GURPS Spaceships for THS conversions?

I hadn't realized it needed updating until you mentioned it.

Hmm, I like this idea a lot. Just so I'm clear, you take a 1-point power system and it provides .5 power so can power .5 of a weapons battery, OR you use a 2-point power system and use 1/3 of it (to get 2/3 power point) and it powers 2/3 of a weapon battery?

Yes

The price doesn't seem to make sense the way you did it though ... a 15 weapon battery using a fuel cell should be cheaper than a 20 weapon battery using an MHD. I would simply multiply the cost for each system by the % of it you are using (I rounded any fractions up to represent the cost of integration):

Self powered Tertiary Battery (Fuel Cell) [Hull]
15 weapons per battery
Cost SM7+ $: 0.85M 3.5M 8.5M 35M etc
Uninstalled: 1 3 10 30 etc

Self powered Tertiary Battery (MHD) [Hull]
20 weapons per battery
Cost SM7+ $: 1.1M 4.5M 11M 45M etc
Uninstalled: 0.75 2.5 7.5 25 etc

Yup, those numbers look right. However, Spaceships module prices are typically only shown to one significant figure, and occasionally two when the second sig fig is a 5. And even then only every other SM has two sig figs. Also the battery prices were chosen so that the price for each weapon in the battery was a nice number of one or two sig figs.

So when calculating new numbers off original module prices that are severely rounded you don't need to be too precise; and you need to consider divisibility; and you need to try and maintain roughly a 1:3 ratio between SMs. However I agree that 20 weapons should be dearer than 15.

My original prices don't pass all those tests either, so I suggest
- fuel cell 750K 3M 7.5 30
- MHD 1 4 10 40
