Prefix code

The Prefix code is a numbered code individually assigned to each Federation starship.

It is a defensive measure, designed to help Star Fleet personnel combat enemies who have seized control of a ship of their fleet, and to prevent enemy ships from attempting to seize control of a Star Fleet vessel.

When the relevant code is entered into the computer system of another ship, that ship is able to remotely control systems on the other ship.

• This includes weapons and defense systems, which enables the controlling ship to reduce the seized ship's fighting capabilities in order to permit effective attacks.

However, it is possible for a knowledgeable enemy to take the precaution of changing the code.
