Salvage of Indonesian Submarine Ends but Questions Loom

Indonesia ended salvage efforts on Wednesday to retrieve a disaster-stricken submarine that cost 53 lives and prompted questions over the maintenance of military equipment in the world's fourth most populous nation.The 44-year-old submarine lost contact with the Indonesian navy on April 21 while preparing for a torpedo drill in the Bali Sea, triggering a desperate international search and rescue effort to find it before oxygen supplies ran out.When the vessel was discovered days later in three parts, authorities acknowledged the difficulties of recovering the submarine from a depth of 840 meters (2

of the DIVE-LD has proven to be an excellent platform for the MINSAS 120 payload, and the open architecture and free flooded design allowed for simple and flexible payload mounting options.”Kraken and Dive Technologies entered into an agreement in August 2020 whereby Kraken agreed to supply subsea batteries for the DIVE-LD. Under the terms of the agreement, Kraken also acquired a license to build two DIVE-LDs for use in Kraken’s growing Robotics-as-a-Service (RaaS) business. Production of Kraken’s first DIVE-LD is currently underway with the first unit being manufactured in the

Divers Find Deepest Known Shipwreck USS Johnston

A privately funded mission has found, surveyed and filmed the USS Johnston, the world’s deepest known shipwreck, offshore Samar Island in the Philippines Sea.The expedition was backed by Victor Vescovo, is an entrepreneur, explorer and retired U.S. Navy Commander who personally piloted his submersible DSV Limiting Factor down to the wreck during two separate, eight-hour dives 21,180 feet (6,456 meters) below the ocean's surface. These constituted the deepest wreck dives, manned or unmanned, in history."The image is impressive and we look forward to seeing the rest of the data

European Countries Helping Taiwan with Submarine Project

European countries are providing help for Taiwan’s indigenous submarine project, the island’s defense ministry said, in a rare admission that the sensitive program is not getting assistance solely from the United States.Taiwan, which China claims as its own territory, has worked for years to revamp its submarine force, some of which dates back to World War Two. It is no match for China’s fleet, which includes vessels capable of launching nuclear weapons.The U.S. government in 2018 gave the green light for U.S. manufacturers to participate in the program, a move widely seen as helping

US Navy Recovers Downed Helicopter from Record Ocean Depth

The U.S. Navy last week retrieved one of its crashed helicopters from 19,075 feet below the surface of the North Pacific, setting a record for the deepest aircraft recovery at sea.The helicopter, a twin engine Sikorsky Seahawk, crashed off the coast of Okinawa, Japan last year while operating from the amphibious command ship USS Blue Ridge (LCC-19). The air crew was able to escape the MH-60S before it sank and no lives were lost in the accident.Responding to a U.S. Pacific Command Fleet request, the Naval Sea Systems Command’s (NAVSEA) Supervisor of Salvage and Diving (SUPSALV) located and
