I would agree (missing village et al!) - Sleap
*edit*
Evidence (as requested):
Second photo shows small meandering water course on the near side of the airfield boundary - looking south over Sleap airfield (in Google Earth) gives same runway layout and the small water course still exists just north of the airfield.
Also, the first photo has a date of 1942 - Sleap didn't open till 1943 so the "under construction" phase would tally datewise.....
