48,000 Tons: The Submarine Built to Survive Nuclear War

The Soviet Union built six submarines to end the world. Each one carried twenty ballistic missiles and two hundred nuclear warheads.

RIGSILENT explores the engineering, history, and psychology of submarines — told with the precision they deserve.
