F/A 18 super hornet

The Boeing F/A-18E Super Hornet and related twin-seat F/A-18F are twin-engine carrier-capable multirole fighter aircraft variants based on the McDonnell Douglas F/A-18 Hornet. The F/A-18E single-seat and F/A-18F tandem-seat variants are larger and more advanced derivatives of the F/A-18C and D Hornet.

The Super Hornet has an internal 20 mm M61 rotary cannon and can carry air-to-air missiles and air-to-surface weapons. Additional fuel can be carried in up to five external fuel tanks and the aircraft can be configured as an airborne tanker by adding an external air refueling system

The Hornet and Super Hornet share many characteristics, including avionics, ejection seats, radar, armament, mission computer software, and maintenance/operating procedures. The Super Hornet is largely a new aircraft at about 20% larger, 7,000 lb (3,200 kg) heavier empty weight, and 15,000 lb (6,800 kg) heavier maximum weight than the original Hornet. The Super Hornet carries 33% more internal fuel, increasing mission range by 41% and endurance by 50% over the "Legacy" Hornet.

The empty weight of the Super Hornet is about 11,000 lb (5,000 kg) less than that of the F-14 Tomcat which it replaced, while approaching, but not matching, the F-14's payload and range. As the Super Hornet is significantly heavier than the "legacy" Hornet, the catapult and arresting systems must be set differently. To aid safe flight i and prevent confusion in radio calls, the Super Hornet is informally referred to as the "Rhino" to distinguish it from earlier Hornets.

Survivability is an important feature of the Super Hornet design. The U.S. Navy took a "balanced approach" to survivability in its design. This means that it does not rely on very low-observable technology, i.e. stealth. Instead, its design incorporates a combination of signature reduction, advanced electronic-warfare capabilities, reduced ballistic vulnerability, the use of standoff weapons, and innovative tactics that collectively enhance the safety of the fighter and crew.

Among the most significant aerodynamic changes are the enlarged leading edge extensions (LEX) which provide improved vortex lifting characteristics in high angle of attack maneuvers, and reduce the static stability margin to enhance pitching characteristics. This results in pitch rates in excess of 40 degrees per second, and high resistance to departure from controlled flight.
