F-15 Has the best Weapon capabilities 8 to 6*AIM-120s and speed, enough fuel whit three fuel tanks loaded.
MiG-29S not as good Weapon capabilities as the F-15 but have same possibilities, u can load 4 (actives) called R-77 and (Heat seeking) 2ET,2R-73. And because off the size MiG is short on fuel, u really need to watch it.
I would say MiG, and F-15 in Lomac have same way off fighting because off the active missiles.
Su-27S/33 are a lite bit more pain in the arse when it comes to Weapon capabilities.
U don't have missiles that are active so U need to guide them all the way to the target.
R-27ER,R-27R,R-27EM but they have bigger range then the active missiles.
I would say the biggest challenge is to fly Su-33, U cant outrun anyone so u have to really think before getting in to the fight.
Neither any actives that can cover ur escape.
So me as a Su-27S pilot Dreaming about The upgraded Su-27SM where its possible to carry 8*R-77 or 4*ET and 4*R-77.
That would make the F-15 pilots cry. But that is only a Lomac dream. :)
