Default High/Ultra-Tech Versions of Low-Tech Armor

Which should I go with?

The rules High-Tech has for them, or what Low-Tech II has?

I'm almost tempted to do both since that's the only way to have a Very Hard Steel (TL7) Cuirass be closer to a HT Corselet in weight and cost.

Without using both, the Cuirass is DR10, costs $2520 and weighs 25.2lbs. By halving the cost and weight, it's then $1260 and 12.6 pounds. The Steel Corselet is DR10, costs $600 and weighs 12 pounds. Both offer the same coverage (Torso).

But I don't think the HT rules on steel armor were made with LT II in mind.

They couldn't have been. HT came first.

Yet, that's the only way to get HT steel values closer to LT II ones. Really it seems like they went for different extremes in how much better modern steel is.

The weights of body armour in High Tech are off because the real items cover a lot less of the body than HT assumes. The hardened steel armour in Low-Tech would cover steel plate up to TL6 but, from TL7 onwards, some fancy modern alloys and advanced hardening techniques make steel even more protective. Today they can make steel more protective than titanium alloys of the same weight.

Cost will be lots. The raw materials cost less than in earlier times but labour is much more expensive. You are looking at around 20 thousand dollars to get a decent custom fitted plate harness made today. The one that Dr Tobias Capwell commissioned from Robert MacPherson in 2005 was estimated to be worth around 56 thousand dollars at auction a year or two later.

IIRC the author of the Steel Corselet in HT has said that it should be DR10 from the front and DR4 from behind (this will effect weight calculations)


Personally I'd recommend using the armour design articles in Pyramid 3-52 and 3-85 for creating High tech (and Ultra tech) versions of low tech armour

It should also only cover the chest, not the entire torso.

The 'Steel Corselet' in HT covers 'torso' which doesn't include the groin, location 11 in Basic. In LT, 'torso' is 9-11 and includes the abdomen.

So the equivalent in LT II for the Corselet is Chest: $1890, 18.9 lbs.

Grossly overestimating coverage is the standard for GURPS; aiming for chinks in armor should probably be closer to a -2 or -3 than a -8.

It only covers hit locations 9-10, the same that are said to be chest in LT. So it already does only cover chest by LT definitions...

Not according to the hit location diagram in Basic Set p. 282. The groin location only covers the groin, not location 11. The Torso location in HT covers areas 9-11.
