Lol people hold on to that wargame so tightly as some Pinnacle of triumph over western armed forces, but the reality of the situation was that the sub commander in question went rogue and did something they weren’t supposed to do in order to win. Also at the end of the day it’s a fucking wargame, it’s practice, and nobody really cares how well you do in practice because it’s all about how you perform in the big game.

Also as you noted the Americans did what we always do when situations like this happen, we game planned for never letting it happen again, this was an embarrassment for the US Navy, and you can bet it’s something they’re constantly working on never letting happen again, these are serious professionals who’s lives revolve around continuously planning ways to win against any situation while losing as few of their people as possible.
