~12— funding under Vela Hotel. "This would include x-ray as well as gamma ray and particle background measurement using detectors, expecially developed for the purpose, at altitudes characteristic of both high and low earth satellites." Pertinent to the shift from readiness to Vela Uniform is the section: In connection with the device program and capability for readiness to test underground within 45-60 days was being approached in the spring of 1960. by the advent of the seismic detection program. This was set back Because of the seismic program it appears that the B tunnel will not be available for a readiness program, However, several sites in the E tunnel will be. The lab has in preparation a new proposal for a readiness program based on the assumption that the seismic program will be carried out." The lower level of activity and support for Plowshare is indicated noting that Gnome is the only nuclear experiment for which construction authorization exists and that funding reductions have caused discontinuation of high explosive studies and a reduced level of certain feasibility studies. "In the meantime, we are determined to make Gnome as successful an experiment as possible, believing that a single successful Plowshare demonstration may very well affect decisions on the budget and authorization." The next program letter came from Brown to Shute on 18 Jan. 61 and stated, "Since the moratorium on nuclear weapons testing has been in existence now for over 2 years, and may be expected to continue for some time in the future, the laboratories methods of weapons developments have had to be adapted to the situation. Very much more elaborate techniques of calculations and nuclear weapons design, along with a certain amount of laboratory experimentation have served as a partial substitute for weapons tests. The result has been very real and important but considerably diminished progress in weapons design and development. If testing is not resumed, we expect in the period thru FY 63 to proceed with
