Project SHAD, an acronym for Shipboard Hazard and Defense, was part of a larger effort called Project 112, which was conducted during the 1960s. Project SHAD encompassed tests designed to identify U.S. warships' vulnerabilities to attacks with chemical agents or biological warfare agents and to develop procedures to respond to such attacks while maintaining a war-fighting capability.
Project SHAD was part of a larger effort by the Department of Defense called Project 112. Project 112 was a chemical and biological weapons research, development, and testing project conducted by the United States Department of Defense and CIA handled by the Deseret Test Center and United States Army Chemical Materials Agency from 1962 to 1973. The project started under John F. Kennedy's administration, and was authorized by his Secretary of Defense Robert McNamara, as part of a total review of the US military. The name of the project refers to its number in the 150 review process.
The Shipboard Hazard and Defense Project (SHAD) was a series of tests conducted by the U.S. Department of Defense during the 1960s to determine how well service members aboard military ships could detect and respond to chemical and biological attacks. Dee Dodson Morris of the Army Chemical Corps who coordinated the ongoing investigation, says, "The SHAD tests were intended to show how vulnerable Navy ships were to chemical or biological warfare agents. The objective was to learn how chemical or biological warfare agents would disperse throughout a ship, and to use that information to develop procedures to protect crewmembers and decontaminate ships." DoD investigators note that over a hundred tests were planned but the lack of test results may indicate that many tests were never actually executed. 134 tests were planned initially, but reportedly, only 46 tests were actually completed.
