During my time playing the Fallout series I have read up on a spacecraft that was supposedly built before the bombs fell. It was meant to be used to carry and transport high ranking officials across space in search of other life-bearing planets. It was supposed to be top-secret and if I am correct, the funding was cut because of the Great War. I think in the next Fallout it should be in a DLC or the be the main story to find this beast and discover the secrets and history of it.

Spoiler

"The U.S. government's real plan to survive a nuclear war was simply to find another planet to live on after blowing up this one. A spacecraft designed to ferry the human race to another planet was either under construction or ready to go before the War. The plan was for the government to flee to the oil rig, and then leave in a spaceship for another planet.[2]
Any voyage to space or recolonization of Earth would have been very difficult and fraught with unforeseeable complications. Thus, many of the Vaults were designed to have some sort of critical flaw in order to test how an average American would be able to deal with various circumstances. Vault 12 in Bakersfield had a faulty Vault door that wouldn't close all the way, allowing dangerous radiation to leak in, leading to the creation of California's ghoul population. Vault 15 was built normally (the rock slide that buried its control center was accidental), but was populated with a diverse mix of races and people to see what sort of tensions arise when varied backgrounds are packed into a small environment. Vault 13 was intended to stay shut for a full 200 years to test the effects of long term isolation. Vault 101 was to be sealed permanently to study the evolution of small communities in complete isolation from the rest of the world. The types and purposes of the experiments go on.
Eventually, due to either a change of plans by the Enclave's leadership or the spacecraft being destroyed, the Enclave abandoned their initial goal of settling on another planet, and decided to resettle the one they already had, although the Vault monitoring and research continued as the Vault Behavioral Project."

Can I get your ideas for this?

Ideas for future Fallout games go here http://www.gamesas.com/topic/1352810-fallout-4-speculation-suggestions-ideas-thread-54/

I think we need to wait for FO4 to come out before we start thinking up DLC ideas for it.

Unless you're seriously telling gamesas that you're willing to have these ideas to NOT be in the base game and SOLD as addtional content.

Also, they already DID put that idea of yours in-game. In New Vegas. In the base game. And it was instead used by a bunch of Ghouls.

I probably should have waited to know more about Fallout 4 before posting this, but if the plot involves more technological groups like the BoS or the Enclave, this would be a good idea or suggestion for the actual plot of the next game or a good DLC with the similar value of Old World Blues.

No, it's not. THe poster above mine linked you to the FO4 suggestion thread.

Here is the thing. All the info you based your DLC idea on isn't even canon. So basing anything on it would be stupid. Also yeah we need a Fallout 4 before we have DLC ideas for it.

Yep
