The Navy cited a loss of confidence in Cmdr. William Bradley Swanbeck’s ability to command the Los Angeles-class fast attack submarine Montpelier when he was fired from his job in June 2018.
The Navy said little else at the time but at a special court-martial trial in Groton, Connecticut in December, the ousted commanding officer pleaded guilty to engaging in conduct unbecoming resulting from an “inappropriate relationship” with the spouse of an enlisted subordinate, according to results of the case released by the service.
Swanbeck’s civilian defense attorney, Robert Crow, declined to comment when reached by Navy Times.
Rear Adm. Stephen Williamson was relieved of duty in August.
Swanbeck was sentenced to a reprimand and a forfeiture of pay of $1,500 for 11 months.
He took command of the Montpelier in April 2016.
After he was relieved of command, Swanbeck was reassigned to Submarine Squadron Four.
The submarine warfare officer received his commission in 1999 after graduating from the U.S. Naval Academy, according to a Navy biography.
