MCKINLEY, CURTISS, ALBEWARIE, and to a lessex,degree, in BAIROKO. a. Special AN/TRC-1 equipment was installed in MT. MCKINLEY, CURTISS, and ALBEMARLE to provide for high speed Radio Teletype commnications between these three major ships and also from the Flagship to the Joint Relay Station at Eniwetok. It is worthy of mention here that the Flagship acted as a relay station for all traffic originated by units afloat at Eniwetok. In this capacity as a relay center, she handled approximately 20,000 groups daily and a total of approxi- mately 1,200,000 for the operation. Also installed in the same major ships were teletype machines which were used in conjunction with Crypto System SIGTOT.
