Are the AUKUS submarines worth the $368 billion price tag?
Are nuclear powered submarines really the ‘cutting edge’ technology we are led to believe in an effort to justify the $368 billion cost to Australian taxpayers? the latest submarines still base their propulsion systems on steam – which clearly is well proven old technology. In the new British dreadnought class subs the reactor drives two GEC steam turbines linked to a single shaft pump jet propulsor, giving the submarines a maximum submerged speed of over 25 knots (46km/h. Auxiliary power is provided by a pair of 6MW steam-turbine generators.
