From 2002 to 2009, SACT has been a United States Flag or General officer, and dual-hatted as Commander of the U.S. Joint Forces Command, the post responsible for maximizing future and present military capabilities of the United States. His command is exercised from the Headquarters of Alliance Command Transformation in Norfolk, Virginia, United States, which is also where U.S. Joint Forces Command has its Headquarters.
Since 2009, the year France decided to fully participate in NATO structures following its withdrawal from the integrated military structure in 1966, a French General officer has held the position: General Stéphane Abrial from 2009 to 2012 and, currently, General Jean-Paul Paloméros. The first SACT was Admiral Edmund P. Giambastiani Jr. from 2002 to 2005, followed by General Lance L. Smith from 2005 to 2007, and then General James Mattis from 2007 to 2009.
Prior to 2002, before the reform, the then Supreme Allied Commander Atlantic (SACLANT), was responsible for safeguarding the Allies’ sea lines of communication, supporting land and amphibious operations, and protecting the deployment of the Alliance’s sea-based nuclear deterrent.
Allied Command Atlantic extended from the North Pole to the Tropic of Cancer and from the coastal waters of North America to those of Europe and Africa, including Portugal, but not including the Channel and British Isles, which were part of what was Allied Command Europe at the time (now Allied Command Operations).
