Developed from the F-15 air superiority fighter, the 2-seat Strike Eagle is an extremely versatile deep interdiction strike aircraft, which still retains its air-to-air capability. In the years since Operation Desert Storm, the F-15E has replaced the F-111 Aardvark as the primary fighter-bomber in the U.S. Air Force. Using its LANTIRN (Low Altitude Navigation and Targeting, Infrared for Night) pods and other sophisticated avionics systems, it has the capability to deliver all types of conventional ordnance as well as the most sophisticated "smart" weapons in the inventory.
