Delta IX Rocket

In 2020, the  was commissioned by the USSA. The Delta IX Rocket was the last of the manned rockets to the Moon. Almost 15 years later, the all 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.

Appearances
The  is mentioned in Fallout 3's Museum of Technology on a description plate. There is also a crashed Delta IX rocket located in Vernon Square, near the entrance to the Statesman Hotel. One theory is that the rocket was fired against China during the war and was aborted (or failed; this is unlikely considering the Delta IX's perfect safety record)
