Birch was known by the USAAF as USAAF Station AAF-149 for security reasons and was referred to as such, instead of by location. Its USAAF Station Code was "BR". ==Current use==
Current use
After release from military control, the airfield was returned to agricultural use. Today, most of the concreted areas have been removed for hardcore, leaving single-tracked farm roads along the main runway, one secondary runway, and parts of the perimeter track. Blind Lane (a public road) now runs along the other secondary runway (02/20), its original course having been displaced when the airfield was built. Some hardstanding is used by Essex Council for garden waste composting, the main site being accessed via the main runway. A few loop hardstands remain intact, off the remains of the single-tracked perimeter track along the north side of the airfield. However, other than these farm roads, there is little remaining of a wartime airfield that was never used, other than some ghostly disturbed areas visible in aerial photography. These represent loop dispersal hardstands and the long-since-removed perimeter track. ==See also==
