In an emailed statement, Mr. Luckey confirmed that he was working on a defense-related start-up.
“We are spending more than ever on defense technology, yet the pace of innovation has been slowing for decades,” he wrote. “We need a new kind of defense company, one that will save taxpayer dollars while creating superior technology to keep our troops and citizens safer.”
The new business is the latest note in the charmed and very unconventional life of Mr. Luckey. He stood to receive hundreds of millions of dollars from the sale of Oculus to Facebook, he said in court in January during a trial involving a dispute between Oculus and a games publisher. The precise amount he left the company with is unclear.
He has accumulated a lot of toys with that Facebook money. Most of his properties are registered to more than a half-dozen companies that can be traced to Mr. Luckey through public business records. Many of their names, like Fiendlord’s Keep, Black Omen and Wings of Time, relate to a video game called Chrono Trigger.
Mr. Luckey, 24, lives in a 78-year-old mansion in affluent Woodside, Calif., with a group of friends, according to public records, and Facebook posts by his roommates. One of his roommates is his girlfriend, Nicole Edelmann, who has received attention for her support of GamerGate, a loose online movement that has sought to push back against social progressivism in video games.
Mr. Luckey and Ms. Edelmann are devotees of cosplay — short for costume play — in which people dress as characters from games and comic books. In May, they posed for photos at a cosplay conference in Japan dressed as a character from the game Metal Gear Solid, complete with identical bikini tops, ripped black tights and ammunition belts.
A person who knows him described Mr. Luckey as a casual “prepper,” someone who prepares for societal collapse, though another person said he was simply a military buff.
Among his assets is about 85 acres of property in upstate New York, including a luxury home built atop a decommissioned Atlas missile silo. Tax rolls for Clinton County, N.Y., list Oculus VR and Black Omen — which Mr. Luckey owns, according to California records — among the owners of the properties. Tenants live in the home.
He owns a second property in Chico, Calif., with decommissioned Titan 1 missile silos, according to records.
Mr. Luckey also owns several military vehicles and, through various companies, three helicopters, and he received a student pilot’s license last year, according to Federal Aviation Administration records. He recently purchased a marina in Orange County, Calif., where he grew up, according to public records.
While Mr. Luckey became a tech icon for reviving interest in virtual reality, his politics burst into view in September when The Daily Beast published an article saying he had quietly funded a pro-Trump nonprofit, Nimble America.
After the article ran, Mr. Luckey said on Facebook that he was sorry his actions were hurting Oculus. He said he had given the nonprofit $10,000 because he believed it had “fresh ideas on how to communicate with young voters through the use of several billboards.” He said news articles, some of which accused him of funding the creation of racist memes, had distorted his views.
