Karachi Shipbuilding Boom Expected With Pakistan Navy Modernization

Pakistan is launching domestic construction of warships, submarines and missile boats as part of its ambitious naval modernization program in collaboration with China, according to media reports.

Chinese media reports have described a building program involving six of eight S-20 AIP-equipped variants of the Type-039A/Type-041 submarine under negotiation; four "Improved F-22P" frigates equipped with enhanced sensors and weaponry (possibly including the HQ-17 surface-to-air missile developed from the Russian Tor 1/SA-N-9); and six Type-022 Houbei stealth catamaran missile boats, to be built by Pakistan's state-owned shipbuilder Karachi Shipyard and Engineering Works (KSEW), according to DefenseNews.

Pakistan is expanding and modernizing its underwater fleet with 8 additional AIP-equipped submarines jointly built with China.  Mansoor Ahmed of Quaid-e-Azam University told Defense News that 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."

Expansion of KSEW in Karachi includes a new foundry, fabrication facilities to cover all aspects of ship construction, berthing facilities, and two graving docks of 26,000 and 18,000 dead weight tons, spread over 71 acres. A 7,881-ton ship lift transfer system will be completed next year. KSEW will expand to occupy facilities vacated by the Navy as it transfers from Karachi to Ormara. The Pakistan Navy Dockyard, which is adjacent to KSEW, already has facilities upgraded by the French during construction of Agosta-90B submarines.

The Pakistan Navy modernization efforts further expands existing China-Pakistan military manufacturing collaboration at Pakistan Aeronautical Complex (PAC) which has resulted in design and manufacturing of JF-17 fighter jets for Pakistan Air Force.

In addition to designing and building military hardware together, Pakistan and China are also increasingly collaborating on manufacturing consumer appliances and products. The Pakistan-China economic corridor project includes setting up of several special economic zones for this purpose. A good example of this cooperation is Haier-Ruba special economic zone in Lahore.  Haier-Ruba joint venture in Pakistan has announced plans to start manufacturing laptops and smartphones in Lahore this year, according to the JV chairman Shah Faisal Afridi. The Haier-Ruba group is one of the largest manufacturers of polyester yarn and home appliances in the country.

The growth of both military and civilian manufacturing industries is helping to develop Pakistan's human capital and creating job opportunities for engineers, technicians and other workers. 

Pakistan has taken a page from China's industrialization playbook which shows that the Chinese People's Liberation Army (PLA) led the nation's industrial growth, first with military hardware and then expanding into consumer and industrial product manufacturing.

#China building export version of one of its advanced #warships and will deliver it to #Pakistan as part of a major #arms deal. The ship has a fully loaded displacement of about 4,000 metric tons and is equipped with advanced radars and missiles. #Navy http://www.chinadaily.com.cn/a/201901/02/WS5c2c0e5aa310d91214051fba...

China recently started construction of an export version of one of its advanced warships and will deliver it to Pakistan as part of a major arms deal, according to China State Shipbuilding Corp, a large State-owned defense contractor.

It said the ship is a version of the Chinese Navy's most advanced guided missile frigate, without specifying its type.

In late December it said the ship is under construction at its Hudong-Zhonghua shipyard in Shanghai, noting it will be equipped with modern detection and weapon systems and will be capable of anti-ship, anti-submarine and air-defense operations.

According to the Pakistani Navy, the ship's class is Type 054AP, which means it is based on the Type 054A of the People's Liberation Army Navy. It previously said four such ships had been ordered.

Once constructed, the warship will be one of the largest and technologically advanced platforms of Pakistan's Navy and strengthen the country's capability to respond to future challenges, maintain peace and stability and the balance of power in the Indian Ocean region. It will also support the Pakistani Navy's initiative of securing sea lanes for international shipping by patrolling distant waters, it said in a statement on its twitter account.

Type 054A is the best frigate in service with the PLA Navy. Military sources said the ship has a fully loaded displacement of about 4,000 metric tons and is equipped with advanced radars and missiles. About 30 Type 054As are in service with the PLA Navy, observers said.

Cao Weidong, a senior researcher at the PLA's Naval Military Studies Research Institute, said that in the past, the Pakistani Navy would ask its Chinese contractors to use Western radars or weapons on ships constructed by Chinese shipbuilders because it believed Western naval technologies were better than Chinese ones.

