Ok so i'm pretty new to this so i might be missing something.

I bought an ISS three times, and each time i loaded it up, 'till the total cost was about 1 mill. credits (5,000 fighters, 2,000max shields, LR/P scanners, mines, etc.). And each time i thought it necessary to cristen the new ship with some alien blood right? So i go to my neighborhood aliens, and i attack them. Well wouldn't you know all three of the first ones i fought had corbomite devices up the wazoo. So here i am, set back about 3 mill. creds, and i don't know what to do. There seems to be no way around these corbomite devices. So i ask of all of you, what do i do? Thankx for the info.
