But according to the account that follows—told by a man whose father worked on a secret project aboard that submarine—the official story conceals something far darker.

The Edgewood Arsenal Experiments and Mutation Breeding

At the core of this account is the Edgewood Arsenal human experiments, a Cold War-era program that tested low doses of chemical warfare agents on military personnel while exploring countermeasures like protective equipment and vaccines. One very secret portion of this program continued long after the official end of Edgewood's human experiments in 1975. The driving concern was how to fight a war in which nuclear weapons could decimate entire armies. Radiation exposure, even at minor dosages, would reduce a soldier's cognitive functions within two hours, leaving them effectively disabled before death.
