The only reason they needed them was to put them for days on end ready to roll in and drop oldschool bombs on Moscow and shit. Sure, arguments could be made for reconnaissance but satellites (and now drones) defeat the purpose of that as well. Plus, we're not keen on spending shittons of money on military equipment anymore with our economy, which is partially why the Navassa Island is using (modernized) guns for shore bombardment. A cannon shell is cheaper than a multimillion dollar Tomahawk missile.
