CHAPTER 16

THE SUBMARINE ARM

DEVELOPMENTS UNTIL 1965

The Navy's very first plan formulated after Independence in 1947 proposed to the Government the acquisition of four submarines. The plan did not specify in which year of the plan the submarines should be acquired. This was because of uncertainty in the source of supply and the difficulties anticipated in starting to operate submarines.

In 1948, due to budgetary constraints, the Navy was asked to recast its requirements. The Navy's 10 year plan 1948 - 1958 gave lesser priority to the Submarine Arm because it could not be created by 1958. In 1951, since large scale naval expansion could not be afforded, the Navy proposed a ship replacement programme instead of a ship acquisition programme. Submarines found no mention in this plan.

By 1956, Pakistan had joined CENTO and SEATO and was going to be given extensive naval assistance by America and Britain. The Navy had to propose the acquisition of ships to match Pakistan's acquisitions. No mention was made of submarines.

During all these years, there had been no progress on the acquisition of submarines. There were several weighty reasons:

However, the Navy kept a close watch on the design and development of post war submarines. France had developed the Daphne class. Holland had developed the Dolphin class. Britain had first developed the Porpoise class which had evolved into the Oberon class. The British Navy had increased the submerged endurance of some of its earlier World War II submarines by cutting the hull in two and inserting a midships section to provide an additional propulsion battery compartment. The American Navy had improved their conventional submarines by giving them "Greater Underwater Propulsion Power", which came to be known as the GUPPY conversion.

The Navy also kept a watch on the development of the Submarine Arms by the Commonwealth Navies. Both the Canadian and Australian Navies had taken British manned A and T class submarines on loan in which their personnel received on job training under British submariners. Both Canada and Australia were awaiting the finalising of the Oberon design before purchasing them.

By 1956, the feed back from the annual Commonwealth JET exercises indicated that the arrangements for participating Navies to share anti submarine exercise time with available British submarines were becoming inadequate for our ships. Defence Minister KrKrishna Menon wrote to the First Sea Lord, Admiral Mountbatten in May 1957 for "acquiring a target submarine service comprising the oldest and cheapest submarines, since it was not envisaged that India would need to employ them in war". (Roy Choudhary Page 37)

Because of the British Navy's extended commitments, reduced strength, procedural difficulties in loaning British naval personnel etc, the loan of a training submarine did not find favour. The Navy then accepted the British Navy's suggestion for providing India with increased anti submarine exercise time in Indian waters.

In 1958, the eight new British frigates of the naval replacement plan started arriving in India and the second hand British aircraft carrier had been purchased. The Navy re-started its case for a Submarine Arm.

In his book "Indian Navy's Submarine Arm," Admiral Chatterji states: (Page 36)

The Navy refined its line of argument. It impressed on the Government that every Navy worth its name had to have submarines. It took several years to train an officer in the operation of a submarine and give him sufficient experience to ensure that he would be competent to assume command of a submarine. The Navy urged that the Government accept the creation of the Submarine Arm in principle and allow the Navy to depute a few officers to Britain for training in submarines.

Early in 1962, the Government agreed to the deputation of personnel to Britain. The training of junior officers was accepted on the premise that intimate knowledge of submarines would help to increase the efficiency of our anti submarine ships. Since submarines were still viewed as "offensive" vessels, the Government made it clear that the approval to depute officers for submarine training did not in any way commit the Government to the acquisition of submarines.

Utilisation of British Trained Personnel Pending the Acquisition of Submarines from Russia

To ensure that the batches returning from Britain did not forget what they had learnt, arrangements were made for officers to be attached to British submarines during the JET exercise of 1964.

Approval to Commence Negotiations for Acquiring Submarines

After the military reverses in the border war with China in October 1962, a major defence review was initiated to remedy the inadequacies. This gave the Navy the opportunity to resubmit its case for the acquisition of submarines. In addition to the arguments used earlier, it was emphasised that China possessed submarines, some of which had sufficient range to operate in the Bay of Bengal. The Navy therefore needed to acquire submarines, not only for the earlier reasons, but also for employment in the Hunter-Killer role against Chinese submarines.

The new proposal put up in November 1962 asked for three submarines. The justification given was that to keep one submarine continuously on patrol in an area about 1500 miles from India, such as the Malacca Straits, three submarines would be required: one would be undergoing repairs or refit or resting the crew, the second in transit to and from the patrol area and the third actually on patrol.

Vice Admiral BS Soman was the Chief of the Naval Staff in 1963. Writing in the naval magazine Quarterdeck 1997, he recalled:

During 1963 and 1964, in the expectation of assistance from Britain and America, there was considerable discussion to crystallise the requirements for what eventually became the 1964-1969 Defence Plan. As regards submarines, the Navy had four options before it:

In view of the Navy's lack of familiarity with Russian naval hardware, the Navy recommended the acquisition of three Porpoise class submarines from Britain. Government accepted the Navy's recommendations in principle. Negotiations were started with the British Government for the acquisition of one second hand Porpoise class submarine to start with.

