The Visby class corvette is the first vessel in the world to have fully developed stealth technology, combined with high operational versatility. The outstanding stealth properties fundamentally change the ship's survivability and improve its mission effectiveness.

Linus Fagerberg has performed research and aquired his Ph.D. within the field of the compression strenght of sandwich panels similar to those used in the Visby class corvette.

The Gotland was the world's first submarine class in operation with an air independent propulsion (AIP) system. The Stirling AIP system, combined with a number of unique features including overall low signatures, extreme shock resistance and a powerful combat system, provides the ultimate in non-nuclear submarine technology.

Linus Fagerberg has been performing design evaluation and stress analysis on composite structures for submarines.
