During the early-2280s, Mr. Beach served aboard the starship during Reliant's search for a test planet for Project Genesis, a terraforming experiment which was under the jurisdiction of Dr. Carol Marcus.
He and the remaining crew of the Reliant were stranded on the surface of Ceti Alpha V when Khan Noonien Singh commandeered the vessel. The crew was later saved by the USS Enterprise, following the starship's escape from the Mutara Nebula. (Star Trek II: The Wrath of Khan)
Commander Beach was played by actor Paul Kent. According to the novelization of the film, Beach (nicknamed "Stoney") was the ship's helmsman, a function consistent with his gold uniform departmental patches seen in the movie. However, in the film he sat at the science station.