"But it seems that all weapons and radars on the new ship will be Chinese products, which reflects our progress in the industry and the Pakistani Navy's confidence in our technology and capability," he said.

Cao said there are many nations selling frigates in the market, so Pakistan must have made thorough comparisons in terms of combat capability and costs.

"I believe the reason they chose our type is that ours is one of the few that can carry out all of the air-defense, anti-ship and anti-submarine tasks," he said, expecting the service of the Chinese frigate to substantially boost Pakistan's defense capability.

An insider in China's shipbuilding sector with knowledge of the Type 054AP program told China Daily on condition of anonymity that the ship is the largest and most powerful combat vessel China has ever exported.

"Based on pictures circulating on the internet, the ship will have vertical launch cells that can fire Chinese HQ-16 air-defense missiles and other kinds of missiles. Vertical launch cells will bring flexibility to the user in terms of weapons portfolio, thus giving it a stronger fighting capability," he said, adding that the Type 054AP is the best frigate Pakistan can access in the international market.

"The service of Type 054APs will double the combat power of the Pakistani Navy's surface fleet," he said.

Game-Changing #Chinese #Missile Aboard #Pakistan Frigates Could Dent #IndianNavy's #BrahMos Advantage. Chinese-made CM-302, which Pakistan will get, matches both the supersonic speed and the range of the #Indian Navy's BrahMos anti-ship cruise missiles. https://www.ndtv.com/india-news/game-changing-chinese-missile-to-pa...

An export variant of the YJ-12 missile, the CM-302, is likely to be the primary weapon on board four new Chinese frigates being built for the Pakistan Navy at the Hudong-Zhonghua shipyard in Shanghai.

The CM-302 matches both the supersonic speed and the range of the Indian Navy's BrahMos anti-ship cruise missiles, which have been deployed on several front-line frigates and destroyers of the Navy.

Senior defence officials monitoring the sale of new generation Chinese Type 054 frigates to Pakistan have told NDTV that the ships are likely to come armed with the CM-302, which they identify as a "new threat which represents a new capability."

But these officers also tell NDTV that "there is a long way to go for these missiles to become a credible threat for the Indian Navy" since the Pakistan Navy still lacks long-range sensors which need to target Indian platforms before a CM-302 can actually be fired.

"Possessing accurate targeting data, surveillance capability, and having the ability to penetrate a dense [Indian Navy] electronic counter-measures environment are a part of a complex matrix" that the Pakistan Navy's new frigates would need to overcome before they can attempt a missile launch.

Steel cutting ceremony for second Pakistani Navy Type 054A/P frigate

Still, the acquisition of the CM-302 onboard the new Chinese-built frigates that will be inducted from 2021 means a lethal new capability for the Pakistan Navy.

According to globalsecurity.org, a leading online resource of emerging military threats, "the highlight of the YJ-12 is not its range but speed. It can reach 'Double Three' or 'Double Four,' namely a range of 300 kilometres at Mach 3 (three times the speed of sound) or a range of 400 kilometres at Mach 4."

It is unclear if the Barak 8 Long Range Surface-to-Air Missile (LRSAM), deployed on India's newest Kolkata Class destroyers, have the ability to intercept a missile of this class. In response to a query from NDTV, senior Navy officers declined comment on whether the Barak 8 system has been test-fired against any supersonic anti-ship missile, let alone a missile that flies faster than Mach 2.

In an article in warontherocks.com, Robert Haddick, an independent contractor at the US Specials Operations Command, has said "the YJ-12 is the most dangerous anti-ship missile China has produced."

According to Mr Haddick, "the arrival of the YJ-12 is one more indication of how the US Navy is falling further behind in the missile competition against China, exposing flaws in operating concepts that US and allied commanders and policymakers have relied on for years."

News of the possible Pakistani acquisition of the YJ-12/CM-302 broke on twitter late last month when the China State Shipbuilding Corporation organised the steel-cutting ceremony for the second of the four Type 054A/P frigates that Pakistan is receiving. A digital image (shown below) emerged which showcased a CM-302 missile mounted on a launcher on a Pakistan Type 054 frigate. It is unclear if this detailed digital image was sourced from an official release or was the work of a Naval analyst.

