fuel and more powerful engines. The end of the Cold War led to a period of military budget cuts and considerable restructuring. At the same time, U.S. Naval Aviation faced a number of problems. The McDonnell Douglas A-12 Avenger II was canceled in 1991 after the program ran into serious problems; it was intended to replace the obsolete Grumman A-6 Intruder. The Navy considered updating an existing design as a more attractive approach to a clean-sheet program. As an alternative to the A-12, McDonnell Douglas proposed the "Super Hornet" (initially "Hornet II" in the 1980s), an improvement of the successful previous F/A-18 models, which could serve as an alternate replacement for the A-6 Intruder. In addition, the Hornet itself lacked sufficient bringback capability, or the ability to recover unused weapons aboard aircraft carriers. The next-generation Hornet design proved more attractive than Grumman's Quick Strike upgrade to the F-14 Tomcat, which was regarded as an insufficient technological leap over existing F-14s. At the time, the Grumman F-14 Tomcat was the Navy's primary air superiority fighter and fleet defense interceptor. Then-Secretary of Defense Dick Cheney described the F-14 as 1960s technology, and drastically cut back F-14D procurement in 1989 before cancelling production altogether in 1991, in favor of the updated F/A-18E/F. The decision to replace the Tomcat with an all-Hornet Carrier Air Wing was controversial; Vietnam War ace and Congressman Duke Cunningham criticized the Super Hornet as an unproven design that compromised air superiority. In 1992, the Navy canceled the Navy Advanced Tactical Fighter (NATF), which would have been a navalized variant of the Air Force's Lockheed Martin F-22 Raptor. As a cheaper alternative to NATF, Grumman proposed substantial improvements to the F-14 beyond Quick Strike, but Congress rejected them as too costly and reaffirmed its commitment to the less expensive F/A-18E/F. Testing and production The Super Hornet was first ordered by the U.S. Navy in 1992. The Navy retained the F/A-18 designation to help sell the program to Congress as a low-risk "derivative", though the Super Hornet is largely a new aircraft. The Hornet and Super Hornet share many characteristics, including avionics, ejection seats, radar, armament, mission computer software, and maintenance/operating procedures. The initial F/A-18E/F retained most of the avionics systems from the F/A-18C/D's configuration at the time. The design would be expanded in the Super Hornet with an empty weight slightly greater than the F-15C. The Super Hornet first flew
