BASIC SUBMARINE CONSRUCTION
THE STRENGTH OF THE HULL IS INCREASED BY ADDING:
T Frames Bulkheads
Decks
Numerous holes are cut into the pressure hull for access and services,all of which weaken the pressure hull. In order to restore it to its original strength, heavier
ENVIRONMENTAL FACTORS AFFECTING
BUOYANCY
Sea water density Salinity
Temperature
Compressibility Down & Out Up & In
SUBMARINE STABILITY
The Centre of Gravity is the point through which the entire weight of the submarine may be said to act.
• SS: • SSN: • SSBN:
• FF: • DD: • DDG: • CV: • CVF:
Submarine Submarine (Nuclear Propelled) Submarine (Nuclear Propelled with Ballistic Missiles) Frigate Destroyer Destroyer with Guided Missiles Carrier Carrier with fixed wing aircraft
All heavy machinery and weights are placed at the bottom of the submarine to keep the centre of gravity as low as possible,this improves stability.
THE CENTRE OF BUOYANCY:
machinery Remain undetected - Very quiet
Work independently of air
SEA PRESSURE INCREASES AS THE SUBMARINE GOES DEEPER.
The Problem::
In PSI, pressure is approximately equal to ½ the depth in FEET.
What Happens Underwater
The Trident Missile
The Deterrent
THE SUBMARINE MUST BE ABLE TO:
Maintain watertight integrity Withstand pressure at depth
Remain manoeuvrable Provide a stable platform to carry and fire weapons Provide a habitable environment for the crew and to house

HMS VANGUARD (SSBN)
Classes of SSBN (Bomber)
• HMS Vanguard (Trident)
• HMS Victorious • HMS Vengeance • HMS Vigilant
At 100ft sea pressure is:
50 PSI
In BAR, pressure is approximately equal to 1/10 of the depth in METRES.
At 30m sea pressure is:
3 BAR
At a submarine’s Maximum Operating Depth a submarine is having to withstand pressures of 650 psi or 35 Bar
Is the point through which the entire upthrust on the submarine may be said to act
