When a fictional warship has too many guns

Which science-fiction warships seem most overarmed?

Examples range from an unnamed ship with impossible magazine and turret arithmetic to missile-covered vessels and an armed mobile world.

One unnamed fictional ship is criticised for carrying so many large guns that its ammunition would consume the available hull volume. Its claimed battery of 100 guns also cannot fit entirely into triple mountings: that arrangement would require 99 or 102. Foxo offers a different example, a compact spacecraft carrying a large nuclear arsenal alongside a crew of seven in capsule-like quarters. Further suggestions include a missile battleship whose bridge sits on a launchable missile and an Ork-controlled mobile world with ammunition stores extending into its mantle. These examples use different standards of plausibility, from an ordinary magazine-space problem to deliberately extravagant fictional technology.
