    In the past two decades, propulsors have taken the place of traditional propellers on some advanced submarines, including the US Navy’s Seawolf and Virginia class nuclear fast attack boats, which has been a particularly interesting evolution.

    What is air independent propulsion in a submarine?
    Air-independent propulsion. Air-independent propulsion (AIP) is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.

    What type of propulsor does a Virginia class submarine use?
    Propulsor In contrast to a traditional bladed propeller, the Virginia class uses pump-jet propulsors (built by BAE Systems), originally developed for the Royal Navy 's Swiftsure -class submarines. The propulsor significantly reduces the risks of cavitation, and allows quieter operation.

    Could the US Navy build a next-generation attack submarine?
    Although the U.S. Navy is busy building the more conventional Virginia -class submarines, it might fold features from Sub 2000 into a next-generation attack submarine. Talk to us at our new home at Reddit.

    What do we know about the US Navy's new double-hulled submarines?
    US Navy submarines haven't had true double hulls since the 1950s, so this is a break from the norms.” The pumpjet propulsion system is encased within the hull instead of sitting in a bulb-shaped basket at the stern. “The most sensitive feature is likely to be the completely encased pumpjet propulsion,” Sutton said.
