Gw mau tau Varian dari McDonnell Douglas F-15E Strike Eagle

Two-seat all-weather long-range strike and ground-attack aircraft for the USAF. A total of 236 were built from 1985 to 2001.Davies 2002.

The F-15I is operated by the Israeli Air Force where it is known as the Ra'am (רעם – "Thunder"). It is a dual-seat ground attack aircraft powered by two Pratt & Whitney F100-PW-229 engines, and is based on the F-15E.

The F-15I Ra'am is similar to the F-15E, featuring some different avionic systems to meet Israeli requirements. Initially, Sharpshooter targeting pods designed for Israeli F-16s were fitted for night-time strikes, but were less capable than the LANTIRN pods used on USAF F-15Es; Israel later bought 30 LANTIRN pods. The F-15Is initially lacked Radar Warning Receivers; Israel installed its own Elisra SPS-2110 electronic warfare equipment as well as a new central computer and embedded GPS/INS system. All sensors can be slaved to the Display and Sight Helmet (DASH) helmet-mounted sight, providing both crew members a means of targeting which the F-15E lacks. The F-15I uses the APG-70I radar; its terrain mapping capability can locate targets difficult to spot while under adverse weather conditions. The radar can detect large airliner-sized targets at , and fighter-sized targets at ; it has a reduced resolution one-third below the standard USAF APG-70. In January 2016, Israel approved F-15I upgrades such as structural changes, an AESA radar, updated avionics, and new weapons.

The F-15K Slam Eagle (Korean: F-15K 슬램 이글) is a derivative of the F-15E, operated by the Republic of Korea Air Force. Several major components were outsourced to South Korean companies under an offset agreement, wherein South Korea was responsible for 40% of production and 25% of assembly. The fuselage and wings are supplied by Korea Aerospace Industries, flight control actuator by Hanwha Corporation, electronic jammer and radar warning receiver by Samsung Thales, head-up display, airborne communication system, and radar by LIG Nex1,"LIGNEX1 CO., LTD e-Catalog: Radar."  tradeKorea.com.

In 2002, ROKAF selected the F-15K for its F-X fighter program, during which the F-15K, the Dassault Rafale, the Eurofighter Typhoon and Sukhoi Su-35 were evaluated. A total of 40 aircraft were ordered, deliveries began in 2005. On 25 April 2008, a second batch of 21 F-15Ks were ordered, worth 2.3 trillion Korean won (US$2.3 billion). This second batch differs from first batch aircraft in having Pratt & Whitney F100-PW-229 (EEP) engines, license-produced by Samsung Techwin, for commonality with the KF-16 fleet."Boeing F-15K Eagle" , Flug Revue, 5 May 2008.  ROKAF had received 50 F-15Ks by June 2011. ROKAF expects the F-15K to be in service until 2060.

The F-15K has several features not typical to the F-15E, such as an AAS-42 Infra-red search and track, a customized Tactical Electronics Warfare Suite to reduce weight and increase jamming effectiveness, cockpit compatibility with night vision devices, ARC-232 U/VHF radio with Fighter Data Link system, and advanced APG-63(V)1 mechanical-scanned array radar. The APG-63(V)1 radar has common digital processing equipment with the APG-63(V)3 AESA radar, and thus is upgradable to an AESA radar via antenna replacement. The F-15K is equipped with the Joint Helmet Mounted Cueing System and weapons such as AGM-84K SLAM-ER, AGM-84H Harpoon Block II, and KEPD 350.

The F-15S is a variant of the F-15E supplied to the Royal Saudi Air Force (RSAF) in the 1990s. Saudi Arabia previously sought to buy up to 24 F-15Fs, a proposed single-seat variant, but was blocked by the U.S. Congress. The F-15S, initially referred to as F-15XP, is almost identical to the USAF F-15E, the only major difference in the AN/APG-70 radar's performance in synthetic aperture mode. 72 were built from 1996 to 1998. In October 2007, GE announced a US$300 million contract with Saudi Arabia for 65 GE F110-GE-129C engines for the F-15S.

The F-15SG (formerly F-15T) is a variant of the F-15E, ordered by the Republic of Singapore Air Force (RSAF) after a seven-year evaluation period involving five other fighters under consideration. The F-15SG was chosen on 6 September 2005 over the Dassault Rafale, the only other remaining aircraft in contention. On 22 August 2005, the US Defense Security Cooperation Agency (DSCA) notified Congress of a potential Foreign Military Sale (FMS) of weapons, logistics and training to Singapore; options included AIM-120C and AIM-9X missiles; GBU-38 JDAM and AGM-154 JSOW air-to-ground weapons, Night Vision Goggles and Link 16 terminals. The F-15F designation was also reserved. An order for 12 F-15SGs was placed in December 2005.

