This is the Forward Observation Lounge as seen in Star Trek V: The Final Frontier modeled to fit Round 2's 1/350 Refit Enterprise. No one really knows where this room goes, though some think it may be in one of the two sets of forward windows on the saucer rim. Wherever you put it, no Enterprise-A build is complete without it. Where else are you going to release your pain?
