Chilean submarine Hyatt (S23)

The Chilean submarine Hyatt (S23) was an Oberon-class submarine in the Chilean Navy, originally launched as HMS Condell. She was the second Chilean ship to bear the name Hyatt, the first being a British-built Serrano-class destroyer. Hyatt was in service from the mid-1970s until the late 1990s, but was replaced (along with her sister ship O'Brien) by the newer Thomson-class submarines Thomson (SS-20) and Simpson (SS-21).

In 2003, Hyatt was sold, exported and scrapped at Puerto General San Martin near Pisco, Peru. This attracted some attention due to poor environmental processes during ship breaking at the site.

Hyatt is named for the American-born engineer Edward Hyatt, who died while serving on a Chilean warship during the Battle of Iquique.
