The three and a half month process of salvaging the Squalus was particularly arduous due to the operating depth of 240 feet. This forced the team to use the newly developed mixed-gas diving system, using a the highly modified Mk 5 deep water diving dress. 628 dives were made to rig lifting chains under the hull and attach pontoons. This photo shows a lifting attempt on July 13, 1939. Unfortunately, the boat rose uncontrollably with the bow breaking the water before the boat slipped the chains and sank back to the bottom. 20 more days were needed to re-rig the chains and pontoons. The boat was brought to the surface in a series of controlled lifts and she was towed back to Portsmouth, hanging from the pontoons. Four enlisted divers were awarded the Medal of Honor for their actions during the rescue and salvage phase, and one officer was awarded the Navy Cross. A truly great effort indeed. | |||

Rescue Operations

The McCann chamber alongside the Falcon as it prepares for a dive on the sunken Squalus, May 24, 1939. A total of five trips were made to the sub, under very difficult conditions. At one point, frayed cables trapped the chamber underwater and a rescue of the rescuers was needed. All 33 men in the forward compartments were returned to the surface.

Rescued crew on the deck of the USCGC Harriet Lane. The Squalus' Commanding Officer, LT Oliver F. Naquin, is standing hatless in the center, between the lifeline and the sailor behind him. He was the last man out of the boat. His calm and decisive demeanor provided courage and hope to his crew while they awaited rescue. His leadership was outstanding.

Salvage Operations and the Return to Portsmouth
The three and a half month process of salvaging the Squalus was particularly arduous due to the operating depth of 240 feet. This forced the team to use the newly developed mixed-gas diving system, using a the highly modified Mk 5 deep water diving dress. 628 dives were made to rig lifting chains under the hull and attach pontoons. This photo shows a lifting attempt on July 13, 1939. Unfortunately, the boat rose uncontrollably with the bow breaking the water before the boat slipped the chains and sank back to the bottom. 20 more days were needed to re-rig the chains and pontoons. The boat was brought to the surface in a series of controlled lifts and she was towed back to Portsmouth, hanging from the pontoons. Four enlisted divers were awarded the Medal of Honor for their actions during the rescue and salvage phase, and one officer was awarded the Navy Cross. A truly great effort indeed.
