5.4 Operations from H-Hour to R-Hour 54-1 Transit Phase Control The P2V5 will keep Able and Baker on or near their H minus 2 station until shot time or a stated departure time after shottime. The P2V5 will do this by dialing the ships on a course that will generally orbit the H-2 station. Departure time will either be a predetermined departure time taken from Annex HM or will be determined from t elemetered data received by the Project Officer (CAPT Molumphy) and the Military Evaluations Consultant (Strope) in the P2V5. At this time the washdown valve will be remotely actuated by the Project Officer, and the washdown system on Able will commence spraying.' At departure time, the P2V5 will direct the ships on a course upwind into the contaminating event. At the same time the P2V5 directs Able and Baker into the conteminating event, it will dial the sinusoidal maneuver, and the automatic pilot aboard each ship will commence directing this series of course changes. 54.2 Shins! Location and Radiation Information In the P2V5, the Projct Officer and the military Lvaluations Advisor will maintain a continuous record of the position of the ships and the radiation intensities on each ship. Ships' locations will be determined by radar from the plane and radiation intensities will be gathered by multi~channel telemetering e quipment. 52403 Ship Recovery ST. LOUIS © ae The ships will be turned onto a course toward ‘IOLALA either (1) when they reach a point two miles downwind from the reef of Bikini Atoll or (2) when the general radiation intensity on Beker reaches 1000 r/nr, whichever occurs first, or (3) at the discretion of the Project Officer, It is anticipated that, in the case of (1) or (2), this time will be approximately H-plus-2. As soon as the shipsare clear of the contaminating event and are within range of HMOLALA (from 10 to 14 miles), control will be transferred to MOLALA. The P2V5 will be in voice communication with both MOLALA and TAIATONI at this time and will direct operations immediately subsequent to MOLALA's taking over control. it is desired to continue the washdown on Able, based on telemetered If intensity information received by the P2V5, MOLALA will direct Able on various maneuvers to ensure that all areas of the ship are wet by the washdowm, ‘shen Able has been sufficiently washed, MOLAIA will turn off the spraying’ array by remote control and the washdown pumps will pump overboarde Paker will also be controlled by MOLAIA, but will not continue to maneuvere TAWAKONI will approach each ship and the Radiological Safety Adivsor will conduct a raciological survey of the ship. As a resuit of these surveys, one of a mumber of courses of action may be followed, ail directed toward returning the ships to Eniwetok immediately and expeditiously. 009521 . 20
