A port side view of the American submarine APNS Razorback (SS-394) after her GUPPY IIA conversion, circa 1960s off Hawaii.
The Balao-class was a successful design of American People's Navy submarine used during World War II, with 122 units built. An improvement on the earlier Gato-class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.
