I believe it appeared a couple of years after WWII, and then became the =
most common ADF in the US military for the next 15 to 20 years. =20

For the JAN nomenclature system, it seems to be a lot more reliable to =
sequence gear by the component number rather than the system number.  =
Thus, the R-5/ARN-7 ADF is definitely an early JAN ADF of WWII vintage.  =
The R-101/ARN-6 ADF came well afterwards, though the -6 would lead one =
to think otherwise.

Even that's not foolproof, though.  For example, the RT-246/VRC came out =
in the 1960-era, when other JAN RT- units were receiving numbers in the =
500 range (like the similar RT-524/VRC).  Most RT- numbers in the 200 =
range had been assigned about ten years earlier.  Also, it was assigned =
to the system AN/VRC-12 (among others), even though systems AN/VRC-13 =
though -22 had been assigned to completely different (and much earlier) =
gear by 1949.  Nothing like making a logical system inconsistent!

You have a great-sounding installation there.  Too bad you're not =
stateside!
