This torpedo
against blue crystal armor with collision damage on On a side note, the torp was reduced to it's ship core which was overheating and thrown out the bottom of the target at a couple hundred m/s while the target was sent spinning off for about 17km.(Edit: actually the glass block test sent the target spinning

Glass blocks with two holes are from identical torpedoes. The lower crater impact in the face is with collision damage off from 300m. The upper impact that stretches into the glass is with collision damage on at @ 750m/s from roughly 1000m. The ship core exited the back of the target(100m) and was destroyed.
I may have underestimated them somewhat, but for all the expense and trouble to make one, plus space required to use them and their limited capacity, the bang is probably not worth the buck. Keep in mine that mine were capped with advanced armor, but with a warhead exposed for this test. It would be extremely vulnerable to PD.
I posted a bomber with two in the content section that use a full armor cap for penetration of the target that I haven't tried out on the range. These would be less vulnerable because no warhead is exposed, but the rest of the casing is far more fragile than the non-capped torpedo, and they move slower(@450m/s). I used these as they were not just solid blocks of warheads, which are extremely vulnerable to everything including sneezing, and seemed to be of reasonable size to be considered a viable small torpedo(5-8 warhead block cores). Making bigger torpedoes would make them more liable to be picked up and destroyed by turrets set to any or under the direction of the pilot.
Overall, I'd still like to see an increase in warhead power maybe 2-3x what it is now. PD should definitely be allowed to hit these things and, if the torp is in a casing, might not be enough to stop them. On the other hand, a protected torpedo is useless with collision damage for the server turned off, which it is by default. The only way then is to leave the warhead exposed to make it extremely vulnerable again. This also makes it a much less potent weapon and easier to kill, where I think that perhaps PD would be OP against them.
