Its Confirmed, Pakistan Navy Acquiring 8 New Type 041 Improved Yuan Class Submarines From China

Pakistan is renewing efforts to modernize its submarine arm with eight submarines from China as well as a search for surplus European submarines.

Navy and Defence Ministry officials revealed the plans to the National Assembly Standing Committee on Defence on Tuesday, with Economic Affairs Secretary Muhammad Saleem Sethi leaving for China to pursue the deal on Wednesday.

Analysts believe that since the National Security Committee has agreed to the deal in principle, it is likely to go ahead.

The officials also requested US $294 million to upgrade ATR-72 maritime patrol aircraft. Two un-upgraded aircraft are in service, and officials hope to acquire more.

Pakistan operates five French submarines.

Its two Agosta-70s were acquired in 1979 and 1980, respectively, and despite upgrades they are widely acknowledged by analysts to be well past their prime and in need of replacement. Three air-independent propulsion (AIP)-equipped Agosta-90Bs, which are a development of the Agosta-70s, were commissioned from 1999 onward.

The Navy requires 12 submarines laid out in the Armed Forces Development Plan (AFDP) 2015 and a later revised plan.

Tuesday's proceedings created some confusion, however, with officials telling the committee that surplus submarines had been pursued from France, Germany, and the UK, but later acknowledging France had refused Pakistan's approaches with concerns over transfer of technology as one example.

Brian Cloughley, previous Australian defense attache to Islamabad, has said France has simply abandoned the Pakistani defense market to focus on the far more lucrative Indian one.

The mention of the UK was also surprising, considering the UK has not built or operated conventional submarines since the early 1990s, and sold its four Upholder-class subs to Canada where they now serve as the Victoria class.

Cloughley believes the Germans may not be willing or able to supply any surplus submarines either as they do not seem to have any, or at least any that Pakistan would want.

German firms offer new Type-214, Type-209/1400 mod, and Type-210 mod submarines for export.

However, Cloughley said there may be other possibilities.

Germany partnered with Turkey in 2011 to offer Indonesia a lease/new-build deal for Type-209 submarines. Indonesia, however, selected the South Korean improved Chang Bogo, a development of the Type-209/1400.

Turkish industry officials have told Defense News they are ready to offer Pakistan Type-209s if asked.

Turkey, one of Pakistan's closest allies and strongest defense industry partners, shelved its plans to upgrade its six Type-209/1200 Atilay class subs with AIP systems in favor of acquiring the Type-214.

However, Pakistani defense industry officials have said Islamabad would prefer a newer design.

It is uncertain if present circumstances have forced a rethink. "It's all supposition, and I'm afraid there doesn't seem to be an answer," Cloughley said.

Pakistan almost signed a deal for three Type-214 subs in 2008, raises hopes of Pakistan-Turkish submarine cooperation.

However, analyst Haris Khan of the Pakistan Military Consortium think tank said the deal floundered on the issue of financing after the then-Pakistan People's Party-led government signed an IMF loan agreement that derailed the sub acquisition plans.

He said the Type-214 deal was the centerpiece of the naval aspect of the AFDP, and that the first submarine would have been delivered in 2015. The naval aspect of the AFDP especially is in total disarray, he said.

It is unknown if the Type-214 was shelved until finances become available (some industry officials believe this was at least the intention at the time the deal collapsed), but attention subsequently switched to acquiring six AIP-equipped submarines from China.

Due to the need to decommission the Agosta-70s, Khan believes any refurbished submarines will be required to be "sailing under a Pakistani flag within 12 months."

Acquiring Turkish Type-209s remains possible, and despite Pakistan's predicament, Khan says "Under the present circumstances I don't see any collaboration between Pakistan and Turkey since Pakistan will only be locally producing Chinese submarines."

Whether the Chinese submarines are the S-20 export derivative of the Type-039A/Type-041 Yuan-class submarine, or a bespoke design, is unclear. But the Yuan has also been mentioned, and according to government officials the deal was supposed to be secured by the end of 2014.

If the deal transpires, Khan said it will be the largest ever Sino-Pakistani deal. He believes the submarines will each cost $ 250 million to $325 million.

Neither the Ministry of Defence nor the Navy would shed further light when asked. No answers were forthcoming to requests regarding the timeframe of the deal, whether the two Agosta-70s will finally be retired now the number of planned Chinese submarines has increased to eight, clarification on acquiring surplus Western submarines, or the status of the Type-214 acquisition efforts.

Should the Chinese deal go through, it will be a considerable relief, and be especially significant for the nuclear deterrent.

Pakistan inaugurated its Naval Strategic Force Command in 2012 in response to India's rapid nuclearization.

A potential force of 8 AIP-equipped Chinese subs and the three Agosta-90Bs "is a quantum leap in existing capabilities," said Mansoor Ahmed of Quaid-e-Azam University's Department of Defence and Strategic Studies.

