Section 6 Fragmentation and small arms

6.1.1 The submarine structure, systems and equipment are to be designed to withstand the effects of a defined fragmentation and small arms threat. Measures are to be taken to reduce the risk of injury to embarked persons.

6.1.2 As a minimum, the fragmentation and small arms protection policy will provide sufficient protection to essential structure, systems and personnel in the event of a defined threat, which shall:

1. Ensure that exposed systems, equipment and components providing submarine functions are protected and remain effective;
2. Ensure that structure preserving watertight integrity remains effective;
3. Ensure that fittings and closures remain effective and capable of operating in an emergency situation; and
4. Ensure that embarked persons are not at an increased risk of injury.

6.2.1 A fragmentation and small arms operating concept shall be developed to define the magnitude and nature of the threat. It shall identify the compartments, systems and equipment to be protected.

6.2.2 Structures protecting external, above water, compartments containing essential systems, munitions or personnel shall be capable of withstanding the defined threat.

6.2.3 Failure of a fitting or closure due to a defined threat shall not present an increased danger to essential systems or personnel on board either by its inability to operate or its failure.

6.2.4 Where required, the structure providing protection to embarked persons shall be capable of withstanding the defined threat.
