Angara 5? (One center core, 4 side boosters. Not clear if doing propellant cross feed). Angara 7? New much larger center core, 7 side boosters?

Other things that have been called Angara over the last decade or so of its development.

Or maybe just a simple Angara 3?

Each Angara core is using an RD-191 engine, which is 1/4 of a RD-170 (RD-180 of Atlas V fame is 1/2 an RD-170). So around 400-500Klbs of thrust. A single core is just not that powerful.

Two cores just bring it into the range of lift thrust that Atlas V already has.
