Rating: 4 Yes, this is correct. The faceted shapes were due to
limited computing power in the 70's when the F-117 was
developed. Now, with modern computers being able to precisely
model how shapes will react to radar energy we can create curved
surfaces that are actually much more stealthy and have much
better aerodynamic properties.  RE: 20 year gap. RE: 20 year

it's the response of the "true stealth aircraft" comment - while
the F117 was, in fact, the first "true stealth aircraft" (though
some German WW2 flying wings turned out to be stealthy nearly by
accident), it's stealthiness could have been substantially
better, as evidenced by the B2 - a much larger aircraft with a
much smaller Radar Cross Section.  That's all.  RE: 20 year gap.
