Well .......
.
The F117A is not the fastest fighter around - not in the league of the faster fighters (F14, 15, etc) ..... but it is still a fighter ......
.
I don't believe it can carry enough ammo (armament ?) or has the range to be considered a bomber .....
.
(I'm certainly not an expert in this area - but I did stay at a Holiday Inn one night)
.
The A10 ... (one of my faves) ...... Thunderbolt/Warthog ... whatever ..... is a considered a fighter - and it can not fly at supersonic speeds ....
