The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research.As of 2016, NRL was a Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year.

Oxon Run is a tributary stream of Oxon Creek and the Potomac River in Prince George's County, Maryland, and Washington, D.C. In early maps, the stream is usually called "Oxen Run" and in 1892 the U.S. Geological Survey still labelled the stream as "Oxen Run" on its maps. Late in that year they changed the spelling they used, and others have followed suit, though it's unclear what led to the spelling change. Government officials and mapmakers often don't make a distinction between Oxon Creek and Oxon Run, instead treating Oxon Creek as a continuation of Oxon Run, but USGS still does. USGS first started labeling it as Oxon Creek in 1892.
