[Milsurplus] US Navy use of Rebecca

[J Forster]

Does anyone know if the US Navy used the Rebecca hardware (RT-1A/APN-2 &
BC-929) and if it was given a Navy three-letter designation?

The reason I ask is I've turned up a test set component with a
CPR-...... designation that looks a whole lot like part of the IE-46 TS
for the Rebecca-Eureka system. It could also be part of an UHF IFF
system though, hence the question.

Thanks,
