Triton-1: Spetsnaz’s unknown Swimmer Delivery Vehicle (SDV)

It was a powerful demonstration to the Soviet Navy and ensured the future of the frogmen and their craft..... Read More >....

Stealth: Raft Mountings in submarines
In submarine warfare stealth means quietness. During much of the Cold War US and British submarines had a material advantage over their Russian counterparts because of the attention paid to quieting.
