Visby-class

A Swedish stealth corvette built almost entirely from radar-absorbent sandwich composite, designed for anti-submarine, mine countermeasure and surface-strike roles in the Baltic archipelago. Its low radar, acoustic, magnetic and infrared signatures made it one of the first true stealth surface combatants in the world.

Physical specifications
Length Overall length including gun/probe where applicable.	72.7 m

Naval

Displacement, speed, endurance and diving depth.

Naval specifications
Displacement Standard displacement in tonnes, the ship’s size class. Larger hulls carry more but cost more and are less agile.	640 t
Full-load displacement Displacement fully loaded with fuel, stores and munitions.	640 t
