India’s Submarine Situation: Evolving Capabilities and Opportunities

The Future of Undersea Competition Topic Week

By Vidya Sagar Reddy and Rajeswari Pillai Rajagopalan

Two events set the stage for India-China strategic competition going underwater – one is the docking of China’s submarine in Sri Lanka’s Colombo port and the other is the loss of India’s submarine INS Sindhurakshak in a major fire incident.. These and subsequent events showed that China is signalling its strategic intentions in the Indian Ocean via its submarines while the resident power is scrambling.

The claim by China that its submarines are deployed as part of anti-piracy operations in the Gulf of Aden has been refuted on the grounds of overmatching capability of these platforms and the timing when piracy is coming down.

Protection of sea lines of communication in the vast Indian Ocean region is in the interest of every state and therefore naval cooperation would be both economical and reassuring. Such an outlook is however not forthcoming from China. Rather it is undertaking unilateral actions without establishing proper communication with other navies in the region.

The submarine deployments can therefore be considered as geopolitical signalling of a rising China. First, the long range deployments showcase the capabilities of a blue water navy. The Indian and Pacific Oceans are the primary theatres of such deployments. Second, the timing of deployments showcases intent.

A Chinese submarine docking in Colombo coincided with the visit of Japan’s Prime Minister Shinzo Abe to Sri Lanka. The docking in Karachi came on the heels of India’s Prime Minister Modi’s first official visit to China. It sent warships inside the U.S. territorial waters off Alaska when President Obama was visiting.

The intent behind these strategic signals cannot be missed. China consistently opposes any partnership between the navies of India, Japan, and the U.S. given their capacity to challenge its unlawful assertions in the East and South China Seas.

India’s economic growth and influence in the international order are dependent on the reawakening of its maritime culture. Accordingly, it is taking a number of policy and investment actions in this direction.

The success of these initiatives is dependent on a peaceful and stable neighborhood along with a secure Indian Ocean region. China’s presence and intentions in this region carried out through its submarine deployments signals the contrary. It even finalized a deal to sell eight submarines to Pakistan with little regard to India’s sensitivities.

Considering these developments, India decided to augment its current underwater fleet of only 13 aging diesel-electric (SSK) submarines (nine of Soviet and four of German origin). These submarines constructed during the Cold War have already reached their replacement period. Commissioning new submarines into the force is critical at this juncture  as India’s national interests expand and threats multiply across the Indian Ocean.

India therefore initiated Project 75 and Project 75(I) to strengthen its submarine arm. The Project 75 will deliver six SSK of French Scorpene design with the last two added with indigenously developed air-independent propulsion system (SSP). There is also a provision for adding three more platforms.

The Project 75(I) is follow-on to the Project 75 to build six advanced SSP submarines fitted with vertical launch systems to fire BrahMos supersonic cruise missiles and torpedo tubes. India is also designing six nuclear powered attack submarines.

The first of Project 75, INS Kalavari, is undergoing sea trails and is expected to be commissioned by 2016. The remaining five boats will be delivered by 2020. Unfortunately, the INS Kalavari will be commissioned without its main weapon, the torpedo, since the government decided against buying them from a company under investigation.

It will be quite some time before these projects mature and the submarine arm of the Indian navy operates at its full potential. The Project 75 itself is running almost four years behind schedule. Additional Poseidon P-8I anti-submarine warfare (ASW) aircraft can be acquired to fill the gap initially and to later form a three dimensional force to counter submarine threats.

The P-8I is the Indian variant of P-8A Poseidon operated by the U.S. Navy for long range maritime reconnaissance and ASW requirements. India contracted Boeing to build eight of these aircraft for the Indian Navy. Indeed, the first platform arrived in 2013 just as the Indian Ocean’s subsurface started heating up.

Its speed, range and endurance enables India to mount rapid surveillance missions deep into the Indian Ocean. It was deployed recently for surveillance in the exclusive economic zone of Seychelles and had been pressed into action to hunt for Chinese submarines probing near the strategically located Andaman and Nicobar islands. The P-8I boasts advanced sensor and communication suites and is armed with missiles, torpedoes, and depth charges.

The P-8I is a key platform enabling interoperability with the U.S. Navy that shares India’s concerns in the Indian Ocean. Both countries have decided to upgrade their defense relationship to include submarine tracking, communication, and ASW capabilities. The next joint naval exercise will see enhanced ASW practice.

