I've been refining a general rocket launch simulation program over the last few years, modeling it on the work described here by Robert Braeunig. According to my current version of the simulation, it's possible to launch 134,000kg of payload (including fairing mass) to a 185 km x 200 km orbit at 28.5º inclination on the INT-21, in addition to the nearly-...


In general, heavier launchers can send more mass to LEO, but as described in this QA, the correlation isn't very strong. Different engine technologies used in modern rockets have different mass/impulse/cost tradeoffs. One particular example is Delta IV Heavy versus Ariane 5. Delta IV Heavy is 733 tons on the pad, 28 tons to LEO, for a payload mass ratio ...
