Aircraft carrier buoyant support force
Aircraft carrier buoyant support force is the upward force from water that counteracts the weight of an aircraft carrier, enabling it to float.
Also known as: aircraft carrier buoyancy

A little perspective
Aircraft carrier buoyant support force vs Suspension bridge main-cable tension: weight comparison
The buoyant support force on an aircraft carrier is about 5 times the main-cable tension of a suspension bridge.
FORCE
Aircraft carrier buoyant support force is the upward force from water that counteracts the weight of an aircraft carrier, enabling it to float.
Suspension bridge main-cable tension is the pulling force transmitted along a main cable to support the structure and its loads.
Measurements, assumptions & sources +
Aircraft carrier buoyant support force
Defined buoyant support force: 1,000 MN; derived calculation; range 800 MN–1,200 MN.
A defined 1.0 GN buoyant force balancing the weight of an approximately 102,000 tonne displaced mass at rest. Loading, seawater density and motion change displacement and support forces.
Defined examples — our methodology
The marked defined buoyant support force is calibrated. Unmeasured illustration details are representative.
Suspension bridge main-cable tension
Defined main-cable tension: 200 MN; defined engineering model; range 100 MN–500 MN.
A defined 200 MN tension in one main cable of a very large suspension bridge. Actual tension varies along the cable and with span geometry, dead load, traffic, wind and temperature.
Defined examples — our methodology
The marked defined main-cable tension is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 1,000 MN
We compare the buoyant support force on an aircraft carrier. This is calculated from stated inputs and assumptions, not a direct measurement. The recorded range is 800 MN to 1,200 MN.
A defined 1.0 GN buoyant force balancing the weight of an approximately 102,000 tonne displaced mass at rest. Loading, seawater density and motion change displacement and support forces.
