The airfield was acquired by the War Department in August 1942 for use as an auxiliary air field for Douglas Army Airfield, Arizona. A total of were acquired by the War Department. Improvements included three bituminous taxiways, a concrete parking apron, 38 buildings, and 18 miscellaneous structures. Four ordnance-related structures were also identified, as well as two ammunition storage facilities. The Hereford AAF had housing capacity for 598 troops. According to the 2011 Archive Research Site Summary, historic construction maps of the airfield depict a skeet range southeast of the runways. It is unknown, however, whether the skeet range depicted in the fieldprogress report was ever constructed. Due to its mission of training bomber crews, the longest runway at Hereford was 9,200’ long, which was significantly larger than the typical runway of a World War II era training field. The airfield offered specialized night training in B-25 Mitchell and B-26 Marauder medium bombers. Historical documents also indicate that UC-78 aircraft were also flown out of Hereford AAF.
Civil use
Hereford AAF was declared surplus in 1945, and custody was assumed by the War Assets Administration, which sold the property. It was apparently abandoned by 1949. The War Assets Administration terminated the leases and sold the purchased property. The private owners apparently accepted ownership of some of the improvements in lieu of a restoration that might have been required. The Hereford airfield was apparently reused for some period of time as a civil airport, as the 1983 USGS topo map labeled the site as "Hereford Airport", but only depicted the north/south runway. The other two runways were not depicted at all. However, this rejuvenation of the field was evidently short lived as Hereford was not listed in the 1987 Flight Guide. It appears that one of the runways at Hereford was used by small private aircraft until about 1990, however as of the late 1990s, the entire Hereford site was privately owned. The site has been used for a ranching operation that included removal of almost all military structures & planting of grasses. The only evidence of the USAAF construction remaining was the deteriorating concrete parking apron, deteriorating bituminous runways & taxiway, and a pile of concrete tower bases. The north/south runway has been graded & reused as 'Airstrip Road', and one home uses the old 500’ x 500’ concrete apron as its driveway. It does not appear that the 1980s redevelopment resulted in any improvements to the site aside from a single prefab hangar & equipment shed which were erected on the apron. By 1998, the Hereford field was apparently abandoned again, and the land has become part of the suburbs of fast-growing Sierra Vista. Plots have been subdivided, and several houses ranging from simple to elaborate have been built on the site. As of 2011 the area has been extensively developed into rural residential homes, with the zoning lot size at 4 acres. The main runway is barely discerned as Airstrip Road, with the occasional piece of asphalt still visible in the grass.
