The former Kirtland Air Force Base Precision Bombing Ranges N-1, N-2, N-3, N-4, Oil Refinery Target, and "New" Demolition Area are located on an area known as the West Mesa, approximately 2 miles west to 18 miles northwest of downtown Albuquerque, New Mexico.

In the early part of World War II, the U.S. leased approximately 10,345 acres of land from the City of Albuquerque.  The land was owned by the State of New Mexico and the Santa Fe Pacific Railroad and leased to the City of Albuquerque, who in turn, subleased it to the U.S. Government.  This acreage, along with 4,790 acres transferred from the Department of the Interior, was leased for building precision bombing ranges.  Real estate documents accurately describe the location of the land designated for these ranges.

Currently, the West Mesa is largely empty rangeland.  The City of Albuquerque operates the Albuquerque Shooting Range, the Albuquerque/Bernalillo County Water Utility Authority Soil Amendment Facility, and the Double Eagle II Airport, which is a small airstrip for private planes.  Eclipse Aviation is currently building manufacturing facilities Southeast of the Double Eagle II Airport.