India should also enhance its submarine interoperability with Vietnam, Indonesia, and Australia while  extending the scope of partnership beyond the Indian Ocean. Australia recently finalized an agreement with the French firm DCNS to deliver 12 submarines to replace its aging Collins class submarines. Vietnam and Indonesia are set to acquire six and at least two Russian Kilo submarines respectively.

India has already trained Vietnam’s submariners and is in talks with Russia to establish Kilo class submarine maintenance and modernization infrastructure in the country. South East Asian countries are weary of China’s intentions and are visibly frustrated with its use of force in the South China Sea (SCS). Vietnam is on the frontline while Indonesia is closely monitoring the situation but is also perturbed.

China’s turning out of   large number of submarines each year and the associated basing facilities in Hainan and their proximity to SCS islands easily overwhelms other claimants and concerned parties in and beyond the region.

It is absolutely essential to exchange information for forming a joint operational picture of the undersea domain of the Indo-Pacific. Submarine interoperability between the concerned parties is critical to deter and defeat fast emerging threats. India should take advantage of its diplomatic and material capabilities to realize these objectives for the purpose of maintaining peace and stability in the region.

Deception and the Backfire Bomber: Part One

The following article is part of our cross-posting series with Information Dissemination’s Jon Solomon. It is republished here with the author’s permission. It can be read in its original form here.

By Jon Solomon

Last winter’s Naval War College Review contained a must-read article on the Soviet Navy’s doctrine from the 1980s for employing its TU-22M Backfire series of bombers against U.S. Navy carrier groups. In “Kamikazes: the Soviet Legacy,” former Soviet Navy officer Maksim Y. Tokarev reveals many details regarding Backfire capabilities and tactics that, to my knowledge at least, have not been previously disclosed within English-language open sources.

As part of my 2011 master’s thesis, I conducted a case study examination of how the U.S. Navy used Electronic Warfare (EW) and tactical deception to counter Soviet long-range maritime strike capabilities such as Backfire during the Cold War. I found that while a considerable amount of information is now publicly (though not necessarily widely) known about the two sides’ tactics, technologies, and real-world operational experiences from the late 1950s through mid-1970s, relatively few details regarding the competition’s late-1970s through early-1990s peak have been declassified by the U.S. or Russian governments. Tokarev’s article sheds a remarkable amount of light on the latter period from the Russian perspective. In doing so, he also underlines timeless maritime targeting challenges that technology can partially ameliorate but never fully eliminate. He additionally paints an intriguing picture of how an advanced attacker might use tactical deception in an attempt to score a lopsided win in a battle at sea. In my posts this week, I will point out the most fascinating of the new details provided by Tokarev and then examine their historical significance as well as contemporary implications.

What Kind of Reconnaissance Support did Backfire Need?

One of the key historical questions regarding Backfire involves the reconnaissance support the bombers’ crews needed to effectively employ their missiles. The earlier TU-16 Badger series of Soviet maritime bombers depended upon targeting cues provided by scout aircraft. These so-called ‘pathfinders’ penetrated an enemy’s battleforce ahead of a raid in order to locate and positively identify aircraft carriers or other high-priority target ships. This was necessary because a standoff bomber like Badger simply could not tell whether a large contact held by its onboard radar was an aircraft carrier, a surface combatant or other ship configured to simulate a carrier, an artificial decoy, or a large and perhaps neutral-flagged merchant vessel. Even if a surface contact of interest made ‘telltale’ radio frequency emissions, the vessel’s type could not be determined with high confidence because of the possibility that the emissions were deceptive. Visual-range verification of contacts’ types (if not identities) was consequently a prerequisite for the Badgers to be able to aim their missiles with confidence. Yet, because the Soviet pathfinder aircraft necessarily had to expose themselves to the entirety of a battle force’s layered defenses in order to do their jobs, they represented single-points-of-failure that could easily doom a raid if neutralized before they located, classified, and identified desired targets.

In the mid-1970s, the Soviets began launching Radar Ocean Reconnaissance and Electronic intelligence Ocean Reconnaissance Satellites (RORSAT and EORSAT) into low earth orbit. RORSAT and EORSAT were primarily intended to expand the maritime areas covered by the Soviet Ocean Surveillance System (SOSS), a networked ‘system of systems’ that fused data from a wide variety of remote sensors to locate, identify, track, and target U.S. Navy forces at sea. In theory, Soviet standoff bombers might not have needed the support of pathfinder scouts if SOSS operators were able to provide a raid with high confidence, targeting-quality tactical pictures derived from RORSAT, EORSAT, and perhaps other remote sensor sources.

