Indian Navy Swears By Its Tavor Family Of Small Arms & Its Four Upgraded Class 209/Type 1500 SSKs
As far as orders already placed for new-build vessels go, four 6,700-tonne Project 15B guided-missile destroyers (DDG) will be built by Mazagon Docks Ltd (MDL) as will seven Project 17A guided-missile frigates (FFG) and all these 11 warships will be using LM-2500 marine industrial gas-turbines for propulsion, two 110-metre cadet-training ships are being built by ABG Shipyard at a cost of Rs9.7 billion (under a contract signed in June 2011), five 2,500-tonne offshore patrol vessels (OPV) to be built by Pipavav Defence and Offshore Engineering Company Ltd, eight Landing Craft Utility (LCU) to be built by Garden Reach Shipbuilders & Engineers under a Rs23 billion contract inked in September 2011, 80 fast interceptor craft (FICs, to be imported from Sri Lankas Solas Marine) and 15 FIC-1300s (being imported from Chantier Naval Couach of France). The FICs are small high-speed boats for harbour and offshore oil rig and counter-terror patrols, meant for use by the Sagar Prahari Bal, post-26/11, and hence have no relevance to any traditional naval blue- or green-water operations. A contract to import two and indigenously built six South Korea-origin minesweepers (derived from Intermarine of Italys Lerici-class GRP-hulled minehunter, but re-engineered by Kangnam Corp) is also to be signed soon. RFPs for the indigenous construction of four 20,000-tonne LPHs under a Rs170 billion contract have been issued and all the responses have been received, with the frontrunner being DCNS of Frances Mistral BPC design. The MoD-owned shipyard expected to win the contract for licence-building the latter two of the four LPHs is Vizag-based Hindustan Shipyard Ltd, which is likely to enlist the services of Larsen & Toubro as its strategic shipbuilding partner. Construction of the first locally built LPH is expected to commence by 2015. Also awaiting approval from the MoD is a proposal for a dozen ocean-going AOPVs. Meanwhile, the first 37,000-tonne Indigenous Aircraft Carrier (IAC)INS Vikranthas just adhered to its float-out schedule. Its keel had been laid in February 2009 after hull-fabrication work began in November 2006. It was then estimated then that the vessel would be ready to float in two years. The formal launch now is expected to take place in the first quarter of 2012. The MoD has committed Rs32.61 billion for the first phase of the IAC. The delays were caused last year when a heavy-duty vehicle motorised vehicle transporting the marine reduction gearboxes and propellers from Wärtsiläs factory at Khopoli suffered a fatal road accident. In another development, GRSE has successfully re-engined the first of three 57-metre long 589-tonne Project 1241.2 Molniya-2 ASW corvettes (INS Abhay, INS Ajay and INS Akshay) of the IN. Sea trials of the re-engined INS Abhay have been successfully completed, with work involving the replacement of Russia-made M504 radial engines with high-power-to-weight MTU-1163 engines. Work is now underway to procure through competitive tendering three sets of ultra-low-frequency towed-array sonars (from either ATLAS Elektronik of Germany or US-based L-3 Communications/Ocean Systems) for installation on board these three ASW corvettes.
