In 2020, the Delta IX rocket was commissioned by the USSA and constructed by REPCONN Aerospace The Delta IX rocket was the last of the manned rockets to the Moon. Almost 15 years later, all the remaining Delta IX rockets were converted for U.S. military purposes, and the crew and instrument sections were replaced with nuclear warheads. The last manned mission to the Moon occurred in 2052.

The Delta IX rocket, commissioned by the USSA in 2020, was the last of the manned rockets that sent our brave American Astronauts to the moon. The Delta IX was in use for almost 15 years before being converted for military use and having the crew and instruments sections replaced with a nuclear warhead. The Delta IX recorded over 77 successful launches, making it one of the most successful rockets in U.S. history.
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 2 astronauts for up to 24 days maximum. The longest recorded spaceflight in a Delta IX rocket was the 17-day Zeus 12 Mission to the Moon.
The Delta IX rocket is mentioned in the Museum of Technology on a description plate, next to a full-scale model of the rocket itself. There is also a crashed and radioactive Delta IX rocket located in Vernon Square, near the exit to the Statesman Hotel.
- The Delta IX rocket in the Museum of Technology has the present-day "Stars and Stripes" on the side, complete with the 50 stars and 13 stripes. The rocket in Vernon Square has the game version.
- The crashed rocket by the Statesman Hotel was supposed to be fired at China but malfunctioned and crashed by the hotel instead.
The Delta IX rocket only appears in Fallout 3 and is mentioned in Fallout: New Vegas.
