The U.S.S. Enterprise NCC-1701-C played a vital role in history when it sacrificed itself trying to defend the Klingons from a Romulan attack.
The ship never starred in a series of its own but was designed by Andrew Probert and Rick Sternbach to fill in a gap in STAR TREK's history. The Hero Collector model measures 5.5" (14 cm) long.
