Ship project history: Submarines were projected under Chilean order on the basis of first post-war British submarines of O class. Saddle-tank hull. Boats differed in the big sizes of fin structure on which 120mm/45 Vickers-Armstrong Mk E gun was installed in rotated semi-turret. Using of this gun on Chilean submarines was unique: similar guns have not found service on British submarines because of separate loading. All three submarines arrived to Valparaiso 5/3/1930.

Modernizations: None.

Naval service: Capitán O'Brien after write-off foundered at Talcahuano in 1959 and was salvaged and broken up only in 1988.