Though acknowledging nuclear-powered attack boats are far more capable, he believes "An AIP [diesel-electric submarine] offers Pak the best bang for the buck. But it has to be supplemented with a commensurate investment in [anti-submarine warfare] capabilities to neutralize developments on the Indian side."

He said this will lay the groundwork for having a permanent sea-based deterrent equipped with plutonium-based warheads fitted to cruise missiles, "which is expected to be the next major milestone in Pakistan's development of a triad."

Ahmed acknowledges this "would pose fresh challenges for ensuring effective and secure communications at all times with the submarines for both India and Pak in addition to having a mated-arsenal at sea that would require pre-delegation of launch authority at some level for both countries.

"This would be an altogether new challenge that would have to be addressed for an effective sea-based deterrent."

Nevertheless, AIP-equipped conventional submarines "provide reliable second strike platforms, [and] an assured capability resides with [nuclear-powered attack and nuclear-powered ballistic missile submarines], which are technically very complex and challenging to construct and operate compared to SSKs, and also very capital intensive."

Pakistan likely to buy advanced S20 (Type 041 Yuan class) submarines from China

A senior Pakistani official recently told the UK's Jane's Defence Weekly that the country is likely to purchase six submarines from China. 


The official said the deal will be completed soon and an agreement is expected to be signed by both parties by the end of the year.

The Sina news web portal also cited a Pakistani official who said Islamabad and Beijing had settled the details for the arms sales and only the payment issue needed to be finalized.

The Pakistani source revealed that the S20 diesel-electric submarines, an improved model of the People's Liberation Army's Yuan-class submarines, may be the model that Pakistan will buy because China has actively promoted the model in the global market.

The S20 was developed based on the Type 039 submarine, which is referred to as Yuan class by the North Atlantic Treaty Organization and which measures 66 meters in length, 8m in beam and 8.2m in draft.

The surface displacement of the submarine is 1,850 tonnes and its submerged displacement is 2,300 tonnes, with a maximum speed of 18 knots. It can reach 8,000 nautical miles at 16 knots and it can carry 38 crew members in total for 60 days.

It uses a double hulled structure and its maximum dive depth is 300m.

Selling diesel-electric submarines to Pakistan will further consolidate China's role as a supplier for the country’s weapons and military equipment and enhance the Pakistan Navy's combat capability.

At present, the Pakistan Navy has five aging submarines bought from France — three Agosta 90B-class submarines purchased in the 1990s and two Agosta 70-class submarines, bought in the late 1970s.

In year 2014, China-Pakistan relationship could play a major role to build a massive submarine attack power for Pakistan Navy

Pakistan could sign a deal to buy up to six submarines from China before the end of 2014, senior Pakistani government officials have told IHS Jane's.

Pakistan's submarine fleet currently comprises Agosta 90B boats (second-of-class Saad is pictured) and ageing Agosta 70 vessels.
A Pakistani government minister revealed in March 2011 that China had offered to sell up to six submarines to Pakistan although he did not specify details of the boats on offer. Western officials in Islamabad suggest that China's subsequent international marketing of the 'S20' or Yuan-class diesel-electric submarine (SSK) suggests it could be a potential option for Pakistan.

A senior Pakistani government official told IHS Jane's that "the technical details are almost done. The present discussions are mainly about the financing details". A second Pakistani government official confirmed that "the contract is in an advanced stage and discussions will not linger on for too long. Realistically, we should have a deal by end 2014".

The submarine contract would further cement China's rapidly growing role as the main supplier of military hardware to Pakistan's armed forces and fill an important gap in Pakistan Navy (PN) capabilities. The PN is known to operate five French submarines: three Agosta 90B (Khalid-class) submarines purchased in the 1990s and two ageing Agosta 70 (Hashmat-class) boats dating from the late 1970s. In 2009, the PN sought to purchase three German-built Type 214 submarines, but the plan was put on hold due to costs that at the time were reported to be in excess of USD2 billion.

Recent Sino-Pakistan contracts of potential interest to Islamabad's strategic interests include China's agreement to provide two large civil nuclear reactors to be based close to Karachi. According to Pakistani officials China's Eximbank agreed to extend a USD6.5 billion loan for the two reactors.

Additionally, the Sino-Pakistani-built JF-17 Thunder fighter aircraft is reportedly the subject of talks between Pakistan and Saudi Arabia: a potential deal that Western officials said would not be discussed without Beijing's explicit consent.

 

COMMENT

A Sino-Pakistan submarine contract will be closely watched by Western officials for any signs that may suggest progression towards nuclear-powered boats. Pakistan's defence planners consider the absence of such a platform - which they would eventually want to see armed with submarine-launched nuclear ballistic missiles - as major disadvantage in a potential conflict with India.

However, Western officials believe China will hesitate to extend such advanced technology to Pakistan given the potential for a harsh reaction from the United States and its allies.
