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 Korean companies under an offset agreement, wherein Korea was responsible for 40% of production and 25% of assembly. 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, and engines by Samsung Techwin under license before final assembly at Boeing’s St. Louis facility.

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. ROKAF had received 50 F-15Ks by June 2011. ROKAF expects the F-15K to be in service until 2060.

The first batch (that is 40 airframes) F-15K Slam Eagles are equipped with General Electric made F-110- GE-129 engines, while the second batch (that is 21 airframes) Slam Eagles revert to the F100-PW-229-EEP engines- these are extended life engines, with EEP standing for Engine Enhancement Package. EEP engines add design improvements, HUMS prognostics and monitoring equipment and a slight boost to 29,100 pounds of thrust.
Beside technical and performance differences, the GE engine can immediately be recognized by its different jet exhaust nacelles as it is illustrated on the following pictures. (f-15e.info)
The F-15K variant has several features not typically found on F-15Es, 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 device, 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. Weapons such as AGM-84K SLAM-ER, AGM-84H Harpoon Block II, and JASSM have been integrated.

APG-63(V)1 mechanical-scanned array radar. With the A/G software of the APG-70 ported to the new platform, new sea surface and track modes and ground moving target track capability were added to meet the specific needs of the Republic of Korea. The new radar also has some kind of NCTR capabilities ( Non-Cooperative Target Identification/Recognition), although this area is highly classified. It is safe to say that the end result turned out to be the best F-15 radar in the world ever (including radars in other foreign versions, for example the F-15I Raam). (f-15e.info)
Cockpit: Many modifications can be found in and around the cockpit area. Boeing integrated the Joint Helmet Mounted Cueing System (JHMCS) into the array of upgraded displays. The cockpit interior lighting got modified to be compatible with night vision goggles ( NVG‘s). Boeing engineers changed the Up-Front Controller ( UFC) into a more modern flat panel display (the same display which can be found in the Saudi Arabian F-15S or in the Israeli F-15I Raam), which is also NVG compatible.
The Honeywell ADCP was also installed (this is the same ADCP as the Strike Eagle uses from construct number E227 and up) and it was prepared to be compatible with AIM-9X Sidewinder and AIM-120C AMRAAM air-to-air missiles. The ADCP is a PowerPC based hardware/software component which replaces the legacy CC and MPDP systems in generating images that are displayed on MPD‘s and MPCD‘s.
Counter Measures: Chaff and flare dispensers were installed as in the Israeli F-15I Raam. On the electronical front the Tactical Electronic Warfare System ( TEWS) suit received modifications as well. The ALQ-135 system got significantly improved and received a new designation as ALQ-135M (manufactured by Northrop Grumman). The new system uses a PowerPC based architecture instead of multiple processors, thus utilizing significant speed and memory enhancements. The new ALQ-135M also features sophisticated microwave power module (MPM) transmitter technology to reduce weight and increase jamming effectiveness. Band 1.5 and Band 3 are available with the new tool.

Weapons: All external hardpoints received a wiring compatible with the “J-series” range of weapons. Parallel to this modification the Programmable Armament Control Set ( PACS) also received modifications to handle changed in the hardpoint wirings. The jet was modified to be able to carry and employ the AGM-84D Harpoon anti-ship missile and the AGM-84E SLAM-ER air-to-ground missile. A new ADCP has been installed (the same as with F-15E jets from E227 and up) and made compatible with the AIM-9X and AIM-120C air-to-air missiles.

News surfaced around April 2010 that South Korea is looking for a cruise missile for their F-15K fleet that has a longer range than the SLAM-ER. They are especially interested in Lockheed’s AGM-158 JASSM stealth missile that USA and Australia are using.

Sensors: The F-15K received improved LANTRIN pods. The AAQ-14 pod features a new 3rd generation FLIR sensor which Boeing calls as “Tiger Eyes”. The pod gives the Slam Eagle IRST capabilities in air-to-air engagements.
Seoul to deploy Asia’s first Taurus missiles: Here
The air-to-ground guided Taurus KEPD 350 missile system has an overall weight of 1,400kg. It has a length of 16.7ft, wingspan of 6.7ft and diameter of 3.5ft. It falls under the MTCR category two weaponry.
The missile is made of modular sections which can be configured based on the individual missions. Its electronic systems are also modular. APCON has supplied the missile seeker electronics.
The Taurus missile is suitable for day and night and all weather deployment. It has low observability and terrain masking features for survivability. The modular design and reliability reduce the lifecycle cost of the system.
The missile carries about 481kg of inert multi-effect penetrator, high sophisticated and target optimised (MEPHISTO) dual stage warhead system for superior target penetration. The ignition system of the warhead is based on programmable intelligent multipurpose fuse (PIMPF).
The programmable fuse is designed with layer counting and void sensing technology. It was developed by TDW Gesellschaft für verteidigungstechnische Wirksysteme.
The blast and fragmentation capabilities eliminate the collateral damage to civil facilities near the target. The stand-off and precision capabilities of the missile and deployment range of more than 350km ensure maximum safety to the aircraft and crew.
Taurus KEPD 350 is powered by Williams P8300-15 Turbofan engine which provides the missile with a cruise speed of about Mach 0.6 to 0.95 at very low altitudes. The missile has a range of up to 500km (270nm) which is about 15% more than the ones propelled with JP10 fuel.
Navigation of the missile is controlled through Tri-Tec navigation system. It combines data from an inertial navigation system (INS), MIL-global positioning system (GPS), terrain reference navigation (TRN) and infrared seeker based image based navigation (IBN) sensors.
The missile can also navigate long distances without the GPS subsystem. It is equipped with an integrated mission planning system to determine its flight path.
