Two ships in the Star Trek
universe bore the name of U.S.S. Grissom.
The first U.S.S. Grissom was an Oberth-class science research vessel with the registry number NCC-638. It was commanded by Captain J.T. Esteban and was sent to investigate the Genesis Planet in 2285 with a team including Lieutenant Saavik and Dr. David Marcus, Captain Kirk's son. The Grissom was destroyed by a Klingon ship commanded by Kruge.
The second ship with the name Grissom, registry number NCC-59314, was near Sigma Erani around stardate 43872 and ordered to stand by to bring more hytritium from that system to help neutralize Beta Agni II's tainted water supply after half of the intended load that was going to be brought aboard the U.S.S. Enterprise exploded in a shuttle craft which was supposedly carrying Lieutenant Commander Data.
