The USS Carrizal was a Starfleet starship which scanned Romulus, thus begining the Earth-Romulan War for the Romulans. This ship was commanded by Captain Dini. Mike Maliani was the astrogator on this ship at the time of the offense. (TOS novel: The Romulan Way)
- The Carrizal was described as a Federation starship at the time of its debriefing upon return from its mission. While this seems contradictory with canon, where the Romulan Wars were fought between Earth and Romulus, before the Federation formed, it could be assumed that the ship was originally a United Earth ship that came under Federation authority during the course of its mission, meaning it was an Earth vessel when it contacted the Romulans, and became a Federation ship later when it made the report.
