- at the bottom of Blok A, below the lox tank, there's another hemispherical shape that goes below the engines. Some kind of heat protection wall for the plumbing?

- the roll control engines appear to have been moved below the vehicle, between the inner and middle engines. You can see them as dots in the aft view, and there appears to be a prop line going there in the side view
- the grid fin configuration can't control roll, which is maybe why fins show up