Depleting Undersea Warfare Capabilities
The INs 30-year Submarine Construction Plan, which the apex Cabinet Committee on National Security (CCNS) had approved in July 1999, was crafted purely by the MoDs bureaucrats and the DRDOs technocrats, and both of them never even bothered to consult the IN or seek the Navys vital inputs on operational requirements. The 30-year plan for constructing three SSBNs, and 24 conventional submarines (SSK) to be built in two simultaneous construction ventures: one building six SSKs (these being the six Scorpenes now being fabricated by MDL) and another building six new-generation Russia-designed SSKs (as the thinking in 1999 was that since the Larsen & Toubro-led Indian industrial consortium was engaged in building the three projected SSBNs in cooperation with their Russian counterparts, this same model of bilateral industrial cooperation could also be extended to encompass the licence-building of six Amur 1650-class SSKs). Consequently, based on the experience gathered in fabricating SSKs of both Western and Russian origin, India could acquire the expertise required for building another 12 SSKs of an indigenous design. This plan, to say the least, was outrageously flawed on several counts, as was the decision in the early 1980s to procure a mixed fleet of SSKs, with six single-hulled SSKs being of German origin and eight double-hull SSKs of Soviet origin. When the IN was forced to go for two types of SSKs, it rightly requested the MoD to not only acquire the first two single-hulled SSKs off-the-shelf, but also insisted that the MoD licence-build at least another four of them at a custom-build facility to be set up by MDL andmost importantly, the selected SSKs entire design package be bought over by the MoD, meaning only MDL would be able to build this SSK design and the IN would be the sole operator of such SSKs. The MoD agreed and consequently, four 1,810-tonne Class 209/Type 1500 SSKs (two built by Germanys Howaldtswerke-Deutsche Werft, or HDW) were commissioned between 1986 and 1994, while at the same time eight double-hulled 3,076-tonne Type 877EKM Kilo-class SSKs were procured off-the-shelf from the USSR between April 30, 1986 and July 19, 2000. The contract for procuring four Class 209/Type 1500 SSKs was inked on December 11, 1981 and the first two SSKs (S-44 Shishumar and S-45 Shankush)--built by HDW--were inducted into service on September 22 and November 20, 1986, respectively. The remaining two (S-46 Shalki and S-47 Shankul) were licence-built by MDL and entered service on February 7, 1992 and May 28, 1994. Earlier, plans for building another two such SSKs were put on hold in 1987 an innocuous telegram from Indias Ambassador in Germany, inquiring if the 7.5% (of the per-unit contracted value) sales commission was to be paid for the 5th and 6th SSKs as for the first four, set in motion a CBI witch-hunt and subsequent political cover-ups, all of which finally died a natural death only in 2006. However, till this day, no satisfactory explanation has been given by the MoD about the reasons for not resuming the construction of additional Class 209/Type 1500 SSKs post-1994, especially since the MoD, through MDL, remains the legal owner of all IPRs relating to the Class 209/Type 1500 SSK. If it was possible for all four Class 209/Type 1500 SSKs to undergo mid-life refits and upgrades from 1999 to 2005 (which have extended their operational lives to between 2016 and 2024) and be retrofitted with ATLAS Elektronik-supplied ISUS-90 suites (comprising new-generation combat management systems and new sonar suites), then why was the option to series-produce at least six more such SSKs not exercised? Had these six SSKs been built, then they could even have been fitted with customised fuel cell-based AIP plug-ins that were developed by the German Submarine Consortium as far back as 2000 specifically for the Indian Navy and have been on offer for the past decade. However, since the decision was made in 2005 to go for six single-hulled Scorpene SSKsunder Project 75for replacing the eight remaining Type 877EKM Kilo-class SSKs between 2015 and 2018 (the Kilos have been due for decommissioning since 2010), it now makes perfect sense to order at least another three Scorpenes, which, along with the fifth and sixth Scorpenes now being fabricated by MDL, will in all probability be equipped with the DCNS-developed Module d'Energie SousMarine Autonome (MESMA/Autonomous Submarine Energy Module), which along with its shore-based support infrastructure, should cost $80 million per unit. Boats of this type will be known as Super Scorpenes.
