General Description of Test Ships YAG-39, YAG-40, LST-611
Abstract
Former Liberty Ships YAG's 39 and 40 were modified for participation in weapons effects tests during Operations CASTLE and WIGWAM, and a third ship, the USS CROOK COUNTY (LST-611), was altered and joined the YAG's in Operation REDWING. The ships were rigged for remote operation from below-deck control rooms shielded from gamma radiation. Navigational, communication and engineering functions were performed from these secondary conn spaces. Instruments for the work of fallout collection, ship shielding data collection, water sampling, and ship washdown evaluation were installed so that all could be operated from the shielded spaces. All of the project instrumentation and project communications equipment were removed from the ships after REDWING, and additional modifications were made to the YAG's for their participation in a subsequent BuShips operation. Should these ships be used similarly in the future, of course, suitable project instrumentation would be necessary. Additionally, it is recommended that the radars be changed, at least on the YAG's, more air conditioning be installed, and the habitability of the shielded spaces be improved. The shielding factor of the LST control room should be further investigated and improved if necessary.
