Okay, stopping short of pointing out other tools that are abused, in a much more detrimental impact, 4 minutes of information from the perspective of a projectile is much less of a concern unless they can transmit a dar dot (which doesn't seem reasonable that it would).
Simple cockpit view only (in this case it would be the nose of the torpedo).
If HTC, decides to add this, don't half step, add the hull hit and explosion sprites for a few seconds before you slap the camera view back in the tower. Even if torpedo just expires (4 mins runs out) run a fly by view of the torpedo first.
