James L, . Liverman -2- } ' aha : ftps vid This memorandum is to request your concurrence in principle in our continuing to evaluate the YFU option and specifically your statement as to whether we are justified in placing a ''hold" on the YFU-81 in expectation of funding as estimated above. Iam satisfied that the current concept is a sound one and that it is most unlikely that a satisfactory alternative will be found at significantly lower cost. With your concurrence to proceed, and with timely availability of funds, I believe that we can have a firm proposal in your hands by 15 August and a ship in operation 90-120 days after release of funds. Your early response will be appreciated. Mahlon Manager ce: W. W. Burr, EV, HQ H. Hollister, EV, HQ W. W. Weyzen, EV, HQ R. L. Watters, EV, HQ L. J. Deal, EV, HQ H, McCammon, EV, HQ H. G.
