Skjold-class corvettes (skjold means "shield" in Norwegian) are a class of six 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 corvettes (korvett) because their seaworthiness is seen as comparable to corvettes, and because they do not carry torpedoes. They were built at the Umoe Mandal yard. Although the Skjold-class corvettes remain the fastest armed craft in the world with 60 knots
