The following questions about Fleet Command pop up in naval game discussion forums from time to time so I might as well put the solutions in this thread..
Q- CAN WE DO BOL LAUNCHES IN FC?
A- Yes, for anti-ship missiles AND for torpedoes!
I discovered the way to do it only recently, namely when you see a purple ESM line from an invisible enemy ships radar, select 'Engage with Harpoon' (or whatever other anti-ship missile you're carrying) and move your cursor along the line til the crosshair icon appears, then right-click to fire.
Exactly the same applies when your passive sonar picks up an enemy subs purple engine noise line, but this time select "Engage with torpedo" and run your cursor along the line til the crosshairs appear, then right-click to launch the torpedo.
Q- WHY WON'T SOME OF MY HOTKEYS WORK?
A- Go into your computers Control Panel and set the keyboard language to 'US English'.
Also, make sure your Numlock and Caps Lock are OFF, or they might affect some hotkeys.
