USS Kelvin

The USS Kelvin was a Federation scout ship, the first officer of which was father of the soon-to- be first captain of the USS Enterprise, James T. Kirk. The Kelvin was on a mission near the Federation-Romulan border when it was attacked by a massive warship from the future, claiming to be of Romulan design. The ship's captain was killed and most of the crew were evacuated, including Kirk's mother, who was pregnant with him at the time. Kirk's father, as first officer, was forced to stay behind and hold off the Romulans as long as possible to allow the survivors to escape.

Although Kirk's father died in the battle, eventually having to ram the Kelvin into the Romulan ship to disable its weapons, both Kirk's mother and her son were able to escape. She gave birth on the Medical Shuttle as it left the Kelvin, so Kirk's dad was able to hear his son before he died. Sweet.
