Where is Spock? Based on Commander Kruge's personal ship seen in Star Trek III: The Search for Spock, the Star Trek III Klingon Bird of Prey Partial Cloak Ship Electronic Vehicle measures 12 1/2-inches long and sports a wingspan of 19-inches! Partially cast in translucent plastic to simulate a Klingon cloaking device, the wings on the Bird of Prey raise and lower so you can display it in flight on its Klingon-symbol stand.
