The U.S.S. Voyager NCC-74656-J was a 32nd-century descendant of Captain Janeway's famous ship. It followed a similar design, but had detached hulls and warp nacelles and used programmable matter. It also acted as the tested for the Pathway drive, which worked without dilithium.

The ship was designed by Ryan Dening. The producers wanted it to be a tribute to Janeway's ship and to show the links between different eras of Star Trek.

The model is part of Master Replicas new range of 4 to 5-inch long die-cast models, and is accompanied by a 48-page book, which features a brand-new, in-depth interview with ,em>Discovery showrunner Michelle Paradise.
