On July 21, 2014, the Russian president Vladimir Putin paid a visit to the city of Samara, south of Moscow, which included a stop at RKTs Progress, the manufacturer of the Soyuz family of rockets. The company was also vying for the leading role in the development of the future super-heavy rocket with its proposals for the STK series. Seven weeks later, on Sept. 2, 2014, during Putin's visit to Vostochny, his Vice Prime Minister Dmitry Rogozin told journalists that the president had given his "preliminary approval to start the work on the super-heavy launcher." At the same time, the head of the Russian space agency, Roskosmos, Oleg Ostapenko proposed to channel the money that had originally been allocated to build backup launch pads for the Angara rocket in Plesetsk and in Vostochny into the super-heavy launcher program. Ostapenko has been known for his sharply negative attitude toward the Angara rocket as too small for the future needs of the Russian space program. If approved, the plan would leave Angara with a single launch pad at each of two launch sites. - RSW
It doesn't mention the A7 pads, but the so-called "backup ones" might (?) be able to launch it.
