Araby is a historic house located near Mason Springs, Charles County, Maryland. An example of Federal architecture, it was built in the mid-1700s and underwent extensive renovations a hundred years later. Much of the house remains unaltered from that time.Merchant William Eilbeck built the plantation house, where he lived with his wife Sarah. He was one of the wealthiest men in Charles County, and held the rank of colonel in the local militia, and by 1745 was one of the gentleman justices of the local court. Eilbeck also had another plantation nearby, but only one child, a daughter Anne. In 1750, planter George Mason married Anne. The young couple lived with the Eilbecks while constructing Gunston Hall on his Virginia estates, and continued to visit Araby from time to time. Another of Anne's former suitors, George Washington, who owned a nearby property, was a frequent visitor. Sarah Eilbeck survived her husband, so Araby did not pass to their third grandson William Mason (1757-1820) until her death in 1780, when he was 23 and an officer in the Fairfax militia.It was listed on the National Register of Historic Places in 1974.

Naval Surface Warfare Center, Indian Head Division (NSWC IHD)—also known as Naval Support Facility Indian Head—is a United States Navy installation in Charles County, Maryland. Part of Naval Sea Systems Command (NAVSEA), it is one of ten divisions of the Naval Surface Warfare Center (WFC). Its mission is to research, develop, test, evaluate, and produce energetics (i.e., explosives, propellants, pyrotechnics, reactive materials, related chemicals and fuels and their application in propulsion systems and ordnance). The U.S. Navy's presence in Indian Head dates to 1890, when the Bureau of Ordnance dispatched Robert B. Dashiell to establish a naval ordnance center. Dashiell served as Inspector in Charge of Ordnance there from 1890 to 1893. During World War I, the facility served as Naval Proving Ground, Indian Head.

In addition, NSWC Indian Head has the WFC's largest concentration of Ph.Ds working in energetics, including the highest number of synthetic chemists, detonation physicists, and formulation scientists.The Division pursues basic research, applied technology, technology demonstration, prototyping, engineering development, acquisition, low-rate production, in-service engineering/mishaps and failure investigations, surveillance, and demilitarization.As the U.S. Navy’s lead technical authority in the United States, NSWC Indian Head performs more than 60% of all Navy energetics workload, and has an unmatched record of 13 Navy-qualified explosives used in 47 Navy, Army, Air Force, and Marine Corps weapons.
