Wormingford was originally earmarked for an Eighth Heavy Bomb Group, being built by Richard Costain Ltd. and helped by a number of sub contractors during the period 1942/1943. The airfield had a 2,000-yard main runway on an E-W axis and two intersecting runways of 1,400 yards each along with the USAAF standard fifty hardstands, two T2 hangars, one each side of the airfield, Mark II lighting and temporary building accommodation for 2,900 personnel. The technical area was on the southern side of the airfield and the camp sites dispersed to the south and east in and around the village of Fordham.
