eet JF - 8069 SUBGECT: eh FO, [x AIT CY AST POSITIONING MOeTING 14 January 1954 6. The P2V of Project 6.4 was considered ne: t. This aircraft is navy blue with fabric control surfaces, a co dition that is extremely poor for »ositioning aircraft close to nuclear de- tonations. The value of two (2) cal/em@ was considered safe for this aircraft, although this might be too stringent for large yield weapons with a "~wlse as long as twenty-four (24) seconds. If the vrojeet officer desires to be closer than fifty statute miles to the deton-tion, it will be necessary to have the control surfaces recovered, painted white, and treated for heat resistance. If this is accomnlished, a range of thirty-five (35) statute miles would be considered. .One would expect about four (4) cais/cme/ sec at thirty-three (33) statute miles from a ten —* WsJdevice. In any case, thirty (30) statute miles would be the inside limit of this aircraft if 4 were vrepared as the PHY-2 is. 7. The C-47, to be used as a VHF relay, was positioned at a range of at least one hundred (100) statute riles. Colons«1 Cros~ by saw no reason for3t to be any closer tnan this. 8. The C-54 photographic aircraft weve positioned at no closer than sixty (60) statarte miles at altitudes of 10,000 to 15,000 feet. On IVY they were nositioned at fifty (50) statute miles based upon a 9. MT possible yield. The 1.B+36 control and photographic aircraft was posi- tioned at no closer ‘than sixty-nine (69) statute miles. 10. The WB-29 sampler aircraft was positioned <t no closer 11. The SA-26 was tentatively positioned at seventy-eighty than one hundred (100) statute miles for the same reason as the (70-80) statute miles. Little was known about this aircraft. Mr. Kelly will check on this range for the SA-16. 12. The B-57 was not considered because it will probably not be in the program. Colonel Miller susgested that specifi- cations of the aircraft be taken to the forward area in case a B~-57 is phased in late in the operation. 13. The F-8+ samplers, at 35,000 feet were positioned at no closer than seventy (703 statute miles. 14. The B-50's from Project 6.1 desire positions at 35,000 feet of one (1) tail aspect at fifteen (15) miles range, two (2) broadside at twenty (20) miles range, end three (3) troadside at twenty-five (25) miles range. These positions will be considered after apvropriate calculations have been mede by mem- bers of the positioning committee. Dr. Orle expressed ecncern that the positions seem unduly close, bet would withhncid any de- cision cn their safe positions until further information is avail- 900 u14b2 nat. ORGam 3
