A Federation starship commanded by Captain Amina Ramsey, an Academy friend of Beckett Mariner who had risen quickly through the ranks while Mariner stayed an ensign.
The USS Oakland was the command of Captain Amina Ramsey in 2380. It features in the Lower Decks episode Much Ado About Boimler.
While Captain Freeman and her senior officers are away on a covert mission, Ramsey and several of her officers come across from the Oakland to run the Cerritos. Ramsey and Beckett Mariner were close friends at Starfleet Academy, and Ramsey hopes to recruit her as first officer. Mariner responds by acting incompetent, which puzzles and disappoints her friend.
During a mission to help the USS Rubidoux, which has been overrun by a spaceborne lifeform, Mariner drops the act and her real ability shows. She turns the job down all the same, saying she is not ready to leave the lower decks.
