So for the first versus lets look at two ships. The USS Enterprise E flagship of the Federation, a body containing hundreds of planets vs the GSN Harrington. The GSN Harrington, named after the main character of the series, is the proud flagship of the Grayson Space navy. Grayson territory comprises one system and one major planet with astroid belt.
Seems like no contest right? The Enterprise should be able to turn the Harringtoninto scrap right? After all the Federation is a couple hundred times larger than Grayson, there's no way that tiny little Grayson could produce a ship able to take on the Federations best right.
You might be surprised.
The stats of the Enterprise E are well known so I won't bore you with them. Consider the weapons on the Harrington.
Noted as an SD(P) class ship meaning that it's a SuperDreadnaught of the Pod laying variety. It's constructed to lay a series of "pods" containing 8 40ton missles. These missles have an engagement envelope of 30 MILLION Kilometers and an average acceleration of 46,000 G. There are three types of of missle heads ECM, nuclear, and LASER. Before the Star Trek kiddies start moaning about how the navigational deflector makes the enterprise immune to lasers know that theses lasers are produced by a nuclear explosion along with a gain material to pump out high energy gamma ray lasers. These lasers have an effective range of 25,000 kilometers.
These missles are the main armament but not the only. Numerous GLASERs are also mounted. GLASER stands for "gamma ray amplification by stimulated emission of radiation".
"Hah! A few torpedo blasts as we use the Picard trick to warp in front will do" I hear the Trekies say. Not so when the ship your against masses "6,000,000–8,500,000 tons".
Cheers.
Next time:Shields or how to stop all those missles.

BTW: Love the site, wish the technical revalations for Revenge of the Sith was up but oh well. I'm sure Darth Wong has a life that needs tending to.
