Ok, it seems (it seems!) I got a nice 3-deck, light-armored outer deck, non-melting down, capable of keeping all of its systems powered, with a small hangar and clamp, with a good radar and with quite the punch of missiles to launch from a very long range...Frigate. I am now left with over 10960 credits. After taking the price of the extra missiles I'm carrying, I am left with something around 8540 credits (yeah, those missiles are expensive).
Now I got some options ahead of me. I got 100 size of a whole Deck 1 vacant.
1- I could:
a) More missile ammo. (10 missiles :V)
b) More generator.
c) More heatsinks.
d) More radar. (probably the less useful, my current active radar is size 50 and range 1000; it would also require more generator)
e) Combination of the aforementioned.
Even those would leave me with some money. So about the remaining monies:
2- I could:
a) Substitute that crappy light armor for heavy armor.
b) Support vessel, specced for Longbow laser attacks (I may run out of missiles some day, although I dread said day).
c) Support vessel, specced for carrying the missiles and random junk.
d) Support vessel, fighter carrier.
e) Combination of the aforementioned.
Edit: Oh yeah there is also this:
3- I could build my huge ship once more.
As a further explanation of 2-b, I could simply turn all my missiles into shield-killers (most already are) and then get a smaller ship with a huge laser/ ballistic weapon capable of destroying armor like it was...something easy to be destroyed.
Of course I may be wrong and I may have to fix some kind of unseen fatal flaw, but with so many credits, I almost sure I can at least get the heavy outer armor and two fighter jets.
I am soon either posting or editing the spoiler with the frigate.
