The F-19 was what people speculated the rumored "stealth fighter" would be named. There had been rumors for years, but the public didn't see it for the first time until 1988.
In Tom Clancy's book Red Storm Rising, about a hypothetical Third World War in Europe, he conceives of it as something like the F-35 ended up becoming -- a stealthy multirole aircraft (fighter-bomber). They called it the "F-19 Frisbee". The 19 comes from the fact that the previous fighter designation was for the F-18 Hornet.
