Okay, the Deimos was designed with four extra turrets on the side of the hull, same dual-barrel type that is used on top and bottom, however the game engine doesn't like those types. (Look at the BOX the game came in.)
As for the Hecate, start a new game. Watch the first animation in
Admiral Petrarch's speech. If you look there are 3 turrets shown on the top of the Hecate's "wing". In the game and the models I've seen, there are none there. (3 on top, 3 on bottom, 6 total on one wing, 12 total for both wings.)
It's one of those things that apparently didn't get edited out for lack of time.
Not to mention, The colossus cutscene's mentions one number for total turrets, the ship itself in Fred has much fewer.
And as for a wing of freighters taking out a sath? How the hell did you jump to that end? Flak and AAA’s aren't going to kill a sath. Even a terslash/light terslash/sgreen wouldn't work, the freighter would get decimated by the sath's beams. It has a lot of turrets, beams, lasers, flak, and missiles. I'd give the freighters about 10 minutes max before they were dead.
But we're forgetting, don't sath's have fighterbays? The larger freighters might have a couple fighters each, but come on. Stop being cynical.
Thanks Bob for the link, I'll take a look at it inna few.
Edit: Bad typing...
