BOL possible in Fleet Command?
 

Is it possible to do BOL (Bearing Only Launches) with anti-ship missiles in Fleet Command so that we can launch them at suspected enemy locations even if they aren't showing on the map?

Yes it's called a snapshot

I SOLVED THE FLEET COMMAND BOL THING..:)
Hey newcomers, when you see a purple ESM line it means there's an enemy ship with its radar switched on somewhere along it, so select your ship and hit "Engage with Harpoon" and MOVE YOUR CURSOR ALONG THE LINE until it changes to a crosshairs icon, then right-click to fire the Harpoon.
(If your ships not carrying Harpoons, select whatever anti-ship missile it is carrying)
Exactly the same applies when your passive sonar picks up an enemy subs purple engine noise line, but select "Engage with torpedo" instead and run your cursor along the line til the crosshairs appear, then right-click to launch the torpedo.
PS- another couple of tips-
1- If some hotkeys are not working you need to go into your computers Control Panel and set the keyboard language to 'US English'.
2- Also, make sure your Numlock and Caps Lock are OFF, or they might affect hotkeys.
