I have no idea but with the MR2 came more sonobuoys and more channels and therefore a more complex signaling system, so maybe the concept of an ordinance man was thought prudent. Just like the USN except we would use a sensor op.
Always though R stood for Radio. Rupert? Surely not, that was used instead of 'Roger' if you were feeling really bored.
Did have a Nav who had problems with his 'R's, always wanted the pilots to turn left for some reason.
I do remember there was talk that with the dry men just moving from ESM to Radar there was no chance for a break and concentration levels would fall, maybe that was it.
