Twilight of the Arnor allows you to let the game auto design ships for you using templates. To enable this you must first tick the option in the Option screen in the Interface tab.

To set what type of weapons and defenses you want your ships to be designed with open the ship editor and click on the focus button. A new screen pops up with six sliders, three for weapons and tree for defences.

With these sliders you tell the game what kind of weapons you want on your ships and the type of defenses. Here's a few examples:

  • Setting 50/50 mass drivers/missiles will result in mass drivers and missiles being combined.
  • Setting 100 mass drivers will result in only mass drivers on the ship

The same applies to defenses.

Auto designed is triggered on a turn when the following technologies receive an upgrade:

  • Weapons
  • Defenses
  • Miniaturization
  • Hulls

Some techs are used but do not trigger new designs

  • Range
  • Sensors

Defenses only seem to be used on medium hulls or higher and engines seem to be ignored as well.

If you trigger an auto design update and you're building an old ship the shipyard will automatically update its building que similarly to a manual Update.
