SMX-25, a French design concept for a submarine that travels at high speed on the surface to arrive in theater. Before the advent of nuclear power, submarines were slower on the surface than surface ships and even slower underwater. [14] Therefore, efforts were made to increase submarine surface speeds to that of surface-only ships. Examples:
Nereus was a hybrid uncrewed autonomous underwater vehicle (HROV, a type of remotely operated underwater vehicle) built by the Woods Hole Oceanographic Institution (WHOI). ). Constructed as a research vehicle to operate at depths of up to 11,000 metres (36,000 ft), it was designed to explore Challenger Deep, the deepest surveyed point in the global oc
The Orca dates back to September 2017, when the Navy issued contracts worth about US$40 million each to Boeing, which had partnered earlier in the year with HII to build uncrewed submarines, and Lockheed Martin to develop competing designs for an extra-large unmanned undersea vehicle (XLUUV [a]) capable of autonomous operation on missions up to ...
The Hybrid Multi-Material Rotor program is an attempt to improve the design and manufacturing process of submarine propellers with an aim of reducing the cost and weight of the propeller/rotor as well as improving overall acoustic performance.
Echo Voyager is powered by a hybrid diesel-electric system—submerged, the vehicle uses batteries for propulsion, which are recharged by a diesel-powered generator while it is surfaced. [2] The system has a power output of about 18 kilowatts (24 hp), and allows Echo Voyager to travel submerged for several days at a time at up to 9 miles per ...
A flying submarine, submersible aircraft or aerosub is a combination of a seaplane and a submarine. It is supposed to be able both to fly and to travel under water ...
The Mark 54 lightweight torpedo (formerly known as lightweight hybrid torpedo, or LHT) is a standard 12.75-inch (324 mm) anti-submarine warfare (ASW) torpedo used by the United States Navy and several other nations armed forces.
The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable. The Type 212 is the first fuel cell propulsion system equipped submarine series. [8] [9]
