Sikorsky S-61 (CH-3) rotor system

[Pioneer]

G'day gents

I'm aware that the Sikorsky S-61R (CH-3/HH-3) helicopter design was derived from it's S-61 (SH-3 Sea King) series; but can anyone confirm if the S-61R's main rotor system was like that of the S-61/SH-3's in that it was foldable?
The reason I ask, is to ascertain as to whether the S-61R/CH-3 would have been more storable aboard a ship?

The S-61R's rotors do not fold. The rotor is otherwise the same so it would almost certainly have been possible to put a folding rotor on the R Airframe but it wasn't done.

Thank you for the conformation TomS
I haven't been able to find such information

I found the statement here:

But that might not be definitive. I just noticed that they say the S-61R fuselage was non-waterproof, which is definitely not true.
