The F-15 Eagle aircraft is a series of air superiority fighters, designed for the United States Air Force. Production began with the F-15A single-seat and F-15B two-seat (trainer) versions; the current U.S. production versions are the F-15C and F-15D. In the system of fighter generations, it is usually considered fourth generation.

While an informal motto for the designers was "not a pound for air to ground", a two-seat fighter-bomber variant, the F-15E Strike Eagle, has proved to be a formidable combat performer.

Role

Before the F-15E was developed, the F-15 series was seen as a "high end" air superiority fighter. Under John Boyd's concept of "high-low", the F-16 Fighting Falcon was the Air Force low end, intended as a fighter-bomber although having significant air superiority capability.

The first F-15A flight was made in July 1972, and the first flight of the two-seat F-15B (formerly TF-15A) trainer was made in July 1973. The first Eagle (F-15B) was delivered in November 1974. F-15s can extend their range both with aerodynamically efficient conformal fuel tanks that effectively become part of the fuselage, as well as wing-mounted drop tanks. Still, they routinely use air refueling.

In January 1976, the first Eagle destined for a combat squadron was delivered. In 1983, a Multistage Improvement Program was begun, with the first production MSIP F-15C produced in 1985. Improvements included an upgraded central computer; a Programmable Armament Control Set, allowing for advanced versions of the AIM-7 Sparrow, AIM-9 Sidewinder, and AIM-120 AMRAAM air-to-air missiles; and an expanded Tactical Electronic Warfare System that provides improvements to the AN/ALR-56C radar warning receiver and AN/ALQ-135 countermeasure set.

The final 43 included a Hughes AN/APG-70 radar, of which Version 1 is a PESA system, but version 2, being deployed experimentally, is a radically improved APESA system

F-15C, D and E models were deployed to the Persian Gulf in 1991 in support of Operation Desert Storm where they proved their superior combat capability. F-15C fighters accounted for 34 of the 37 Air Force air-to-air victories. They have since been deployed for air expeditionary force deployments and Operation Southern Watch (no-fly zone in Southern Iraq), Operation Provide Comfort in Turkey, Operation Allied Force in Bosnia, Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq.

Foreign operators

There are a number of foreign operators, including Israel, Japan, and Saudi Arabia, with variants specific to national needs and U.S. export controls.

Defensive systems

For both electronic protection and infrared countermeasures, the AN/ALE-47 Countermeasures Dispenser System [CMDS], is a "smart" dispenser that can integrate with defensive avionics such as radar warning receivers, radar reflector (i.e., chaff) dispensers, radar jammers, as well as helping the pilot with situational awareness of the threat.

Successor

For the United States, the successor to the F-15 air superiority and probably advanced fighter bomber series is the F-22 Raptor.
