The Capitan O'Brien class were three submarines built for the Chilean Navy in the late 1920s. They were similar to the contemporary British Odin-class submarines, but mounted a larger 4.7 in (120 mm)/45 deck gun and were slightly smaller.
Ships
All boats were built by Vickers in Barrow-in-Furness and commissioned in 1929. The builder's photograph of the Simpson gives the dimensions as 272 feet 9 inches (83.1 m) overall × 27 feet 6 inches (8.4 m) × 16 feet 6 inches (5.0 m), surface speed 15 knots (28 km/h; 17 mph) surfaced and 9.5 knots (17.6 km/h; 10.9 mph) submerged.[1]
