The factory footprint can be clearly seen in red, with some key landmarks such as Aycliffe Village in the bottom right, Heighington Station near bottom left and the Great North Road (A167). The factory was known as two sections, Heightington (West of Heighington Station) and Aycliffe.

The massive factory had about 1,000 buildings on a site which covered 867 acres. It was converted at the end of WWII into what we know today as Aycliffe Industrial Park. Some of the original ROF buildings still exist and are now used by modern day businesses.

Most of the munitions factory buildings still existed into the 1950s and as private firms took over the buildings, and modified them for their own purposes, the site was turned into the Aycliffe Industrial Park.