Key Points
The Pakistan Navy has conducted another test-firing of an indigenously developed cruise missile
The weapon is being tested amid heightened tensions with India over the long-standing Kashmir dispute
The Pakistan Navy has conducted another test-firing of what appears to be a shipborne variant of an indigenously developed cruise missile.

The weapon was fired from its latest Azmat-class patrol craft, PNS Himmat (1027), in the North Arabian Sea, the Pakistan Armed Forces' official media communications group known as the inter-services public relations (ISPR) office revealed on 23 April.

In January 2018, Himmat conducted a similar test-firing of the weapon. On both occasions, the ISPR office stopped short of disclosing the type of missile used in the firings, only noting that it has anti-ship and land-attack capabilities, and that the weapon has been developed in-country.

The test announced in April 2019 was also described as one that has "accurately hit its target on land", but no further details were given on this, including the type of target deployed, and its distance from Himmat at the time of firing.

Images of the launch released by the ISPR office suggest a weapon length of between 6 m and 7 m, when taken in relation to Himmat 's overall beam. Based on its visible markings, it is probable that the missile is the 'Harbah', which is shipborne variant of Pakistan's indigenously developed Hatf 7 (Babur) short-range cruise missile.

Pakistan is known to be pursuing air-, ship-, and submarine-launched variants of the Babur cruise missile to complement its line-up of longer-ranged ballistic missiles.

Pakistan Navy’s Blue Water Ambitions
February 14, 2019

https://www.globalvillagespace.com/pakistan-navys-blue-water-ambiti...

Shahid Raza |

Pakistan Navy is the guardian of Pakistan’s maritime boundaries. An ever-increasing threat of terrorism at sea, piracy and fast-changing geo-security dynamics in the Indian Ocean Region (IOR) have encouraged Pakistan Navy to embark on an ambitious modernization plan to commission new warfare assets to develop new capabilities which would enable the Navy to operate in blue waters by 2030. The list of assets being acquired or developed by them includes the following.

1: Type-54A/P Frigate
The advance Type-54A/P is a highly potent naval frigate which is currently the backbone of the Chinese naval fleet. This cutting-edge vessel has a displacement of over 4000 tons. It is equipped with an advanced radar and sensor suite, integrated mast assembly. The main weapon of this frigate is a 32x cell vertical launch system armed with HQ-16 Surface to Air Missiles along with anti-ship cruise missiles and a sophisticated self-protection system. Pakistan is acquiring 4 such vessels from China to replace its obsolete Amazon-class frigates, delivery is expected to start by 2021 and all are expected by 2025. When it joins service, it will be the most powerful warship in Pakistan Navy’s inventory enabling the force to operate in blue waters.

2: Hangor Class Submarine
Pakistan Navy’s submarine force is more than 50 years old. Pakistan was the first operator of submarines in South Asia. Currently Pakistan Navy fields French made Agosta class submarines, some of which – the Agosta 70s are reaching towards the end of their useful life. Therefore, Pakistan Navy has embarked upon a replacement and modernization program to overhaul the Agosta-90B submarines in Turkey to modern standards and acquire 8 new built Hangor class submarines from China, four of which will be built in Pakistan. They are expected to be delivered between 2021-28. Not much is known about these submarines – but they are believed to be highly advanced variant of mainstay Chinese diesel-electric submarines of unspecified class.

3: Jinnah Class Corvette
Pakistan Navy is acquiring 4 newly built Ada Class Corvettes from Turkey to boost its littoral defence capabilities. These are stealthy warships displacing 2400 tons each and are specifically designed for maintaining area sea denial. Delivery is expected by 2025. It is believed that Pakistan will seek to arm them with its domestically developed Harba anti-ship Cruise Missile system. According to details, two of these ships will be built in Pakistan and when they join service, they will be named the Jinnah Class in the honour of Pakistan’s founding father. In addition to Jinnah Class, the Navy is also planning to put its existing fleet of F-22P Frigates through a Mid Life Upgrade program to extend their life and capabilities.

