They can certainly land them but it doesn't have the take off length needed for a combat load. If they take off vertically they have to trade fuel for weapons.
True, sir, my point was : Mistral can use V/STOL was not designed to have own fixed wing though. BTW STOL take off distance for F-35B is not 400feet (i.e. 120m)?

Because nobody in the world want the costs and techical complexities of a STOVL aircraft if it has to be employed from land.
The british and US Marine have been and still are the only in the world operating STOVL aircrafts on land bases.
Nobody else does it, period.
Italians should be before your period ok? Tjhis is not about complexity but about price. Russians can go for more economical design because not all features have to be on the same level. Soviet Union pertty much interested in usage of light STOL fighters.

For a STOVL aircraft the airframe has to be purpose built, the JSF born day one with the requirement for a STOVL version, so because Su-57 did not born with a requirement for a STOVL version, the airframe of any hypothetical STOVL aircraft will have to be purposedly designed. Yak-141 is so old on any possible technological aspect that could not be of any use as well.
By the way, it has to be expected some LO requirement for the aiframe to fulfill, too.
The engine will have to be designed almost from scratch as well, and to follow the whole test and certification procedure of any new engine, along with related time and costs.
Avionic will have to be closely adapted to the airframe, its specific internal space arrangement, cooling capabilities, electric power generation and so on.
Su-57 is large, IMHO way to large for any fleet adaptation. Indeed you need to adaption of parameters but it is a bit less expensive in term or resources. And yes re-building Yak-141 in current form makes absolutely no sense.
BTW Boeing X-32 kind of plane looks cute to me though
