Left to right: VADM Gentner, CNO ADM Moorer, Admiral Feng Chi-chung, Chinese Navy commander-in-chiefThe last time I updated my list of the admirals who commanded USTDC was in April 2008. Though I've have never found any historical documents that contain a complete list, I believe these are fairly close.
Today I found a Time Magazine article from April 1964 that described President Johnson's new top command team and one of those mentioned was Vice Admiral William E. Gentner Jr. (misspelled as "Centner" in the first sentence of the article). I believe that he was the third COMUSTDC.
The article describes VADM Gentner as follows:
Vice Admiral William E. Centner Jr., 56, new commander of the Taiwan Defense Command on Nationalist Chinese Formosa. A taut, efficient planner and a professional perfectionist, Gentner demands that his subordinates be thinking men as well as fighting men, regularly flew "guest lecturers" out to speak aboard the big carriers when he was boss of the Sixth Fleet. Though Bill Gentner probably won't need it, there will be plenty of advice available to him on Formosa. U.S. Ambassador Jerauld Wright is a retired four-star admiral.
Once again, here's the list of COMUSTDC admirals that I've been able to find. If anyone has any additions or corrections to this list, please let me know.
Vice Adm. Charles L. Melson 1962 to 1964
Vice Adm. William E. Gentner Jr. 1964 to 1967
Vice Adm. John L. Chew 1967 to 1969
