Vreenak's shuttle
Vreenak's shuttle was a Romulan shuttle that was in operation during the 2370s.

In 2374, this shuttle transported Romulan Senator and Tal Shiar vice-chairman Vreenak to a high-level diplomatic meeting with the Vorta official Weyoun, on the planet Soukara. 

During his return journey, Starfleet Captain Benjamin Sisko convinced him to make a secret detour to Deep Space 9, in order to view supposed evidence of a planned Dominion invasion of Romulan space, in hope that Vreenak would instead convince the Senate to join the war against the Dominion.

While visiting Deep Space 9, the station's resident Cardassian, Elim Garak, then allegedly took the opportunity of Vreenak's visit "to make a quick search of his ship's database [...] for any intelligence information he may have picked up on the Dominion in Soukara." 

Vreenak's shuttle was subsequently destroyed while en route back to Romulus, due to an act of sabotage by Garak, effectively turning the Romulans against the Dominion, as it appeared that the Senator had been assassinated by them. ()
