..a multi-role airplane cannot do the job as well as a single role airplane
1. you can't build a plane to be optimized for a certain role if you have to attach multi-role systems
2. undeniably a pilot cannot be trained as well for a certain role if he has to train for many roles
TRue but the cost of having so many different kinds of air frames is just cost prohibitive for the US, China, Russia and any Military of any size. Right now, the F-35A and B are the best all season Fighter made. You keep pushing the A-10 but in a fight with eitehr the Rissian or Chinese, it's just target practice.
In truth, ANY modern combat aircraft against a peer opponent is just "target practice". And its even worse for drones.
Ever read what the NATO loss rates for their tactical aircraft were estimated to be in an all out conventional war against the Warsaw Pact in the 1980s?
50%. With similar or even worse losses for the Warsaw Pact forces.
That's 50% in ONE WEEK of combat. In short, there would've been state of the art combat aircraft falling from the skies like confetti.
----peer opponent ......we saw what the Israelis did to Syria, etc and the US to Iraq, etc......I'm not too sure the Warsaw Pact was any better than Syria or Iraq
In raw numbers alone, the Warsaw Pact was vastly superior to Syria and Iraq.
The Warsaw Pact had such a numeric advantage, they could have taken continental Europe. By the end of hostilities, both sides would be using junk since all front line equipment would have been lost. No, the Warsaw pact still could not have taken the British Isles. And it would give time for the US to get the buildup of good stuff. But for a time, it would be the A-10 and A-7 against the Su-7 where the SU-7 vastly outnumbers the quantity of both the A-10 and A-7. The Mig-23 and 25s would be gone, the F-14 and F-15 would be lost until the resupply. By that time, there would be enough Mig-21s and new Mig-25s in enough quantity to offset the superior F-15. And there wouldn't be enough F-16s to really count yet. Oh, and the F-4 would still be a player but much fewer in numbers. And that is just Air Power.
On the ground, the superior numbers of the T-72 would far outweigh the M-60 which is a better tank. Yes, the T-72 ended up becoming a better tank for Russia and the US replaced the M-60 with the M-1 but there are still some countries using the upgraded M-60 Tank that is still superior to the upgraded T-72. In the end, there would have been a lot of wasteland to contend with, destroyed cities, lost crops, destroyed roads and bridges, etc..
The Winner? If you go by territory claimed, Warsaw Pact. If you go by just how back Europe goes to the Stone Age, there are no winners.
