After review and checking around the area, it appears to be a former Israeli/Egyptian AF base, thats probably abandoned. It was either built by the
Egyptians an captured by the Israelis or built by Israel after the invasion for their fighters.
There is another one nearby:
Refidim Airbase
30°24'29"N 33°9'3"E
Cool find! Its amazing what you can find on these things! Hope my explanation helped.
