According to wikipedia, for currently operational
vehicles:
Vehicle/tonnes to LEO
Shuttle/24.4
Delta IV Heavy/22.9
Delta IV heavy is 22.5 metric tons to 51.6 degree LEO, 21.5 metric tons to 90 degree LEO,
10.75 metric tons to GTO (1500 m/s to GEO) or 12.5 metric tons to GTO (1800 m/s to GEO).
STS is 24.4 metric tons to 28.5 degree LEO, 12.5 metric tons to 90 degree LEO, 2.27 tons
to GEO.
Compared to the big boys of the EELV family the STS is a wimp, largely because it's so
damn massive in terms of dead weight.
