The -V variant gained the Viper callsign. I don’t think it’s correct to call anything before F-16V “viper.”
Unlike many other military aircraft, Wikipedia does not have a complete accounting of every F16 in service–merely saying “4,500+”. So it’s a fair guess that there are still some non-Viper Falcons knocking about somewhere.
NCD these days is a mixed hodgepodge of NATO propaganda, US defense industry propaganda, laughing at wacky military shenanigans around the world, and pornographic degeneracy involving military aircraft and other vehicles.
NCD started as a spin off from Credible Defense, which is a community where all articles have to be well sourced, arguments well reasoned, and citations are required. NCD has exactly none of those things.
