Electronics Group

This group and the 013D Electronics Group in the Technical Director's organization (see the section on Nuclear Weapon Phenomena below) were one and the same. They performed a dual function in working for both the DSM and the Technical Director.

As planned initially in January 1946, this group's primary responsibility was to determine the damage to electronic equipment aboard ships after exposure to each detonation. After a series of meetings in February 1946, the group's responsibilities were significantly expanded. It took over electronic equipment responsibilities from BuAer and the Army Signal Corps. It assumed full responsibility for execution of electronics instrumentation projects as specified in the Instrumentation Plan (Annex G, Op Plan 1-46) and the Communications and Electronic Plan (Annex C, Op Plan 1-46). It carried out most of the studies associated with the electromagnetic propagation program and provided support to wave motion, blast pressure, shock, drone boat, and telemetering projects. As a result of all these added responsibilities, the size of the group was expanded and liaison officers from several other groups were assigned. Also because of these added responsibilities, the group became accountable to the Technical Director, although it maintained close liaison with the DSM.
