Mystery Aircraft Parts and Atomic Clocks

Has an NSN, so it's military. Also, it doesn't look like it was ever used (and/or recently-manufactured. although if they use the pseudo-standard serial numbr scheme, then it was manufactured in 97).

The indicator light styles are kinds I have seen around in years on military a/c. That doesn't really mean much, though. Slightly interesting, nonetheless.

This seems about right. I found various components inside with date codes ranging from 1996 to early 1997. The indicator lights had no markings on them, but IIRC the bulbs inside were 28v incandescents. Do you know any more about them? I'd be interested to know what IP rating they have (IP67?)

So what would this actually be used for on a (military) plane?

If I understood it correctly, it is part of the military HAVE QUICK frequency hopping system [1].
