of a vessel.
                 ML9. a. 2. d. Active weapon countermeasure systems specified by ML4.b., ML5.c. or ML11.a. and having any of the following:
1. 'CBRN protection';
2. Hull and superstructure, specially designed to reduce the radar cross section;
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. A degaussing system designed to reduce the magnetic signature of the whole vessel;
ML9. b. Engines and propulsion systems, as follows, specially designed for military use and components therefor specially designed for military use:
1. Diesel engines specially designed for submarines;
2. Electric motors specially designed for submarines and having all of the following:
a. Power output of more than 0.75 MW (1,000 hp);
b. Quick reversing;
c. Liquid cooled; and
d. Totally enclosed;
3. Diesel engines having all of the following:
a. Power output of 37.3 kW (50 hp) or more; and
b. 'Non‑magnetic' content in excess of 75% of total mass;
Technical Note:
For the purposes of ML9.b.3., 'non‑magnetic' means the relative permeability is less than 2.
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.
ML9. c. Underwater detection devices, specially designed for military use, controls therefor and components therefor specially designed for military use;
d. Anti‑submarine nets and anti‑torpedo nets, specially designed for military use;
e. Not used since 2003;
f. 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: ML9.f. includes connectors for vessels which are of the single‑conductor, multi‑conductor, coaxial or waveguide type, and hull penetrators for vessels, both of which are capable of remaining impervious to leakage from without and of retaining required characteristics at marine depths exceeding 100 m; and fibre‑optic connectors and optical hull penetrators, specially designed for "laser" beam transmission, regardless of depth. ML9.f. does not apply to ordinary propulsive shaft and hydrodynamic control‑rod hull penetrators.
ML9. g. Silent bearings having any of the following, components therefor and equipment containing those bearings, specially designed for military use:
1. Gas or magnetic suspension;
2. Active signature controls; or
3. Vibration suppression controls;
ML9. h. Nuclear power generating equipment or propulsion equipment, specially  designed for vessels specified in ML9.a. and components therefor specially               designed or 'modified' for military use.
Technical Note:
         For the purpose of ML9.h., 'modified' means any structural, electrical, mechanical, or other
