1. no so called 'Typ041' ...

2. the Thailand Navy S-26T is based on this Type039A(not the latest PLAN varient 039B )...around 2600 tons (surface)

3. the Pakistan Navy chose the S-20 (scale down varient)...obviously the displacement is around 2000tons (surface)

--------
Type039A/S26T


-------
S26 vs S20


--------
and the PLAN's 039B

1.stirling engine AIP.
2.no VLS,it's a just a 3000 tons(underwater) vessel..tube launched ASM

----------------
PLAN‘s 039B which is under massive construction at this stage. the 035G is almost gone, the next type leaving is the 035B.

Sterling Cycle Engines

A Sterling Engine is a closed cycle engine with a working fluid which is permanently containedin the system. A source of energy is used to heat this working fluid, which in turn moves the pistons and runs the engine. The engine is coupled to a generator, which generates electricity and charges the battery. The source of energy used here is typically LOX as oxidizer and diesel fuel, which is burnt in order to generate heat for the working fluid. The exhaust is then scrubbed and released into the seawater.

The advantage of using Sterling engines is the easy availability of diesel fuel and low refueling costs when compared with Fuel Cells. They are also quieter than MESMA and hence preferred by the Japanese for their Soryu class, Sweden for their Gotland and Västergötland class and China for their Yuan class.

The main drawback is that they are relatively noisy when compared to Fuel Cells due to the presence of a large number of moving parts. They are also bulky when compared to Fuel Cells. The operating depth of a submarine using Sterling AIP is limited to 200 m when AIP is engaged.

China to Supply Pakistan With 8 New Stealth Attack Submarines by 2028
China will provide the Pakistan Navy with eight modified diesel-electric attack submarines by 2028, the head of the country’s next-generation submarine program told the Pakistan National Assembly’s Standing Committee on Defense during the committee’s visit to the Naval Headquarters in Islamabad on August 26, according to local media reports.

The Pakistani senior naval official’s statement in front of the committee members provides official confirmation that the program is moving ahead, although it is still unclear whether a contract has been signed. In April, a senior Pakistan Navy official announced that Karachi Shipyard & Engineering Works (KSEW) had secured a contract to produce four of the eight submarines, which will be fitted with air-independent propulsion (AIP) systems.

The defense deal is valued at $4 to $5 billion and China is expected to extend a long term loan at a low interest rate. It has not officially been confirmed what type of submarine will be supplied to the Pakistan Navy by the China Shipbuilding Trading Company (CSTC) and there has been considerable speculation on the subject in the past (See: “Confirmed: Pakistan Will Buy Eight Chinese Subs”):

[T]he Wuhan-based China State Shipbuilding Industrial Corp (CSIC) supposedly had already signed a contract in April 2011 to deliver six Type 032 Qing-class conventional attack submarines by 2016/2017. (…) [O]ther media sources report that Islamabad will build submarines under license based on the Qing-class vessels displacing 3,000 tons: “Pakistan will also build two types of submarines with Chinese assistance: the Project S-26 and Project S-30. The vessels are to be built at the Submarine Rebuild Complex (SRC) facility being developed at Ormara, west of Karachi.”
The majority of analysts speculate that the new submarine will be a lighter export version of the People Liberation Army Navy (PLAN)’s Type 039 and Type 041 Yuan-class conventional attack submarine, excluding the sub’s AIP system, which might be procured independently.

According to IHS Jane’s Fighting Ships, the Type 041 Yuan-class is “a diesel electric attack submarine (SSK), potentially with Stirling air-independent propulsion, that is armed with YJ-2 (YJ-82) anti-ship missiles and a combination of Yu-4 (SAET-50) passive homing and Yu-3 (SET-65E) active/passive homing torpedoes.”

It purportedly is one of the quietest subs in the PLAN’s inventory. The scaled-down 2,300-ton export version is designated S20. The first four submarines are expected to be delivered by the end of 2023; the remaining four will be assembled in Karachi by 2028. The new subs are expected to form the the sea-based arm of Pakistan’s burgeoning nuclear second-strike triad.

The Pakistan Navy is in middle of upgrading its undersea warfare capabilities. In June, Turkish state-owned defense contractor STM won a contract for the mid-life upgrade of three Agosta 90B-class (aka Khalid-class) diesel-electric attack submarines equipped with air-independent propulsion systems.

Pakistan’s New Type-039B AIP Submarines: Image Shows Shipyard Expansion

The eight Type-039B ‘Hangor Class’ submarines will be a major boost to the Pakistan Navy. They will more than double the size of the Pakistan Navy’s submarine fleet. The new submarines are variant of the Chinese Navy’s Type-039A Yuan Class. Construction will be split between the China Shipbuilding Industry Corporation (CSIC) and Karachi Shipyard & Engineering Works (KSEW) in Karachi. KSEW previously participated in local construction of Pakistan’s French designed Agosta class submarines. The construction site in Karachi may put to rest previous reports that the subs would be built in Ormara. In 2016 it was reported that the local submarine construction would occur at a new Submarine Rebuild Complex (SRC) being built there. No significant construction work is evident at Ormara. The new construction hall and dry dock are at the southern end of KSEW’s Karachi shipyard site. Footings for the halls was first observed in 2015. The twin-lane halls have slowly taken shape since then. The outer shell appears largely complete. Under their roof there should be enough room to build two submarines in parallel. Work on the aligned dry dock appears to have started in 2016. It is a Norwegian designed Syncrolift ship-lift type built out over the water. Manufacture of the sections likely took place in China. The dry dock is 126m (415 ft) long and 32m (105 ft) across and has a lifting capacity of 7,881 tons. This is large enough for the new submarines, and would allow frigate sized warships and larger submarines in future. Based on current information the first of the new submarines, built in China, is expected to be delivered in 2022. Local construction of the last four hulls will last through to 2028. The acquisition from China is part of a trend. Several major Pakistan Navy warship programs have gone to China in recent years. And the Pakistan Navy and Chinese Navy already cooperate closely, included close exercises involving Chinese warships and Pakistan Navy submarines. The construction halls will be conveniently close to the Pakistan Navy’s main submarine berths. They are also just north of the SSGNs (Special Service Group (Navy)) base at PNS Iqbal. This is where the Pakistan Navy’s X-Craft midget submarine program is based. It seems logical that any local construction of midget submarines will also take place at the new site. The technology transfer will benefit KSEW. Their Stirling-based AIP (Air Independent Power/Propulsion) technology is different from the French MESMA system installed on Pakistan’s Agosta-90B type boats. Pakistan remains the only country to adopt the MESMA system. Type-039B submarines are a relatively conservative design however. The Type-039B submarines are likely to combine Chinese systems and weapons with Pakistani systems. Local weapons are expected to include the nuclear-capable Babur cruise missile. Armed with these the boats will form part of Pakistan’s nuclear deterrent. How this deterrence role will be reconciled with typical attack submarine duties remains unclear.

Pakistan’s New Type-039B AIP Submarines: Image Shows Shipyard Expansion
The Pakistan Navy's expansion is gearing up in Karachi. Major enhancements are evident at a shipyard, where a new construction hall and a dry dock greatly increase capacity. Although details are scarce, it seems likely that the local construction of Chinese-designed AIP (Air Independent Power) submarines will take place there.
