The Wing-SV will be actively worked on in this model and in the requirements in the next year, and, according to the results of SibNIA, a real automatic landing of the developed prototype of this stage should eventually take place.
It should be noted here that at the FPI a preliminary design of the winged stage with the name “Wing-SV” was ready in the spring of 2019, after which it was finalized at the Myasishchev Design Bureau – when the height is increased, the specified project provides for the inclusion of the stage wing itself, as well as turning off engine, after which the “Wing-SV” must return and carry out automatic landing.
