Even the D6 is inaccurate:Iain McGhee said:Different ship really. The TOS D7s are the same as the Mongoose D6 design, that one has all sorts of upgrades in the SFU which is why it has the larger and differently shaped hangar/engineering block.
GalagaGalaxian said:Well, the Original Series was several years before the General War (about 10-15 from the nebulous "mid-war" point at which the ships are selected from) and pretty much every ship in the game has received Modernization and War-Readiness refits just before and during the opening years of the war. IIRC The D6 had its rear shields beefed up a tiny bit and it's boom Ph-2s upgraded with better Gyros to Phaser-1s.
This is obviously why the D6 looks slightly different, yeah!
