Pyramid 3_34 Crush depth seems overly harsh

Don't all PDFs get updated? I thought that was the second biggest benefit after from Ctrl+F.

Pyramid errata is available here (the link can be found on the main GURPS errata index). The page is dated July 2010, but the most recent errata is for Pyramid #3/28 which was published in February 2011.

I'm pretty sure that's for Pyramid #1, not #3. At least, I see no reference to The Cursed Sword of Hsima anywhere in issue #3/28, let alone on page 13.

Real submarines have a streamlined outer form hull that is mostly flooded, and smaller spherical or cylindrical unstreamlined pressure hulls. This can be done in Spaceships as well, using a similar methodology as command armor (Spaceships #3/40). Also see GURPS Transhuman Space: Under Pressure for additional explanation.

Most of the submarines designed like you're mentioning are the ultra-deep diving scientific vessels, but the majority of submarines* have a single pressure hull for most of the length of the boat and flood chambers in the bow and stern.

There's a few oddball designs like the Typhoon-Class which have a spaced pressure hull, but those were special cases and designed to defeat a deficit in anti-submarine technology.

* A vast majority of submarines have been warships.

-- Not clear how I was confusing. The single pressure hull can be much smaller than the outer form hull (the Seawolf pressure hull looks to be about c. 50% the volume of the form hull) which Spaceships doesn't account for (and frankly, neither did base Vehicles which is why I tweaked that stuff quite a bit for Under Pressure). Not ENTIRELY sure smaller pressure hulls works out in Spaceships though, because of the way that armor dDR scales . . . probably need to look at that more closely.

That sounds like having a smaller ship inside one made almost entirely of armor.
That makes a lot of sense especially for low TL vessels like modern ones.

That's basically the idea in a nutshell, yea.

Deep ocean exploration impresses the somethingorother out of me. We're going to have to send probes to Venus or one of the gas giants before landing on another planet gives me quite the same level of "You did WHAT?" Which might be mild claustrophobia talking, but still!

Second volume, according to the blurb at the bottom of the sample web page, but the publication date makes it seem like it should be from the first volume.

The reprinted article appeared in the second volume of Pyramid. If you look up top you see it was reprinted from Pyramid #28, which is from the first volume.

I'm always amazed that we know more about the MOON, than we do about the surface of the ocean. There could be an entire civilization of cephalapods down there, that we don't know anything about...
