USS Reliant (NCC-1864)

The USS Reliant (NCC-1864) was a late 23rd century starship. In 2285, while serving as a support vessel for the Federation's Project Genesis, the Reliant encountered Khan Singh, who commandeered the ship and attacked the USS Enterprise (NCC-1701), resulting in the Reliant's destruction. 

The port warp nacelle aboard the Confederation of Earth's HMS was destroyed on initial launch, an "homage" of sorts to the destroyed port warp nacelle aboard the Reliant in Wrath of Khan.
