Navy Divers Survey WWII Aircraft
Navy News | October 20, 2006
Jaluit Atoll, Republic of Marshall Islands - Divers and other crew members from USS Safeguard (ARS 50) assisted the Naval Historical Center (NHC) and The International Group for Historic Aircraft Recovery (TIGHAR) in a scientific survey of two submerged World War II aircraft in waters here Oct. 12.
The submerged aircraft — lost since the early days of World War II — are two U.S. Douglas Torpedo Bomber Devastators (TBDs), which played a primary role in the war’s outset. Over the four days of diving, the survey team collected data and sampled material from the TBDs for scientific analysis to evaluate their suitability for possible recovery and preservation at a later date.
Divers from Safeguard, supported by representatives from Commander, Logistics Group Western Pacific (CLWP) and Mobile Diving and Salvage Unit (MDSU) 1, assisted the Naval Historical Center through a separate but complementary engineering and salvage analysis. Additionally, Safeguard’s presence provided an additional margin of safety for both the Navy and civilian divers, since the ship carries a recompression chamber and trained diving medical technicians in the event of any diving-related injuries.
“This was a unique opportunity for Safeguard to be involved in the conservation and preservation of an important part of naval history,” said Lt. Cmdr. Doyle Hodges, Safeguard’s commanding officer. “Just the process of getting to the wreck site in the Marshalls gives you a good appreciation for the bravery of the Sailors who took these aircraft with rudimentary navigation systems across thousands of miles of open ocean. Additionally, the diving conditions in the lagoon were terrific.”
The Naval Historical Center and the National Museum of Naval Aviation have been interested for some time in assessing the condition of these two aircraft, according to officials of those organizations.
These planes were lost in the first U.S. offensive strikes of World War II, going directly after the Japanese headquarters on the Marshall Islands immediately following the bombings of Pear Harbor. They were launched from USS Yorktown (CV 5) during that initial strike, but because of the weather conditions, the pilots of the bombers could not make a path for return on the sortie, ran out of fuel, and made emergency landings in the large central lagoon near the Jaluit Atoll.
Although mostly obsolete in effectiveness during the majority of the war, TBDs served with distinction at the Battle of Midway. At Midway, the “Devastators” suffered horrendous losses, but by diverting the Japanese fighter cover, they enabled the American dive bombers to do their deadly work and contributed significantly to that critical victory, one that would turn the tide of the Pacific War.
The two TBD Devastators that sank in Jaluit have remained in the same spot since they were lost in the war; one resting on a coral ledge at only 50 feet and the other on the bottom at 130 feet. The shallower airplane was found and identified in 1997. The deeper Devastator was located in 2002.
In 2004, TIGHAR, which is a civilian nonprofit historical foundation, conducted a survey of the aircraft to explore the possibility that one could be recovered and preserved for exhibition at the National Museum of Naval Aviation.
Dr. Robert Neyland, NHC underwater archaeologist, accompanied the TIGHAR expedition as the U.S. Navy observer. Neyland recommended that Navy salvage experts also provide support in order to plan for the logistics of recovery and transport of one of the aircraft at some future date; Safeguard would end up providing that support linkage.
During the recent survey operation, the TIGHAR team, at their own expense, mapped the extent of corrosion to both wrecks and conducted analysis of water chemistry, aluminum thickness measurements and site mapping.
The combined TIGHAR and Navy research will now provide the data for preservation and potential recovery and determine if it is feasible and desirable to lift and restore one of the TBD aircraft, according to officials of the organizations.
"Safeguard divers were proud to be a part of a survey effort that shows promise of leading to a successful recovery of a TBD Devastator,” said Senior Chief Navy Diver (SW/MDV) Jeffrey Sampson, Safeguard’s master diver. “The data recovered while working with TIGHAR and the Naval Historical Society will be an integral part in future salvage and preservation operations."
Safeguard is a forward deployed rescue and salvage ship operating out of Sasebo, Japan, and is part of Task Force 76, the Navy’s only forward deployed amphibious force.
