F18 Hornet


The McDonnell Douglas (now Boeing) F/A-18 Hornet is an all-weather carrier-capable multirole fighter jet, designed to attack both ground and aerial targets. Designed in the 1970s for service with the United States Navy and Marine Corps, the Hornet is also used by the air forces of several other nations. It has been the aerial demonstration aircraft for the U.S. Navy's Blue Angels since 1986. Its primary missions are fighter escort, fleet air defense, suppression of enemy air defenses (SEAD), interdiction, close air support and reconnaissance. Its versatility and reliability have proven it to be a valuable carrier asset, though it has been criticized for its lack of range and payload compared to its contemporaries.[2]

The F/A-18E/F Super Hornet is a distinct, evolutionary upgrade to the F/A-18 designed to serve a complementary role with Hornets in the U.S. Navy.[3

Origins
Development of the F/A-18 came as a result of the U.S. Navy's Naval Fighter-Attack, Experimental (VFAX) program to procure a multirole aircraft to replace the A-4 Skyhawk, the A-7 Corsair II, remaining F-4 Phantom IIs and to complement the F-14 Tomcat. Vice Admiral Kent Lee, then head of Naval Air Systems Command (NAVAIR), was the lead advocate for the VFAX against strong opposition from many Navy officers, including Vice Admiral William D. Houser, deputy chief of naval operations for air warfare - the highest ranking naval aviator.[4]


The YF-17 Cobra was navalized and developed into the F/A-18.In August 1973, Congress mandated that the Navy pursue a lower-cost alternative to the F-14. Grumman proposed a stripped F-14 designated the F-14X, while McDonnell Douglas proposed a navalized F-15, but both were nearly as expensive as the F-14.[5] That summer, Secretary of Defense Schlesinger ordered the Navy to evaluate the competitors in the Air Force's Lightweight Fighter (LWF) program, the General Dynamics YF-16 and Northrop YF-17.[6] The Air Force competition specified a day fighter with no strike capability. In May 1974, the House Armed Services Committee redirected $34 million from the VFAX to a new program, the Navy Air Combat Fighter (NACF),[6] intended to make maximum use of the technology developed for the LWF program.[5]


Redesigning the YF-17
Though the YF-16 won the LWF competition, the Navy was skeptical that an aircraft with one engine and narrow landing gear could be easily or economically adapted to carrier service, and refused to adopt an F-16 derivative. The Navy fought for and won permission to develop an aircraft based on the YF-17. Since the LWF did not share the design requirements of the VFAX, the Navy asked McDonnell Douglas and Northrop to design a new aircraft around the configuration and design principles of the YF-17. The new aircraft, designated the F-18, shared not a single essential dimension or primary structure with the YF-17. Secretary of the Navy W. Graham Claytor announced on 1 March 1977 that the name of the aircraft would be "Hornet".[5]