Discussions with Britain in 1963

In 1963, the British were experiencing economic difficulties and were considering reduction in their naval forces. The British Navy was not willing to spare one of their own Porpoise class submarines. However, British shipbuilders were willing and eager to build an Oberon class submarine for India. The Navy was agreeable to buy one new Oberon but sought deferred credit terms to cover the cost of the submarine, which at 1963 prices was working out to about Rs five crores - three crores for the submarine and two crores for the infrastructure. The British were unwilling to extend soft credit and India could not spare the foreign exchange.

By early 1964, the 1964-1969 Defence Plan had taken shape and the requirements therein had been indicated to America, Britain and Russia in preparation for the visit to these countries of delegations led by the Defence Minister. Commodore (later Admiral) SM Nanda was the Deputy Chief of the Naval Staff at that time and represented the Navy in all three delegations.

Discussions in America-May 1964.

Mr PVR Rao was the Defence Secretary from after the Chinese war in 1962 till after the Pakistan war of 1965 and accompanied the Defence Minister's delegation to America. He recalls:

American records are not yet available which could throw light on precisely why America declined India's request for submarines. The reasoning of "traditional supplier" appears odd because in that very same year 1964, Pakistan was given the submarine GHAZI on loan for a period of three years to start with. It is more likely that Congress would not have agreed to loan submarines to India because India was not a CENTO/SEATO ally of America, whereas Pakistan was. The American Administration may also have reconciled themselves to the Indian Navy turning to Russia as the Indian Air Force had done, in case the West was unable to meet its needs.

On the eve of the Defence Minister's delegation to Russia in September 1964, the position was:

Under the circumstances, the delegation's task was to explore the availability of the Navy's requirements from Russia and the financial implications of doing so.

Discussions in Russia - September 1964

In Russia, the response to the Navy's requirements was positive. The Russians offered four of their new F class submarines, a submarine depot ship and other vessels.

Admiral Nanda recalls:

Mr RD Pradhan, IAS, was the Private Secretary of Defence Minister YB Chavan from 1962 to 1965. He accompanied the Defence Minister in 1964. In his memoirs "Debacle to Revival", he states: (Pages 229 et seq).

Discussions in Britain-November 1964

Admiral Nanda recalls:

Mr PVR Rao, the Defence Secretary, accompanied Mr Chavan's delegation to Britain. He recalls:

To avoid a distruption in the naval relationship, the British agreed to reconsider whether they could find ways and means to give India deferred credit for building a new Oberon class submarine in a British shipyard.

Developments in Early 1965

Indonesian Bellicosity

After the conference in Bandung in Indonesia in 1955, when the principles of Panchsheel were formally accepted, relations between India and Indonesia had steadily deteriorated. The predominant Communist Party of Indonesia had close links with Communist China and the Soviet Union. Between 1958 and 1965, the Soviet Union gave Indonesia a substantial naval fleet. Indonesia wanted to rename the Indian Ocean as the Indonesian Ocean and intrusions were observed in the Nicobar Islands, the nearest of which was only 90 nautical miles from the northern tip of Sumatra.

Mr K Subrahmanyam was Deputy Secretary Budget and Planning in the Ministry of Defence in 1964 and 1965. He recalls:

The Navy's Hesitance to Switch Over to Russian Acquisitions

There is no doubt that Naval Headquarters had grave reservations about going in for Russian acquisitions. Indeed, the Navy appears to have been almost apologetic. Admiral Kohli, who was the Deputy Chief of the Naval Staff in 1965, states in his book:

In 1965, the agreement was signed for the acquisition of Russian ships and submarines. Admiral Kohli, then Deputy Chief of the Naval Staff, headed the Naval team of this delegation. In his book, he states :

Admiral Mountbatten, visited the National Defence College after he retired as the British Chief of the Defence Staff. He deplored "The short sightedness of the British Government who, by declining a deferred credit of a measly five million pounds for building an Oberon class submarine, forced the Indian Navy to acquire its requirements from Russia, thereby limiting the British warship industry's market to meeting the needs only of the Leander Frigate Project."

DEVELOPMENTS 1966 TO 1975

Selection of Crew and Pre Deputation Russian Language Training

Captain MN Samant recalls:

All personnel selected to undergo training in Russia were given three months of Russian language training in Bombay.

