I've updated SWAFT to include support for the fleet building competition.
At the moment this is limited to the MC80 Liberty expansion, but when details are released I will be adding support for the Imperial ship and also creating a text string output that's relatively easy to paste into competition entry form.
All of the details should be there for the Interdictor as well, is there anything you're specifically missing that I can hunt down for you?
I should correct my post. I'll be adding the Interdictor in the next couple of days - the details are already posted.
No Worries! I was just wondering if I could help, is all! 
OK - the Interdictor is up. Enjoy.
