Re: "but there's no convincing defence systems."
"Let me see first a working hypersonic missile in combat-representative conditions... also, I would also like to see something flying at very high speed in very dense air (skimming the surface).... first, it requires a lot of energy, second, a lot of that energy turns into heat.... also I would like to know what happens to the water in front of it due to the shock wave... you have unbounded optimism also...."
There's also the fact the faster a missile flies, the harder it is to turn (matter of sheer inertia, a known issue in dogfights), meaning a faster missile is much easier to lead and track. Technologies like the Phalanx only need a few seconds, and even at 1 mile a second, it's going to take a few seconds for it to reach target from the radar's horizon (even longer with an AWACS deployed to extend that horizon).
