Yes - make sure you hit the ammo stores. If you are within (IIRC) 1000m & at approx 90deg to the target the recog manual will give you little boxes around the different areas of the ship. Engines, fore/aft ammo bunker & fuel storage etc. All you have to do is click on the box of your choice and the torpedo is 'auto' targeted & updated so you will have nearly a 100% chance of a critical hit.
