Four Skjold class patrol boats

Skjold class coastal corvettes (skjold means "shield" in Norwegian) are a class of large, superfast, stealth missile craft in service with the Royal Norwegian Navy. The boats were formerly classed as MTBs (motor torpedo boats), but from 2009 the Royal Norwegian Navy has described them as coastal corvettes (kystkorvett) because their seaworthiness is seen as comparable to corvettes.

They were built at the Umoe Mandal yard. Although the Skjold class patrol boats remain the fastest armed craft in the world (60 knots /110 km/h) they still fall short of the unarmed Canadian Navy high speed patrol craft hydrofoil prototype HMCS Bras d'Or, which attained speeds of well over 63 knots/116 km/h.
