F-16C Block 25
In 1994 Lockheed proposed the F-16 ES (Enhanced Strategic), a reach-extended version of the F-16 for the Israeli Strike Fighter competition. The aircraft was the first F-16 to be fitted with Conformal Fuel Tanks (CFTs) and was fitted with internal FLIR to reduce the drag associated with LANTIRN pods. When combined with a 320-gal. centerline tank and two 600-gal. underwing tanks, the F-16ES had an unrefueled mission radius of 1,025 mi. (with a typical strike load of two 2,000-lb. bombs and four air-to-air missiles), representing a 40% increase in range. After losing the Israeli contract to the F-15I, LMTAS re-used some ES technologies (like the CFTs) in new F-16 models like the Block 60.
