  1. The Emergency Propulsion System provides the submarine with an alternative means of propulsion and manouvering Operating independently of the primary propeller shaft, the emergancy propulsion system, or secondary propulsion system, provides a 'get me home' capability with an independant propulsor deployed when needed.

    Why choose global for submarine propulsion systems?
    Global Our market-leading position in submarine propulsion systems encompasses everything from design and procurement to manufacture and in-service support. For the last 60 years we have designed, supplied and supported the nuclear propulsion plant that provides power for all of the UK Royal Navy's nuclear submarines.

    What is a pump jet submarine?
    In the photo, above, the Russian Navy B-871 Alrosa is the only Kilo-class sub that uses a pump jet propulsion system instead of a conventional propeller. The US Navy has reached the limits of noise reduction with mechanical system propulsion. The current Virginia Class submarines use a propulsor or ‘pump jet’ instead of a traditional screw design.

    What is a ship’s propulsion system?
    A ship’s propulsion system is probably the most important system on a ship, however, this does not negate the purpose of various other systems that support the propulsion system in its operation. A ship will not be able to move without a Propulsion Unit, also known as a Prime Mover, or Propulsion Engine, as part of its propulsion system.

    What is a secondary propulsion motor (SPM)?
    It's the propulsion system of last resort. The Secondary Propulsion Motor (SPM) is a large electric motor that is directly connected to the shaft and can turn it to propel the ship at about 8 knots. The diesel is used run a generator to create electricity to charge the batteries and run the ship, including either the SPM or EPM.
