ah... Just like RiffleMan & Metalnick, I vote Galaxy too....
... this is my most... most...x1000 favourite ships for all of the science fiction's ship I ever seen.
Since I though when u go to distance space (soo.... distance) I prefer to prepare for the worst.
Including to solve a difficult space anomaly (en route) that may can eat ur ship :angel (in this case u need a good/large science capability) or to face a strong "first contact" powerfull enemy ... like ... borg (u need a strong ship to withstand under heavy fire
, while u can't outrun them
, or give enough time while thinking how defeat the enemy).
Even though for the worst case that we can't win no matter what, we still can seperate the saucer and battle sect. The battle sect can be use to distract & ram the enemy vessel in hope to destroy or at least disable it, while the saucer can run away. The saucer also can be used as Colony ship in an habitable planet if necessary.
The bigger the ship, the bigger it's potential to carry the most advanced technology even in larger/ grander scale.
Bigger is better... oppsss... the enemy may say the same, bcoz it'll be hard to miss the shoot...
cough..cough.... (just kidding)
Well still I prefer a hybrid ship that capable for both a strong ship in battle (as Akira or Sovereign) as well as in science (as Nebula), so I shoose ...I mean choose...
Galaxy foreveeeer.......
....
hmmm... I even want to bring this ship into another dimension like St*r W*rs or B@Bylon V....
Ah... btw... if possible.. . we can modify the galaxy's hangar to board a or several defiant ship as a fighter... hehehe.... kidding...