The programme to acquire six new-generation single-hulled SSKs under Project 75I, expected to reach the contract negotiations stage only by 2014, now calls for the procurement of boats fitted with a proven air-independent propulsion (AIP) system. Initially (between 2006 and 2011), the IN evaluated offers from Sweden, Germany, Russia, Spain and France. Kockums A26 SSK, an improved version of the Gotland-class SSKs; will displace 1,930 tonnes, and use a Stirling engine-based AIP system (which is already operational with the SSKs of Japan, Singapore and Sweden) that uses diesel and liquid oxygen and is coupled to a 75kW generator to recharge the SSKs batteries. Another notable feature of this SSK is its relatively light manpower requirement of up to 26 personnel, which helps to keep running costs down. The A26 has also been engineered to have a high degree of resistance to shock and underwater explosions, along with a highly stealthy design in terms of radar and acoustic signatures. Germany's Thyssenkrupp Marine Systems, which has developed two types of AIP systems developed by Siemens (the proton exchange membrane hydrogen fuel-cell powering the Type 212 SSK and the polymer electrolyte membrane hydrogen fuel-cell for the 1,680-tonne Type 214 SSK), is offering the latter, which can dive down to more than 400 metres and has a range of 22,224km. Navantia of Spains 2,426-tonne S-80 SSK makes use of an ethanol-based AIP system, while the 2,700-tonne Amur 1650 SSK (with a maximum diving depth of 300 metres and a crew complement of 35) is being proposed with the Kristall-27E AIP system using oxygen-hydrogen fuel-cells. It has since emerged that the IN has now shortlisted only three prospective candidates for Project 75I: the Super Scorpene equipped with MESMA, the A26 with Stirling engine, and the Type 214 SSK, which is already operational with the navies of Greece, Portugal and South Korea and in future with Turkey. From a technology maturity standpoint (which the IN insists upon), it would therefore appear that while the MESMA and Stirling AIP systems along with Siemens AIP system (based on two polymer electrolyte membrane 120kW fuel-cell modules driving a Siemens Permasyn Type FR6439-3900KW low-speed permanently excited electric motor) meet the INs qualitative requirements (QR), the Kristall-27E and the indigenous AIP system being developed (since 2002 and due for sea trials by only 2013!) by the DRDOs Ambarnath-based Naval Materials Research Laboratory (NMRL), along with the Kochi-based Naval Physical and Oceanographic Laboratory (NPOL), dont qualify. In the end, therefore, the Project 75I contest is likely to be between the Super Scorpene and the Type 214 SSK.
The INs first of three projected SSBNsArihantcontinues to remain berthed under a shed at the Ship Building Centre (SBC) near the Naval Dockyard in Vishakhapatnam. Once its PWR goes critical by next February, and will undergo all the standard harbour and sea trials common to all nuclear-powered submarines. The vessel has already completed several trim dives alongside, an operation that requires very detailed trim calculations for the first of the class. This is a very critical operation for flooding and de-flooding the ballast tanks by the on-board pumps. SBC has all the facilities to produce external steam and power for the Arihant. With external steam and power, the SSBNs propulsion, steering gear and associated systems, electronics and generators can be set to work and tested during harbour trials. When all the systems are expected to be cleared by the Submarine Overseering Teams over the next 65 days, the full ships complement will join the boat for very detailed safety and emergency training. This will be a very critical part of the commissioning, and will be overseen by a specialist submarine-qualified Vice Admiral responsible for nuclear propulsion safety from Naval Headquarters (NHQ). After all the harbour trials are completed, the Arihants on-board PWR will go critical at low power and be gradually worked up to higher power to enable the hull to go to sea. When this happens, INS Arihant will report Underway on Nuclear Power. The next phase of trials and evaluations will include sea trials on surface at various speeds, and when the confidence of the crew complement rises, the SSBN will carry out its first shallow dive by the latter half of next year, going deeper progressively at various speeds. On return from every diving trial, several mandatory structural checks on the hull and PWR performance will be carried out by specialists, and the final deep dive to maximum operating depth will culminate in the SSBN embarking upon Phase 3 of its sea trials schedule, this involving weapons-firing trials. Only after all three phases of trials are completed will the Arihant be commissioned sometime before 2014. However, should something go wrong, the IN will require the services of a Deep Rescue Submarine Vessel (DSRV), which remains elusive despite efforts to acquire a few from either the US or Canada. Instead, it is relying on a diving support vessel with a decompression chamber, and has also contracted the US Navy to fly in a DSRV and deploy it to the site of the accident.
