dark sidius said:Byeman you think its impossible to put a X-37 like spacecraft on a reusable first stage, instead of an expendable launcher?
No, I didn't say it was impossible, it can be done, if you want to only launch into the ocean and not orbit.
Again, X-37 is spacecraft and not part launch vehicle and it only has delta V for orbit changes.
X-37 is not equivilent to the space shuttle orbiter. It does not have engines for ascent into orbit.
