zones within the 1,375-square-mile Nevada National Security Site (formerly the Nevada Test Site / Nevada Proving Grounds). Located about 65 miles northwest of Las Vegas in Nye County, Nevada, the facility is federally restricted and closed to the public except through official, pre-arranged tours. 

Overview and Function

• Primary Role: Area 7 is situated within Yucca Flat, the heavily cratered central desert basin that hosted hundreds of the U.S. government’s underground nuclear weapons tests. 
• Historical Testing: Over 700 nuclear experiments were conducted in Yucca Flat. Detonations in or near Area 7 were designed to evaluate the physical effects of nuclear shockwaves and radiation on military equipment and structures. 
• Current Status: Nuclear testing ceased in 1992. Today, the site operates under the National Nuclear Security Administration to manage the nation’s nuclear stockpile through subcritical experimentation, nonproliferation training, and environmental cleanup. 

Area 8 is a historically restricted, rugged section of the Nevada National Security Site (NNSS) (formerly the Nevada Proving Grounds and Nevada Test Site). Located in Nye County, Nevada, approximately 65 miles northwest of Las Vegas, it was specifically designated for underground nuclear weapons effects testing and environmental monitoring during the Cold War. [1, 2, 3, 4]

History and Significance

• Atmospheric and Underground Tests: Throughout the 1950s and 1960s, Area 8 (part of the larger Yucca Flat region) hosted several underground nuclear detonations designed to measure weapon survivability and blast effects on military equipment. [1, 2, 3]
• Corrective Action Unit (CAU) 550: Area 8 is largely known today in legacy management as CAU 550, which includes sites like “Smoky,” “Ceres,” “Oberon,” and “Titania.” These were historical underground tests conducted between 1957 and 1962. [1, 2]
• Environmental Remediation: The U.S. Department of Energy (DOE) Environmental Management program continues to monitor and remediate radioactive subsidence craters and soil impacts in Area 8. The ultimate goal is to complete site closures and post-closure monitoring by 2030. [1, 2]

Access and Modern Operations

• Restricted Access: Area 8 remains an active experimental and national security reserve. Unescorted public access is strictly prohibited and violators are subject to federal penalties. [1, 2, 3]
• Public Tours: The NNSS provides free monthly public tours. However, due to the high volume of interest, these community tours have been canceled through 2026. [1, 2, 3]

Located in the northeast quadrant of the Yucca Flat weapons test basin within the Nevada National Security Site (formerly the Nevada Proving Grounds), Area 9 covers roughly 52 square kilometers (20 square miles). It is historically significant for hosting 117 total nuclear detonations, including the largest atmospheric nuclear test ever conducted in the continental United States. [1, 2, 3]

Specific details regarding the area’s history and current status include:

• The “Hood” Test: On July 5, 1957, Area 9 hosted the 74-kiloton “Hood” shot as part of Operation Plumbbob. Lifted by a balloon to 460 meters, the explosion was nearly five times larger than the bomb dropped on Hiroshima and remains the largest atmospheric test on the U.S. mainland. [1, 2]
• Nuclear Testing Totals: Between 1951 and 1958, the area hosted 17 atmospheric tests. From late 1961 to 1992, it was utilized extensively for 100 underground nuclear tests. [1]
• Waste Disposal Site: The northeast corner of Area 9 currently contains a Class III Solid Waste Disposal Site. It is located in a subsidence crater created by historic underground nuclear events and is used for the disposal of inert industrial and solid waste. [1]
• Public Access: Area 9 is heavily restricted and located within the active Nuclear Test Zone of the facility. The government occasionally provides public historical tours to other portions of the proving grounds, which can be explored via the Nevada National Security Site Monthly Tours page. [1, 2, 3]

Area 10 is located in Yucca Flat at the Nevada National Security Site (formerly the Nevada Proving Grounds). It is most famous for housing the Sedan Crater, the largest human-made crater in the United States, created by a 104-kiloton thermonuclear detonation on July 6, 1962. [1, 2, 3]

Area 10 was primarily used for vertical shaft underground testing. Because it is a secure federal facility, public access is heavily restricted.
