The down sides are obvious...it's vulnerable to ever evolving advanced missiles....the air environment is rapidly becoming unsurvivable for older aircraft...thus our unpopular but necessary retirement of the A-10, another beautifully ugly killer.
They keep saying they are going to retire the A-10 but yet they have deployed it to the Strait of Hormuz. While old it’s still fills a role that no other aircraft can quite manage to fill. Plus the best part is after the enemy sees it in action they fear it. If you have ever seen one in real life action you will understand why. When the A-10 rolls out on a target and lets loose it’s a sight no one forgets nor do they forget the sound of it.
