I came across this photo at the Naval Historical Center website. You can see a larger version by clicking on the photo. In the center is Admiral Thomas H. Moorer, who was the Chief of Naval Operations (Designate). To his left is Vice Admiral William E. Gentner, Jr., who was Commander of the U.S. Taiwan Defense Command and to Admiral Moorer's right is Admiral Feng Chi-chung, Chinese Navy Commander-In-Chief. The photo was taken on 7 July 1967.
I previously posted what I believe to be a fairly accurate listing of Air Force generals who served at USTDC Chiefs of Staff, but I've never been able to locate information about Navy admirals who served as USTDC Commanders. If anyone knows where I can find such a listing, please let me know.
