Admiral gorshkov, ex Baku, had at least a better fate as it was preserved and later converted by Sevmash into a STOVL carrier for India.
STOCL... short takeoff (from a ramp) and conventional landing (hook and arrester cables).
So I do not imagine a carrier borne derivative of the Su-75 Checkmate. Much more probable would be something derived from the Su-57 (or a modernised version of the Mig-29k)
Both MiG and Sukhoi have been burned in the past making single engined aircraft and being told that is not acceptable by the Russian AF. MiG had an F-16 like single engined fighter as an alternative to the MiG-29 which was rejected because it was single engined, Sukhoi had a jet LIFT that was also rejected because it was single engined too... about the only planes they will accept are the Yak-52/152 trainers and the An-2 and its single engined replacement Baikal aircraft.
The problem now is not that the sanctions against russian companies prevent them to obtain parts and equipment, but that US is putting pressure on third countries and blackmailing them in order not to buy russian military products.
It is actually a good thing... as they keep bullying countries like that more and more are going to find they have to say no more and more often and it gets easier over time. If the US cancels aide they quickly learn they end up saving money because US Aide can only be spent on expensive and largely useless US weapons anyway so it really does not contribute much to defence and often ends up sucking up more funds for expensive maintenance and support.
Carrier or no carrier, the GoMiGman wants to see this thing FLYING, and FLYING VERY SOON, and FLYING CIRCLES around anything it encounters and forget about finding some Arab Sheikh from the UAE or Saudiya or Qatar or even prince Henry himself to finance it. Let's get it going, fellas, LET'S GOOOOOOOO!!!
This is just fan art though,,, there is no way it could have those two engines using the same tiny air intakes... adding that extra engine would require much much bigger air intakes to work.
A dorsal air scoop that operates in VSTOL mode that opens when the aircraft is taking off or transitions to the hover might work, but it is clearly not there so I say this is fanart.
The Su-75 is more and more reminiscent of the Su-57, but I would install two engines.
Yes, the price of the plane would be higher, but it would be worth it.
With two engines it would be an Su-57. The whole point of the Su-75 is to reduce weight and power and to simplify and make affordable.
I cannot be impressed by an aircraft that has worse flight performance than the fourth generation aircraft.
The F-18 has shorter range and less payload and is much slower than an F-14. In terms of electronics it is much more advanced but nothing that couldn't be put into an F-14 to improve it too.
The key thing the Su-75 has over 4th like Rafale and Gripen and Typhoon is internal weapons carriage and it is actually stealthy.
Supermanouverabilty comes from thrust vectoring engine, not excess thrust to weight ratio... that determines acceleration along with weight and drag of course.
The Chinese agree, their F-35 copy has two engines and the MiG-35 has two engines too... but some people think you can't have a cheap affordable plane with two engines. Ignoring that the MiG-35 is cheaper than the F-16 to operate and of course the F-5 was cheaper than the F-16 too, or the F-20 with two small reliable cheap engines replaced by a bigger much more powerful single engine that was not cheap to buy or maintain didn't make it a cheap plane anymore.
A plane that can get into and out of the zone of action faster will always be a better plane.
Fast planes can be shot down too.
Stealth makes it harder to find you and to track you but it is not magical.
Most Russian air defence systems have backup modes that allow optical engagement, but most of the time being stealthy would be useful if not critical.
If you can get a light stealth fighter for $40 million and its maintenance costs are less than $8K per hour of flight then you have a real winner.
Since it is expensive because PAK-DP will surely get much more money, then the Su-75 is only an airplane according to the principle of "give what you already have".
There is no evidence that the Russian government is putting any money at all into Checkmate. There was talk that they promised MiG funding for the LMFS programme to make a cheap light 5th gen fighter once the Su-57 is in serial production... which it is now, but they have not said anything about that... and they are not obliged to.
I suspect they wont say anything about that because that might sabotage the Su-75 programme to use technology from the Su-57 to make a single seater light single engined fighter and sell internationally.
The Russian government might not be funding either programme, but then MiG would be publicising their model and trying to get it built and tested... the fact that they are not suggests to me it is funded but is secret.... the same way the Mi-28A attack helicopter was shown in the west in the late 80s and early 90s to find export customers after it lost the competition against the Ka-50 to replace the Hind in Russian service. Of course after Desert Storm they realised helicopters were safer operating at night and a single seat Ka-50 was at a disadvantage because flying at night is a full time job so having two crew makes sense so they anulled the results and ran it again with the Ka-52 and Mi-28 and decided to use both because the Ka-52 was too expensive to replace all the Hinds and the Havoc was actually a good helicopter too.
