Gheb'shaat

The Gheb'shaat was a swift courier that saw service with the Romulan Star Empire during the 24th century. 

The ship was the personal transport of Senator Vreenak. In 2374, it was destroyed on its journey back to Romulus from a secret meeting with Captain Benjamin Sisko on Deep Space 9. The Tal Shiar blamed the incident on the Dominion due to the discovery of evidence that the Dominion was seeking to violate its nonaggression pact.

However, the true culprit was the Cardassian Garak who destroyed the ship and killed Vreenak as part of a plan to trick the Star Empire into joining the Dominion War on the side of the Federation and Klingon Empire.
