Naval Group is leading the AIP revolution in submarine technology. AIP stands for Air Independent Propulsion. This technology gives non-nuclear submarines unprecedented operational ability by enabling to stay submerged for weeks at a time.
Traditionally, non-nuclear submarines run on diesel and electricity. Underwater they use battery power. After running submerged for a few days, the batteries are drained and the submarine must surface. At which point the diesel generator recharges the batteries, while the submarine runs at snorkel depth, traveling just below the surface.
A submarine that has to surface every few days loses the element of surprise and exposes itself to detection. Enter Air Independent Propulsion, which enables diesel boats to stay submerged for weeks at a time. It is estimated that nearly all of the world’s major submarine fleets will integrate AIP technologies into their non-nuclear boats.
Naval Group has developed an AIP system powered by 2nd generation fuel cells call FC2G.
