An army spokesman would not comment on whether the move had any relation to the Saturday downing of an unmanned aerial vehicle thought to have been sent into Israeli territory by the Lebanese militant organization Hezbollah.
Israel's armed forces have offered no official statement on where the drone came from or who its manufacturer might be. The Lebanese group has previously put other drones into the air and holds sophisticated Iranian armaments, AP reported.
The Patriot battery was moved to Haifa in northern Israel. Patriots have been fielded in the city during Israel's 2006 war against Hezbollah and at other times.
"We view with great severity the attempt to compromise Israeli air space and will consider our response in due course," Reuters quoted Israeli Defense Minister Ehud Barak as saying in prepared comments on Saturday after the drone was brought down close to the West Bank.