Backfire made its Soviet Naval Air Force (SNAF) debut in 1976. Unlike the subsonic Badger, Backfire could make its final approach to its firing position—and then its subsequent escape attempt—at supersonic speed. The SNAF’s Backfire-C variant, which reached Initial Operational Capability in 1981, carried enough fuel to make an indirect approach against a targeted naval force operating well beyond 2000 nautical miles from the Soviet coast. Defending against a Backfire raid was therefore an order of magnitude more complicated than defending against a Badger raid. The tactical dilemma facing a U.S. Navy battleforce would have been further exacerbated—potentially decisively—if a Backfire raid received its targeting data directly from SOSS instead of from pathfinders. Some later Backfire-Cs were even equipped with a communication system that allowed them to download RORSATs’ and EORSATs’ tactical pictures as those satellites passed overhead.

From a purely technical perspective, though, it seemed quite unlikely Backfire could completely do away with reliance upon pathfinders or other visual-range scouts. As I detailed in my thesis, RORSAT suffered from the same contact classification challenges that inherently plague any radar. In fact, RORSAT’s shortcomings were even worse: its sensitivity was apparently so poor that it could only detect large ships, and even then not reliably when the area it was searching contained inclement weather. EORSAT was completely dependent upon ships complacently radiating telltale radiofrequency emissions, and as a result could not compensate for RORSAT. Lastly, as neither RORSAT nor EORSAT could report their data in ‘real time,’ their contact pictures generally suffered from tactically-significant lateness. Nevertheless, other than anecdotes from U.S. Navy veterans of the 1980s who directly observed SNAF operations when their carrier groups steamed into the “Bear’s Den,” and beyond some open source scholarly interpretations of Soviet doctrine dating to the early 1990s, until Tokarev there has been virtually no authoritatively-sourced evidence available to the public confirming or refuting Backfire’s dependence upon pathfinders.

On that note, Tokarev first relates that SNAF bomber forces:

“…always tried to use reconnaissance and targeting data provided by air assets, which was also most desired by their own command structure. Targeting data on the current position of the carrier sent by surface ships performing “direct tracking” (a ship, typically a destroyer or frigate, sailing within sight of the carrier formation to send targeting data to attack assets—what the Americans called a “tattletale”), were a secondary and less preferable source. No great trust was placed in reports from other sources (naval radio reconnaissance, satellites, etc.). Lieutenant General Sokerin, once an operational officer on the Northern Fleet NAF staff, always asked the fleet staff’s admirals just to assign him a target, not to define the time of the attack force’s departure; that could depend on many factors, such as the reliability of targeting data or the weather, that generate little attention in nonaviation naval staff work.”(Tokarev, Pg. 73)

He later amplifies this, noting that Backfire crews

“…had the targeting data that had been available at the moment of takeoff and kept the receivers of the targeting apparatus ready to get detailed targeting, either from the air reconnaissance by voice radio or from surface ships or submarines. The latter targeting came by high-frequency (HF) radio, a channel known as KTS Chayka (the Seagull short-message targeting communication system) that was usually filled with targeting data from the MRSC Uspekh (the Success maritime reconnaissance targeting system), built around the efforts of Tu-95RC reconnaissance planes. The Legenda (Legend) satellite targeting system receiver was turned on also, though not all planes had this device.” (Tokarev, Pg. 74)

These statements tell us two things. First, while Backfires could use direct satellite-based cueing, they relied heavily upon—and in fact placed greater trust in—targeting provided by scout aircraft. Second, a Backfire (or any Soviet maritime bomber) sortie depended upon raid planners being told approximately where a U.S. or NATO naval group was operating. If SOSS or any other surveillance or reconnaissance capabilities supporting this general cueing was disrupted or deceived, a raid might be dispatched to the wrong location, might be wasted against a decoy group, might be exposed to an ambush, might be held back until too late, or might never be launched at all.

