I've stripped the remaining 450 lines of code as it's got the dread 
double spaced google disease, please see my signature.  You're also far 
more likely to get responses if your question follows the guidelines 
given here http://www.sscce.org/, particularly if someone already has 
pygame installed, which I don't.

However I did note one area where you can simplfy your code.  You've 
many lines using this type of construct.

for i in range(len(ships)):
     doSomething(ships[i])

There's rarely a need for this in Python.  Use this instead.

for ship in ships:
     doSomething(ship)
