As the F-22 moves farther ahead of the battle lines, its passive sensors, which emit no electromagnetic energy that can be detected, can sniff out enemy aircraft formations, and this information can be shared with F-15C/Ds.
Such tactics will allow the F-22 to streak out ahead of the F-15s and club the enemy without them ever knowing they are there, all they would see are F-15C/Ds, with their radars blazing, many miles behind where the Raptors are silently operating. Additionally, once the F-22’s missile stocks run dry, they can switch to a scouting role, calling the shots for F-15s that are heavily laden with air-to-air missiles and operating safely behind the F-22’s stealthy screen. Boeing is well aware of this potential dichotomy and they are offering upgrades that could see F-15s carrying double the missile load they can today.
