It was November 1960 and I was a Seaman aboard USS Vega (AF-59). We were participating in a Naval Exercise involving several other ships in the Philippine Sea about midway between Okinawa to the North and Luzon, Philippines to the South. I was at the time a new Radar Operator in our Combat Information Center so had an opportunity to observe radio communications with our ship and the Task Force Commander who was on one of the other ships. Each ship for the duration of the exercise was assigned its own unique radio call sign and the Task Force Commander had been assigned the call sign "Jehovah."
At that time I was about 11 months into Active Duty with the U.S. Navy as a Naval Reservist making my escape from recent past association with the Jw's so I remember thinking, how strange to discover that the Navy made use of the name too.
