Can the NASA Shuttle be classified as a disruptive technology? If so, Why?

I would say not.  Other countries don't use it.  The fact is, we fall
back on rocket launchings sometimes when the shuttle is not available.
 Sometimes rocket launchings of other countries.  No other country
seems to be adopting shuttles for launch.  Other countries are gaining
larger and larger percentages of launches for commercial satellites
atop their rockets.

Also, our own military was smart enough not to become dependent on
shuttle launchings for its spy satellites.

Firstly the russians also have shuttles and the chinese are working on them. 

secondly nobody is going to launch a missle into space while a shuttle
containing people is in its way so missles and shuttles are disruptive
to each other.

Yes shuttles are disruptive however due to the expense of launching
things into space they are usually done in batch lots infrequently so
dont actually cause disruption.
