As directed by the Defense Base Closure and Realignment Act (BRAC) and implemented by the 1991 and 1995 BRAC process, the Navy plans to close and dispose of the Naval Air Warfare Center Aircraft Division (NAWCAD) Warminster, located in Bucks County, Pennsylvania, approximately 18 miles (mi) (29 kilometers KM) north of Center City Philadelphia. This facility has been the principal Navy research, development, test, and evaluation center for naval aircraft systems and airborne and antisubmarine warfare systems. Because BRAC II provided specific direction regarding the relationship between the property disposal process and National Environmental Policy Act (NEPA) requirements, this Environmental Impact Statement (El S) has been prepared to address the probable impacts of the disposal and reuse of NAWCAD, and thereby to fulfill requirements for NEPA compliance. The Base Closure and Realignment Commission determined in 1991 that NAWCAD would be slated for a major realignment. The majority of the aircraft systems Research, Development, Test, and Evaluation (RDT & E) would be relocated to the Naval Air Warfare Center Aircraft Division Patuxent River, Maryland. A few specialized, immovable facilities would remain at NAWCAD. The dynamic flight simulator and the RDT & E Division would remain, and the Oreland Open Water Facility would remain government property under NAWCAD Patuxent River. Military family housing would be retained. All other tenant commands would be disestablished or relocated off the site. Subsequently, in 1995, the Commission recommended that several NAWCAD facilities designated to be retained by the Navy should, in fact, be closed and disposed of: the inertial laboratory (Bldg 108); the dynamic flight simulator buildings (Bldgs 70 and 72); and extensions of the main complex of buildings (Bldgs 125 and 138). The military family housing would be retained and.
