  2. Air-independent propulsion - Wikipedia

    en.wikipedia.org/wiki/Air-independent_propulsion

    The first submarine in the class, Sōryū, was launched on 5 December 2007 and delivered to the navy in March 2009. The eleventh of the class is the first one that is equipped with lithium-ion batteries without a Stirling engine. [16] This submarine may have a range from AIP of 6500 nautical miles and can remain submerged for 40 days. [6]

  3. Greater Underwater Propulsion Power Program - Wikipedia

    That analysis led [1] to four goals—increasing the submarines' battery capacity, streamlining the boats' structures, adding snorkels, and improving fire control systems. The navy immediately focused on designing a new class of submarine, but the Bureau of Ships believed the fleet of existing Gato , Balao , and Tench -class submarines could be ...

    en.wikipedia.org/wiki/SSN(X)-class_submarine

    The SSN(X) or Next-Generation Attack Submarine program of the United States Navy aims to develop a new class of nuclear-powered attack submarines to succeed the Virginia and Seawolf classes. The SSN(X) program remains in the early stages of development and no official details have been released about its design or capabilities.

  5. Gotland-class submarine - Wikipedia

    en.wikipedia.org/wiki/Gotland-class_submarine

    The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. [2]

  6. Underwater thruster - Wikipedia

    en.wikipedia.org/wiki/Underwater_thruster

    Electric thrusters are mainly used on battery operated underwater robots such as AUVs, submarines, and electric ROVs. Electric thrusters usually use brushless DC or permanent magnet synchronous motors (PMSM). These motors may be sealed within air- or oil-filled cavities, or use a flooded design that allows water to come into contact with the ...

    PNS/M Saad (S-138) is a diesel-electric fast-attack submarine equipped with an air–independent propulsion system and the second of the Agosta-90B/Khalid-class submarines jointly designed and constructed by France and Pakistan.

  9. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    The film adaptation of The Hunt for Red October popularized the magnetohydrodynamic drive as a "caterpillar drive" for submarines, a nearly undetectable "silent drive" intended to achieve stealth in submarine warfare. In reality, the current traveling through the water would create gases and noise, and the magnetic fields would induce a ...
