2 more MESMA AIP by 2011!

[Penguin]

well do any american submarine have AIP system all european submarines has this system this is calles air independent air fuel which make sub to dive for longer periods of time

US subs are all nuclear powered and therefor by definition have propulsion that is air independent. The AIP systems in the form of a Sterling engine or special (PEM) fuelcells are specifically designed to be added to conventional (non-nuclear) submarines, to give extend their submerged enduracne and give them similar advantage that the nuclear powered subs have.

See: Air-independent propulsion - Wikipedia, the free encyclopedia

As of 2009, some nations have non-nuclear AIP submarines:

the French-Spanish Scorpène-class submarine (1,700 tonnes) (MESMA)
the Spanish S-80 class (2,400 tonnes) of the Spanish Navy
the German Type 209-1400mod (1,810 tonnes) (Fuel cell)
the German Type 212 submarine (1,830 tonnes) (Fuel cell) of the German Navy and Italian Navy
the German Type 214 (1,980 tonnes) (Fuel cell)
the Russian Project 677 Лада (Lada)
the Russian Project 1650 Амур (Amur)
the Japanese Asashio (2,750 tonnes) (Stirling AIP) of the Japan Maritime Self-Defense Force
the Japanese Sōryū class submarine (4,200 tonnes) (Stirling AIP) of the Japan Maritime Self-Defense Force
the Swedish Gotland class submarine (1,450 tonnes) (Stirling AIP) of the Swedish navy
the Swedish Södermanland class submarine (1,500 tonnes) (Stirling AIP) of the Swedish navy
Sweden is going to sell its remaining two Västergötland class submarines to the Republic of Singapore Navy after they have been refitted with Stirling AIP systems like the Södermanland class submarines.

the Chinese Type 041 Yuan class submarine (Stirling AIP) of the PLAN
Also several shipbuilders offer AIP upgrades for existing submarines:

German Nordseewerke (Closed-cycle diesel)
Sweden Kockums (Stirling), owned by German company ThyssenKrupp
Pakistan Agosta 90B class submarine Made with cooperation with France
French Scorpene made by French Company DCNS

Delivery should have been done in 2010 but French showing their colors and delaying a necessary piece of equipment to our Agustas what was agreed to be delivered latest by 2010. Better late than never.

What kind of technical advantage do these items offer ?

Then the traditional subs - ?

it gives extendes time limit for which the submarine can stay submerged witout the need of snorkling.

Air-independent propulsion (AIP) is a term that encompasses technologies which allow a submarine to operate without the need to surface or use a snorkel to access atmospheric oxygen. The term usually excludes the use of nuclear power, and describes augmenting or replacing the diesel-electric propulsion system of non-nuclear vessels. The United States Navy uses the hull classification symbol "SSP" to designate boats powered by AIP, while retaining "SS" for classic diesel-electric attack submarines.[1]

AIP is usually implemented as an auxiliary source. Most such systems generate electricity which in turn drives an electric motor for propulsion or recharging the boat's batteries. The submarine's electrical system is also used to provide "hotel services"—ventilation, lighting, heating etc—although this consumes a small amount of power compared to that required for propulsion.

A benefit of this approach is that it can be retrofitted into existing submarine hulls by inserting an additional hull section. AIP does not normally provide the endurance or power to replace the atmospheric dependent propulsion, but allows it to remain submerged longer than a more conventionally propelled submarine. A typical conventional power plant will provide 3 megawatts maximum, and an AIP source around 10% of that. A nuclear submarine's propulsion plant is usually much greater than 20 megawatts.

i hope this helps you recognize the need of AIP for our Agosta!

regadrs!

pak help ???? .... mesma ain't pak made....

i know what u mean...but when we will increase subs in our inventory...ur politicions will feel embarrased and try to get some for u gyz too as soon as possible...cuz if we dont get more subs ur politicions will not pay attention to ur needs so they will sleep for time being...so thats how the competition goes on...see how Pak gonna help u guyz...
