The ''Alta'' class was built by [[Kværner]] [[Mandal, Norway|Mandal]] during 1996 and 1997, while the related ''Oksøy'' class was built in 1994 and 1995. A total of 9 vessels were built, 5 minesweepers and 4 minehunters. The [[catamaran]] hull is built in a [[Glass-reinforced plastic|fibre-reinforced plastic]] sandwich of very low magnetic signature.<ref>{{cite web |url=http://www.navyrecognition.com/index.php/news/defence-news/year-2013-news/september-2013-navy-world-naval-forces-maritime-industry-technology-news/1253-kongsberg-to-supply-minesniper-mk-iii-mine-disposal-weapon-system-to-royal-norwegian-navy-.html |title=Kongsberg to Supply MINESNIPER Mk III Mine Disposal Weapon System to Royal Norwegian Navy |date=September 20, 2013}}</ref>

Two large fans located on each side create an air cushion between the two hulls and a front and aft rubber skirt, lifting the vessel, giving small drag and a high cruise speed, as well as low susceptibility to the shock of exploding mines since only a small portion of the hull is actually exposed in the water. Propulsion by [[Pump-jet|water jet]], again one in each hull, gives a low acoustic signature. A degaussing system gives the vessels extremely low electromagnetic signature.{{cncitation needed|date=March 2015}}
