I’ve been reading a bunch of articles and watching videos about “game-changing” naval tech (railguns, stealth destroyers, hypersonics, drones, etc.) and it feels like half of it is marketing or budget politics.
From a practical standpoint—maintenance, training, real-world threat environments—what do you think is the most overrated naval technology right now (or in recent decades)? Not “useless,” just way more hype than payoff. I’m especially curious where the line is between good capability and expensive distraction.
