UNSC Lancelot

The UNSC Lancelot was a Destroyer in the UNSC Navy.

Background
The Lancelot was one of the four dozen vessels present during the second Battle of Sigma Octanus IV.

Battle of Sigma Octanus IV
It was seen by Commander Jacob Keyes charging straight into the Covenant fleet. Its fate is unknown, however it is highly likely that the ship was destroyed because a single UNSC Destroyer most likely won't survive a head on clash with a Covenant fleet. If it survived the battle, it is highly likely that the vessel was later destroyed during the Battle of Reach.

Trivia

 * The ship was named after Sir Lancelot, a knight of King Arthur's Round Table.
