The F-117A is built mostly of aluminum and some titanium. The flat angles, or facets, help hide the aircraft from radar by reflecting the signal everywhere except back to the radar transmitter/receiver.
To aid in it is invisibility the Stealth is covered with Radar Absorbent Material (RAM) which is the matte black finish you see.
The F-117A is powered by two General Electric F404-GE-F1D2 engines with 12,000 pounds of thrust each which carries it to an estimated top speed of Mach.0.92. It carries all weapons internally, the most often used being the GBU-27A Paveway III laser-guided bombs.
