Capitan O'Brien class submarine
From Wikipedia, the free encyclopedia
The Capitan O'Brien class were three submarines built for the Chilean Navy in the late 1920's. They were similar to the contemporary British Odin class submarines, but mounted a larger 4.7 inch deck gun and were slightly smaller.
