The modernization will last from 2024 to 2034. The central point will be the installation of a radar with an actively phased antenna array. It will not replace the Raytheon AN / APG-63 (V) 1 radar station.

There is currently no information about which radarwill be installed on Slam Eagle aircraft. One of the options is APG-63(V)3. The F-15 Eagle fighters in the USA, Singapore and Saudi Arabia are equipped with such a radar.

The second alternative is N/APG-82(V)1.This radar is installed on the upgraded F-15E Strike Eagle and F-15EX Eagle II aircraft in the United States, as well as on the Japanese F-15J. The system is characterized by increased range, accuracy and reliability. An active phased array radar will allow aircraft to detect cruise missiles and drones. A less likely option is a radar being developed for the South Korean JF-21 Boramae fighter by Hanwha Systems.
