Mission accomplished. The previously published ceiling of the F-22 was 50K feet. The Pentagon said it (edit: by "it" I mean the F-22) was flying at 58K feet when it shot down the first balloon. Guess it can do (at least) 58K.
This was probably not entirely groundbreaking news to anybody including China. Everybody knows that the published specs of military hardware are intentionally distorted in one direction or another.
The F-15's known ceiling is 65K feet for example. So it's not surprising that newer fighters can match that.
There's not really any reason the Pentagon needed to state the F-22 was at 58k if that was actually new information (I haven't investigated the previously admitted service ceiling). They could have just as easily have claimed it was at 50k when it fired.
EDIT: Wikipedia claims the service ceiling of the F-22 is 65k feet anyways.
