For our Monday morning dive, we headed over to the USS Pilotfish submarine. The USS Pilotfish (SS-386) submarine was submerged in 52 metres of water and moored at a keel depth of 17 metres, approximately 275 metres from the point of the "Test Baker" underwater atomic blast on 25 July 1946. The USS Pilotfish lies with a 30-40 degree list to port, with the stern partially buried in the sand. The plating between the frames of the after torpedo room is dished to a depth of about 150 mm. The superstructure and tank tops are also dished in several places, and the superstructure plating has numerous tears and holes.
