UNITED STATES - 18 FEBRUARY 2011 Participants: U.S. Air Force, U.K. Royal Air Force and Royal Australian Air Force NELLIS AIR FORCE BASE, Nev. -- Southern Nevada residents will notice an increase in military aircraft activity as the Air Force conducts Red Flag 11-3, Feb. 21 - March 11. Red Flag is a realistic combat training exercise involving the air forces of the United States and its allies. The exercise takes place north of Las Vegas on the Nevada Test and Training Range--the U.S. Air Force's premier military training area with more than 12,000 square miles of airspace and 2.9 million acres of land. With 1,900 possible targets, realistic threat systems and an opposing enemy force that cannot be replicated anywhere else in the world, Nellis and the NTTR are the home of a "peacetime battlefield," providing combat air forces with the ability to train to fight together, to survive together and to win together. The 414th Combat Training Squadron is responsible for executing Red Flag, which is one of a series of advanced training program exercises that organizations assigned to the U.S. Air Force Warfare Center administer at Nellis AFB and on the NTTR by. Red Flag 11-3 will mark the official transition to a three-week exercise. It will also undergo several changes to include cyberspace as a new domain in execution of Red Flag. For the first two weeks of Red Flag 11-3, more than 80 aircraft are scheduled to depart Nellis twice a day, with early launches around 11 a.m. and late launches around 7 p.m. During the third week, early launches change to 2 p.m. and late launches begin around 9:30 p.m. Aircraft may remain in the air for up to four hours. The flying times are scheduled to accommodate the other flying missions at Nellis and to provide Red Flag participants with valuable training in planning and executing a wide-variety of combat missions. The exercise involves a variety of U.S. forces aircraft, to include F-15s, F-16s, E-3s, E-8s, A-10s, B-2s, C-130s and KC-135s, from Nevada, Missouri, Georgia, New Mexico, Missouri, Nebraska, Texas, South Carolina and Washington. In addition to U.S. aircraft, the U.K. Royal Air Force will participate with GR4 Tornados and the Royal Australian Air Force will participate with their C-130s.
