The Chilean submarine O'Brien was an Oberon-class submarine in the Chilean Navy.

Design and construction[]

Main article: Oberon-class submarine

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]

Operational history[]

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

Decommissioning and fate[]

The museum in 2019

O'Brien and sister boat Hyatt were replaced by the Thomson-class submarines.

She is now permanently docked in the Chilean city of Valdivia where she is open to visitors as a museum ship.[4]
