I photographed this Submarine Conning Tower in the Submarine Museum at Pearl Harbor
The museum signs indicate this was part of the WW II-era Baleo-class USS Parche (SS-384) that narrowly avoided being rammed during battle in 1944. Not to be confused with the Cold War-era Sturgeon-class USS Parche (SSN-683) that is displayed (the sail) in Bremerton
There is a page for the German U-Boat Conning Tower in Chicago
