Air-independent propulsion

The French MESMA (Module d'Energie Sous-Marine Autonome) system is being offered by the French shipyard DCN for the Scorpène class submarines. It is essentially a modified version of their nuclear propulsion system with heat being generated by ethanol and oxygen. A conventional steam turbine power plant powered by steam generated from the combustion of ethanol (grain alcohol) and stored oxygen at a pressure of 60 atmospheres. This pressure-firing allows exhaust carbon dioxide to be expelled overboard at any depth without an exhaust compressor.

Each MESMA system costs around $50–60 million. As installed on the Scorpène, it requires adding a new 8.3 meter (27 foot), 305 tonne hull section to the submarine, and results in a submarine able to operate for greater than 21 days underwater, depending on variables like speed.

Orders

In 2003 the Spanish government ordered 4 Scorpène-AIP submarines worth €1,756 million. Implying a cost of 439 million Euros each. However the order of 4 Scorpène submarines for the Spanish navy was canceled and four S-80 class

 submarines have been ordered instead. This has caused conflicts and controversies between DCNS and Navantia as the latter is still involved in the construction of the submarines sold to India, Malaysia and Chile while the S-80 is offered on the export market. As an answer to the concurrence from the S-80, DCNS designed its own enhanced version of the Scorpène called the Marlin class

 but little is known about this design and the Scorpène is still offered by France on the export market.

In 2005, India chose the Scorpène' design; purchasing six for US$ 3 billion (US$500m per boat). These submarines are to be manufactured under a technology transfer agreement by the state-owned Mazgoan Docks in Mumbai and delivered between 2010 and 2015. Construction started on 23 May 2007.

In 2009 Brazil purchased 4 enlarged Scorpène for US$ 9,9 billion with a big technology transfer agreement and a second agreement to develop a French/Brazilian nuclear powered submarine. The hull of the first S-BR (S35) was laid down at Cherbourg on 27 May 2010 and is to be jumboïzed at Brazilian Navy Shipyard in Sepetiba

 late 2012. The latter 3 submarines will be entirely built there and are planned to be commissioned in 2018, 2020 and 2021. The nuclear powered submarine could be a variant of the Scorpène class (which would make it similar in concept to the ) or a more powerful Barracuda class one.
