Trade Fleets are fleets used for trading. They have to be established by paying Mass Transit Cargo Freighters.

Trade Fleets start with a capacity of 100 .

Fleets do not require maintenance, but you may only have a limited number of fleets. By default, each player can support two trade fleets. Additionally, you can support one trade fleet for every Open Market Zone in your system. This means a starting player (who has one such zone) can support three fleets.

A new Trade Fleet costs 100 Mass Transit Cargo Freighters and has a base capacity of 100. To start a new trade fleet, you need to have an Open Market Zone to support it.

A Trade fleet may be upgraded any number of times. Each upgrade adds an additional 100 and costs 100 Mass Transit Cargo Freighters.

Trade fleet upgrades are subject to the completion limit: A Trade Fleet may only be upgraded by one step of 100 additional capacity per turn. Creating a new tradefleet is also a completion. Any number of fleets may be upgraded/created simultaneously however, so long as no fleet is created and upgraded in the same turn, or upgraded more than once in the same turn.
