In 2287, the Stealth was commanded by Vandor. This ship was dispatched by the Andorian government to represent their civilization at the opening of a rift in space and a diplomatic contact with the Calligar, a people on the other side of the galaxy.
The Stealth was specifically ordered to the event on the revelation that Thak, an Andorian ambassador sent by the Federation was being held as a hostage of the Calligar as a result of Commodore José Tyler offering diplomatic sanctuary to the Calligar Ecma. As such, Vandor demanded that Commander Hikaru Sulu, commanding the USS Enterprise-A, allow the Andorians to participate in reprisals against the Calligar. Vandor insisted that, since their diplomat was taken prisoner, they had the right to dictate terms. Vandor's call to action was challenged by Sulu, as well as by Captain Khund, of the Belligerent, who demanded that the Tellarites take control of the situation, as a Tellarite diplomat was also a prisoner.
The controversy was settled after Sulu's refusal to act was backed up by Ambassador Robert Fox, who threatened to demote the commanders of the opposing vessels to command of a lithium cracking station on remote Delta Vega. (TOS novel: The Rift)
