HSwMS Visby (K31)

Swedish corvette HSwMS Visby (K31) at Kiel Week 2002.

The Visby-class Stealth Corvette is the latest class of corvette to be adopted by the Royal Swedish Navy after the Göteborg and the Stockholm-class corvettes. The ship's design heavily emphasizes low visibility or stealth technology. The first ship in the class is named after Visby, the main city on the island of Gotland. The class has received widespread international attention because of its capabilities as a stealth ship.

The ships are designed by Swedish Defence Materiel Administration (FMV) and built by Kockums AB. The first ship of the class was launched in 2000 and since then the construction was fraught with repeated delays. Finally in December 2009, the first two ships of the class were delivered to the Royal Swedish Navy by the FMV.
