Stock ships redesign - the practical approach

Sorry for the lack of update yesterday. I've been reading and testing. I realised that because of the heavy armor there is a point where the effectiveness of the long engine bells and the higher exaust velocity of more effective fuel mixtures like the LOX/Methane is really counterproductive. So after encountering this useful spreadsheet and reading this I've gone full Hydrogenperoxide/RP1 for both offering me decent enough exaust velocity and very high density. For the devastator I've also found that several smaller fixed engines are giving me better performance because they are so much shorter and do not escalate the armor weight that much. The reduced turning speed did not turned out to be a problem for the moment but I experimented with RCS thrusters to boost it, sadly they turned out to make the missiles much less resistant ot laser fire. However it seemed to me that the RCS was behaving much better than before the patch so great work qswitched !

I'll try to wrap up the new missiles after work and I'll try to post them later today.

I saw the spreadsheet in the Solar System Organization of Standardization thread... why is there something wrong in it ?
