This is easily done in the third Japanese mission, Battle of Java Sea. At the start the Electra is closing in from your port side; simply turn towards him and run at full speed until he is about 1.6 miles out. Then slow to quarter speed ahead and turn hard starboard to unmask your full arsenal and hit him at maximum range. Aim for the magazine and fire your shots individually for increased accuracy rather than holding down the trigger. You can get two full salvos fired within the 15 second timeframe and that will easily sink the destroyer even on Veteran. If the achievement doesn’t pop, restart the mission and try again (this usually would only happen if your DD escort starts firing before you do, which would indicate you need to fire at longer range). Since this is right at the beginning, it is easy to attempt multiple times if you have problems.
