The keel laying of the new corvette Visby at Karlskrona last 17 December marked a major milestone in the Royal Swedish Navy's YS 2000 program. More than ten years ago, the Defense Material Command (FMV) initiated a series of design studies to meet the needs of future surface warfare. Following trials with the technology demonstrator Smyge, the choice settled on a new multirole corvette, designated YS 2000.
It was a flexible design, with top performance at both low and high speeds and the ability to undertake mine countermeasures antisubmarine warfare, mine-laying, surveillance, and surface combat missions. The hull, which has a low radar cross-section and low acoustic and magnetic signatures, is built of a composite sandwich consisting of a polyvinyl chloride core with carbon fiber and vinyl laminate to give maximum strength and rigidity, low weight, good resistance to shock, and low radar and magnetic signatures.
