Thanks for the detail Flanker Man but pegon had the closer answer. Just like our Tornado F3 and GR4, one is for fighting air to air and the other air to ground. I was wondering why two planes which look rather similar are make by two companies.
Thanks for the answers so far guys. 🙂 About the Mig and Su, I was wondering if one was a bomber and the other a fighter seeing that they look very similar.
