 F-15C


Design of the McDonnell Douglas F-15 Eagle was started in the late Sixties. The Air Force wanted a single air-superiority fighter able to defeat the Mach 3 MiG-25 Foxbat, the MiG-21 Fishbed, and the MiG-23 Flogger.


The YF-15 flew for the first time on 27 July 1972, and most of the major test hurdles had been successfully negotiated by late 1974, clearing the way for the Eagle to join TAC’s inventory. Also covered by the initial contract was the manufacture of two TF-15A two-seat operational trainers, later redesignated F-15Bs. On 14 November 1974 President Gerald Ford formally accepted the first aircraft (actually a two-seat TF-15A designated F-15B) to be handed over to TAC at Luke AFB, Arizona.

The first two models to enter service were the F-15A single-seater and TF-15A (later F-15B) combat-capable tandem two-seater. Both variants had the APG-63 radar and 10855kg Pratt & Whitney F100-P-100 afterburning turbofans, with AIM-7 Sparrow air-to-air missiles along the bottom of its large inlet ducts and 20mm cannon mounted in the right inboard wing. The two-seat F-15B combat trainer which first flew on 7 July 1973 is about 360kg heavier than the F-15A fighter, but retains most of its combat capability.  The Eagle is equipped with Hughes APG-63 pulse-Doppler radar with computerised data-processing and the F-15 pioneered the HOTAS (hands on throttle and stick) concept.

The 1st Tactical Fighter Wing at Langley AFB, Virginia, was the first USAF recipient of the F-15A, while the first operational aircraft in Europe were assigned to the 36th TFW at Bitburg AB, West Germany.

The production totalled 366 and 58 respectively for the US Air Force plus 19 and two respectively for the Israeli Air Force.

Continuing procurement of the F-15A variant enabled two more TAG wings and one more USAFE squadron to be equipped between 1977-9, production thereafter switching to the F-15C and the basically similar two-seat F-15D.

In June 1979 deliveries of the improved and more advanced F-15C single-seat (flown for the first time on 27 February 1979) and F-15D two-seat models began. Equipped with AGP-70 radar (with a programmable digital signal processor, synthetic-aperture ground mapping and track-while-scan air-to-air capability), an uprated powerplant, and provision for low-drag conformal packs carrying fuel and fitted with tangential attachments for weapons. The two variant were built for the USAF, Israel and Saudi Arabia and are still operated today. These variants were also built under licence in Japan by Mitsubishi and designated F-15J.

In addition, it is also compatible with the company-developed FAST (Fuel And Sensor Tactical) packs, whereby conformal fuel tanks and/or sensor packages can be attached to the outside of each air inlet. Extra fuel tanks conform to the sides of the fuselage and hold an additional 10,000 lb / 4536 kg of fuel to supplement the 11,600 lb / 5260 kg of internal fuel, or a variety of sensors (such as reconnaissance cameras, in-fra-red equipment, radar warning receivers, laser designators and low-light-level television cameras to be carried. Thus, overall capability the Eagle has been significantly enhanced. Operational deployment of the F-15C and F-15D began in 1979. The 18th TFW at Yridena, Okinawa, was the first unit to receive this version, re-equipment of this Wing’s three squadrons being effected between September 1979 and April 1980. Subsequent deliveries were made to existing Eagle units, most of which were progressively re-equipped during the early 1980s.

The first single-seat air superiority F-15C incorporating MSIP enhancements was rolled out in June 1985.

 

 


Renowned as an extremely capable interceptor, the F-15D Eagle was modified in 1980 to perform in the all-weather interdictor role whilst still retaining the ability to operate as an air superiority aircraft. This private venture, first known as the Strike Eagle, first flown on 8 July 1980, was redesignated McDonnell Douglas F-15E Enhanced Eagle when the USAF expressed interest in the concept and conducted an evaluation between November 1982 and April 1983. Together with the delta-winged General Dynamics F-16E, the Enhanced Eagle was competing for selection in the USAF's Derivative Fighter Program as a supplement and eventual replacement for the General Dynamics F-111.

The dual-role F-15E Strike Eagle is basically a converted F-15B/D trainer for the ground-attack role. It has a total of 18 external hardpoints.

On 11 December 1986 the F-15E made its first flight and the US Air Force announced that it was to order 392 examples though this requirement was later reduced to 200 and deliveries began in 1988, initially to the 405th TTW for training and then the 4th TFW for operations, replacing the F-4E. The rear cockpit of the prototype (a converted F-15B trainer) has been fitted with four multi-purpose cathode ray tubes (CRTs) for information display to the systems operator and three more CRTs are to be installed for the pilot in production versions.


