Cost, scale, and operational compromises keep fictional ships from becoming flawless television starships. Andromeda's Glorious Heritage class illustrates how supposed perfection can conceal crippling cost and insufficient numbers, while the Daedalus-class missile fit raises the opposite problem of too little magazine depth for a large warship. Missile performance depends on powered flight, terminal maneuver, detection, and the ability to restart propulsion, while an 'energy screen' may plausibly describe a whole defensive suite rather than one magical shield. Civilian solar sails show how slow but continuous acceleration can be efficient for in-system transport. Nuclear rockets expose the gap between mathematical possibility and deployment because materials, launch capacity, and radiation risk can make testing from Earth impractical. Theory sets the possibilities, while engineering and environmental constraints determine what can be used.

Practical fictional ships need limitations, defenses, and coherent physics
Imperfect ships become believable when their cost, defensive layers, propulsion, weapons endurance, and engineering constraints follow consistent rules.
