Aviso
From Wikipedia, the free encyclopedia
An aviso is a kind of French dispatch boat.
In the Dictionnaire de la Marine Française 1788 – 1792 (by Nicolas-Charles Romme), they are described as "small boats designed to carry orders or advices".
Modern aviso have grown to be combat-capable ships, smaller in size than a corvette, but greater than patrol ships. They typically have roles in anti-submarine coastal defence.
