Aviso
From Wikipedia, the free encyclopedia
An aviso (formerly also an adviso), a kind of dispatch boat or advice boat, survives particularly in the French navy.
The Dictionnaire de la Marine Française 1788 – 1792 (by Nicolas-Charles Romme) describes avisos as "small boats designed to carry orders or advices".
Modern avisos have grown to become combat-capable ships, smaller in size than a corvette, but larger than patrol ships. They typically have roles in anti-submarine coastal defence.
