You need boats to be able to power project. You need tanks for combined arms warfare on the ground or else anything heavier than a taxi cab will unironically blitz you. You know what can be put on those boats? Missiles, which are logistically superior to traditional bombers in nearly every means and way. Bombers that the US is only really able to use against non-peer threats. This is why we're ordering the new Raider by the way, since stealth coating a missile is basically impossible, it's the next technological development necessary to combat China's technologically growing air defense network.
Also it doesn't help that we've been artificially stimmed by slapping "all rounder" on fighter aircraft and using those as bombtrucks. The US has over 200 F-15E Strike Eagles, the ground-attack variant of the F-15 and, effectively, used as a bomber. Fucking the C-130 has been used as a bomber! EVERYTHING IS A BOMBER IN AMERICA INSHALLAH
In conclusion, shut the fuck up, Murica fuck yeah.
