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

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

Indian Navy's New Submarine Commissioned

The Indian Navy has commissioned its third Kalvari-class submarine, INS Karanj, built entirely in India to Naval Group's Scorpene design.The Scorpene is a 2,000-ton conventional-propulsion submarine designed and developed by Naval Group for all types of mission, such as surface vessel warfare, anti-submarine warfare, long-range strikes, special operations or intelligence gathering. Extremely stealthy and fast, it has a level of operating automation that allows a limited number of crew, which reduces its operating costs significantly. Its combat edge is highlighted by the fact that it has six
