Everyone has their own definition of 5th gen such as one having preference for 360 degree radar coverage over midwave, short wave infrared coverage. Some 5th gens have a preference for a secondary sensor long wave infrared target detection.It's not a matter of hate or love, or anything to do with preference. I must first question if you know what actually means to be 5th gen in the first place. As we all know, building a 5th generation aircraft doesn't simply mean getting some edges aligned and add an internal weapons bay. What's crucial would be integration of every avionics and achieving higher level of sophistication.
One example would be how F-35 fuses its data from various sensor to form a unified picture of 2-sphere airspace and every traffic around it, applies that data to its CNI channel and identify those tracks from 2-sphere with its SDR radios and respond if the bogey is found to be hostile. By analyzing the level of threat, suggest its pilot the best solution, which would either be to ignore, re-route, use EW to electronically attack or directly engage with its munitions and LPI radar mode. It is also able to share this picture and data (sufficient for fire control purposes) using highly stealthy LPI data links such as those ones like MADL or simply use other JTRS like the WNW. This combined with the VLO airframe design lets this aircraft to operate as VLO. It's crucial that both sides exists as a single package.
Turkey seems to also pursue sensor fusion for the TFX according to what I am reading here so we cant say the TFX wont be able to share information https://www.defenceturkey.com/en/co...tically-with-the-turkish-fighter-project-4312. Well I honestly am a critic at some of there claims from before that were not TFX related but they seem to take sensor fusion into consideration but when to apply it there is no time frame.
Moreover, you call people out to 'hate TF-X only, when there are other fighter jet development programs going on internationally' but I haven't seen anyone apart from the Indian themselves who think AMCA to be realistic at all, for example. Apart from that, the KF-X is clearly 4.5th gen and will be 4.5th gen, Japan's plan to build 5.5th gen aircraft cannot be compared to the aforementioned examples since their technology level far exceeds any of these 3 countries. Chinese 5th generation programs are the results of their sheer amount of investment which is incomparable to that of Turkey or India. We also understand nowadays that the Russians are taking, say, a different approach to 5th generation compared to other countries.
Yeah funding is important but so are lowering maintenance costs like using fiber optics to sense wear and tear in an aircraft or trying to reduce flight costs of 44,000$. I cant determine Turkey's financial situation of what they are willing to fund other than appearing serious about building aircraft related factories or what numbers they want. Stealth as a 5th gen requirement can be improved with more breakthroughs in metamaterials, like the Russian's stating that bending radiowaves around an aircraft works better than absorption and reflecting radio waves away and China stating 1000 times lower RCS for aircrafts if applied. But I do not know where the U.S. stands between the two in this field but for a country like Turkey that might be a little difficult. Countries have different low RCS requirements which no one can determine which option is the best.
Lastly, it's not like photonic radars are something "better" than the phased array but a different kind of antenna back end. Also, first implement, then talk. If anything, I'm still more impressed with fully digital beam forming arrays that are being developed in the west right now, which is also far more technologically ambitious.
There are slight advantages that I see with AESA MMICs over PESA but the advantages of the news reports of PICs appear to be more huge that I might even go as far as stating that a 4th gen equipped with such a radar might give a 5th gen a run for its money. If you want sources for the below points I wont mind providing them to you but I do not really want to stray away from this thread.
1. Chinese stating the background noise is lowered more than 100 times, while KRET stats a Kamaz truck mounted radar would have the same kind of radar performance in finding targets as a ground building radar that is several stories high.
2. radars having EW immunity in which they state there is no such thing that can exceed 200 decibels to jam the radar, so imagine a bunch of aircrafts trying to jam the radar performance of a single aircraft that remains unaffected while that aircraft can freely jam other aircrafts.
3. Using lower waves than firecontrol has resulted in 10 times increase in RCS but a less precision in tracking but performances in firecontrol homing radar beams on air to air missiles will search where the big target is for better precision and engagement.
4. SAR resolution capabilities of seeing and recognizing human faces.
5. 100ghz would offer amazing high precision tracking capabilities and lowering the noise loss would give it a better range than what MMICs have offered with it before. The news that was received yesterday has shown that the antennas seem a little bit thicker than paint so 360 degree coverage would be perfect to create a mini-missile APS probably the size of the quadpack pantsir proposal, because I am sure the homing performance might suck based on size but what the ranges are of the 100ghz higher precision tracking being used with photonic integrated circuits might compensate for the homing capabilities of miniature APS missile to engage air to air missiles instead of just DIRCM.
6. 100s of qubits of radar data transmission claimed, that just for the fun of it I decided to find out what the data traffic of the entire UK is and apparently the radar meets or exceeds the busiest traffic hours of the entire country and lets just say I know a 6th gen aircraft with radar data transmission claims of a city's worth of data.
7. This is rather unknown but I wonder how good the EW suppression capabilities might be.
Sure their companies KRET and RTI state the they are 5-10 years behind the west in MMICs, maybe even further behind when comparing them to Japan, South Korea and Taiwan, but PICs are a different animal from MMICs.
In same sense, the DIRCM of Su-57 and the lack thereof on F-35 should be understood as what I mentioned to be the different approach to 5th generation. It's not like doom and gloom all of the sudden for the J-20 and Lightning because the Felon has one and it doesn't
Countries have a different pace in technology and some that are hard to determine such as Russia had no major drone projects and yet they surprised everyone out of nowhere with a heavy stealth drone project while giving production dates while other countries that had heavy stealth drone projects longer have not offered any production dates. Had no operational AESA but might be the 1st to equip ROFAR. Had no major laser projects like the kilowatt projects offered by other countries than all of a sudden I see megawatt laser projects from them emerging. Soviet union made the kholod project, Ufimtsev work being praised by skunkworks as a rosetta stone, operation mount hope 3, project azorian shows creativity from one country that does not invest a crazy amount of money on projects causes another richer country to be curious. I would like to see Turkey's creativity.
