The government does have the ability to turn off NDB & VOR if they think an
imminent attack on the US is probable. Google "SCATANA". (Security
Control of Air Traffic and Air Navagation Aids). You will find FAA order
7610.4 Special Military Operations. From what I've read, this dates back to
the 60's when there was a concern that the Soviet's could use our air
navigation aids to guide their missiles & bombers to the target.
SCATANA was partially invoked on 9/11 to order all civilian aircraft out of
the U.S. skies but NOT to also disable the air navigation aids. There is
an interesting article on this in the Bulletin of the Atomic Scientists at
