Design and construction
The submarine, built by Scottish company Scott Lithgow, was laid down on 17 January 1971, and launched on 21 December 1972.[1] The planned July 1974 completion was delayed by the need to redo internal cabling.[1] She was commissioned into the Chilean Navy on 15 April 1976.[2] The submarine was named after John Thomond O'Brien, who fought in the Chilean War of Independence.[3]

O'Brien was in service from the mid-1970s until the mid-2000s.
