- Actually, this isn't a very sound argument. The US has been putting big
- bucks into small improvements to the performance and reliability of 50s-
- vintage expendable launchers. It *hasn't* made any serious effort to
- build a cheaper one (which cannot be done without changing the way the
- launchers are built and operated -- it's not the fuels and metals that
- cost all that money, but the way they're used). All that money has been
- going into squeezing one more ounce out of existing designs, and any sane
- engineer will predict a lousy cost/benefit ratio for that approach.
-
- No conclusion can be drawn about the possibility of cheaper expendables;
- it has not been tried. Even the projects that have officially included
- "lower costs" in their objectives have always had higher-priority objectives
- (typically, maximum payload and maximum reliability) that pushed them
- toward higher, not lower, costs.
-
- Certainly, even after you get past complications like different accounting
- systems, there is no possible doubt that launchers like Soyuz and Long
- March really are substantially cheaper to run than Atlas or Delta. It
- *can* be done.
