NEVADA TEST SITE
Stokes, 12th scheduled full-scale test in the summer, 1957, series, is now scheduled to be ready for firing at 5:25 a.m. Monday, August 5. The experimental device, designed by Los Alamos Scientific Laboratory, will be suspended from a 67-foot diameter balloon at a height of approximately 1500 feet above ground surface.
The detonation will be in Area 7B of Yucca Flat.
The probable yield of this experimental device will approximate nominal. 20 Kilotons
There will be 18 experiments on the sequence timer. Approximately 100 military observers from Desert Rock will be stationed at News Nob. A U.S. Navy blimp will be stationed in the Flat to continue effects experiments. No animals will be used in experiments..
Approximately 24 aircraft will fly effects, training, and support missions. Stokes shot is not one of those on the previously-announced schedual of shots open to on-site observation by news media.
If Shasta remains unfired through Sunday morning, there will be dual capability for sonsideration at the Sunday afternoon evaluation meeting. Although the designed yield of Stokes is somewhat higher than that for the 500-foot tower shot Shasta, Stokes because of its high detonation could be fired under wind conditions which would be unacceptable for a tower shot.
