MKUltra Subproject 42

Subproject 42 was set up to keep running a set of testing facilities. It continued the work of an earlier job, Subproject 16. The facilities were used for the realistic testing of certain research and development items of interest to the CIA's Chemical Division. Under Subproject 42, those facilities were to be moved to a new location.

A later memo describes how the trials went. In the past year, a number of "covert and realistic field trials" had been carried out. The results gave factual data needed to plan a number of operations. More trials were needed because TSS programs were producing new materials. The record points to a special interest in delivery systems, meaning the means of getting a material to its target.

The work was led by a man described as a seaman, whose name is blacked out. Dr. Sidney Gottlieb signed the establishing memo as chief of the Chemical Division. One memo set the cost at $8,300 for a year starting in March 1955. A later memo continued the project at $5,000 for a six-month period.
