    Greetings. I am helping a friend research information regarding the WWII service career of his father. As a former Navy Machinist's Mate 3rd Class (MM3) and Lieutenant, I have a pretty good handle on most of the information, but this (presumed) specialty designator is eluding me.

    His father was discharged in 1946 as a Motor Machinist's Mate First Class (T) [MoMM1c(T)] and I have been able to help my friend learn somewhat what he did, working on Diesel engines [he attended Advanced Naval Training School (Diesel)] and Nordberg School [in Milwaukee]).

    But while I can find innumerable examples of MoMM1c(T), MoMM2c(T) etc. referenced, I have been unable to find anything that explains what (T) means.

    I did find that MoMM rating does have specialties, but none seem to relate to the (T): https://www.cem.va.gov/CEM/docs/abbreviations/Ranks_Navy.pdf among others references MOMMSR MOTOR MACHINIST'S MATE (SHIP REPAIR), MOMMSRD MOTOR MACHINIST'S MATE (SHIP REPAIR-DIESEL), MOMMSRG MOTOR MACHINIST'S MATE (SHIP REPAIR-GASOLINE).

    Thanks in advance, Dave.

    T is for Temporary. He had met the qualifications, but official approval had not come through yet.

    Takao, thanks! I would never have guessed that. So that would refer to his selection to Petty Officer 1st Class, correct?

    It's similar to "brevet". And when I was on active duty you could simulate that. When the rating tests were done the ones who passed were divided into four categories. The ones with the most points were promoted immediately. The other three were "frocked", meaning they could wear the rank but they weren't getting paid at that level yet.

    Exactly what I was thinking. In the Navy we called it "Frocked", which I'm sure is an old sailing navy term relating to a uniform frock. Thanks all.

    Correct.

    Sometimes, it took months for official word to come down, and sometimes the promotion was immediate.
