Background
The name for this class was devised by the production staff and was revealed by Okuda in the Star Trek Encyclopedia. Production photos of this class appeared in the special features section of the TNG Season 4 DVD.

Studio model
The scratch-built "kit-bash" studio model of the pre-damaged Freedom-class USS Firebrand was created at Gregory Jein, Inc. by Jein and his staff for the "graveyard" scene that the USS Enterprise (NCC-1701-D) traveled through following the Battle of Wolf 359. Jein used the molds he had of the and the two-foot  studio models to cast parts for the neck and nacelle, respectively. The other parts he built from scratch. The model was from the start constructed as being pre-damaged. Michael Okuda recalled, "Freedom: Upon reflection, I think this may have been something that Greg Jein came up with for one of the kitbashes he contributed to either BOBW or Unification. I'm not sure which model this was, and I'm not at all confident that Fact Files checked with anyone." Apart from the Freedom-class, Jein also constructed the pre-damaged  USS Princeton for the episode, using his own production assets unlike Okuda, Sternbach, and Miarecki, who constructed their models from commercially available AMT/Ertl model kits (enhanced with miscellaneous other pieces and first built "intact" and "damaged" later).
