Q

Embarking and disembarking and storing the weapons?

Where are they stowed ?
Where do you get the procedures ?
What’s needed ?

A

.A safe and rigid procedure is required to enable the sub to embark and disembark and store the weapons.

.procedures for these requirements are in tactical weapons operating procedures in submarines (TWOPS)

.weapons are stored in the WSC.

. When fully laden, the WSC is a very restrictive compartment to be in.

Q

What can happen is oxygen is low on board. And how is it rectified ?

A

Crew become lethargic and drowsy.

Simple tasks become difficult to carry out.

This is rectified by increasing the output of the electrolyser.

Q

If the oxygen level is too high.

A

The crew become hyperactive and are unable to sleep.

This is rectified by reducing the oxygen output and allowing the level to fall naturally.
