The U.S. Air Force is taking a long look down the road at buying and fielding new airplanes. Mandated by Congress, the "Aircraft Investment Plan" maps out how many planes the Air Force, U.S. Marine Corps and U.S. Navy plan to buy through 2020 and sets goals for 2021-2040. It does not include helicopters. The report calls for a joint approach to long-range strike and electronic warfare but does not drastically alter the Air Force's announced plans for its two main acquisitions this decade - the F-35 Lightning II and KC-X tanker. – Defense News
