air-independent propulsion

The 212 features an air-independent propulsion system using hydrogen fuel cells.

They can be built to run quietly and without an air supply, for air-independent propulsion use in submarines.

The installation of an air-independent propulsion system might be considered in a future refit or upgrade program.

The submarines will feature air-independent propulsion and are expected to start joining the navy during the second half of 2015.

One project that was abandoned was the development of a fuel cell based air-independent propulsion system.

It is also unclear if the incorporation of air-independent propulsion system has become the standard or just for evaluation purposes.

Today several navies use air-independent propulsion.

The introduction of air-independent propulsion boats led to increased sales numbers of such types of submarines.

Today several navies, notably Sweden now use air-independent propulsion boats, which substitute liquid oxygen for hydrogen peroxide.

It features diesel propulsion and an additional air-independent propulsion (AIP).

Equipped with air-independent propulsion, or even with nuclear power, and armed with atomic torpedoes, they posed a deadly threat.

Ltd.) in the design and construction of six submarines equipped with air-independent propulsion (AIP).

The Asashio, has been modified to test Air-independent propulsion (AIP).

It is also possible to upgrade these submarines with the latest Air-independent propulsion (AIP) systems.

The only earlier attempt to use a chemical reaction based air-independent propulsion system was in the Spanish submarine the Ictineo II.

Their main use, however, was to finally prove that HTP was impractical as an air-independent propulsion for submarine use.

The most important innovation in the Ictineo II was its anaerobic engine (Air-independent propulsion) for underwater navigation.

These two new boats are similar to the highly advanced German U212 submarine and feature an air-independent propulsion (AIP) system.

The latter two have undergone comprehensive refits, including the insertion of a new hull section with an Air-independent propulsion system equipped with Stirling engines.

The German Type 212 submarine uses nine 34-kilowatt hydrogen fuel cell as air-independent propulsion, which makes it first series production submarine using fuel cell.

The two new boats are an upgraded version of the older Dolphins, featuring an air-independent propulsion system, similar to the one used on German Type 212 submarines.

India signed a deal for six Scorpène class submarines with MESMA air-independent propulsion and construction has begun.

Equipped with the MESMA air-independent propulsion system, a Scorpene can remain submerged for periods in excess of 3 weeks.

It was the catalyst for a series of German-made Air-independent propulsion submarines such as the Type 212 submarine and Type 214 submarine.

Monopropellants are also used in some air-independent propulsion systems (AIP) to "fuel" reciprocating or turbine engines in environments where free oxygen is unavailable.
