It looks like this document from Cold Navy will solve the problem. The Cold Navy ships have been designed with varying tech levels depending on their navy and year of production. If I fill in the correct tech levels in the spreadsheet it ought to solve the problem.

Thanks to everyone for your help.

Nice one! Thank you. I will look at this with great interest.

I tried pasting in Tech Level 1 for the engine, shields, etc. It makes a big difference but it doesn't make all the ships legal. There may be tech level adjustments to some of the Special Equipment. I will try some more ships tomorrow and see what I find.

Hello all, I am new to the forum having recently bought the rules after being inspired by the Cold Navy ships.

Cold Navy's models each come with a Starmada record card. For practice with the Ship Construction Spreadsheet I typed in a few of the ships, just to get the feel of how things work.

I've tried three ships and each of them has given me a big negative number of SU left after finishing construction.

Has anyone else found this? Is it a mistake in the Cold Navy construction or, more probably, a mistake I've made keying in the numbers?

Thanks in advance...