4: Maritime Air Wing
In order to protect coastal installations and to attack enemy assets at sea, the Navy has started an ambitious program to develop state of the art maritime attack capability. This includes the induction of JF-17 Thunder fighters with anti-ship capabilities into the Minhas squadron based in Karachi. Another squadron with identical capabilities will also be coming up soon. The Navy has recently inducted an ATR aircraft which was specifically upgraded in Germany for maritime strike role. The Navy is also looking for a replacement for its P3C Orion maritime attack aircraft and to induct unmanned aircraft with similar capabilities.

5: Offshore Patrol Vessel
An order has been placed for 2 OPV-1800 vessels from Netherlands based firm, Damen first of which is under construction in Romania, with expected delivery in 2022. The OPV displaces at 1900 tons each and as per the MoDP, the multi-mission OPV “is especially suited for anti-surface & anti-air operations, maritime security operations, day [and] night helicopter operations, combat search and rescue, and surveillance and intelligence gathering operations.”

6: Coastal Defense System
In a bid to boost its coastal defense capabilities, the Pakistan Navy has inducted the Zarb Coastal Defense System which is based on the Chinese C-602 anti-ship cruise missile system. Pakistan Navy is also believed to be interested in acquiring an anti-ship Ballistic Missile system to add more capability to its coastal defenses in the future, specifically to target the aircraft carriers being acquired by the Indian Navy.

7: Second Strike Capability
Ever since the induction of the Naval Strategic Forces Command and the successful tests of the Babur-III Submarine Launched Cruise Missile System, the Navy has been working to develop Pakistan’s second strike capability. It is believed that in addition to the induction of Nuclear armed Babur-III missile, there is keen interest in the indigenous development of a nuclear-armed, nuclear-propelled submarine to consolidate Pakistan’s long term Second Strike options.

8: Intelligence Assets
Intelligence gathering is an indispensable part of modern warfare, thus Pakistan navy has been actively working to induct intelligence gathering assets including Unmanned Aerial Vehicles (UAVs), a 3000-ton survey ship and by levering Air Borne Early Warning (AWACS) assets of the Pakistan Air Force, as well as ground-based sensors.

9: Logistical Assets
Pakistan Navy requires advance logistical facilities to augment its acquisition of new warships, therefore the Navy recently commissioned a 17000 ton Fleet Tanker which was built in Karachi with help from Turkey to supply fuel, water and ammunition to Pakistan Navy’s combat and auxiliary units. It is also equipped with state-of-the-art medical facilities to support the Pakistan Navy during war and disaster relief missions.

10: Gwadar Base
With an expansion in assets and capabilities, the Navy requires a large new base to accommodate these assets in a safer location, far from the reach of the Indian Navy. Gwadar is where the biggest ever naval base of the country, aptly named ‘Jinnah Naval Base’ is being constructed. This base will also be augmented by support facilities and a new ship manufacturing and servicing facility. This base will be capable of berthing most of Pakistan’s surface warships, submarines, and aircraft in the future.

Jinnah Naval Base – Navy expands strategic outreach to West Coast, Persian Gulf

https://www.pakistantoday.com.pk/2016/01/13/jinnah-naval-base-navy-...

The base is situated 350 km west of Karachi and 285 km east of the Gwadar Port, and has been connected with China-Pakistan Economic Corridor (CPEC).

“With the development of this base, Pakistan has acquired the capacity to secure naval trade in these waters. Moreover, we have expanded Pakistan naval forces’ outreach towards the west coast into the Strait of Hormuz where all the oil traffic flows in and out,” an officer at the base told Pakistan Today during a recent visit to the base at Ormara which is otherwise restricted for media.

“Karachi would remain our focus for the foreseeable future. However, Jinnah base would reduce reaction time of Pakistan Navy to six to 8 hours in case of any adversity,” the officer said, adding that the base had a berthing facility “for anything from warships to submarines and from heavy ships to warplanes”.

Asked whether or not Gwadar would also act as a naval base for Pakistan, the officer said that Gwadar would act purely as a commercial base.

“Though Pakistan Navy has a small base at Gwadar, its main focus would be security of Gwadar. Jinnah base, on the other hand, would be a purely naval base which would help maritime forces monitor the entire coastal area from Ormara to the Gulf waters,” the officer said.

