The Pentagon conducted a series of secret chemical and biological weapons tests involving military personnel in the 1960s and 1970s. Veterans groups and members of Congress are demanding to know exactly what happened – and who has suffered.

The tests, known as Project 112 and SHAD (Shipboard Hazard and Defense) involved some 6,000 military personnel between 1962 and 1974, the Vietnam War era. Most served in the Navy and Army. The purpose was to identify any weaknesses to U.S. ships and troops and develop a response plan for a chemical attack.

The tests involved nerve agents like Sarin and Vx, and bacteria such as E. Coli. Sarin and Vx are both lethal. According to DOD documents, death can occur within 10 to 15 minutes of exposure to a fatal dose of Vx.

“Veterans were exposed to some of the most extreme and hazardous agents... and they now suffer from debilitating health care conditions,” said Ken Wiseman, senior vice commander of the Virginia branch of The Veterans of Foreign Wars, one of the nation’s largest veterans groups, at a press conference outside the Capitol Wednesday. They want to know more about the extent to which service personnel were exposed.

The Pentagon did not immediately respond to request for comment.
