Ah! Room for a tech angle here?

Korolev and von Braun made a rocket engine the same way? Not bloody likely.

Actually von Braun (via Rocketdyne) were able to solve the combustion instability problems of large-nozzle engines but Korolev (via Glushko) never did, hence the difference in design philosophy (they used multiple small nozzles, which made for reliability problems).

On the other hand the Russians pioneered bleeding off some exhaust to power pump turbines (a so called 'staged combustion cycle') which meant another 15%, a sheer efficiency gain.

So there!
