I missed that.

This thing will never weigh more than 13T.

The Flanker normally operates with less than half fuel because most of the time it does not need its max flight range, and I suspect that this aircraft will never carry full fuel and full weapons.
Based on the size of the weapon bays I am not sure it could even carry more than 7 tons of ordinance anyway.
The main weapon bay is similar to one of the bays on the Su-57, so we are talking about two weapons like R-37Ms or Kh-59 Anti radiation missiles, and the two forward weapon bays look like they might carry one R-77M each... so that would be less than 2 tons...
That means assuming a max TOW of 16 tons, where 7 tons are weapons that means when it is carrying full fuel and everything else but 2 tons of air to air missiles perhaps, it will have a take off weight of 11 tons and very low drag.... but then it likely wont be operating with full fuel either... which will make it even lighter.

The 18 t TOW stated can be a NTOW under certain, not clearly named circumstances, which is unsurprising, since empty weight is a figure the Russians hardly ever provide publicly. I assume the plane is a little lighter than it may seem due to its size, because of statements regarding its TWR being in line with the best and because of the 8 g rated airframe. A weight of max 10-11 t empty seems needed to match the TWR of the F-35A, depending on the engine that is finally used. With the izd. 30, the weight of the airframe could raise notably and/or the TWR would improve

It is a light fighter, ability to point the nose and reasonable acceleration is all it really needs.

Checkmate still has a chance in UAE it seems.

The UAE has told U.S. officials it intends to pull out of a $23 billion F-35 and drone deal because "security requirements the U.S. had laid out to safeguard the high-tech weaponry from Chinese espionage were too onerous."

If true, that is going to cause a collective mental breakdown among Western fanboys that had betted their asses that the whole reason for the LTS project was UAE using Sukhoi as leverage to get their hands on the F-35. Yes, I am not joking, they said actually that

S75 is perfect for J16 and J20 to hide behind when they patrol near japan. Think Chinese air force only comes out when Russians are in the air. Or that might be the navy?

Both. The chinese navigation equipment seems to be rather limited in it´s capabilities.

Don't think he is Chicom - he gave himself away with the 18 aircraft in a squadron.
I have no problem at all with Bob but Bollusc does have a funny ring to it.

https://eadaily.com/ru/news/2021/12/21/bespilotnaya-modifikaciya-su-75-chto-ostalos-za-kadrom-na-dubai-airshow-2021
After the announcement of the concept of a light multifunctional fighter of the 5th generation Su-75 Checkmate on the fields of the International Aviation and Space Salon MAKS-2021, no more than six months have passed, and now at the Dubai Airshow 2021, UAC Ceo Yuri Slyusar announced the upcoming development of an unmanned modification of a promising single-engine machine.
Without going into details of future R&D in the framework of the Su-75 design, as well as detailing the alleged operational and tactical advantages of the advanced platform, the head of the United Aircraft Corporation, a member of Rostec, spoke about the ability of the new "drying" to implement "new tactical techniques within the framework of network-centric military operations."
Such a superficial description of the potential of the ambitious 5th generation unmanned platform from Sukhoi Company PJSC, designed to complement the unique abilities of the Su-57 - Okhotnik-B tandem, serves as an incentive for experts to conduct their own analysis of the visible tactical, technical and operational-tactical advantages of the advanced concept.
First of all, this is equipping the Su-75 combat aircraft with completely interchangeable with the multi-purpose fighters of the transitional generation Su-30SM1/2, Su-35S and their twin-engine "older brothers" Su-57 turbojet double-circuit afterburner engines AL-41F-1 / F-1S, or their more "thrust" version of the second stage "Product 30". This will provide the possibility of prompt maintenance and repair (including replacement of nozzle modules, afterburners, low-pressure turbines, fans and other critical elements) directly at jump airfields and air bases of the future deployment of any su-35S machines.
ADVERTISEMENT
Such a high level of flexibility in servicing the AL-41F-1 / F-1S family is due to both the interchangeability of their key structural units and the modular architecture of the construction of the latter. This modularity, in turn, was embodied "in the iron" of the early modification of the AL-31F turbofan engine, which passed state bench and flight tests in the late 1970s and was installed on Su-27 / SM, Su-30M2, etc. interceptor fighters.
Possessing afterburner thrust of 15,000 and 18,000 kgf, respectively, as well as having systems of all-angle deviation of the thrust vector with an angular velocity of displacement of nozzles of 60 degrees / s, the AL-41F-1 and "Product 30" engines are able to provide the Combat Su-75 in the unmanned modification with a thrust-to-weight ratio of 1.0 - 1.06 kgf / kg (depending on the mass of the fuel residue and ammunition). When making turns in a vertical plane ("vertical carousel"), such a thrust-to-weight ratio in conjunction with a triangular wing of a large area makes it possible to achieve an angular velocity of the established turn of the order of 25 degrees / s with only a slight loss of speed. At the same time, the high afterburner thrust on the midships provides the Su-75 with excellent acceleration qualities, accelerating the machine from 600 to 1,200 km / h in just 12-15 seconds.
And this is not to mention the huge list of super-maneuverable aerobatic figures (from the Pugachev Cobra to the Frolov Chakra), performed thanks to the all-angle OVT system and providing the Su-75 with the opportunity to establish dominance in close air battles ("dog dumps") over the American multi-purpose fighters of the 5th generation of the F-35A / B / C Lightning II family. ultra-maneuverable short-range air-to-air missiles R-74M (RVV-MD), equipped with interceptor systems for deflecting the thrust vector. These systems, coupled with modern wide-angle dual-band infrared seekers, endow the R-74M missiles with truly the highest flight performance, up to the interception of highly maneuverable air objects in the rear hemisphere of the carrier aircraft.
As the second significant "trump card" of the unmanned modification of the Su-75, the impressive released (previously inhabited) volume of the cockpit can be considered. This space can be used, firstly, to accommodate an additional fuel tank with a volume of more than 1,000 liters, which will increase the total volume of the fuel system from 6,000 to 7,000 liters. the Implementation of such a solution will increase the range of the fighter from 1,350 to 1,650 km, which is 65-70% higher than the performance of multifunctional fighters of the 5th generation F-35A / B.
The unregulated "framing" air intake of the Su-75, although it limits the maximum speed to 1900 km / h, does not affect the combat potential. Illustration: discover24.ru
Secondly, modular racks of various configurations can be integrated into this released intra-fuselage volume to accommodate numerous hardware units and terminals with BCVM, which control the on-board complexes of radar, electronic and electronic reconnaissance, electronic warfare, as well as the exchange of tactical information with the "leader" of the Su-57, or other air gearboxes. For example, in this volume can be placed an additional high-energy installation based on the turbogenerator of the incoming air flow, as well as a powerful ultra-high-frequency klystron / magnetron powered by this turbogenerator, which transmits the modulating signal and the carrier frequency to the antenna canvas of radio counteraction. Thus, unmanned "Screamers" (NATO codification of su-75: Screamer - "Screamer") in the future can become one of the most advanced air platforms of electronic warfare of the third and fourth decades of the XXI century.
And of course, unmanned versions of the Su-75 will be able to function in the "unmanned wingman" mode, using protected two-way asynchronous data exchange and telemetry lines identical to those used to establish network-centric communication between the manned Su-57 and the S-70 Okhotnik-B strike reconnaissance UAVs.

Nato being nato they'll call it something patheticly insulting like Felcher or Failure.
Who TF even gives a shit about nato naming anyway now that Russia openly gives the names?

Fischer in ref to Bobby Fischer who was a chess champions. But at the end he hated the US and turned against them so unlikely. I guess russia should name it that.
