In Norway this type of vessel is called a missile torpedo boat (MTB).
The class was named after its lead vessel, Snøgg, which is a Norwegian word meaning "fast".
Six vessels were built during 1970 and 1971 to replace the ageing Rapp class.
Designed by Lieutenant-commander (later Captain) Harald Henriksen as a development of the Storm class.
None of the vessels are left in Norwegian service today, they have been succeeded by the Hauk and Skjold classes.
