Corvallen freighter

Star Trek: The Next Generation
Episode: TNG 240 - Face of the Enemy

This Corvallen freighter-for-hire was part of a complicated plan to help Romulan Vice-Proconsul M'ret and his aides defect to the Federation.

Subcommander N'Vek destroyed the freighter, when it appeared that the captain of the ship was being deceitful about following through with the plan.
