V29-321G Rocket

The  (nicknamed Big Fat Fiery Red) is a REPCONN Aerospace rocket and one of its many abortive designs. It became infamous after an incident which destroyed the launch site, although the company cheerfully deemed that an important lesson in creating explosion-resistant shielding for their rockets and launch sites.

Appearances
A rocket of this type is mentioned and its model appear in Fallout: New Vegas.

Behind the Scenes
The nickname is most likely a reference to the B-52 bomber which was often referred to as the Big Ugly Fat Fucker.
