lose-up, ground-level imagery of US military sites posed a "potential threat" to security, it said.
The move follows the discovery of images of the Fort Sam Houston army base in Texas on Google Maps.
A Google spokesman said that where the US military had expressed concerns, images had been removed.
Google has now been barred from filming and conducting detailed studies of bases, following the discovery of detailed, three-dimensional panoramas online - and in particular, views of the Texan base.
While [Google Earth] is a very useful tool, there has to be a balance

"Images include 360-degree views of the covered area to include access control points, barriers, headquarters, facilities and community areas," said the defence department in a statement quoted by AFP news agency.
It said such detailed mapping could pose a threat.
Google spokesman Larry Yu said the decision by a Google team to enter the Texas base and undertake a detailed survey, had been "a mistake".
He told the BBC News website that detailed study of such sensitive sites was not Google policy.
