Karma,
Yes there is a SP Campaign. Several in fact. I guess the best way to describe it is scripted to a point, with random/un-scripted elements and triggers built into each mission. You fly the missions and try to accomplish the objectives and you can advance in rank and win awards and commendations.
Other flights appear and proceed with their missions of course and you act accordingly.
I don't remember what RB2's campaign was like so I can't compare.
