A Republican and holdover from the Bush administration, Gates had agreed to stay on at the request of President Barack Obama. The move was intended to maintain stability at a time of two wars, although Gates has been open about his desire to return to civilian life in his home state of Washington.
In an interview published Monday, Gates told Foreign Policy magazine that leaving in 2011 makes sense. It would give him time to oversee the major offensive under way in Afghanistan but bow out before the 2012 presidential elections.
Gates has been defense secretary since December 2006.
