To obtain further data for the particular developments involved, additional tests were conducted. Additional shots were also conducted to take advantage of recent weapon research within the laboratories and to meet the need expressed by the Department of Defense for early developmentof specified weapon systems. ~ Two of the ghots Hsted in the January-March report were eliminated, the BUCKEYE shot, Hsted as a contingent shot, and the demonstration shot PINON because of conflict of timing with the Geneva Conference. On cement 11, only two test shots remained for the HARDTACK series. These were -FIG, .

Future Weapon Tests Operation MI LLRACE, planned for the late fall of 1958 at the Nevada Test Site, is to consist exclusively cf underground shots. The schedule Ancludes five small diagnostic shots, one relatively deep undergroundshot of feee Lis =F to explorethe field of underground testing, and approximately eight safety tests, from which no significant nuclear yield is ‘ expected. Preliminary planning was started for Operation TRUMPET,tentatively scheduled for the spring of 1959 at the Nevada Test Site.

A prime contract for a 2-year period was awarded in June to the General Electric Company for the operation of the Pinellas Peninsula Plant near St. Petersburg, Florida. This plant, which produces external initiators for sealed-pit weapons, was formerly op=rated by General Electric under a subcontract with Sandia Corporation. Storage facUities. The AEC concurred with the conclusion of the report of the Joint Board on Future Storage of Atomic Weapons that existing National Stockpile Sites and Operational Sicrege Sites, and existing and planned Service Storage Facilities will be adequate to store the ertire national stockpile through June 1962. Ballistics test range. Negotiations were begun with officials of the Navajo tribe at Winslow, Arizornz, for lease of approximately 40,000 acres of desert land on the Navajo reservation for use as 2 ballistics test range. At the range, measurements would be made of separation characteristics of unarmed bombs and missiles from high speed aircraft and of trajectory 80 that separation techniques, weapon shapes, and other factors may be evaluated.