The DSRVs absence will also be felt by the crew complement of the K-152 Nerpa (the Seal), a Project 971A Shchuka-B (Akula-3) SSGN, which was commissioned as the INS Chakra on December 29 at Bolshoi Kamen in Russias Primorye region. Obtained on dry-lease for a period of 10 years (with an option to increase it by another five years) the K-152 Nerpa (the Seal), a Project 971A Shchuka-B (Akula-3) SSGN whose keel was laid down in 1986. The Letter of Intent for leasing the SSGN under Project India was inked on February 8, 2002 in New Delhi during the 2nd session of the IRIGC-MTC between the then Russian Deputy Prime Minister Ilya Klebanov and the then Indian Defence Minister George Fernandes. On November 24, 2002 final price negotiations for the lease began took place during Klebanovs visit to New Delhi. Rosoboronexport officials then stated that fabrication of the two SSGNs will resume after India pays the first tranche of $100 million as per the contract. The final lease contract for only the Nerpa for the time-being, valued at US$920 million, was inked in New Delhi on January 20, 2004. The Nerpa is the 15th SSGN and the second Akula-3 built under project 971 (codenamed Shchuka) and was designed by the St Petersburg-based Malachite Marine Engineering Bureau under Chief Designer Georgy Chernyshev who, after his death in 1997, was succeeded by Yuri Farafontov. While the Severnoye Machine-Building Enterprise has to date built seven Akulas, the Amursky Shipbuilding Plant has built eight. The Akulas built by the former have been named after land-based beasts of prey, while those built by the latter bear the names of fish and other marine animals. The latest version of the Akula SSGN is the Akula-3 and its dived displacement is 13,800 tonnes, full dived speed is 33 Knots, operational diving depth is 520 metres and maximum diving depth is 600 metres. The SSGN can carry up to 40 weapons ranging from supersonic anti-ship cruise missiles to torpedoes to sea mines. The Akula-3 comes with a two-stage noise supression system and all compartments are shockproof, which results in a five-fold reduction in the level of acoustic fields when compared to the Akula-1. Both the Nerpa and its sister vessel, the K-335 Gepard, are the first3+ generation nuclear-powered submarines of Russian origin that have a centralised integrated platform management system (IPMS) and a combat management system (CMS), all of which have resulted in the crew complement being reduced to only 73. The IPMS is called Molibden-1 and has been developed by the Krylov Central Research Institute, while the CMS was developed by the St Petersburg-based Aurora Research & Production Association FSUE, which has also supplied the 15-module submarine monitoring-cum-data recording system. The integrated sonar suite has been developed by Morphyspribor Central Research Institute and Akvamarin JSC, and built by FSUE Taganrog Priboy Plant. The Nerpas most visible distinguishing features are the more elongated and slightly pugged barriers (to its port and starboard) for retractable gear and a more aft-mounted compact gondola mounted on the aft vertical fin, which houses a low-frequency thin-line towed-array sonar suite.
INS Chakra is due to arrive in late January next year at Vizag, HQ of the INs eastern Naval Command, after undertaking a ferry voyage through the Western Pacific and entering the Bay of Bengal after transiting through the Malacca Straits. In January 2007, work began on modifying (at a cost of $135 million or Rs5.4 billion) the SSGN to accept on board up to 18 Novator 3M53E/3M14E multi-role cruise missiles as well as TEST-71ME and TEST-71ME-NK torpedoes (built by Russias DVIGATEL FSUE and Region State Research & Production Enterprise) that will be fired from the SSGNs six 533.4mm and four 650mm tubes. The hull will feature twin flank-array sonars for being used as a torpedo approach warning system, and a stern-mounted distinctive bulb on top of the rudder housing a low frequency thin-line towed active/passive sonar array. INS Chakras crew complement will be all-Indian. Some 300 IN personnel, comprising three sets of crews, have for the past five years been extensively trained and type-rated to man the SSGN at a specially built secure facility in the town of Sovnovy Bor near St Petersburg. The IN will be using this SSGN for the following:
·Undertaking anti-submarine patrols along the southeastern and southwestern parts of the Indian Ocean.
·Establishing a series of restricted submarine patrol sectors in far-flung areas of the Indian Ocean to allow persistent undersea warfare operations unimpeded by the operation of, or possible attack from, friendly or hostile forces in wartime; and without submerged mutual interference in peacetime.
·Perfecting the art of communicating with submerged SSGNs using VLF, UHF SATCOMS, SHF and EHF frequencies, and using maritime surveillance/ASW aircraft as mission controllers for the SSGNs.
·Exploring ways of evolving a robust and nuclear first strike-survivable two-way communications system comprising shore-based, airborne and submerged elements to ensure that the SSGNs commander receives explicit rules of engagement and strategic targeting data.
