The USS Burnell receives shuttle ECV-197-1 of the Orville and takes Captain Ed Mercer and Heveena to the Planetary Union Council on Earth. The ship is probably named after Jocelyn Bell Burnell, co-discoverer of the first radio wave pulsars.
USS Chanute	Unknown	Planetary Union	Unknown	Active (2419)	Old Wounds (mentioned only)
First Officer Kelly Grayson mentions a Lieutenant Commander Murphy serving aboard the USS Chanute in September, 2419. The ship is probably named after Octave Chanute, hailed as the father of aviation.

At an unknown point between 2413 and 2418, Bortus was assigned to the USS Clemens. Klyden, his new mate, accompanied him. They lived together aboard the Clemens for the duration of Bortus's assignment.
CCV Hawking^[1] (CCV-956)	Unknown	Planetary Union	Cruiser-class vessel	Destroyed (2420 or 2421)	Identity, Pt. 2 (mentioned only)
Destroyed by the Kaylon during the Battle of Earth in either late 2420 or early 2421.^[2] The ship is probably named after physicist Stephen Hawking.

A Vega Mining Consortium ship intentionally destroyed by the time-traveling antiques seller Pria Lavesque. After landing the Horizon onto the surface of a star-bound comet, she tells the USS Orville she had spent the last of her fuel fleeing a Krill battle cruiser and landed on the comet in an attempt to collect dysonium. It is unclear if this ship was from the 29th century and disguised as a 25th century mining vessel.

In an alternate timeline where Ed Mercer never became captain of the USS Orville, Ed and Cheva applied to be captain of the USS Sagan around 2420. Ultimately, Cheva won the position. This ship is likely a reference to popular scientist and author Carl Sagan.
