I love this game, but a couple tips. You gotta keep researching, click that enable air patrol box, set your ships on patrol paths. Simple things, but they add up
And you can turn the notifications off for auto pause. I'm sure in the options (which you never checked) and the little box you can see at 45:57 but noooooo. It's content to complaiiiinnnnn all video omg so good yum yum content so good.
Perhaps next time you should first target the radar, over horizon radar and missile systems. Then the enemy is defenseless and your missiles can do their work much better. You lost a lot of missiles because they were just passing those defense systems. ;)
