It's a little more complicated than that, given that the B-2 has been IOC for quite a while but wasn't used in that op.
The B-2 was used over Yugoslavia. It was a B-2 that bombed the Chinese Embassy in Belgrade.

The Serbs even claimed to have shot one down!
Lt. Col. Djordje Anicic, of the 250th Missile Brigade still thinks that he shot down B-2 Spirit of Missouri, serial 88-0329, and that it crashed and was covered up by NATO.
Lt. Col. Djordje Anicic in interview.
Of course Spirit of Missouri is still operational and the only B-2 lost (Spirit of Kansas) was due to a crash in Guam.