Beneath the nose-cone, high resolution radar provides long-range ground-mapping of remarkable clarity, whilst forward looking infra-red (FLIR) gives close range images of similar quality. In combination, these systems allow rapid target identification in all weathers and ensure accurate weapon delivery. Ordnance carriage has been improved by addition of bomb attachment points on the 'conformal' wing-root fuel and sensor packs, resulting in less drag and freeing wing pylons for additional fuel tanks. Called Tangential Carriage, the modification extends the Eagle's endurance by 40 per cent in some cases. During proving trials, the F-15E demonstrated an ability to take off at a weight of 34020 kg (75,0001b), some 3175kg (7,0001b) above the previous maximum.

The type has an advanced nav/attack system with APG-70 main radar as well as several radar and infra-red navigation and targeting options displayed to the rear seat, leaving the pilot free to concentrate on tactical flying using his head-up display. Equipment installed in the F-15E in-cludes the LANTIRN night nay/attack pod system, FLIR sensors, threat-warning dis-plays, digital map displays, APG-70 radar, a wide-angle HUD an improved mission compu-ter and provision for AIM-120 AMRAAM mis-siles and the integral M61 Vulcan cannon.

21 Strike Eagles were exported to Israel designated F-15I.
The Israeli Defence Force/Air Force aircraft have been involved in several dogfights with Syrian MiG-21s and MiG-23s and are officially confirmed as having shot down at least one MiG-25. On 7 June 1981, Israeli F-15s escorted F-16s making the strike against Iraq's Osirak nuclear powerplant, covering a radius of 966km.

The first F-15J Eagle assembled by Mitsubishi in Japan from components supplied by McDonnell Douglas made its maiden flight at Nagoya on 26 August. Seven more F-15Js single-seat version based on F-15C were to be assembled by August 1982, leading to manufacture by Mitsubishi against contracts placed for a total of 45 F-15Js and 12 two-seat F-15DJs (including two aircraft assembled in the USA by McDonnell Doug-las). Funding of 43 more F-15Js in the FY82 budget brought total procurements to 100. Mitsibishi produced 213 McDonnell Douglas F- 15J/DJ fighters for the JASDF by 1998.

Korea ordered the Boeing F-15K to replace its F-4 Phantom II fleet. The F-15K is more advanced than the original F-15E, it has better radar and improved systems and a helmet-mounted cueing system.

Saudi Arabia ordered the F-15 variant and took delivery of 72 downgraded F-15Es, redesignated F-15S.

The F-15 Eagle has a perfect combat record of 101 victories and zero defeats. F-15s downed four Mig-29 fighters during the Balkan conflict and 33 of the 35 fixed-wing aircraft Iraq lost in air combat during Operation Desert Storm.

Singapore ordered the F-15SG (previously known as F-15T), another customized advanced derivative of the F-15E Strike Eagle, to replace the A-4 Skyhawk in the ground-attack role.

The McDonnell Douglas F-15S/MTD, AF71290, is the prototype F-15B modified under a $US117.8 million programme for the US Air Force Wright Aeronautical Laboratories to investigate short take-off and landing using vectored thrust jet nozzles and canards mounted on the engine intakes. The aircraft's first flight was made on 7 September 1988 and after the fitment of the thrust vectoring reversing nozzles on the jet pipes these were flown for the first time on 10 May 1989. The aircraft was involved in a 13 month, 100 flight test schedule at Edwards. The aircraft's controllable canard foreplanes are adapted tailplanes from the F/A-18 Hornet and can operate independently of each other for pitch and roll manoeuvres having a 20 degree dihedral.

The US signed a US$29.4 billion  deal to sell 84 new F-15 fighter jets to Saudi Arabia in December 2011. The sale includes the 84 advanced Boeing F-15SA fighters with Raytheon Co radar equipment and digital. electronic warfare systems. Also included are upgrades that wilI bring Saudi Arabia's 70 older F-15s up to the new standard, as well as HARM, AGM-88 AntiRadiation Missfies; Laser JDAM and Enhanced Paveway munitions and related equipment and services. The first new F-15s' were expected to be delivered to Saudi, Arabia in early 2015.

By 1990, since the development two-seat Strike Eagle was displayed in 1984, this all-weather interdictor/strike aircraft has entered service with the USAF's 4th TFW and production of 200 was underway. Powered by 23,800 lb st (10 800 kgp) P& W F100-PW-220s, the F-15E The F-15E has a range of 2,400 nm (4,445 km).
