The Hornet replaced the MiG-21bis and Saab 35 Draken in Finnish service. The Finnish Hornets were initially to be used only for air defense, hence the F-18 designation. The F-18C includes the ASPJ (Airborne Self-Protection Jammer) jamming pod ALQ-165. [80] The U.S. Navy later included the ALQ-165 on their F/A-18E/F Super Hornet procurement.
The Hornet proved to be effective but limited in combat radius. The concept of an enlarged Hornet was first proposed in the 1980s, which was marketed by McDonnell Douglas as "Hornet 2000". The "Hornet 2000" concept was an advanced F/A-18 with a larger wing and a longer fuselage to carry more fuel and more powerful engines. [5] [6]
For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum ...
The F-14, F-15, and the Tornado were rejected due to their high purchase price, while Dassault dropped out of the competition. The F-18L combined the systems and twin-engine layout of the F-18 that Air Command favored with a lighter land-based equipment setup that significantly improved performance.

Advanced Super Hornet; Conformal fuel tanks are mounted above the wings to replace the drag of underwing tanks. Combined, they carry 1,590 kg (3,500 lb) of extra fuel, while adding extra lift and expanding combat radius by 130 nmi (240 km) with a small transonic acceleration penalty.

With a fuel fraction of nearly 85%, the GlobalFlyer could carry 5 times its weight in fuel.. In aerospace engineering, an aircraft's fuel fraction, fuel weight fraction, [1] or a spacecraft's propellant fraction, is the weight of the fuel or propellant divided by the gross take-off weight of the craft (including propellant): [2]
The General Electric F414 is an American afterburning turbofan engine in the 22,000-pound (98 kN) thrust class produced by GE Aerospace (formerly GE Aviation). The F414 originated from GE's widely used F404 turbofan, enlarged and improved for use in the Boeing F/A-18E/F Super Hornet.