Submarine Training in Russia

Commodore KS Subra Manian recalls:

Vice Admiral (then Lt) RN Ganesh had joined the Submarine Arm after training in Britain had ceased. He was later to be the first Commanding Officer of the nuclear propelled submarine CHAKRA. His recollections of training in Russia were, in some respects, different from those who had earlier been trained in Britain:

Rear Admiral (then Lt) SC Anand underwent his initial submarine training in Russia. He recalls:

Submarine Infrastructure Facilities

The 1965 agreement with Russia not only covered the delivery of ships and submarines, but also the creation of a modern Dockyard at Visakhapatnam, along with a submarine base and training school.

The basic infrastructure required for the Submarine Arm was a submarine base, a submarine training establishment, submarine maintenance and repair workshops, facilities to charge the submarine propulsion batteries and the high pressure air bottles and facilities for blowing the ballast tanks and preparing submarine torpedoes.

Since the new Dockyard would take several years to come up, interim arrangements were made for the Base Repair Workshop in Visakhapatnam to be expanded.

The Induction of the Submarines

After commissioning, each submarine did a three month combat work up in the Baltic before departing for India. Since the Suez Canal was closed, the maiden voyages were around the Cape of Good Hope. The first two submarines were escorted by Indian naval ships, the latter two came on their own. The first four submarines arrived between July 1968 and May 1970 and were based in Visakhapatnam .

After arrival, the submarines:

In 1971, an agreement was signed for four improved Russian submarines of the same class. The improvements were the result of experience gained by us in operating the submarines in Indian tropical conditions:

The 1971 Indo Pakistan War

During the 1971 war KURSURA and KARANJ operated in the Arabian Sea. KHANDERI operated in the Boy of Bengal. Their activities have been described in the chapters on the 1971 war.

KALVARI remained in Visakhapatnam to continue training of fresh inductees for the next lot of four submarines.

Basing of Submarines in Bombay

After the 1971 war, it was decided to base the four new submarines in Bombay and create the minimum essential support, maintenance and repair facilities.

These four submarines arrived in Bombay between January 1974 and May 1975. Until their shore facilities were set up, they were supported by the submarine depot ship AMBA, which had been moved from Visakhapatnam to Bombay.

After arrival, these submarines participated in anti submarine exercises, evaluations and operational patrols as the earlier submarines had done. They were saved however from having to expend precious motoring hours in transits between the East and West coasts, which had been unavoidable for the earlier four submarines based in Visakhapatnam.

PERSONNEL ASPECTS

From the outset, the tight delivery schedule of the submarines created problems. By 1969, personnel shortages began to cause concern. Several measures were taken to remedy these shortages.

Reducing the Rejection Rate

Analysis indicated that a major cause of the shortage in intake was the large number of rejects in the psychological tests and the general lack of confidence in the procedures for selection. It was decided:

Monetary Incentives

To make service in the Submarine Cadre attractive, special benefits were sanctioned. These were Submarine Allowance, Submarine Pay, Submarine Rations, Special Submarine Clothing and Hardlying Money at full rates.

Special Rations

Submarine Depot Ship - AMBA

The Submarine Depot Ship AMBA had commissioned in 1968 and had been based in Visakhapatnam. Between 1969 and 1971, AMBA supported the submarines operating on the West Coast. In the 1971 war, AMBA was deployed to patrol off the Lakshadweep Islands, across the sea lane between East and West Pakistan.

With the arrival of VELA at Bombay in early 74, AMBA's base was changed from Visakhapatnam to Bombay. From early 1974 onwards, AMBA was commanded by a CO who had commissioned a submarine in Russia. He was well aware of what submariners expected from their depot ship. In the following months, AMBA ably fulfilled her designed role as a Depot Ship:

Submarine Rescue Vessel - NISTAR

The submarine Rescue Vessel NISTAR commissioned in 1971 and was based at Visakhapatnam. She conducted the diving operation on the Pakistan Navy submarine GHAZI, which sank outside Visakhapatnam harbour in December 1971.

From 1972 onwards, NISTAR helped train divers to meet the Navy's urgent need for Deep Divers and Clearance Divers.

Submarine Training School - SATAVAHANA

The Submarine Training School, which formed part of the Integrated Type Training Establishment for the Russian acquisitions, was commissioned as INS SATAVAHANA in December 1974.

Six Yearly Refits of Submarines

The delays in the completion of the Naval Dockyard at Visakhapatnam began to delay the commencement of six-yearly refits of submarines. To ensure that the safety of submarines was not prejudiced, detailed discussions were held with the Russian side. It was decided that the refit of the first submarine KALVARI would be carried out in Russia and that of the second submarine KHANDERI in Visakhapatnam. Dockyard personnel proceeded to Russia to acquire first hand experience of how these repairs were done.

Indigenous Submarine Batteries

In 1973, Standard Batteries of Bombay went into collaboration with Tudor, the Swedish battery manufacturers, to produce submarine batteries indigenously. After the initial teething troubles had been overcome, these batteries proved far superior in Indian conditions than the performance of the imported batteries.