· Analysing the pros and cons of having either a decentralised C³ network for certain types of missions, or a tightly centralised network by developing command automation via network-centric warfare strategies.
· Trying to achieve submarine internet protocol connectivity and working on solutions that will deliver a reduction in time latency, increased throughput and the ability to maintain communications at speed and depth. One technology demonstrator already developed by the DRDO by still classified comprises a submarine- or air-launched recoverable tethered optical fibre (RTOF) buoyant 450mm diameter buoy which, upon reaching the surface, deploys a low-frequency acoustic projector to a preset depth, enabling reach-forward from the Fleet Commands SSGN operating authority via a built-in SATCOM antenna. A pager is then activated via SATCOM and paging and target cueing messages are sent to the submarine at a data rate of 2.4 kb/second. Consideration is also being given to the use of a swimming communications device, such as an autonomous underwater vehicle (AUV), which would surface to exchange data via SATCOM via a repeatable 32kb/second communications window, and then return to the host SSGN for download. A prototype AUV for undertaking such operations has already been developed by the DRDO.
· Use of RTOF buoys, which provide data rates of around 32kb/second while the SSGN is cruising at 8 Knots and is more than 244 metres underwater. The INs longer-term network-centric vision includes the use of distributed undersea networks, offering the submarine a network of known underwater nodes to be used to download large amounts of information, while remaining at depth. The concept calls for a field of acoustic sensors, UHF local area network-linked platforms and SATCOM buoys.
· Establishing a protocol for undertaking deep-sea crew rescue and salvage operations using the INs yet-to-be-acquired remotely operated rescue vehicles (RORV) and related launch-and-recovery system (LARS) and a fully integrated self-contained emergency life support system (ELSS) package.
However, it must be noted that the acquisition of INS Chakra will by no means give India the long-awaited third leg of the nuclear triad. Neither will the SSGN come under the tri-service Strategic Forces Command. Simply put, the Akula-3 SSGN will be armed with Club-S anti-ship/land attack cruise missiles which, along with the on-board torpedoes, will give the SSGN a formidable sea-denial capability along a 200nm arc contiguous to Indias coastline as well as in the Indian Ocean Region. Russia, which adheres to the Missile Technology Control Regime along with the NPT and START-2 treaties, is obligated to ensure that INS Chakra does not carry any nuclear weapon whatsoever. Furthermore, the SSGNs employment in wartime too will be highly restricted and its rules of engagement will have to be cleared with Moscow, thus limiting Indias operational sovereignty over the SSGN. In fact, it is due to this very reason that Navy HQ has been insisting since the early 1990s that the DRDO accord greater priority to developing indigenous SSGN solutions (for protecting the projected fleet of three deployed SSBNs) to ensure that Indias nuclear deterrent, in the long run, remains effective, enduring, diverse, flexible, and responsive to the requirements of credible minimum deterrence.

In the end, therefore, the Project 75I contest is likely to be between the Super Scorpene and the Type 214 SSK.
The INs first of three projected SSBNsArihantcontinues to remain berthed under a shed at the Ship Building Centre (SBC) near the Naval Dockyard in Vishakhapatnam. Once its PWR goes critical by next February, and will undergo all the standard harbour and sea trials common to all nuclear-powered submarines. The vessel has already completed several trim dives alongside, an operation that requires very detailed trim calculations for the first of the class. This is a very critical operation for flooding and de-flooding the ballast tanks by the on-board pumps. SBC has all the facilities to produce external steam and power for the Arihant. With external steam and power, the SSBNs propulsion, steering gear and associated systems, electronics and generators can be set to work and tested during harbour trials. When all the systems are expected to be cleared by the Submarine Overseering Teams over the next 65 days, the full ships complement will join the boat for very detailed safety and emergency training. This will be a very critical part of the commissioning, and will be overseen by a specialist submarine-qualified Vice Admiral responsible for nuclear propulsion safety from Naval Headquarters (NHQ). After all the harbour trials are completed, the Arihants on-board PWR will go critical at low power and be gradually worked up to higher power to enable the hull to go to sea. When this happens, INS Arihant will report Underway on Nuclear Power. The next phase of trials and evaluations will include sea trials on surface at various speeds, and when the confidence of the crew complement rises, the SSBN will carry out its first shallow dive by the latter half of next year, going deeper progressively at various speeds. On return from every diving trial, several mandatory structural checks on the hull and PWR performance will be carried out by specialists, and the final deep dive to maximum operating depth will culminate in the SSBN embarking upon Phase 3 of its sea trials schedule, this involving weapons-firing trials. Only after all three phases of trials are completed will the Arihant be commissioned sometime before 2014. However, should something go wrong, the IN will require the services of a Deep Rescue Submarine Vessel (DSRV), which remains elusive despite efforts to acquire a few from either the US or Canada. Instead, it is relying on a diving support vessel with a decompression chamber, and has also contracted the US Navy to fly in a DSRV and deploy it to the site of the accident.
