We didn't justify
it we justified it wasn't bull.
There will be launch faculties, rocket launching areas, (like JFK space centre) with data, fuel, tech and maybe rockets.
He is able to find fuel for the rockets he constructs. On the subject of resources, just because a nuclear war happened didn't mean everything dissapeared , it means its harder to get the needed resources to get his plan working.
To be honest, he would probably use nuclear power not fossil fuels, fossil fuels went outta fashion in Fallout and was replaced by nuclear power.
REPCONN Aerospace rocket, representing a hybrid fossil fuel/plasma engine design. The former is used to break free of Earth's gravitational pull, the latter to bring the rocket to other planets for mining operations.
The rocket, developed entirely by USSA scientists, was a single-stage vehicle with an ejectable crew section or satellite storage bay. The propulsion system was a nuclear-electric derivative drive, using a massive electrical jolt to start the nuclear reaction on launch. The crew section was protected from the radioactive chambers by way of a massive titanium-vanadium disc. The spacecraft had the capability to sustain two astronauts up to a maximum of 24 days. The longest recorded space flight in a Delta IX rocket was the 17-day Zeus 12 mission to the moon.
So Repconn isn't entirely useless, and Rockets were very successfully developed and used by the USA.
With all the money from the casinos and manpower clogging up Freeside, House can effectively build up a workforce of technical specialists.
All he'd have to do is send enough people on rockets to these abandoned lunar facilities and get them working on making them operational. If he's lucky, he might scavenge information that could lead to him producing even more effective colony ships, but at the very least he has access to the Moon.
Access to the moon is certainly a key factor given:
House can produce a lunar colony that is viable and self-sufficient in most concerns. He'd still need salvage, but that is assuming he loses Vegas in the process of taking hold of the Moon.
We have undeniable evidence of a moon conflict from Fallout 4
The battle at the sea of Tranquility? Generally people dont tend to have battles, unless there is something there of strategic value.
Perhaps what it was about was just who can take control and colonise the moon first.
People in space suits fighting implies that there are military base camps on the moon. In fact, it would only make sense that there are landing camps and beachhead on there.
Considering this, they more than likely had lunar facilities to deploy troops/fighters to attack one another. If there are any leftover facilities, House wouldn't even need to start from scratch on Earth.
Spaceflight technology was a good deal more advanced than in our own world, they have SSTO craft, nuclear propulsion, and continued going to the moon well into the 21st century from the first touchdowns in the 1960's.
House tends not to promise unless he can deliver, and I doubt that has changed here.
He would not talk about taking rockets to the stars unless he knew there was a feasible way to do it.
You cannot deny House is able to get to the moon.
We managed it in the 60's with technology vastly inferior to what House has
So? They can survive without it, and it would affect House worse. Vegas's economy relies on tourism and trade, while he gets supplies from the NCR as well.
How exactly could they survive without it?
NCR relies heavily on the Hoover Dam, they would be in real trouble. anyway, I doubt NCR leadership would be in the mood to mess around with House after he is done with them. He could probably have them in his pocket anyway, like the Brahmin Barons do.
He could be a "wealthy donor" and then let them repay him by having them do his bidding, perhaps with the army, or something like that
A quick re-enactment:
NCR: Give us energy now! We have placed an embargo on New Vegas and stopped all trade!
House: Shall we do this the easy way or the hard way then?
How about 1 million caps and free energy for a month?
Or there is always me creating, or sponsoring and arming anti NCR terrorist groups, or even taking military action. You saw what happened to the Legion with my Mark 2 securitrons. I could invade your territory, go on mass murder sprees with my robotic army. I could slaughter them, my army is way superior to yours. My securitrons will destroy all outlying villages and brahmin farms, and all crop farms. Eventually you will starve out.
Or you could just trade and lift the embargo.
NCR: Ahhhhhhhhhhhhhhhh
