Defiance 7 was a pre-War space capsule.
The space capsule was the vehicle with which Captain Carl Bell of the United States Space Administration (USSA) made his historic flight, becoming the first human in space, on May 5, 1961. This claim was disputed by both the Soviet Union and China. Captain Bell's flight lasted twelve minutes and seven seconds and made a full revolution around the Earth. Bell died when the capsule crashed on its return to Earth.
It is not possible to complete an orbit of the Earth in a "coasting" spacecraft in less than 89 minutes. Most likely this is a reference to a suborbital flight, and the mention of completing a full orbit around the Earth is either a writing error or, if canonical, a propaganda statement embellishing on the actual facts of the flight.
Defiance 7 is mentioned only in Fallout 3.
