China’s First AIP Submarine Unit Breaks Records
China’s first submarine unit using air-independent propulsion (AIP) technology recently broke a number of records set by the Chinese navy, Science and Technology Daily recently reported.

The Type 039A submarine (NATO reporting name: Yuan-class) is the People's Liberation Army Navy (PLAN)'s first AIP powered submarine.

Records such as the longest sailing distance, maximum submergence depth and sinking target ships under boundary conditions were all broken by the unit.

Military commentator Zhang Haixiong disclosed that submarines equipped with AIP technology prolong operation duration underwater to about two or three weeks, indicating the increasing stealth of the submarines.

The time a conventionally powered submarine can spend underwater ranges from 10 to 100 hours, as they need to surface regularly to charge. However, submarines can be charged underwater if they are equipped with the AIP system.

Zhang noted that AIP submarines, with higher combat effectiveness, are second only to nuclear submarines, adding that although AIP submarines are more expensive right now, in the future they will become the conventional option.

@Zarvan This might be a testbed for Pak Version, Wht do u think?

It could be let see but I think our Submarines will be totally new design. If these would have been our subs than we would have gotten at least 4 by 2021

If it would be new design , than it would be a new model, but all we know about Pak Subs,is that they are Yuan Class, and i doubt that it will include major design changes.

How does Chinese AIP performs vs its competitors?

How does Chinese AIP performs vs its competitors?

Current AIP systems

Stirling Engines The original Stirling Engine was patented in 1816 by British engineer Robert Stirling as a rival to the Steam engine. Although successful it was largely replaced by the electric motor in the early 1900s and almost forgotten, until the Swedes looked for clever ways to propel a submarine. The engine’s heat is produced in a combustion chamber but it is separated from the actual engine. The heat is transferred to the engine's working gas (e.g. oxygen), operating in a completely closed system. The working gas forces the pistons in the engine to move, thus producing mechanical energy.
Pros: Stirling engines are well tested and simple
Cons: They are relatively bulky, comparatively noisy due to moving parts. Limits the submarine’s operating depth to about 200m when in use.

Fuel Cells mix oxygen with a hydrogen-rich chemical to produce an electric current. Fuel cells use an electrochemical reaction in which oxygen and a hydrogen-rich fuel combine to form water, and electricity. Unlike internal combustion engines, the fuel is not combusted. Instead the energy is released electrocatalytically. Fuel Cell AIP was developed in the 1980s for the German Navy. The main system in use today is the German designed Seimens PEM (Polymer Electrolyte Module), but Indian and American firms also supply them for AIP submarines.
Pros: Fuel Cells have a high power density and generally provide the longest endurance of current AIP systems. They are very quiet and the technology is seen as offering further potential
Cons: They are expensive and complex.

SINAVY PEM fuel Cell AIP.

MESMA (Module d'Energie Sous-Marine Autonome) is a French system which runs a steam turbine off the chemical reaction between ethanol and oxygen. In many respects the system is based on the nuclear propulsion but with an alternative heat source. Only Pakistan fields this type of AIP currently.
Pros: MESMA has a high power output potentially allowing greatest underwater speed
Cons: They are relatively thirsty, noisy and have complex plumbing.

If our Submarines would have been same or even similar to Type 39 or what ever China currently have than we would have gotten first submarine by now. But I am pretty sure it's totally new design

all world respected sites like jane's,and others stated that it is a version of Type-39B yuan class submarines called S-26 @Zarvan

They are all making guesses we never declared the Type neither did Chinese

AIP always have a longer range and almost 4 time underwater endurance.

they were just guessing and not verified from both parties (china and Pakistan) LOL what a logic you have @Zarvan

And I am telling you that we haven't declared any type. And sorry for many defense related websites their source is this website. I have been following these websites on daily bases for past 10 years. And sorry many of these websites are taking things from various defense forums

Keep dreaming and lives in fantasy world of yours or you may ask so called insider in PN @Zarvan , its version of Tpe-39B and that all @Zarvan

It Most probably will be a Yuan Class but bit more modified for Pakistan,

Pakistan has always gone with mature platforms as it saves money and time, Pakistan cant go fro a Test Bed Platform as they are already lagging behind Indian Navy.
and if it was a newer platform delivery wouldnt start in 2023 than it would have taken much more time
