Quite possibly they might have been installed to other USAF fighters too. Allies considered having NDB on carriers unsafe, hence the YE. Also there is not much reliable NDBs available if you are flying over occupied Europe escorting bombers. Besides the bombers are doing the navigation for you.

Only at Pacific.

Here is some info about the YG (YE on previous pages)

YG there looks like roof top installation.

Here is the "pie" for YG, even the the pic reads YE. Text below the pie says "This is the shore-based letter sequence."

Notice that the bearings are already inverted here. In the YE example pie in the pdf guide, you need to figure out the correct +/-180 bearing yourself.

The shore-based stations used the same system except the sectors were always assigned the same letters. Pilots recalled the letter sequence using the following ditty:
