The thing is, we see the dedicated transport Sydney
, and she carries no identifiable armament. All the other three designs to use those engines are more or less identically armed; if anything, the Constitution
is the least militant of them, with just two torpedo tubes against the apparent four of the competitors, and with just one more explicit phaser turret than the Constellation
(and perhaps actually four less
, if we assume the dorsal five single turrets of the Stargazer
are ventrally mirrored despite the model not actually having that detail).
"Geared towards colonization" sounds a tad thin if it entails adding some shuttlebays but also quite a bit of firepower. Perhaps "geared towards planetary assault" might be more like it?
