As a method of generating artifical gravity my rockets use centrifuges. KH has two of them, spinning in opposite directions to compensate each other torque,

Rockets with R-layer drive use much energy. This requires big radiators to remove excess heat from generators,

Two-way classic engines: Rockets big enough would have problem with rotating whole rocket just to accelerate/deaccelerate so their engine section has nozzles facing both front and rear end of the rocket

And last but not least: R-layer drive. Rockets with them are simply a big long engine "surrounded" from each side with stuffs: generators, habbitats, weapons etc.
