The ill-fated U.S.S. Defiant is from the third-season episode The Tholian Web and celebrates the 45th anniversary of the original Star Trek television series. Based on a 2006 Keepsake Ornament of the U.S.S. Enterprise, it features luminescent paint that allows the ornament to glow green in the dark as seen in the fan-favorite episode.
Curiosuly that will be the second glow-in-the-dark Defiant relased this year! Following from Round 2 Models' model kit release.
