Division Vessels of war (surface or underwater), special naval equipment, accessories, components and other surface vessels, as follows:

Vessels and components, as follows:

1. 1..

   Vessels (surface or underwater) specially designed or modified for military use, regardless of current state of repair or operating condition, and whether or not they contain weapon delivery systems or armour, and hulls or parts of hulls for such vessels, and components therefor specially designed for military use;

2. 2..

   Surface vessels, other than those specified in ML9.a.1., having any of the following, fixed or integrated into the vessel:

   1. a..

      Automatic weapons - specified in ML1., or weapons specified in ML2., ML4., ML12. or ML19., or 'mountings' or hard points for weapons having a calibre of 12,7 mm or greater;

      Technical Note

      'Mountings' refers to weapon mounts or structural strengthening for the purpose of installing weapons.

   2. b..

      Fire control systems specified in ML5.;

   3. c..

      Having all of the following:

      1. 1..

         'Chemical, Biological, Radiological and Nuclear (CBRN) protection'; and

      2. 2..

         'Pre-wet or wash down system' designed for decontamination purposes; or

      Technical Notes

      1.

      'CBRN protection' is a self contained interior space containing features such as over-pressurization, isolation of ventilation systems, limited ventilation openings with CBRN filters and limited personnel access points incorporating air-locks.

      2.

      'Pre-wet or wash down system' is a seawater spray system capable of simultaneously wetting the exterior superstructure and decks of a vessel.

   4. d..

      Active weapon countermeasure systems specified in ML4.b., ML5.c. or ML11.a. and having any of the following:

      1. 1..

         'CBRN protection';

      2. 2..

         Hull and superstructure, specially designed to reduce the radar cross section;

      3. 3..

         Thermal signature reduction devices, (e.g., an exhaust gas cooling system), excluding those specially designed to increase overall power plant efficiency or to reduce the environmental impact; or

      4. 4..

         A degaussing system designed to reduce the magnetic signature of the whole vessel;

Engines and propulsion systems, as follows, specially designed for military use and components therefor specially designed for military use:

1. 1..

   Diesel engines specially designed for submarines and having all of the following:

   1. a..

      Power output of 1,12 MW (1 500 hp) or more; and

   2. b..

      Rotary speed of 700 rpm or more;

2. 2..

   Electric motors specially designed for submarines and having all of the following:

   1. a..

      Power output of more than 0,75 MW (1 000 hp);

   2. b..

      Quick reversing;

   3. c..

      Liquid cooled; and

   4. d..

      Totally enclosed;

3. 3..

   Non-magnetic diesel engines having all of the following:

   1. a..

      Power output of 37,3 kW (50 hp) or more; and

   2. b..

      Non-magnetic content in excess of 75 % of total mass;

4. 4..

   'Air Independent Propulsion' (AIP) systems specially designed for submarines;

   Technical Note

   'Air Independent Propulsion' (AIP) allows a submerged submarine to operate its propulsion system, without access to atmospheric oxygen, for a longer time than the batteries would have otherwise allowed. For the purposes of ML9.b.4., AIP does not include nuclear power.

Underwater detection devices, specially designed for military use, controls therefor and components therefor specially designed for military use;

Anti-submarine nets and anti-torpedo nets, specially designed for military use;

Not used since 2003;

Hull penetrators and connectors, specially designed for military use, that enable interaction with equipment external to a vessel, and components therefor specially designed for military use;

Note

Silent bearings having any of the following, components therefor and equipment containing those bearings, specially designed for military use:

1. 1..

   Gas or magnetic suspension;

2. 2..

   Active signature controls; or

3. 3..

   Vibration suppression controls.
