It was actually Nimitz they wanted to slot in as Richardson's replacement.
Nimitz demurred, saying that there were dozens more senior than him and he didn't want to cause ill will in the navy by jumping over so many.
Then they went to Kimmel, who was even more junior, and part of why he got shafted so badly was probably due to having enemies in the navy.
By any military standard, Kimmel got rolled while MacArthur goy away with just about murder. Kimmel really couldn't have averted most of the Pearl losses, while MacArthur could have done so much to not have screwed up as much as he did in the philipines.
To be Fair, Kimmel did get more kicking than he deserved, but see below.
It's sad, really, Kimmel was by most accounts a very good admiral, which is one reason why he got the post OTL despite his lack of seniority. He just didn't have Nimitz's social savvy or King's political chops (let alone MacArthurs).
I guess it did work out OTL, because nimitz was a pure genius at placinh and managing capable subordinates, and was fantastic as a guy for the stay-at-home head honcho role.
Kimmel actually could have done three things.
1: Ammo stored and READY at the ADA, that he personally controlled.
2: NOT BE PREDICTABLE. I kid you not. This alone was why he deserved to be relived. His FltEx Schedule was like reading a train schedule run by the Germans. The Japanese pretty much made their entire plans based on that
they knew where the BBs would be at certain days.
3: Stepped up more aggressive and distant patrol with assets he personally controlled, and kept them out 24/7
In premise, taken the war warning 100% seriously, and acted (As Bull Hasley did) if the war was going to happen that moment.
Note I don't include more torpedo netting, etc, etc.
Now, to be fair,
even with the Fleet Problem that showed how vulnerable Pearl was to Air attack via carriers, I don't blame him for whiffing on that for following reasons:
1: No one
told him or his command about Japanese shallow water torpexes.
2: No one
in the US knew that Japan had solved the basic unrep problems to get a force
to Pearl.
(This is one of the reasons no one reasonably expected, and I do mean
no one an attack at Pearl. Intel hadn't found out Japan had solved fueling at sea across the board, and without that, Japan couldn't
get a viable strike force to Pearl)
3: Given 1 and 2, intel (both in WDC and in Pearl) reasonably (
with to be fair, good reason!) expected the blow against the US to fall against MacA, not Kimmel. Richardson was a prophet (and one reason why he was bounced, btw) that Pearl was a viable surprise target. No one took him seriously.
However, with 1 and 2 above,
and War Plan Orange (which expected the decisive naval battle AT Phils) which, ironically, was more or less the actual Japanese warplan UNTIL 1940, and Isoru's little brainstorm, no one in the various services or military expected Pearl.
So, Kimmel getting blasted as he did, yes, was a bit much. Doesn't make what he didn't do (two of which would have a chance to have prevented the damage) any less heinous.