The DSRVs absence will also be felt by the crew complement of the K-152 Nerpa (the Seal), a Project 971A Shchuka-B (Akula-3) SSGN, which was commissioned as the INS Chakra on December 29 at Bolshoi Kamen in Russias Primorye region. Obtained on dry-lease for a period of 10 years (with an option to increase it by another five years) the K-152 Nerpa (the Seal), a Project 971A Shchuka-B (Akula-3) SSGN whose keel was laid down in 1986. The Letter of Intent for leasing the SSGN under Project India was inked on February 8, 2002 in New Delhi during the 2nd session of the IRIGC-MTC between the then Russian Deputy Prime Minister Ilya Klebanov and the then Indian Defence Minister George Fernandes. On November 24, 2002 final price negotiations for the lease began took place during Klebanovs visit to New Delhi. Rosoboronexport officials then stated that fabrication of the two SSGNs will resume after India pays the first tranche of $100 million as per the contract. The final lease contract for only the Nerpa for the time-being, valued at US$920 million, was inked in New Delhi on January 20, 2004. The Nerpa is the 15th SSGN and the second Akula-3 built under project 971 (codenamed Shchuka) and was designed by the St Petersburg-based Malachite Marine Engineering Bureau under Chief Designer Georgy Chernyshev who, after his death in 1997, was succeeded by Yuri Farafontov. While the Severnoye Machine-Building Enterprise has to date built seven Akulas, the Amursky Shipbuilding Plant has built eight. The Akulas built by the former have been named after land-based beasts of prey, while those built by the latter bear the names of fish and other marine animals. The latest version of the Akula SSGN is the Akula-3 and its dived displacement is 13,800 tonnes, full dived speed is 33 Knots, operational diving depth is 520 metres and maximum diving depth is 600 metres. The SSGN can carry up to 40 weapons ranging from supersonic anti-ship cruise missiles to torpedoes to sea mines. The Akula-3 comes with a two-stage noise supression system and all compartments are shockproof, which results in a five-fold reduction in the level of acoustic fields when compared to the Akula-1. Both the Nerpa and its sister vessel, the K-335 Gepard, are the first3+ generation nuclear-powered submarines of Russian origin that have a centralised integrated platform management system (IPMS) and a combat management system (CMS), all of which have resulted in the crew complement being reduced to only 73. The IPMS is called Molibden-1 and has been developed by the Krylov Central Research Institute, while the CMS was developed by the St Petersburg-based Aurora Research & Production Association FSUE, which has also supplied the 15-module submarine monitoring-cum-data recording system. The integrated sonar suite has been developed by Morphyspribor Central Research Institute and Akvamarin JSC, and built by FSUE Taganrog Priboy Plant. The Nerpas most visible distinguishing features are the more elongated and slightly pugged barriers (to its port and starboard) for retractable gear and a more aft-mounted compact gondola mounted on the aft vertical fin, which houses a low-frequency thin-line towed-array sonar suite.
