Ramjet has a large drag area hence loss of kinetic energy so early, only advantage of Ramjet engine is extended NEZ, that's why USA/China wont working on Ramjet powered AAM/BVR, only Russia and now EU have Ramjet powered BVR

Extended NEZ is the biggest threat if paired up with medium/long range AAM.

It can only be replaced by hypersonic AAMs

hyper sonic AAMs are already in service like R-37 which have speed of Mach-6 for Mig-31BM/ and USN retired AIM-154 had speed of Mach-5+

Are you sure? AFAIK is the AIM-54 retired and the R-37 never entered service.

Ticket to hell !!!
What a beast they are, just read about them. AIM-54*
Does China have anything in that category ?

BTW Russia intends to integrate this with SU-35 as well

According to Wikipedia AIM-154 retired along with F-14 and again from Wikipedia R-37 is in the weapon system of Mig-31BM

AIM-154 had a range of 190 KM, almost same as PL-15, and as for R-37 its range consider to be 300-400 km and its main mission is to shot down AWACS/Tankers and other ISR aircraft not Fighter jets, and China developing similar type of BVR comparable to R-37 named PL-XX

Then IMO Wiki is wrong ... will check.

I am confirmed about AIM-154 retirement, but induction R-37 for Mig-31BM is 50/50

Or you can have a two-stage pulse rocket like PL-15. First stage steers the missile towards target. When the guidance locks on to target, second stage is activated to increase NEZ.

The range is about 140km, somewhat shorter than widely reported.

AIM-54 cannot really hit fighter jet at long range. In fact anything longer range than 150km has hard time hitting target because of loss of energy. To improve range, French use ramjet in Meteor so they can still reliably hit targets above 150km. China uses ramjet on several secret missiles now and PL-15 has dual motor to counter the fighter's dodging. PL-21 the long thin missile is similar to AIM-54 but lower drag. It is hard to hit fighter targets but designed for refuel plane or AWAC or transport. R-37 is similar to these as well. Huge drag coefficient just big fuel tank and big rocket or ramjet.

Truly the best form is ramjet but with different design to Russian Kh style or Chinese YJ style. Japanese ASM-3 shape for anti-ship and French Meteor shape is better. Chinese anti air missile has several like these but not shown except in some old diagrams from 10 years ago. Even better than these is another type that can in theory reliably kill fighter agile small targets from more than 300km with same probability as AIM-120D or PL-15. These launch missiles from a larger missile platform but must be dropped from large aircraft flying higher altitude and speed like JH-xx or H-20. Development must be together.
