National Captioning Institute also has an office in Santa Clarita, California.

The Enola Gay () is a Boeing B-29 Superfortress bomber, named after Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb in warfare. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused the destruction of about three quarters of the city. Enola Gay participated in the second nuclear attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in Nagasaki, a secondary target, being bombed instead. After the war, the Enola Gay returned to the United States, where it was operated from Roswell Army Air Field, New Mexico. In May 1946, it was flown to Kwajalein for the Operation Crossroads nuclear tests in the Pacific, but was not chosen to make the test drop at Bikini Atoll. Later that year, it was transferred to the Smithsonian Institution and spent many years parked at air bases exposed to the weather and souvenir hunters, before its 1961 disassembly and storage at a Smithsonian facility in Suitland, Maryland. In the 1980s, veterans groups engaged in a call for the Smithsonian to put the aircraft on display, leading to an acrimonious debate about exhibiting the aircraft without a proper historical context. The cockpit and nose section of the aircraft were exhibited at the National Air and Space Museum (NASM) on the National Mall, for the bombing's 50th anniversary in 1995, amid controversy. Since 2003, the entire restored B-29 has been on display at NASM's Steven F. Udvar-Hazy Center. The last survivor of its crew, Theodore Van Kirk, died on 28 July 2014 at the age of 93.

The Steven F. Udvar-Hazy Center, also called the Udvar-Hazy Center, is the Smithsonian National Air and Space Museum (NASM)'s annex at Washington Dulles International Airport in the Chantilly area of Fairfax County, Virginia. It holds numerous exhibits, including the Space Shuttle Discovery, the Enola Gay, and the Boeing 367-80, the main prototype for the popular Boeing 707 airliner. The 760,000-square-foot (71,000 m2; 17-acre; 7.1 ha) facility was made possible by a $65 million donation in October 1999 to the Smithsonian Institution by Steven F. Udvar-Házy, an immigrant from Hungary and co-founder of the International Lease Finance Corporation, an aircraft leasing corporation. The main NASM building, located on the National Mall in Washington, D.C., had always contained more artifacts than could be displayed, and most of the collection had been stored, unavailable to visitors, at the Paul E. Garber Preservation, Restoration, and Storage Facility in Silver Hill, Maryland. A substantial addition to the center encompassing restoration, conservation and collection-storage facilities was completed in 2010. Restoration facilities and museum archives were moved from the museum's Garber facility to the new sections of the Udvar-Hazy Center.

Sully Historic Site, more commonly known as Sully Plantation, is both a Virginia landmark and nationally registered historic place in Chantilly, Virginia.The earliest recorded claim to the land was made by the Doeg. Later the Lee family of Virginia owned the land from 1725 to 1839. Richard Bland Lee did not build the main house until 1794. Following the purchase by William Swartwort in 1838, Sully was used as a home, a working farm, or both by a series of private owners. Then in 1958, Sully was acquired by the federal government as a part of the area to be used for the construction of Dulles Airport. Today the Fairfax County Park Authority operates the site with a specific focus on the Lee family.

It also shares an education partnership with Centreville Presbyterian Church to improve student achievement.

Willard (also known as Willard Crossroads) was an unincorporated community located in what is now a part of Washington Dulles International Airport in the U.S. state of Virginia. The village was named after Joseph Edward Willard, a delegate to the Virginia General Assembly from 1893 to 1901, then Lieutenant Governor of Virginia. Although Willard lived in Loudoun County, he represented Fairfax County, because the village was only 1,500 feet (460 meters) from the county border. Willard owned a 50-acre (20-hectare) estate in Fairfax. His father was Joseph Clapp Willard, the owner of the famed Willard Hotel in Washington, D.C. Willard was at the intersection of Willard Road (now Stonecroft Boulevard) and Sterling Road (now Horsepen Road), surrounded by extensive farmland, housing, schools, places of worship, the Willard store (until 1907), and Blue Ridge Airfield (1938–1951). Willard stood west of Floris, north of Pleasant Valley, and south of Farmwell (now Ashburn). Willard was regarded as a crossroads and a distinctive community until construction of Washington Dulles International Airport began in 1958. Approximately 26 square miles (67 square kilometers) of Virginia land from Willard, Chantilly, Pleasant Valley, Sterling, and Ashburn was bought for construction. By the airport's completion, all remains of civilization before 1958 on this land had virtually disappeared, except a stretch of Willard Rd (used as a service road), and three storage outbuildings between Runways 1C/19C and 1R/19L.

Sentient is a classified artificial intelligence (AI)–powered satellite-based intelligence analysis system developed and operated by the National Reconnaissance Office (NRO) of the United States. Described as an artificial brain, Sentient autonomously processes orbital and terrestrial sensor data to detect, track, and forecast activity on and above Earth. The system integrates machine learning with real-time tip-and-cue functionality, enabling coordinated retasking of reconnaissance satellites without human input. Using multimodal intelligence data—from imagery and signals to communications and environmental feeds—Sentient is said to anticipate future events, prioritize targets, and serve as the predictive core of the NRO's Future Ground Architecture. Development and core buildout occurred from 2010 to 2016 under the NRO's Advanced Systems and Technology Directorate. Sentient is said to reduce analyst workload by automating routine surveillance tasks, enabling faster detection of threats and more responsive satellite coordination.

The NAVWAR Space Field Activity (NSFA) is one of three Echelon III activities under the Naval Information Warfare Systems Command (NAVWARSYSCOM) of the United States Navy, co-located with the National Reconnaissance Office (NRO) in Chantilly, Virginia. The activity was established to coordinate naval space and warfare systems activities within the National Reconnaissance Office. NSFA personnel provide naval warfare and acquisition expertise to national reconnaissance programs, coordinate naval space research, development, and acquisition activities with those same national reconnaissance programs, and provide and coordinate training and tools to enable the fleet to use national space capabilities.

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA.NRO is considered, along with the Central Intelligence Agency (CIA), National Security Agency (NSA), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, 2 miles (3.2 km) south of the Washington Dulles International Airport. The Director of the NRO reports to both the Director of National Intelligence and the Secretary of Defense. The NRO's federal workforce is a hybrid organization consisting of some 3,000 personnel including NRO cadre, Air Force, Army, CIA, NGA, NSA, Navy and US Space Force personnel. A 1996 bipartisan commission report described the NRO as having by far the largest budget of any intelligence agency, and "virtually no federal workforce", accomplishing most of its work through "tens of thousands" of defense contractor personnel.
