Bob was a weights engineer on the Shuttle Carrier Aircraft project here at Boeing (we modified a used 747 to carry the Space Shuttle orbiters). The answer is "the same as any other 747... 580,000 to 780,000 lbs, depending on fuel load". Since the Orbiters weigh about 180,000 lbs, and the airplane plus Orbiter combination has lots of drag, the range of the SCA is down around 1000-2000 miles.
