This neighborhood, built in 1943, formerly served as the civilian housing area for the long-defunct Brewster Aeronautical Corporation, established in 1941, while the area was still referred to as Johnsville. The military facility was later known as Johnsville Naval Air Base, separated from the residential area and later became the Naval Air Development Center and was finally known as the NAWC, Aircraft Division, Warminster prior to its being decommissioned and closed by the US federal government in the mid-1990s. The community was previously named Lacey Park, for Pennsylvania Militia General John Lacey, who fought during the American Revolutionary War at the Battle of Crooked Billet, which took place near the neighborhood. It is still referred to colloquially as Lacey Park by local residents.
