Re: Intrepid class VS a galaxy class, which was more powerful and adva That's not what the episode shows. Defiant blew up little bugs because it closed to within 500 meters before opening fire. Galaxy class couldn't do that due to being much less manuevarable and had to engage at distance. Even then, it took a kamikaze attack agains damaged Odyssey to bring her down. Defiant was better suited to engaging small ships at close range, which is what she does throughout the series. You don't see her attack the Vor'cha in Way of the Warrior do you? And as I said, it's not an arbitrary statement. It's how the real world as well as Star Trek works. In Star Trek, bigger ships have always had all sorts of advantages over smaller ships. What other instances other than the Defiant are you reffering to? Defiant was the only exception, and even then, they made the effort to show how it was negatively affected by so much power, including its speed being limited to Warp 9.5. Its main phasers are so powerful because they are of the pulse variety and because they drain power directly from the EPS, which is something that is not done with regular ships. Never are such statements made in connection with Voyager. Voyager is decribed as "Not as big as the Galaxy class, but she is quick and smart." That's markedly different from "Not as big as Galaxy, but vastly more powerful". Defiant was built as a warship from ground up (main asset being it's manuevarability and abletive armor against Borg), while Voyager is a small exploration vessel given to a science captain. A bigger ship like the Galaxy would have: 1. Bigger and/or more shield generators. 2. Bigger warp core (12 decks as opposed to 6 IRCC?) 3. Longer phaser arrays with more space inside to house the supporting equipment 4. Better torpedo launchers. Those launchers on the Galaxy seem to be 30-50 meters long. 5. More computer cores 6. All sorts of reduntant systems like extra transporters, shuttles (including 2 runabouts), cargo space, fuel space, larger torpedo complement, spare parts, etc etc.. It's very, very unlikely that in 7 years all those systems would have changed so much that they could be minituarized by a factor of 10. If by some crazy remote chance they did, Starfleet would have never built Galaxy, Sovereign or any of the other big ships in the first place, knowing that such technology is just around the corner. That being said, we see new Galaxies being built on a couple of occasions on Utopia Planitia (one of them at the same time as Voyager), so all new technologies will be part of the new ships. As for the speed issue, Enterprise had a maximum speed of 9.3 and was the fastest ship in the fleet if I'm not mistaken, but later in the show, that moves up to 9.6 without any external changes to the ship. When Voyager comes around, there is a new maximum speed, and then Prometheus takes over the mantle. The general trend in Starfleet seems to be that the speeds go up all the time, there is no reason to believe that all ships are not there and therebouts. Nebula seems to catch up to Prometheus just fine in "Message in the Bottle." Prometheus and Intrepid might still be the fastest in terms of sustainable cruise, or they might not, we don't know how it all works when it comes to speed because, as someone pointed out, warp coils, warp field geometry, etc all play a part.
