USS San Paulo
From Star Trek: Theurgy Wiki
The USS San Paulo was a Defiant class Federation starship operated by Starfleet in the late 24th century.
After the USS Theurgy discovered the conspiracy that compromised Starfleet and fled Federation space, the Encounter was selected to be part of Task Force Archeron and ordered to hunt down and destroy the errant carrier.
In early January of 2381, the San Paulo accompanied by the USS Bellerophon and the USS Akagi, engaged the USS Theurgy in a battle that resulted in the death of the Theurgy’s Chief Tactical Officer Augarath Thenaljpar.
In March of 2381 the Encounter was disabled by Lieutenant Commander Carrigan Trent's "Soup Sandwich" virus, but a week later had recovered sufficiently to participate in the Battle of Starbase 84.
(The USS San Paulo shouldn’t be confused with the USS Sao Paulo that was renamed the USS Defiant in 2375.)
