@Hielor, it was still in the same mindset that there would be 'no-dogfights' if you could have stand off weapons, as history shows, you cannot bank on that.
Standoff weapons have come a long way in 50 years.
In modern engagements, dogfights are sufficiently rare that it makes exactly zero sense to invest time and money to R&D equipment that will only be useful during a dogfight.
