At
IDEX-2013, China revealed a scaled-down version of Type 039A submarine designated as S20, specially intended for export. The main difference between S20 and Type 039A is that the AIP system on the original Type 039A is deleted, but can be available and easily integrated due to modular design of S20, if potential customers choose to purchase AIP systems separately. Due to its modular design, a variety of sensors and weapons can also be easily adopted up on customers' requests.
[9] Specifications of S20:

The
Agosta-class submarine is a
class of
diesel-electric fast-attack submarine developed and constructed by the
French DCNS in 1970s to succeed the
Daphné-class submarines. The submarines have served in the
French Navy as well as exported to the navies of
Spain and
Pakistan. It also used by
Royal Malaysian Navy for the training purpose. They were replaced in French service by the
Rubis-class nuclear attack submarines but are still in
active service with the navies of
Spain and
Pakistan. The French Navy grouped this model of submarine in their most capable class as an
océanique, meaning "ocean-going."

The
Scorpène-class submarines are a class of
diesel-electric attack submarines jointly developed by the
French Direction des Constructions Navales (DCNS) and the
Spanish company
Navantia, and now by
Naval Group. It features diesel propulsion and an additional
air-independent propulsion (AIP). It is now marketed as the Scorpène 2000.

Scorpène characteristics[edit]
The Scorpène class of submarines has four subtypes:
[3] the CM-2000 conventional diesel-electric version, the AM-2000
air-independent propulsion (AIP) derivative, the downsized CA-2000 coastal submarine, and the enlarged S-BR for the
Brazilian Navy, without AIP.
[4]
The Chilean and Malaysian boats are fitted with the TSM 2233
Mk 2 sonar. The class can also be fitted with an 'S-Cube' sonar suite from
Thales.
[5]
Air-independent propulsion[edit]
The French Module d'Energie Sous-Marine Autonome (MESMA) system is being offered by the French shipyard
Direction des Constructions Navales (DCNS) for the Scorpène-class submarines. It is essentially a modified version of their nuclear propulsion system with heat being generated by
ethanol and oxygen. The combustion of the ethanol and stored oxygen, at a pressure of 60 atm (6.1 MPa), generates steam which powers a conventional turbine power plant. This pressure-firing allows exhaust carbon dioxide to be expelled overboard at any depth without an exhaust compressor.
Each MESMA system costs around US$50–60 million. As installed on the Scorpènes, it requires adding a new 8.3-metre (27 ft), 305-tonne hull section to the submarines, and enables a submarine to operate for more than 21 days under water, depending on variables such as speed.[

DCNS is also developing second-generation hydrogen fuel cell AIP modules for future Scorpène models.
