It's so much simpler! And with the improved density you could fit over three thousand tons of hypergolic propellant into a shuttle external tank while shaving off over two tons of dangerous and unnecessary foam insulation.

Sure, go for it.

It'll be fun.

The engineers who made and tested this must've been fearless.

The testing engineers must've been fearless, or suicidal.

>The RD-270 was the Soviet Union's answer to the American F-1. It generated the same thrust with about 40 seconds more Specific Impulse. However the engine's immense size gave it explosive combustion instabilities like that on the F-1, however the Soviets were never able to solve the problems
>The engine was fueled by N2O4/UDMH, and used a high temperature full flow staged combustion turbo-pump assembly. A highly experimental system.
>It was reported that the technician closest to the engine during test fires lost over five pounds in nervous sweat alone.

The RD-270 was the Soviet Union's equivalent to the American F-1, except it is propelled by N2O4/UDMH and uses a balanced closed cycle pump system somewhat similar to the Raptor.
