td aw. hb a. 4.11 TASK UNIT 11, UCRL ASSEMBLYA TU-11 was formed from a group of enginecrs and physicists to provide_a field capability for assembling and detonating th evices. They were members of the UCRL small weapons program wh were also responsible for the original design and fabrication of the three devices. A design and assembly team accompanied each device to the PPG. The use of C-124 aircraft for the transportation of the devices to Eniwetok allowed a maximum time for design and fabrication at Livermore and assembly at PPG. — The[— ei “\there were no delays caused by weather and the respective detonations occurred on the scheduled days: May 28, June 14, and June 22, 1956. ~ LL cf A second|_ The assembiy mission device was accomplished as a jointeffort of TU-11 and TU-12 UCRL. 4.12 T.:° r _\vas detonated on July 3, 1956. “-T 12, UCRL ASSEMBLY B Yie prime function of TU-12 was the field assembly _ The Task Unit was made up of A Division (Large Weapons) “and Device Engineering Division personnel who were thoroughly familiar with the devices from having followed them through their design and fabrication phases. These men were further subdivided into device assembly teams under the immediate control of the lead engineer for the particular device. This proved to be a highly workable system, Full trial assembly of cach device was made in the U. S. The, only compromise was that} . This assembly included matching support stand and local diagnostic equipment to “ou er ee the device. On some devices it proved cesirable to airship jigs, representing, and connccting points between, the device and cxternal equipment tied to the device, to PPG to facilitate carly completion of field diasnostic work, Another technique of value was the shipping of the devices in a nearly assembled condition -- that is, for shipment after final stateside assembly cach device was broken down as little as possible. - 158 - This enabled a rapid
