F-15 EX 3D model

In 2018, the United States Air Force (USAF) and Boeing discussed the F-15X or Advanced F-15, a proposed single-seat variant based on the F-15QA to replace USAF F-15C/Ds. Improvements included the AMBER (Advanced Missile and Bomb Ejector Rack) system to carry up to 22 air-to-air missiles, infrared search and track, advanced avionics and electronic warfare equipment, AESA radar, and revised structure with a service life of 20,000 hours.Single- and two-seat variants were proposed, called F-15CX and F-15EX respectively, with identical capabilities. The USAF opted for the two-seat variant, which can be flown either by a single pilot or by a pilot and WSO for complex missions and, someday, controlling collaborative combat aircraft. One reason for this decision is that only two–seat F-15 models remained in production.