Rear Admiral (r) Pervez Asghar, an expert on naval defence, told Pakistan Today that Pakistan Navy had developed four bases along the coastal areas of Balochistan including Ormara, Pasni, Jewani and Gwadar which had helped expand its ‘strategic outreach’ towards the west coast.

“In the past, we only had one [naval] base at Karachi and our military installations were vulnerable to any Indian adventure. However, with the development of these new bases towards the west coast, not only do we have alternative options to defend our positions, our reaction time has also decreased significantly in case of any attack,” the retired naval admiral said.

He said that the navy now also had a submarine base at Ormara. “We have developed Pakistan marine corps to thwart enemy designs of amphibious landing around the coastal areas,” he added.

“Pakistan Navy is now well placed to secure all sea lines of communications (SLOCs) emanating from the Persian gulf towards Pakistan. Moreover, the naval infrastructure including Radars and communication gadgets, have now been able to overlap each other – a capability we had severely missed in the past,” he added.

He said that the new bases had also helped secure Gwadar Port as there was no military presence on the port due to its being commercial in nature.

“Now, navy’s special forces are better placed in Ormara to secure Gwadar Port and nearby sea routes. Moreover, Ormara base would also help neutralise the enemy’s narrative that they would be able to block Karachi’s harbour in case of a showdown,” he added.

Asghar said that Pakistan had also developed a jump-off base for Pakistan’s maritime aircraft at Pasni.

He said that Pakistan Navy had recently raised another naval station at Turbat, namely PNS Siddiq for P-3c Orion aircraft.

“These P-3cs are capable of flying over 14 hours nonstop without refueling. They have stealth technology and can fly below the radar and strike India’s Eastern coast. Pakistan Navy has also developed Naval Base Jewani, about 60 km from Iran to help expand its outreach into the Gulf waters,” he added.

Jinnah base would act as an alternative option for Pakistan Navy to Karachi where all the logistic and technical support for berthing navy’s ships and even submarines were available.

“We have developed the required facilities for technical repair of ships and submarines at the base. It is an alternative arrangement to the Karachi base and can easily meet our defence requirements. However, Karachi dockyard would still be the center for major overhaul or repair,” the Jinnah base officer said.

#Pakistan wants to accelerate new #shipyard project in #Gwadar. It'll be focused on meeting the Pakistan Navy's requirements and #defense export opportunities, alongside pursuing commercial #shipbuilding contracts to strengthen revenue streams | Jane's 360 https://www.janes.com/article/88859/pakistan-wants-to-accelerate-sh...

Pakistan's Standing Committee on Defence Production has called for work to be accelerated on the country's long-delayed programme to develop a naval shipyard in Gwadar, a port city on Pakistan's southwestern coast.

A statement by Pakistan's Senate on 27 May said its defence production committee had "laid stress to expedite the completion [of the shipyard]", which was first proposed in 2008.

The Senate added that the construction project should be overseen by the country's Ministry of Defence Production, which should "supervise all work [including] conducting feasibility studies [and] infrastructure to [support] future load and density requirements".

The new shipyard would be focused on meeting the Pakistan Navy?s requirements and defence export opportunities, alongside pursuing commercial shipbuilding contracts to strengthen revenue streams, said the Senate.

#Pakistan 2nd country after #Indonesia to purchase #Turkey’s anti-torpedo 24 different launcher cells system for Pak Navy. The countermeasure tactics of the system include evasive maneuvering, different deployment patterns and acoustic jammers/decoys.
http://sabahdai.ly/nkusm9

urkish defense giant ASELSAN will meet the Pakistani Naval Forces' countermeasure system needs against torpedo missiles with its domestically developed system, making Pakistan the second country to import it.

The Zargana Anti-Torpedo Countermeasure System for submarines was developed by the defense company for foreign purchasers as a different version of the domestic system. The system Pakistan is set to buy will also be adapted to the country's Agoste 90B class submarines.

With the purchase, Pakistan becomes the second country after Indonesia to use the Zargana, which is the first and only system developed in Turkey and superior than its counterparts worldwide.

The countermeasure tactics of the system include evasive maneuvering, different deployment patterns and acoustic jammers/decoys.

After detecting and classifying the threat, the system determines the most appropriate avoidance tactic against torpedoes targeting submarines while taking into account environmental conditions with real-time data provided by the submarine.

