BEST AIP Anaerobic Propulsion System (AIP)

The BEST AIP system is a third-generation Anaerobic Propulsion System designed for expeditionary submarines, providing a crucial strategic advantage for long-duration missions in hostile environments. This state-of-the-art technology enables conventional submarines to remain submerged for weeks under all defined operational conditions, from tropical to subarctic environments and across the entire depth range. This energy generation system is based on proton exchange membrane (PEM) fuel cells and bioethanol reforming, which is stored onboard in structural tanks. The advantages of the AIP system are numerous and significant. Increased submerged autonomy results in an expanded patrol area with a zero Indiscretion Coefficient, as well as an exponential reduction in the probability of being detected. Additionally, onboard hydrogen production on demand from bioethanol provides logistical, safety, and sustainability benefits. The BEST AIP system also has a positive impact on the submarine's service life, as it eliminates the need to replace equipment every 9,000 hours or during overhaul periods (every six years). This ensures the submarine can operate efficiently and sustainably over long periods without frequent maintenance interruptions.

The BEST AIP system is a unique and revolutionary solution that sets a new standard in submarine technology. It offers logistical, operational, and lifecycle benefits while improving the sustainability and efficiency of naval operations. This makes it the best option for oceanic submarines, offering unmatched performance and reliability.
