[Milsurplus] Arinc history

[Jack Antonio]

The Navy used the WE-233 early on, and when the JAN designation system
came out around early 1943, they gave it the ARC-4 designation. All the
manuals I've seen carry both designations. IIRC, the AN/ARC-1 started
entering service sometime in 1943.

It was always curious to me, knowing the military bought commercial
off the shelf radios for usage, why some sets wound up with a military
designation, and others retained their civvy designation in service.

For example, the Bendix RTA-1B received the designation of
AN/ARC-9, but the Bendix TA-12 did not receive any military nomenclature
that I'm aware of.
