For other uses, see Galahad.

The USS Galahad was a Federation starship under the command of Captain Joshua Grant in service in the 23rd century. The Galahad was involved in one of the most serious violation on record of the Prime Directive, with an unauthorized entry into the civil war on Shiva Omicron IV, where the Galahad stunned an army of the Jerion faction during an attempted massacre, causing the unconscious Jerions to be themselves massacred, eventually leading to the destruction of the Jerion culture. Captain Grant was court-martialed and imprisoned for his part in this genocide. The Galahad incident is used as a test case for measuring the competency of a starship captain. (TOS video game: Judgment Rites)

The ship was named after the knight of King Arthur's Round Table.
