The nuclear engineers who run the Nimitz's nuclear reactors
Well thanks for the compliment but we guys who ran the Navy's nuclear reactors weren't given any diplomas or academic degrees for completing Navy Nuclear Power School.
As for meeting with the Manhattan Project people and explaining things I guess I could have informed them that the bomb is going to make a really big
BOOM
but I don't expect Gen. Groves would have given me a plane ride to Los Alamos to deliver that earth shaking piece of information.
BTW, what would Chester Nimitz have to do with anything? It's not as if the Navy would replace Husband E. Kimmel after achieving "a major victory for the US."

It's easier to be an individual than a god.

Stopping the attack on Pearl Harbor would have been a major victory for the US. All 8 battleships would have been combat ready on Dec 8, 1941 rather than 4 sunk and 4 others damaged.
It's debatable how long the Nimitz could have been combat ready as fuel their aircraft needed wasn't readily available in those days. Even if Nimitz just sailed into Pearl after averting the attack they could have had a huge impact.
The nuclear engineers who run the Nimitz's nuclear reactors could just meet with the Manhattan Project scientists and explain to them how to do stuff that they wouldn't otherwise develop for several years.
The commander and other history minded types could meet with leaders like Nimitz/MacArthur and tell them about Japanese strategy and future plans that we only know because of history. "Attack here, don't bother with there, there is a fleet building up over in this area."
Obviously after stopping Pearl Harbor the butterfly effect would start to take effect but if they could smash the Japanese supply lines/war machines in the early months of the war it would have been over much sooner.

The Nimitz would have won the war within a month. There's absolutely no doubt in my mind about that. All you'd need would be the nuclear-powered aircraft carrier itself, which is designed to go months (if not years) at sea; and then just a handful of aircraft. You could cannibalize the machines to keep a few of their airworthy while at the same time dumbing-down the armaments. An F-14 could be rigged up to drop a couple of 1941-era bombs, for example. Nothing the Japanese had (and recall they didn't even have radar) would have been able to stop an armed F-14 flying at the speed of sound. We would have known where their fleets were and we would have sunk their ships the minute the Nimitz steamed into range. It's like being the only guy with a rifle in a battle fought by swordsmen. Plus I don't know whether the Nimitz was carrying any nuclear warheads in the movie, but it would have been able to greatly speed up the US nuclear program. We would have had the bomb by 1942. So even if the Nazis refused to believe what was happening to the Japanese was real, and kept fighting, we would have nuked them.

Forgive my ignorance if this has been stated, as I don't have the desire to read every response to the original post. My opinion would be that you are looking at it all wrong, yes the advanced weapons would be nice for a short while, and while they would eventually run out, what they would have is MUCH more importantknowledge. As Sheen said in the movie, they would know 40 yrs worth of mistakes to avoid, they would know every turn every country would make. As long as they were careful to not drastically alter history, but simply counter move every move of their opponents with precisionit would have been a much more mild war.

sailing around trying to find something to do and being spotted by aircraft from ENTERPRISE (CV-6) which was nearby on that day.
Actually it would be more likely he would have come across Rear Admiral Newton's USS Lexington, that Halsey's Enterprise.
Enterprise, while closer, was to the West of Oahu (returning from Wake), and after the attack, and searched to the south of Hawaii looking for the Japs.
Lexington on the other hand was to the Northwest, en route to Midway. They turned around after the attack and searched to the North of Hawaii (which is where the Japs and USS Nimitz was).
Lucky for us Lexington failed to locate the Japanese during their retreat.

Actually these were all branded as conspiracies, and the military discredits anyone that challenges the group decision making you're a victim of.

None not one of the claims you make are a part of those "conspiracies proved true".
And because some conspiracies are proved true does not mean all conspiracies are and will be proved in time.
Additionally every one of those "proved true conspiracies" fall into one of several categories.

1. normal criminal conspiracies. Not nutcase pseudo-science "grand conspiracies". The one about the Mafia for example
2. Not conspiracies at all. just programs that were classified at the time and later declassified after the need for secrecy was over. Manhattan Project and Operation Paperclip for example.
3. Still not proven and still bullsh!t. Its the same BS arguments made to "prove" their crap theories as have always been claimed by conspiracy sites. Infowars is a conspiracy site.

If you quote infowars, you've already lost.

Your "Critics" are not professionals in the field.
Your assumption and evasiveness tactic.
armchair commando internet conspiracy nutjobs with zero understanding of wtf they're talking about. Like YOU.

And againI don't agree with your characterization of the technology in question since critics point out that underwater technology was also developed under this program, but obviously we'll never agree on that.

The HAARP site is a landlocked facility in the middle of Alaska. It has no connection to any oceans, nor does any of it's research have anything to do with water. Those are fraking FACTS, you dumbass.

You posted your comment on the wrong thread, but I'll assume that was intentional since you're a comedian sailor.
And againI don't agree with your characterization of the technology in question since critics point out that underwater technology was also developed under this program, but obviously we'll never agree on that.
Again accounts of ship location based on reported directs in history is a subject we can agree on.

Oh you finally agree that an Ionospheric research facility using high frequency radio transmissions into the upper atmosphere has nothing to do with sonar and hurting sea mammals.

We found something we can agree on.
lol

OK. Still, it would have been interesting if Yelland had to explain his presence.

Owens position information was where the Japanese were in relation to Nimitz, not Hawaii. The Japanese aporoached Hawaii from the north.
The Japanese being Northwest of Nimitz means that Nimitz is somewhere East and north of Hawaii.
Enterprise was to the Southwest of Hawaii

I thought Nimitz was to the west or southwest of Pearl since Commander Owens told Captain Yelland the Japanese were,
"off the scope but an educated guess would be around about here. They'd have to be here up around the Northwest sector."
See 44:50 into the movie. Captain Yelland then sent the E-2 there to search.
But, maybe not.

Enterprise was no where near the area that Nimitz was in.
Nimitz was North of the Hawaiian chain, along the approach route of the Japanese fleet.
Enterprise was to the Southwest, returning from Wake.

Can you imagine Nimitz being spotted by search planes from Enterprise (CV-6) which was on the area. Let's see Captain Yelland explain his presence to Admiral Halsey who was aboard "Big E."

I would assume that the complete truth would be the best approach. The truth that they existed formerly in 1979-80 and through some unknown phenomenon ended up there. They would have all the physical evidence on hand that the leaders in 1941 couldn't deny. The knowledge they could supply of historical events that were set to transpire for the next 4 years would be invaluable.

I wonder how long the Nimitz would act independently, doing whatever Yelland ordered verses reporting to the U.S. government at that time and then taking directives from President Roosevelt and the current Naval leaders? Would they have stayed hidden, doing what they thought best or would they have sailed to Pearl or the U.S. West Coast and reported their existence?

The butter wouldn't melt, so we put it in the pie.

Please explain?