Other Activities

In 1975:

DEVELOPMENTS AFTER 1975

Six-Yearly Refits of Submarines

KALVARI returned to Visakhapatnam in 1976 with no defects. Her guarantee specialists returned to Russia earlier than scheduled. It provided a benchmark of a high quality refit to the personnel in Visakhapatnam who had commenced the six yearly repairs of the second submarine KHANDERI in mid 1976.

The actual experience with KHANDERI was beset with delays due to lack of expertise, shortage of spares and the low productivity of the Dockyard. Progressively, as expertise built up and the Dockyard facilities developed, it became possible to become self sufficient for submarine refits. Spares however always remained a problem.

In subsequent years, six yearly refits were carried out both in Visakhapatnam and in Russia. This helped to mitigate the problems of bunching which was a result of four submarine being acquired in 1968-1969 and another four in 1973-1974.

Indigenous Submarine Construction

In 1981, almost fourteen years after the initial dialogue with HDW of Germany, Kockums of Sweden, Vickers of Britain, DCN of France and Nevesbu of Holland, a contract was signed with HDW of Germany for four submarines - two to be built in Germany and two in Mazagon Docks, Bombay. These four submarines, called SSKs, entered service between 1986 and 1994.

Acquisition of Improved Russian Submarines

Between 1986 and 1990, eight improved Russian submarines of the Kilo class were acquired. These submarines were quieter, had better sonar and used indigenously produced submarine propulsion batteries.

Nuclear Propulsion

Lease of Russian Nuclear Submarine

In 1988, a nuclear submarine was leased from the Russian Navy. It was commanded and manned by Indian naval personnel and commissioned as CHAKRA. She was returned to Russia in 1991.

During this three year lease period, the Navy was able to better understand:

Very Low Frequency Communications with Submarines at Sea

Whereas a submarine on the surface can transmit and receive wireless messages just like a ship can, submerged submarines can only receive wireless messages on Very Low Frequency (VLF). VLF transmitters require huge antennae suspended high above the ground.

The initial discussions were solely with the Russian side, from whom the submarines had been acquired. Inquiries with western manufacturers indicated that better technology might be available from America. Parallel discussions were therefore pursued, both with Russia and with America.

Between 1979 and 1984, modalities were worked out for American company in collaboration with an Indian company to assume responsibility for the detailed design, manufacture, site installation and commissioning of the VLF transmitting station.

During the same period, the Defence Research and Development Organisation designed the antennae to be fitted in the submarine for receiving VLF transmissions.

Installation of the VLF Transmitter commenced in 1987. Trials completed in 1989. On 20 Oct 90, the VLF Transmitting Station was commissioned as INS KATTABOMAN.

RETROSPECT

If one corelates the justifications for setting up the Submarine Arm with events as they transpired during the decade 1965-1975, it becomes evident, as is usually the case with most new acquisitions, that either it takes considerable time for expectations to become reality or that expectations mutate as experience is gained. The following examples are illustrative.

Examples of Expectations that Did Not Materialise

The first expectation was that acquiring submarines would enhance the anti submarine effectiveness of our surface ships. Commodore KS Subra Manian recalls:

The second expectation was that in a war, submarines could be used offensively. The section on submarine operations during the 1971 Indo-Pakistan war clearly indicates why this expectatiation did not translate into reality.

Examples of Utilisation Not Foreseen But Which Proved Invaluable

If submarines had not been available, it would not have been possible to undertake the following evaluations in the unusual hydrological conditions which prevail in Indian waters:

Under Utilisation of Submarine Depot Ship AMBA

In hindsight, it is interesting to note that some of the facilities which the submarine depot ship had could not be utilised. These were stated to be:

One reason for the under-utilisation of the submarine depot ship was the difference in perceptions. The Submarine Arm felt that the submarine depot ship should be exclusively earmarked for the submarines. The Navy felt that the depot ship's capabilities could be better utilised in general fleet ship functions, in addition to providing technical support to the submarines. These perceptions never reconciled. AMBA did however fully justify its role when from 1974 onwards it extended support to the VELA class submarines in Bombay.

In retrospect, the growth of the Navy's Submarine Arm was phenomenal. Very few navies have acquired four submarines in three years after the start of a Submarine Arm. Even fewer navies have successfully built their own submarines in twenty five years after starting a Submarine Arm.

In the short span of 30 years from the time that submarine training first started in Britain in 1962, till the time CHAKRA was returned to Russia in 1991, the Navy saw the submarine fleet grow to 20 submarines - 16 Russian conventional ocean going submarines, 4 German conventional Hunter Killer SSK submarines (of which two were under construction in India).

This unprecedented achievement was only possible because of:
