gEigdBcenera netneene + JB II, A. THE MISSILE SYSTEM DESCRIPTION 1, The HARDTACK missiles will be of the tactical Redstone configuration, with suitable modifications to provide the short base-line trajectories and the high air-burst capabilities which are required for the operation, The guidance function will be utilized for the initiation of a properly timed cut-off signal for the rocket motor and the provision of the intelligence required by the arming system.# This differs from the tactical missile in which the range guidance function is wbilized for terminal guidance (during and following reentry), be retained as in the tactical configuration. Lateral guidance will Certain additional signals are provided to the Arming system, as outlined in Section ITI. 2. ‘Iwo new trajectories are being developed to allow the detonations to occur in the near vicinity of Bikini Atoll. Standard trajectories attain the required altitudes, but at distances from the launchpoint which would be excessive for the HARDTACK application. 3, The missiles will be completely assembled (including inert warheads) and ground tested at ABMA, Huntsville, Alabama, prior to air-lifting to the Eniwetok Proving Ground, This assembly will include interference testing of all components and handling equipment, and it is expected that it will duplicate as nearly as possible the procedures to be followed in the forward area. B, MISSILE (NON~NUCLEAR) SAFETY With the exception of the normal industrial safety hazards associated with this type of operation, the Redstone missile launchings present two hazards which are somewhat unique in character, These are offered, first, * There is one additional function assigned to the guidance system, in connection with the instrumentation for the firings. However, this function is in no way related to the behavior of the missile, and hence is unrelated to safety. RESTRICTED DATA ATOMIC ENERGY ACT 1954
