Fallout 2 makes it clear that the Oil Rig and Navarro are the only Enclave bases. The entire enclave command is on the rig. There are not that many of them in Fallout 2. The oil rig gets blown up, killing all of the Enlcave leadership and the bulk of the Enclave.
Fallout 3 which is only 35 years after the Oil Rig we see the Enclave in DC and they have thousands of people and countless Vertibirds. How did that happen? We learned that Raven Rock did not have anyone in it. Eden becomes president because he was the only one left.
Having Eden means that the Enclave in Fallout 2 knew about Raven Rock and its wealth of resourses and yet they did nothing from 2077 to 2241. That is along time doing nothing. DC had all that wealth, a space weapon and Optimus Prime which the Enclave would have known about for sure and yet they did nothing!. They could have taken back America from West coast and from the East coast at the same time and yet they did nothing.
How did they have such a huge population explosion in just 35 years? Now the problem becomes worse when you take into account of the events of New Vegas. In New Vegas we learn what happened to Navarro. Now remember Navarro did not have that many people, there were not thousands of people there and most of those that were there were not soldiers. Anyways Fallout 3 we learned that remnants under Augustus followed the radio signal from Raven Rock. In New Vegas we learned that people stayed at Navarro which later fell to NCR. Many tried to start a new life in NCR, only to be hunted down by the BoS and NCR.
So this means the small population at Navarro, split up and only a part of that small group went to DC and somehow managed to have thouands of people and all that tech? How?!
Why did they just not take back DC by force? Why did they try that stupid watered down/half baked plan of the one from Fallout 2. Insted of using Airborn modded FEV that would have killed everything on the planet in every nook and cranny. They went with the water born which would only kill people in DC and it all came down to "I hope the Lone Wanderer helps us with are evil plan."
Now the problem with that is... If they still had Modded Airborn FEV somehow taken from the Rig before it blew up. Why did they not just try it again? Why not just move to another spot and try the Jet steam plan again? How did they manage to keep a sample of the Modded FEV?
My theory is that the Outpost in Chicago was set up by Augustus on the way to DC as a relay and fueling stop. For the Enclave can't talk with Navarro directly and vertibirds can't fly that far without refueling and maintenance. I am hoping they made a deal with the MWBoS.
Another problem is how did Oil Rig and Raven Rock communicate?
