Itthaporn led a team of senior officers and reporters to inspect the Air Force headquarters.
The water was mostly one-metre high. The Air Force airport was about 1.3-metre under water.
Itthaporn said the Air Force was still taking care of some 50 flood evacuees at the head office.
He said most of Air Force officials and families have been evacuated after the floodwater was higher than the one-metre floodwall.
