The Russians have the best liquid fueled rocket motor designs in the
world. That was brought home to me, reading about L-M's experience using
Russian RD-180 engines in the new Atlas V.

The schedule for booster integration and checkout includes lots of time
for chasing leaks in the pipes between tankage and engines. L-M's people
put those steps into the Atlas V's schedule. The Russians said "what
leaks? Build the piping to our Interface Drawings and it won't leak." Sure
enough, L-M built to print and no leaks were found.

You can count the number of centerline rocket motor designs done in the
West with your fingers. The Russians have done many more and the
production volumes were lots higher, since Soviet spacecraft had short
mission lives. In consequence, the Russian (and Ukrainian) designers
learned to take the drama out of high performance turbo machinery and
liquid engines.
