AI ship design needs lots of help

Description

1. I have never ever seen the AI use different decks so far, so way more components than necessary are placed in "outer hull" while protected "inner hull" space is left unused

2. I have seen the AI designing "recon satellites" (small sat) with:
computer core, 4 times basic sensors, 1 combat sensor -- nothing else... (not even armor or shields) -- what the...???

3 I have seen the AI designing drones with no weapons or war heads at all (only computer & engines) but with ordonance storage and/or combat sensors on it... what for ?

4. I have seen the AI building many carriers without a single fighter in sight anywhere for a long time (quite a few rounds) that do nothing but run away in any battle as they have no fighters...
