Rigellian scoutship
The Rigellian scoutship was a heavily-armed starship used under the authority of the Rigellian Trade Commission during the mid-22nd century. As scouts, these starships had small crew complements of around seventeen.

In late-2154, a Rigellian scoutship was attacked by what appeared to be the United Earth starship . The scoutship was able to inflict moderate damage on its attacker, and transmit a distress call, before being destroyed.

Following the incident, the Rigellian Trade Commission recognized the attacking vessel, and demanded compensation from Starfleet and the arrest of Jonathan Archer, Enterprises commander, for the loss of their vessel.

It was later determined that the attacking vessel was actually a Romulan drone ship holographically disguised as Enterprise. ()

Rigellian scoutships also existed in the mirror universe. One of these vessels was destroyed by the  sometime prior to 2155. ( opening credits)

In an alternate 2165 this type of vessel was included in the Earth convoy destined to settle on Ceti Alpha V. ()
