the buoyant force (upthrust) exerted on the submarine by the surrounding water
the tension force in the steel cables supporting its external instrument pack
the gravitational force of attraction exerted by the submarine on the Earth
the downward force of the hydrostatic water pressure on the upper deck of the submarine