INS Chakra is due to arrive in late January next year at Vizag, HQ of the INs eastern Naval Command, after undertaking a ferry voyage through the Western Pacific and entering the Bay of Bengal after transiting through the Malacca Straits. In January 2007, work began on modifying (at a cost of $135 million or Rs5.4 billion) the SSGN to accept on board up to 18 Novator 3M53E/3M14E multi-role cruise missiles as well as TEST-71ME and TEST-71ME-NK torpedoes (built by Russias DVIGATEL FSUE and Region State Research & Production Enterprise) that will be fired from the SSGNs six 533.4mm and four 650mm tubes. The hull will feature twin flank-array sonars for being used as a torpedo approach warning system, and a stern-mounted distinctive bulb on top of the rudder housing a low frequency thin-line towed active/passive sonar array. INS Chakras crew complement will be all-Indian. Some 300 IN personnel, comprising three sets of crews, have for the past five years been extensively trained and type-rated to man the SSGN at a specially built secure facility in the town of Sovnovy Bor near St Petersburg. The IN will be using this SSGN for the following:
·Undertaking anti-submarine patrols along the southeastern and southwestern parts of the Indian Ocean.
·Establishing a series of restricted submarine patrol sectors in far-flung areas of the Indian Ocean to allow persistent undersea warfare operations unimpeded by the operation of, or possible attack from, friendly or hostile forces in wartime; and without submerged mutual interference in peacetime.
·Perfecting the art of communicating with submerged SSGNs using VLF, UHF SATCOMS, SHF and EHF frequencies, and using maritime surveillance/ASW aircraft as mission controllers for the SSGNs.
·Exploring ways of evolving a robust and nuclear first strike-survivable two-way communications system comprising shore-based, airborne and submerged elements to ensure that the SSGNs commander receives explicit rules of engagement and strategic targeting data.
· Analysing the pros and cons of having either a decentralised C³ network for certain types of missions, or a tightly centralised network by developing command automation via network-centric warfare strategies.
· Trying to achieve submarine internet protocol connectivity and working on solutions that will deliver a reduction in time latency, increased throughput and the ability to maintain communications at speed and depth. One technology demonstrator already developed by the DRDO by still classified comprises a submarine- or air-launched recoverable tethered optical fibre (RTOF) buoyant 450mm diameter buoy which, upon reaching the surface, deploys a low-frequency acoustic projector to a preset depth, enabling reach-forward from the Fleet Commands SSGN operating authority via a built-in SATCOM antenna. A pager is then activated via SATCOM and paging and target cueing messages are sent to the submarine at a data rate of 2.4 kb/second. Consideration is also being given to the use of a swimming communications device, such as an autonomous underwater vehicle (AUV), which would surface to exchange data via SATCOM via a repeatable 32kb/second communications window, and then return to the host SSGN for download. A prototype AUV for undertaking such operations has already been developed by the DRDO.
· Use of RTOF buoys, which provide data rates of around 32kb/second while the SSGN is cruising at 8 Knots and is more than 244 metres underwater. The INs longer-term network-centric vision includes the use of distributed undersea networks, offering the submarine a network of known underwater nodes to be used to download large amounts of information, while remaining at depth. The concept calls for a field of acoustic sensors, UHF local area network-linked platforms and SATCOM buoys.
· Establishing a protocol for undertaking deep-sea crew rescue and salvage operations using the INs yet-to-be-acquired remotely operated rescue vehicles (RORV) and related launch-and-recovery system (LARS) and a fully integrated self-contained emergency life support system (ELSS) package.
However, it must be noted that the acquisition of INS Chakra will by no means give India the long-awaited third leg of the nuclear triad. Neither will the SSGN come under the tri-service Strategic Forces Command. Simply put, the Akula-3 SSGN will be armed with Club-S anti-ship/land attack cruise missiles which, along with the on-board torpedoes, will give the SSGN a formidable sea-denial capability along a 200nm arc contiguous to Indias coastline as well as in the Indian Ocean Region. Russia, which adheres to the Missile Technology Control Regime along with the NPT and START-2 treaties, is obligated to ensure that INS Chakra does not carry any nuclear weapon whatsoever. Furthermore, the SSGNs employment in wartime too will be highly restricted and its rules of engagement will have to be cleared with Moscow, thus limiting Indias operational sovereignty over the SSGN. In fact, it is due to this very reason that Navy HQ has been insisting since the early 1990s that the DRDO accord greater priority to developing indigenous SSGN solutions (for protecting the projected fleet of three deployed SSBNs) to ensure that Indias nuclear deterrent, in the long run, remains effective, enduring, diverse, flexible, and responsive to the requirements of credible minimum deterrence.
