pak fa multi role ler... f-22 air superiority... mana boleh menang...f-35 mayb la
PAK FA dibina khas untuk lawan kedua-duanya sekali F-22 dan F-35.. F35 lagi teruk kena kalau mau lawan SUKHOI PAK FA!
aku rasa kelebihan terbesar dia ialah pada sistem enjin dia tu.. Russia buat SU37 sebab nak test sistem enjin yang akan dipakai pada projek PAK FA, manakala sistem aerodinamik pula dari projek Mikoyan Project 1.44 + SUKHOI Berkut 47.. sistem avionik pula dia upgrade berperingkat-peringkat test dari SUKHOI SU30 MKI yang India pakai tu kepada SUKHOI SU35 yang Tentera Udara Russia pakai sekarang dan juga, test sistem avionik terbaik dari seluruh dunia pada jet SUKHOI SU30 MKM yang Malaysia guna sekarang ni (gila punya TUDM.. p minta letak sistem avionik gila2 punya).. maunya harga jet tu rasanya yang termahal antara semua variasi SUKHOI untuk export.
expert kata SUKHOI PAK FA akan menang dengan F22.. ini review dia aku cuba quote kan untuk kita semua baca..
sistem persenjataan PAK FA, review dari airforce expert
"Consider a QWIP technology “OLS-50M” installed in the PAK-FA. Such a device could be design-optimised for simultaneous detection and tracking of aircraft exhausts, jet-plumes and missile flares to ranges of 70 nm and beyond – the limiting factors are the size of the optics, cooling system and detector area. Russia has decades of experience in the integration of infrared sensors into its weapons systems, and QWIPs could well become the primary sensor and radar the secondary. This means that the F-22A AN/ALR-94 will be denied signals to detect and track the PAK-FA.
The ‘shooting match’ shifts from radar-centric to ‘infrared centric’. The problem here is that the PAK-FA will have it, the F-22A does not, and the ability of the F-35 EOTS and DAS to make long range aircraft detections and guide weapons is at best ‘unproven’. The F-35 systems have not been designed to be highly sensitive at the task of searching and tracking distant aircraft at those infrared colours where aircraft and their jet engines emit most of their infrared energy. An understanding of the physics, or for the ever-hopeful, a simple Developmental Test and Evaluation exercise will demonstrate this.
With the Beyond-Visual-Range (BVR) radar detections being reduced to distances below 60 nautical miles and infrared sensor detection ranges growing beyond 50 nautical miles, a new generation of missiles will be required to dominate the battlespace.
Russian missile companies have shown much more flexibility and adaptability in the design of missiles, so the PAK-FA could have a new-generation of shorter range, but higher agility missiles – a fusion of the ideas in the R-74 and R-77M, with a diverse mix of seeker heads. These missiles will likely be cued by the IRST sensor, be equipped with inertial midcourse guidance and, probably, mid-course guidance update capability transmitted either by radio, or possibly infra-red laser or millimetric wave links.
Expect the PAK-FA to have vectored thrust and high levels of agility like the Flankers it is to either replace or complement. Long missile range requires large rocket or ram-jet motors and these heavy weapons lack the agility to pull high terminal ‘G’, and may be ‘ducked’ by the PAK-FA as easily as by the Su-35-1. "

"The PAK-FA will use a new super-cruising engine, based on technology from the Al-41F series, so its tactic might be to maintain combat speeds of about Mach 1.5 and use a more compact version of the ramjet RVV-AE-PD. A supersonic launch enables a ramjet to light without a powerful booster – thereby denying an opponent the detection of the usual missile launch flare."
ramalan situasi sebenar peperangan SUKHOI PAK FA vs F22 vs F35
"Fights between the F-22A and the PAK-FA will be close, high, fast and lethal. The F-22A may get ‘first look’ with the APG-77, the Advanced Infra Red Search and Track (AIRST) sensor having been deleted to save money, but the PAK-FA may get ‘first look’ using its advanced infrared sensor. Then, the engagement becomes a supersonic equivalent of the Battle of Britain or air combat over North Korea. The outcome will be difficult to predict as it will depend a lot on the combat skills of the pilots and the capabilities of the missiles for end-game kills. There is no guarantee that the F-22 will prevail every time.
The fate of the F-35 Lightning II would be far worse in an air combat environment challenged by the PAK-FA. If the Mach 1.5 PAK-FA is using its infrared sensor as the primary sensor and observes radio frequency emission control (EMCON), then the first detection by the F-35’s APG-81 radar could be at ~20 nautical miles or less with a missile launched by the PAK-FA’s infrared sensors already inbound from 60 to 70 nautical miles away. The PAK-FA could easily break to a direction outside the F-35’s AIM-120 engagement zone.
The sustained turning performance of the F-35A Lightning II was recently disclosed as 4.95 G at Mach 0.8 and 15,000 ft. A 1969 F-4E Phantom II could sustain 5.5 Gs at 0.8 Mach with 40 percent internal fuel at 20,000 feet. The F-35 is also much slower than the 1960s F-4E or F-105D. So the F-35A’s aerodynamic performance is ‘retrograde’ when compared with 1960s legacy fighters. The consequence of such inferior JSF performance is that its DAS might detect an incoming missile, but the aircraft lacks the turn-rate to out-fly it. As the F-35 also lacks the performance to engage or escape, repeated ‘freebie’ shots from the PAK-FA could inflict high losses. Expect the exchange rate to be of the order of 4:1 in favour of the PAK-FA, possibly much higher
The most dangerous situation the US could face, is where the high and upwardly spiralling development and production costs of the JSF ‘cuckoo’ the available resources, which are needed to develop the advanced capabilities necessary to counter the new Russian PAK-FA, and the generation of new weapons which the PAK-FA will inevitably be armed with.
Complacency is not an option. Having ruled the roost for the decade out to 2015, the F-22A may be knocked off its perch by a newcomer, unless the US invests in new sensors, especially, and advanced technology Infra-Red Search and Track, stealth improvements and a new generation of missiles for the F-22 – assuming it even builds more than the token number of F-22s currently planned. The F-35 has already been neutralised and negated by the Su-35-1/35BM and will be substantively overmatched by the PAK-FA. The West needs to think long, hard and fast about the PAK-FA, as the current and retrograde “F-35 centric” future fighter fleet model guarantees certain defeat in future combat."
diaorang kata kalau nak lawan sebijik SUKHOI PAK FA kena guna kaedah NETWORK CENTRIC WARFARE yang diaorang pernah cuba aplikasikan dalam peperangan di Iraq dan Afghanistan.. tapi aku rasa negara Cina, ally kuat Russia mesti kongsi maklumat risikan yang diaorang dapat hack dari PENTAGON tu.
