In correspondence from the AEC to its operations offices and to JTF-7 around the middle of Feb., the conference on and discussions of alternate methods and locations for weapons testing are addressed and the letter to JTF-7 indicates “the availability of the LSD to our contractors and laboratories is apparently A the principal mile stone in realizing a readiness concept of 5 months for an open J seas operation. If a particular LSD could be designated for our use now, early access to its drawings would be most valuable for design and engineering, planning purposes. Accordingly, it is requested CJIF-7 attempt to obtain designation and drawings of a particular LSD and forward the information to ALOO for appropriate desimination."
