"At the moment, with the allocation of the necessary funding, the Khrunichev Center plans to begin flight tests of the KVTK upper stage in 2027," RIA Novosti quoted Kuznetsov as saying.

It is noted that the KVTK is planned to be used on Angara-A5M and Angara-A5V heavy-class missiles.

On October 3, the head of Roscosmos, Dmitry Rogozin, announced that the Omsk site of the Khrunichev Center would begin to produce at least four Angara heavy rockets from 2023.