We must keep in mind that launching a SNAF raid was no small undertaking. Per Tokarev, an entire air division—up to a hundred bombers—might be hurled against a single carrier’s battle group. Furthermore, doctrine called for the Soviet Northern and Pacific Fleets to be equipped with three air divisions each in order to counter multi-carrier battle groups. Tokarev also mentions that the bomber attrition rate for a single raid was expected to be as high as 50% regardless of whether or not the objective U.S. or NATO warships were successfully struck (Tokarev, Pg. 73, 78). With a finite number of bombers, missiles, and trained crews, it is reasonable to think Soviet commanders would have been somewhat hesitant to dispatch such irreplaceable forces into battle unless they had some degree of confidence in their situational picture’s accuracy; the operational-strategic penalties that would be incurred if they ‘got it wrong’ simply seem too high for this not to have been the case. Accordingly, it will be extremely interesting to someday learn the criteria that had to be satisfied for SNAF commanders to order a raid.  

In part two of the series, just how effective was U.S. Navy counter-targeting?

Members’ Roundup: May 2016 Part One

By Sam Cohen

Welcome to part one of the May 2016 members’ roundup. Over the past two weeks CIMSEC members have examined several international maritime security issues, including the complexities associated with improving U.S. missile defense, the continued modernization of Chinese missile forces, the North Korean nuclear threat, China’s response to U.S. laser based weapons, and finally, defense spending concerns within the NATO alliance.

Beginning the roundup at the Center for Strategic and Budgetary Assessments, Bryan Clark with CSBA colleague Mark Gunzinger provide a comprehensive report discussing the necessity for the U.S. to rebalance and restructure the military’s air and missile defense systems. The report explains that the DoD’s emphasis on long-range surface-to-air interceptors used to defeat a small salvo of anti-ship cruise missiles or a handful of ballistic missiles launched by rogue states have failed to provide the capacity to defend theater forces against large salvos of ballistic missiles, cruise missiles, and other precision-guided munitions (PGMs). Mr. Clark highlights that the layered missile defense approach favored by U.S. forces, focused on countering incoming threats as far away as possible, lacks the resources to sustain operations against multiple strikes – meaning U.S. defenses could become quickly exhausted in notional conflict where missile threats are frequent and continuous.

Harry Kazianis, for The National Interest, discusses the Chinese DF-26 ballistic missile, noting how analyses of the capabilities and regional implications of the anti-ship variant were not adequately included in the Pentagon’s annual China military report. Mr. Kazianis highlights that the 2500-mile range of the missile should be a serious concern for regional U.S. surface combatants, particularly if combined with the more reliable DF-21Ds and other anti-ship cruise missiles launched from air, land or maritime platforms as part of a large saturation strike. He explains how this capability may allow for China to develop an extremely effective anti-access strategy beyond the first-island chain, thereby severely restricting U.S. ability to conduct operations uncontested near or in support of its regional allies.

Ankit Panda, for The Diplomat, provides an analysis on an upcoming trilateral missile defense exercise being conducted by the U.S., Japan and South Korea. All three navies will participate in the exercise using Aegis-equipped guided missile cruisers, focusing on a response to a notional ballistic missile attack from North Korea. Mr. Panda explains that although recent Japanese-South Korean bilateral relations have been characterized as difficult, the increasingly dangerous North Korean security threat combined with Washington acting as a mediator and leader in trilateral operations has contributed to a steady improvement in cooperation between Seoul and Tokyo.

In a second article at The Diplomat, Mr. Panda examines the development of Pyongyang’s nuclear strategy by focusing on Kim Jong-un’s latest iteration of the country’s nuclear use policies at the 7th Congress of the Workers’ Party of Korea. The article suggests that outlining a concrete North Korean nuclear strategy is highly problematic considering several unknown strategic variables, including Pyongyang’s conception of sovereignty violation, positions on first use and the role of second or first strike capabilities surrounding regime security objectives.

To conclude the roundup, Kyle Mizokami for Popular Mechanics discusses the deployment of the Norwegian-designed Naval Strike Missile to the USS Freedom Littoral Combat Ship. The weapon system will provide the small ship with an increased surface-to-surface combat capacity while additional deployments of the missile to other vessels are likely to follow – supporting the U.S. Navy’s interest in implementing the distributed lethality concept across the fleet.

In a second article at Popular Mechanics, Mr. Mizokami describes the development of smoke screen technologies by the Chinese military’s Chemical Corps., primarily to be used as shields against increasingly capable U.S. laser systems, such as the already active laser on the USS Ponce in addition to planned lasers on gunships, fighters, and surface ships.