On 22 October 2007, the Singapore Ministry of Defence exercised an option for eight more F-15SGs within the original contract. Four more were later bought, increasing the total to twenty-four. The first F-15SG was rolled out on 3 November 2008; deliveries began in 2009; all 24 were declared operational in September 2013. Further F-15SGs were ordered, including 8 in 2010 and 8 in 2014, for a total of 40 F-15SGs by 2018.

The F-15 Advanced Eagle variant is an upgrade over previous models in that it features two additional underwing weapons hardpoints (increasing the number from nine to eleven); the option of a large area display cockpit; fly-by-wire controls; the Raytheon AN/APG-82(V)1 or AN/APG-63(V)3 active electronically scanned array (AESA) radar; General Electric General Electric F110-129 engines; digital Joint Helmet-Mounted Cueing Systems in both cockpits; and a digital electronic warfare system among other enhancements. In a typical escort configuration, the Advanced Eagle can carry 16 AIM-120 AMRAAM; four AIM-9X Sidewinder short-range missiles; and two AGM-88 HARMs. For precision strike, it can carry 16 Small-Diameter Bombs (SDBs); four AMRAAMs; one 2,000 lb Joint Direct Attack Munition (JDAM); two HARMs; and two fuel drop tanks.

The F-15SA (Saudi Advanced) is a version for the RSAF. It has a new fly-by-wire flight control system in place of the hybrid electronic/mechanical system used by previous F-15s, which allows for weapons carriage on the previously unused outer wing hardpoints. The F-15SA includes the APG-63(v)3 active electronically scanned array (AESA) radar, digital electronic warfare systems (DEWS), and infrared search and track (IRST) systems. It also had a redesigned cockpit once intended for the F-15SE.

The F-15QA (Qatar Advanced) Ababil is a variant for the Qatar Air Force. In November 2016, the US State Department approved the sale of up to 72 F-15QAs to Qatar in a $21.1 billion deal that included weapons, support, equipment, and training.http://www.dsca.mil/sites/default/files/mas/qatar_16-58.pdf In June 2017, Qatar signed a deal to buy 36 F-15QAs for US$12 billion. On 13 April 2020, the first F-15QA took its maiden flight. On 22 June 2021, Boeing announced that it will integrate an Elbit Systems anti-jamming systems into F-15QA, the anti-jamming systems allow F-15QA to fly into heavy electromagnetic interference environment uninterrupted.

F-15IA (Israel Advanced) adalah varian yang diusulkan untuk Angkatan Udara Israel berdasarkan F-15EX dan Advanced Eagle. Pasukan Pertahanan Israel menyetujui rencana untuk mengakuisisi 25 F-15IA yang baru dibangun dan meningkatkan 25 F-15I ke standar F-15IA pada Februari 2020.

In 2018, the USAF and Boeing discussed a proposed F-15X, a single-seat variant based on the F-15QA intended to replace the USAF's F-15C/Ds. Improvements includes the AMBER weapons rack to carry up to 22 air-to-air missiles, infrared search and track, advanced avionics and electronics warfare equipment, AESA radar, and revised structure with a service life of 20,000 hours. In the FY 2020 budget, the United States Department of Defense requested US$1.1 billion to procure 8 F-15EXs of a total planned procurement of 144 F-15EXs. The USAF opted for the F-15EX to maintain fighter numbers after the premature termination of F-22 production, its aging F-15C fleet, and F-35 delays. Although it is not expected to be survivable against modern air defenses by 2028, the F-15EX could perform homeland and airbase defense, no-fly zone enforcement against limited or no air defense systems, and deploying standoff munitions.  In July 2020, the U.S. Defense Department ordered eight fighters over three years for $1.2 billion.  In August 2020, the Air Force announced plans to replace the aging F-15Cs in the Florida and Oregon Air National Guards with F-15EXs. The F-15EX made its maiden flight on 2 February 2021. The first F-15EX was delivered to the USAF on 10 March 2021, and was flown to Eglin Air Force Base in Florida for further testing. On 7 April 2021, it was announced that the aircraft has been officially named Eagle II.
