Comment on Tarasque Battlecruiser Ortho by ILJackson

you have to sacrifice a lot (sometimes painfully) for storytelling, esp. in space science fiction. In reality, you'd make a bunch of robot suicide drone missiles that would hit enemy ships at FTL speed as soon as they were detected. The battles would be all from beyond any physical range, and conducted from planetside underground bunkers. You'd either have to build more ships than the enemy had drones or vice versa to hope to win. Once you got in close you'd snag a few meteors and chuck them at the enemy planet while the enemy ran for it, unless you wanted to actually live on that planet. Then you'd just send down drones with short-lived biological weaponry to poison the water supply, blockade the planet, then after a month or two send down the cleanup crews to clean the water and the bodies.
