Folks, do keep in mind that the Extended Range AMRAAM (AMRAAM + ESSM) is claimed to fit inside the F-35A's weapons bays. If they can have an AL version of the AMRAAM ER then it also becomes an option on the 80 F-15EX's the USAF plans to field and will fit well into their concept of operations, making them quite useful beyond the homeland defense role.
AIM-260 is the successor to the AIM-120 and as such will first find its way into the bay of the F-22. It will likely share similar dimensions to the AMRAAM but just have better kinematics, and resistance to counter measures (and likely improved LO target performance)
The US Air Force's F-35A could field two examples of the larger missile, one in each internal weapons bay.
