The Tjeld class were a class of fast patrol boats (FPB) designed in Norway. They were used as torpedo boats in Norway where this type of vessel were called MTBs or motor torpedo boats (motortorpedobåt). The class was also known as the Nasty class.

The prototype Nasty was designed, built and tested during the fall of 1957. The Tjeld class was developed and introduced by Boat Services Ltd. A/S, Oslo, in close cooperation with Royal Norwegian Navy officers with World War II experience in Fast Patrol Boats; the chief designer being naval architect Jan Herman Linge. The Norwegian Tjeld class vessels were constructed at A/S Westermoen Båtbyggeri og Mek Verksted in Mandal.

The design was also sold to the USA, Greece and West Germany.

Six vessels were built in the USA by John Trumpy and Sons [1] of Annapolis, Maryland (some parts, such as the keel and stem being imported). The US Navy used them as PTF boats in the Vietnam War.

Vessels

Royal Norwegian Navy

Twenty-two vessels were built in Norway from 1959 to 1966. This list is of the ships in the order of launch with the year of launch, the year the ship left the Norwegian Navy's hands and any other information about the fate of the ship.

All the vessels are named after birds or fish (and three sea mammals). Some of the boats were renamed as the bird names were going to be used for the Hauk-class patrol boat. The boats took over the names of other Tjeld class vessels which were sold in 1981.
