Having a hard time figuring out where the utility of this ship is (this discussion assumes you get your Codex ships early enough to be useful, ie, before you develop your own other aircraft). I picked Red, so I have a choice between it, the Snake, and the Scorpion. Given the following, I didn't even buy one yet, because I don't see it being useful. The Scorpion is obviously the main transport, happens to be fast enough to keep up with the Runabout, and catch the slower Megapol/Bandit/civvy stuff (although vs Megapol and Bandits, it's probably better to use the Snake to avoid damage). The Snake is a good multi-role ship, serving as light transport/intercepter, being durable enough with its shield to deal with most interceptions without taking (much) damage, although being slower, it can't catch some things. I had exactly one Heavy weapon (the codex choice) until eventually unlocking the contact to buy the Ramjet, which has expensive ammo. So the Scarab's two heavy weapon slots don't seem that great early, I've put my one heavy weapon on either the Scorpion or one of my Snakes as it is. It's slow, so it can't catch anything but slow civvy traffic, although I could see maybe using it to escort the Scorpion vs something with radar. And the Snake does that better anyway (and can easily handle most of the small ship crews by itself anyway). The Snake is even better as a pilot trainer too, since it uses 3 instead of 2.
Does it become more useful after I start unlocking STC modules and other upgrades (I think some of those fit in Heavy slots, so that could come into play then)? The boosted power/damage from its special ability seems to imply it should be used as a heavy intercepter, but that seems a little insane until I get better weapons (and its lack of speed works against it there, too) and by then, I'll probably have better aircraft. I don't even see a way to maybe "improve" it to the point of where I think it would be worth having, although maybe increasing the armor from 6 (the lowest weapon power of enemy craft looks like 15, I'm guessing they do the same 50 to 150% possible damage roll? Or do they work differently?).
What am I missing here?
