Clarification
Despite the fact that I wandered into taking about armoured vehicles in my opening premise it really is combat aircraft that I was referring to.
Waves of cheap aircraft in a proper shooting war nowadays are really only going to produce lots of dead pilots. Decent aircraft with decent weapons (ie don’t use an SU-35 with low level, dumb bomb deliveries) are definitely the order of the day. Or leave them at home.
