That question was definitly no longer valid as of
October 4, 2004
space shuttle is no longer true.
its valid, but there are now 2 (actually 4 but read on)
spaceshipone is the second and owned by a private company
http://www.scaled.com/projects/tierone/041004_spaceshipone_x-prize_flight_2.html
it is US funded, designed and flown.
It has not been used as much as the shuttle, and neither are flown or in orbit at this moment.
It's version 2, spaceship 2 WILL be in air shortly on a daily basis (but it doesn't count yet)

The ISS is not US property, so even though there are Americans on board its not technically a US manned craft.
The only other US craft that enters "space" is the space shuttle, but there isn't one in orbit at this time.
So the answer is none.

If you mean right this minute; zero.
The international space station has americans on board right now, but it's not a US spacecraft, technically.
The space shuttle is the only truly american manned space craft in use at this time.

The space shuttle and the jointly manned space station.

I guess that would be the Space Shuttle.
