Star Trek: Discovery U.S.S. Discovery NCC-1031-A Starship with Collector Magazine:
After its sudden and violent arrival in the 32nd century, the U.S.S. Discovery NCC-1031 received an extensive refit at the Federation's headquarters. Upgraded with futuristic technology over three weeks of engineering, it was recommissioned as the U.S.S. Discovery NCC-1031-A.
The Discovery's refit provided it with a cloaking device, incorporated programmable matter into each of its stations, and converted its warp engines to the detached configuration common to the 32nd century, allowing for greater maneuverability when in use. It also upgraded the ship's spore drive with a nanogel interface, allowing Lieutenant Commander Stamets to finally remove his cybernetic implants.
