Well, realize that one of the things that the judges for the Titan Contest were so adamant about was that the Titan was NOT a warship in any way. It's a "peace ship." So, all the launchers you see on Sean's ship's mission-module are probe-launchers and have no weapons-firing functionality at all.
I, personally, think that was a DUMB DUMB DUMB position to stake out (not Sean's fault, mind you!) but this was their stated position - the Titan is "Starfleet getting back into peaceful exploration and moving away from militarism."
On the other hand, the whole point of this ship was to "go where no man has gone before" and that's an inherently dangerous proposition. When I did my version, I set it up so that it had the ability to dump a massive burst of firepower and then to run like hell... it would not be a warship, per-se, but it could hit an enemy with enough damage to disable them and allow the ship to get away. This was one of the things that my design got criticized for, in fact... "too militaristic."
So, Sean's ship is a "peace ship" but it would probably be possible to swap out the mission module and strap on a warship-module in its place... again, if a kit ever becomes available, I think it's obvious that would be the first major "upgrade" you'd see most people put on it.
