The SS Peloponnesus (NGL-56434) was a Miranda-class starship converted to serve as a tiberium freighter for the Federation Merchant Service. Matthew Donahugh was born on the ship. His mother was the ship's commanding officer and his father was the chief medical officer. (Star Trek: Remington) Because of the long trips involved, Matthew's father often did not have access to large caches of medical supplies. Matthew, acting as his assistant, became an expert, even at his young age, at improvising medical techniques, a skill which helped him when he later became a doctor in Starfleet.
