The Untouched Justice was a Assault Carrier in the Covenant fleet. It was part of a fleet that helped glass several human planets, including Reach, but was stolen by Sepratist forces when it was boarded above the Ark.
The Untouched Justice was first created in 2536, to spearhead an invasion fleet for the planet Orion-IV. It successfully led the invasion with it's sister ship, Blinding Wind. The two craft continued serving the Covenant throughout the war, eventually being part of the battle of Reach. The ships were then rotated back to High Charity, where they stayed until the Prophet of Truth led them to Earth. During the battle above the Ark, the Untouched Justice was captured by ranger elites, while it's sister ship was destroyed by Rtas Vadum's supercarrier.
