It is about the three ship classes. Constitution, Miranda, and Constelation Class. What are the different? Why making three different Ship Class if they are basically the same? ( I have read Memory Alpha and Beta and surprise that actually Miranda Class is not inferior to Constitution Class. Previously, I thought that Miranda Class was a monkey model for Constitution Class, or at least the cheaper version of it. But when I see the spec, I was surprise that Miranda actually has the same number of weaponry to Constitution, if not better / stronger. At least they have pulse phaser) For Constelation Class, why would they put 4 warp nescele (or whatever it is) when the performance not even better than the 2 warp Nes... errr Engine starship like Constitution.