Acoustic jammers deployed by the system prevent the torpedo from detecting the submarine's location, while acoustic decoys imitate the submarine and deceive the torpedo.

The Zargana provides the highest level of defense against torpedoes with its autonomous operation and quick reaction time and can be integrated into operator-controlled inputs or submarine systems that provide real-time data.

The missile and launcher system has up to 24 different launcher cells, single or salvo firing with high reliability and fireproofing properties.

In recent years, Turkey has taken a noticeable leap forward with innovative engineering moves in the defense industry and domestically-developed military equipment and combat vehicles in almost all fields of warfare.

According to the Turkish Exporters Assembly (TİM) data, the export performance of the sector in 2018 increased by 17 percent compared to 2017. The industry broke its own record of $1.7 billion in November and moved the record up to $2.03 billion by the end of the year. The defense and aerospace industry, whose export performance has been hovering between $1.5 billion and $2 billion, exceeded the threshold of $2 billion for the first time.

The U.S. was the top destination for Turkish defense exports, and the sector's sales to the country soared by 41 percent, reaching $64.2 million. The U.S. was followed by Oman with $49.4 million and Germany came in third place with $18.4 million. Defense exports to Germany rose by 25 percent in January.

Turkey has also exported defense products to new destinations, including Guatemala, India, Guiana, Tanzania, Trinidad, and Tobago.

Importance Of Nuclear Submarines For Pakistan – OpEd
July 2, 2019 Anjum Sarfraz*

https://www.eurasiareview.com/02072019-importance-of-nuclear-submar...

A submarine is a very powerful platform, because of its stealth features and ability to operate covertly. It plays vital role in naval warfare and as a strategic weapon carrier. It can operate under water for a considerable duration, hence cannot be easily detected; therefore it has become an essential constituent of modern navies.

Submarines (subs) are of four types, which differ mainly because of their propulsion system and weapons carried on board. Diesel powered attack submarines (SSK) while on surface use diesel engines for propulsion, and while traversing under water it runs on batteries which have limited endurance. To recharge, conventional subs have to come up to periscope depth for snorkeling very often, keeping in view battery conditions. It is very vulnerable while snorkeling; chances of detection by Anti-Submarine Warfare Forces (ASW) like maritime patrol aircraft, helicopter, and surface platforms are very high. It is relevant to mention that subs have no weapons against the aircrafts.

The endurance of SSKs has been increased by installing Air Independent Propulsion (AIP) system. This allows additional submerged time and is particularly useful during evasion and transiting through areas of concentrated ASW activities. The advent of this technology has enhanced the submerged endurance but is still restricted in speed. The maximum speed is around 15 knots but it moves 3-5 knots while submerged to conserve batteries. These generate very less noise, hence difficult to detect.

Maximum operating depth is around 300 meters and tonnage 1000 to 3500. Weapons carried are anti-ship and anti-submarine torpedoes and sea mines. Also carry medium range (800Km) anti-ship and land attack cruise missiles. Next generation is nuclear propelled attack subs (SSN), nuclear powered guided missiles (SSGN) and nuclear powered ballistic missile carrying subs (SSBN). These have a nuclear power plant for propulsion with almost unlimited endurance, speed around 30 knots on surface as well as submerged, and maximum operating depth more than 500 meters. These are much heavier and noisy as compared to conventional subs. The displacement is from 4000 to 18000 tones. These are designed to remain deployed for much longer duration; only human fatigue is the restrictions. The main role of SSNs and SSGNs is to operate as ASW platforms for a carrier task force and convoy support operations.

-------


It is obvious that Indian navy has sufficient knowledge of construction and operation of nuclear subs. PN has two Agosta and 3 Agosta 90 B (Khalid class) subs with AIP system. Two have been built in Karachi Shipyard and Engineering Works (KSEW). These have medium range land attack cruise missiles with nuclear warhead. In addition order for 8 latest versions of Chinese conventional subs with AIP system has been placed. Four will be built in Pakistan in KSEW. However, for long range land attack missiles and sustained deployment PN needs to have at least two nuclear submarines with ballistic missiles. Keeping in view Indian second strike capability, our government needs to start the project at the earliest. In the meantime PN may actively consider sending their officers and sailors to China or Russia for training on their nuclear submarines.
