“'The project benefits from all the uncertainty and speculation. Poseidon is primarily a psychological weapon,' . . .  'Submarines carrying them are likely tasked with launching the torpedo drones against high-value targets after a large-scale conventional or nuclear war has already been settled, wreaking havoc against an opponent’s coastal cities regardless of who wins,'” - Ina Holst-Pedersen Kvam.
