[Milsurplus] Was Pearl Habour a joint Army-Navy Command?

[Henry Mei'l's]

When I brought up the anniversary date, I was wondering what the command and organizational structure was in 1941. Also, did Naval aircraft also utilize land based (AAF) facilities?
What were the communications structure, in terms of frequency allotments inter-service communication, type of radio equipment used and the like?

I've read some stories about army radar picking up the incoming Japanese aircraft.

Who, which service, if it was not equally shared, had the top level command ?

I'm sure I could dig much of this up on the internet, but I have the impression that not so few here
on these reflectors have personal knowledge of these matters.

My apologies if my query is too comprehensive.
