Sweden’s New Submarine is Probably the World’s Stealthiest

Saab’s Ghost stealth technology, which stands for Genuine HOlistic STealth, is Saab’s quietest technology ever—and even quieter than their upgraded Gotland-class submarine. This incredibly low acoustic signature is achieved through a variety of means. The Blekinge-class makes use of rubberized mounts and baffles inside the submarine to reduce noise cause by on-board machinery or crew. Additionally, frames within the sub are filled with “acoustic damping plates” that absorb ambient sound from within the submarine.
