Well, Im very new to this forum and have joined recently but I hold a lot of knowledge bout' the fact that we are talking about out here. When it comes to the future warfare, none of us can always be up to the mark as one thing is the best in our arsenal tomorrow someone else is working on getting something better than the best. There's no doubt about the fact that F22 or Pak-FA/FGFA will be the best for future at least the next 2 to 3 decads as after that I don't think that even manned aircrfts will be necessary. For the next few decades all the air forces around the world will be based mostly on the 4.5 gen fighter aircrafts. F22 has a rarest kind of stealth features and has been originated in US which has been soundly very capable of produsing and taking warfare to a different dimention altogether... Russia on the other hand was always a step ahead of the Us in terms of military warfare but after the fall of USSR the race almost ended due to the lack of funds and now they are getting back on their feet very fast.
When it comes to the comparision of these two aircrafts there is no doubt that it will be a tough evaluation on top of that there is no way that these two fighters will be facing each other ever in the near future or maybe never. Only if US goes on against Russia or the opposite. In terms of weapons F22 and Pak-FA/FGFA can carry the same ammount. It's the verity of the weapons that's gonna be important. Though PAK-FA is still in infant stages of testing but Im sure that it will come up with a lethal puch when it's ready for use. It has a total of 16 hard points comepared to that of 14 of the Raptor. In stealth mode Raptor can carry 2 AIM-9M/X and 6 AIM-120C for Air to Air**In Air to Ground mode it will be carrying: 2 AIM-9M/X, 2 AIM-120C and, 2 1000-lb JDAM or a combination of 8 250lb SDB, 2 AIM 9M/X and, 2 AIM 120C. Where as in No Stealth mode 2 AIM 9MX, 6 AIM 120C, 2 Fuel Tanks 600 GAL each and 4 Missiles (Varied) WHEREAS PAK-FA has no updates yet as to what will be it's armament but for sure it will be something deadly as well.
Although there is no reliable information about the PAK FA and FGFA specifications yet, it is known from interviews with people in the Russian Air Force that it will be stealthy, have the ability to supercruise, be outfitted with the next generation of air-to-air, air-to-surface, and air-to-ship missiles, and incorporate an AESA radar. The FGFA will use on her first flights 2 Saturn 117S engines (about 14.5 ton thrust each). The 117S is an advanced version of the AL-31F, but built with the experience gained in the AL-41F program. The AL-41F powered the Mikoyan MFI fighter (Mikoyan Project 1.44). Later versions of the PAK FA will use a completely new engine (17.5 ton thrust each), developed by NPO Saturn or FGUP MMPP Salyut.
Three Russian companies will compete to provide the engines with the final version to be delivered in 2015-2016.
When it comes to The Avionics package The PAK-FA SH121 radar complex includes three X-Band AESA radars located on the front and sides of the aircraft. These will be accompanied by L-Band radars on the wing leading edges.L-Band radars are proven to have increased effectiveness against VLO targets which are optimized only against X-Band frequencies, but their longer wavelengths reduce their resolution.
The PAK-FA will feature an IRST optical/IR search and tracking system.
Sukhoi recently demonstrated cockpit mock-ups, which may relate to both Su-35 or PAK-FA, suggest two very large MFDs and a very wide HUD
Hindustan Aeronautics Limited will reportedly provide the navigation system and the mission computer.
Whereas the F-22's avionics include BAE Systems E&IS radar warning receiver (RWR) AN/ALR-94, AN/AAR 56 Infra-Red and Ultra-Violet MAWS (Missile Approach Warning System) and the Northrop Grumman AN/APG-77 Active Electronically Scanned Array (AESA) radar. The AN/APG-77 has both long-range target acquisition and low probability of interception of its own signals by enemy aircraft.
The AN/ALR-94 is a passive receiver system capable of detecting the radar signals in the environment. Composed of more than 30 antennas smoothly blended into the wings and fuselage that provide all around coverage plus azimuth and elevation information in the forward sector, it is described by Tom Burbage, the former head of the F-22 program at Lockheed Martin, as "the most technically complex piece of equipment on the aircraft." With greater range (250+ nmi) than the radar, it enables the F-22 to limit its own radar emission to preserve its stealth. As a target approaches, the receiver can cue the AN/APG-77 radar to track the target with a narrow beam, which can be as focused down to 2° by 2° in azimuth and elevation.
The AN/APG-77 AESA radar, designed for air superiority and strike operations, features a low-observable, active-aperture, electronically-scanned array that can track multiple targets in any weather. The AN/APG-77 changes frequencies more than 1,000 times per second to reduce the chance of being intercepted. The radar can also focus its emissions to overload enemy sensors, giving the aircraft an electronic-attack capability.
The thurst to weight ratio of PAK-FA/FGFA is 1.4 and for F22 it's 1.08 that means better maneuverability for PAK-FA and better angle of attack. The Raptor has Pitch Thrust vectoring that means 2D movement only up and down but PAK-FA or FGFA has complete 3D thurst vectoring giving it an edge over the Raptor here. But The Moskovsky Komsomolets reported that the T-50 has been designed to be more maneuverable than the F-22 Raptor at the cost of making it less stealthy than the F-22.
Plus PAK-FA/FGFA can handle +11Gs and most possibly -4 or -5Gs whereas raptor can manage with max +9Gs meaning again less agile....
That's the most I could come up with with help from the Wiki... lols....
