Did you read the posts after mine?
You dont need 50 aircraft,remember that Iran has no air assets or real air defence.
It only has ground forces which means when you rule the skies you have the upper hand,the ground forces can be taken out easy.
The US has satelites,every movement on the ground can be seen and imediately eliminated by missiles from ships or air assets.
how do you think US prevented Iran from attacking them? you need air support, and for constant air support you need that many aircraft,
fighter jets can't loiter for entire day, they need to be swapped and their stations replaced within few hours
also satellites don't provide reliable constant real time intel, thats why US has highly secretive RQ-180 and is developing SR-72
