I posted two days ago information from the AN/ARC-5 LF/MF/HF Components
Maintenance Manual AN 16-30ARC5-2
       ( http://bama.edebris.com/manuals/military/an-arc5/ )
Figure 8-55, that states:

"Receiver R-25/ARC-5 is supplied to the Service in quantities of one
for each five airplanes or one for each airplane depending upon the
type of aircraft in which this equipment is installed."

That implies more than one for each five aircraft in general service
use for aircraft carrying AN/ARC-5 MF/HF command sets.

There is yet another statement on this nine-page figure that states:

"A 1.5-3.0 Mc receiver (part No. R-25/ARC-5) is supplied in quantities
of one for each five airplanes.  This unit is not installed but is held
for the Service."

That implies that anticipated usage was infrequent and contingent.
I doubt any hard and fast one-to-five-airplane correlation to actual 
acquisition ratios of the R-25.

Most R-25 units that I've seen in the past forty years have been new or
even new-in-box, like the units that John Meshna was selling in the
mid-1970s.  Just like the R-24/ARC-5 BCB receiver, it appears that all
these common R-25/ARC-5 receivers and their associated T-18/ARC-5
transmitters found very little actual service use.
