Phoenix and SUPSALV perform record breaking salvage

5th April 2021

Phoenix International, USA, under the direction of the US Navy’s Supervisor of Salvage and Diving (SUPSALV), has located and recovered the fuselage of a downed MH-60S Seahawk helicopter in the Pacific, near Okinawa, Japan, from a record breaking depth of 19,075 feet (5814 metres).


This equates to just over 3.6 miles (5.8 kilometres) beneath the sea and is 266 feet (81 metres) deeper than the previous salvage record, also set by Phoenix and SUPSALV during an operation in 2019.


The helicopter was located in March of 2020 using the US Navy’s autonomous underwater vehicle Trondheim and then, a year later, Phoenix and SUPSALV returned to the site and recovered the helicopter using the US Navy’s remotely operated vehicle CURV 21 and Fly Away Deep Ocean Salvage System.


Both Trondheim and CURV 21 are rated to operate down to 20,000 feet (6000 metres).
