This may have been true in the 1960s but is definitely no longer.

Usually the LOx plant is built at the test/launch site. At RPL at Edwards AFB
during the F-1 testing days there was a LOx plant on site, the building is
still standing, just before you get to the high thrust area, stands

Hi Bill,
Is there a significant cost to get it from the tanker into the rocket? A few
years ago, I was given a tour of the new SLV, LOX/Methane launcher facility
at KSC by NASA and Space Florida. It didn’t appear to be trivial.

My source was for tank car quantities delivered at KSC.

Where are these propellant prices? At the plant or loaded into the rocket?

Henry:
RP-1 was $0.379 / lbm.; LH2 $1.774 / lbm. and Lox $0.088 / lbm.
Assumed mixture ratios were 2.4:1 and 6:1.
Because Lox appears to be a true commodity (it’s price is mostly the cost‘s
of business, the direct cost being tied to the cost of electricity) and
because it is the dominate cost for propellant, it does not appear—to
me—likely that these numbers will change much in real terms.
Indeed, because the cost of hydrogen appears likely to increase when (in the
fullness of time) the supply of natural gas runs out, my own guess would be
that the real cost of propellant will very slightly increase over the very
long run.

What were the LOX and RP-1 prices individually, and what mixture ratio was
assumed? (Today's mixture ratios don't necessarily yield the lowest
possible cost for a chemical rocket.)
