Captain, this is your XO reporting to you the battle results:
We have discovered that we can hear ships screws when on the surface and when we are travelling at high speeds. We also found that we can detect ships screws when the enemy ship has no screws turning.
We have discovered the same thing as your Operations Officer, Lieutenant Michael Wood.
We should request a temporary "refit" to come in the coming days that can fix our "bad" hydrophone
