Your logistics rating determines how many ships you can combine together in a fleet. The size of a ship's hull determines how many logistics points it takes up:
- Tiny - 2 points
- Small - 3
- Medium - 4
- Large - 6
- Huge - 8
In Dark Avatar, the logistics values are:
- Tiny - 2 points
- Small - 3
- Medium - 5
- Cargo - 5
- Large - 7
- Huge - 10
In Twilight of the Arnor, the logistics values are:
- Tiny - 4 points
- Small - 6
- Medium - 10
- Cargo - 10
- Large - 14
- Huge - 20
Your logistics rating can be increased by researching logistics related technologies:
| Level | Increase | Cumulative |
| (typical base) | +6 | 6 |
| Basic Logistics | +3 | 9 |
| Enhanced Logistics | +6 | 15 |
| Advanced Logistics | +9 | 24 |
| Expert Logistics | +12 | 36 |
| Ultimate Logistics | +15 | 51 |
In Dread Lords having superior logistics (and being able to create larger fleets) is a crucial edge in Fleet Combat. The larger fleet can concentrate their superior firepower on a fewer number of targets, yielding a decisive advantage.
With Dark Avatar's changed ship combat mechanics having lots of ships in a fleet usually means a player will just lose lots of ships in a battle. The bigger the firepower of ships, the more that's true.
Higher logistics ability also reduces the cost of building starbases by %1 per point (as per theStarbase page).
