The F-22 has long range detection as well. Janes reported in the late 90's that the Apg-77 has 2200 element AESA. The elements have already been upgraded once during production. They were cutting edge it really took the combined efforts of Raytheon and Northrop Grumman to pull the performance off. The AN/ ALR-94 itself is known to also be able to process information from emissions and guide a missile aiding the radar, from well past the radar detection ranges. The F-22 is also equipped with an IFDL data link for secure, LPI comms and cooperative engagement. Unlike previous generation sensor performance for VLO stealthy aircraft is more about how much they can hide away without giving there location away. Brute performance is only one aspect, LPI and the ability to network and exist in a complex Electro-magnetic environment while retaining survivability is the most important parameter that is looked at. The radar has also already demonstrated the ability to be used for ISR (passive) and communication. The EW modes are also a part of the 2017 increment and that capability is standard on the F-35. Beyond the next increment there are plans to switch/replace T-R modules of the F-22's radar with the F-35 T/R modules that are not only more advanced but the current standard out of the Maryland foundry.I got that part, but does not it mean a very different meaning to BVR combat if PAK-FA has a very long range target detection, additionally radar homing missile with mid-course guidance + long flight range will add to BVR effectiveness.
You also have to take into account the fact that missiles have been upgraded in the west. The AMRAAM has gotten 3 separate upgrades since the Raptor was in design and all these have heavily focused on having it perform against better ECM. The ECCM capability has had the most invested followed by making it more accurate and increase in range. The C5 was developed, the C7 developed followed by upgrades to both the C5 and C7 and now finally the D is coming online. There won't be an E and once the final Delta is delivered they will switch to a new program. In contrast the Russians never really created an inventory R-77's nor had procured any other similar weapon. They are essentially creating an inventory. of The problem however for the future is not so much as targeting at extreme long ranges but getting high PK's at medium ranges. You aren't going to pick up VLO aircraft from 100nm, you need to effectively overcome countermeasures at medium ranges. Targeting legacy aircraft is where the extreme long ranges do come into play but then you want to sneak into enemy territory for NT-ISR and to increase the lethality of your legacy fighters behind enemy lines.
Brute sensor strength is only going to get you detected earlier by the EW system onboard. The innovation and cutting edge work is in making signals LPI/LPD and that's what eats into the cost of developing advanced 5th generation aircraft. LPI/LPD involves exercising restraint, not broadcasting yourself, limiting your radar modes when operating in LPI and LPD and having secure and LPI data links so you build SA by emitting the least amount possible. You do not want to be blasting RF all over the place off of a VLO airframe, it defeats the entire point of stealth.
All this has to be kept in proper context. The Raptor is fully operational with the entire fleet in service. The PAKFA as per the last report from yesterday, is going to have between 12 and 50 operational birds by 2020, with the new engine beginning flight trials around 2017. The latest increment on the F-22 is currently in development and will be fielded by end of next year. the next increment runs from 2017 to around 2019-2020. By the time you are going to have a triple digit fleet of Su-50's in the RuAF you will most likely have an F-22 MLU.
