The F-15SG (the Strike Eagle variant produced for the Republic of Singapore) is the newest and hottest F-15 version to date. Speaking of systems it is very similar to the Strike Eagle, but contains a few enhancements. Boeing made a difference in terms of systems, that's why the jet seems to be almost identical to the F-15E if looked at from the outside. However the real point scorers are hiding underneath the surface.

Differences from the F-15E

Engines: As with the Republic of Korea version, the F-15K Slam Eagle, Boeing equips the F-15SG with General Electric made F-110- GE-129 engines, instead of the 'traditional' Pratt&Whitney F100-PW-220 series engines. Besides technical and performance differences, the GE engine can immediately be recognized by its different jet exhaust nacelles.

Radar: It is arguably the most important difference between the F-15E and F-15SG models. The F-15SG is equipped with the APG-63(V)3 radar, the newest of the ultramodern AESA line developed by Raytheon.

Cockpit: Based on F-15K experiences 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). The old type UFC has been replaced by L-3 Communications flat panel UFC. 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 (this latter manufactured by Rockwell Collins).

Counter Measures: The EW systems are similar to the F-15K (see F-15K differences), including updated ALQ-135M system (manufactured by Northrop Grumman). The new ALQ-135M system uses a PowerPC based architecture instead of multiple processors, thus utilizing significant speed and memory enhancements. It 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. The F-15SG most probably includes BAE Systems' ADDS. Unconfirmed alternative analyst views suggest the EW systems may be similar to the Israeli F-15I Raam.

Sensors: The F-15SG uses the top-notch Sniper XR targeting pod. The targeting pod is attached under a new 3rd generation FLIR sensor which Boeing calls as "Tiger Eyes". The pod gives the F-15SG IRST capabilities in air-to-air engagements. Note that "Tiger Eyes" is also in service with the F-15K Slam Eagle version.

Communication: Not really a difference, since the Strike Eagle is also capable to carry, but the F-15SG is equipped with the Fighter Data Link ( FDL).

Weapons: The jet has been made fully compatible with the "J-series" range of weapons. The new ADCP (the same as with F-15E jets from E227 and up) is able to handle the AIM-9X and AIM-120C A/A missiles and the SDB series bombs.
