Probably not in 10 years but in 20 years or more maybe some of the fighter jet fleets of the USAF are going to be replaced with a new kind of aircraft, namely specialized hunter and killer aircrafts.
This "hunter" aircraft would have a substantially larger fuselage compared to current fighters, maybe in the region of F-111. That hunter would have larger, more capable sensors with huge apertures. Large fuel tanks as well, coupled with engines with generators that are capable of generating electricity which could power these sensors and DEWs.
Now this hunter would not operate within the enemy airspace but would stay a step behind and control various kind of UAVs, of which some would act as the killer. These UAVs would sort of act like an external "module" of the hunters that are more simple and expandable than current UCAVs. For example the combat would be done by Longshot alike but supersonic UCAVs that have minimal sensors and equipped with intra-flight data link that connects it with other UAVs and most importantly the hunter aircraft. This hypothetical UCAV would be more effective than enlarging and extending the missiles themselves.
When the adversary tries to engage the hunter, either with PL-15-like long range missiles or missile launched from their own penetrating aircraft, it would be able to hard-kill it with its DEW. Maybe even employ some anti-AAM missile akin to CUDA. So it's kind of expanding from current form of MUM-T to a more specialized aircrafts that are, say, more alike the naval warfare than the traditional aerial combat.
I've thought of such aircraft due to recent reports on wargame outcomes that took place on the SCS or the far-east within the Chinese A2/AD. According to such reports, legacy fighter jets, even the F-35, were not able to provide deep-strike capabilities, not because of the lack of stealth or its avionics capabilities but rather down to the fact that the A2/AD which employs PL-15 like long range BVRAAM or SAM deterred most of the support aircrafts like the tankers to enter the airspace close enough. Fancy sensors and software are all moot if you can't physically reach your target. On the other hand those UAVs I've talked about could have more fuel capacity instead of the cockpit and other human-related systems.
Now that I've talked about it, this hunter aircraft sounds more like the traditional AEW&C aircraft, specifically the E-2D with NIFC-CA capabilities. It might be easier to understand this hunter aircraft as E-2D but one that is powered by turbofans and equipped with much smaller radar(still larger than that of traditional fighter jets) EO-DAS, EW capabilities, VLO design, DEW and can go supersonic. It also sounds like the B-1R but one that doesn't shoot the missiles itself but rather through UCAVs.
On the other hand, I think this hypothetical hunter aircraft is not all that different compared to what is currently envisioned as 6th generation fighter jets and to a certain extent even how the USAF is considering to operate 4th and 5th generation fighter jets together. The main difference would be that these 6th generation fighter jets still seem to focus on agility and has the capability to engage in combat themselves if necessary. My hypothetical hunter aircraft sacrifices the agility for more fuel, larger sensors and more provisions for DEWs. Also instead of combat capable fighter jets act as hunter and killer, what I'm thinking about is strictly hunter and strictly killer aircrafts. Reason behind this, apart from larger sensors is that the missiles are seemingly becoming more agile across wider flight envelop. Ramjet powered missiles already have considerably larger NEZ. Simplest solution to a larger NEZ is to stay out of it and shoot it down if they still come across.
Now I think there are some obvious issues with this concept, that it is rather specialized in high-intensity warfare that takes place in A2/AD airspace with considerable depth. More conventional fighter jet design would be suitable to situations where the theater of operation is way shallower and physically closer to the adversary, like that of central-eastern Europe, Israel, Taiwan and Korea. Also during peace time, it would probably be less suitable for missions like air patrolling and interception. That's why if anyone uses such kind of aircraft, I think it would be USAF. Maybe JASDF as well.
