On March 29 a chapter of Indian Navy’s flying prowess as part of its
aviation arm, took a farewell bow as eight Tu-142MR (Tuploev) planes of
the Indian Naval Air Squadron (INAS) 312 were decommissioned after
proudly serving the Indian Navy for 29 long years. A poignant ceremonial
fly past was held at INS Rajali, India’s premiere Naval Air Station in
Arakkonam, as Tu-142s made their last flights.
At the expense of
repetition, it needs reiteration that submarines form a vital part in
the inventory of any large Navy’s three-dimensional ‘Order of Battle’
(ORBAT).
A conventional diesel powered submarine has less
visibility in peace, because it is essentially a vehicle for war
constantly working up when not in refit or self maintenance period
(SMP), and executing arduous ‘war patrols’ fully armed with lethal
torpedoes and missiles loaded in congested spaces with long periods
under water.
In peace time submarines contribute to intelligence
operations, and train the surface fleet and anti submarine planes and
helicopters in Anti Submarine Warfare (ASW) in exercises called CASEXES.
Nuclear
powered submarines with potent missiles and torpedoes have endurance
under water and are called SSNs as they are not easy to detect. The
nuclear powered and armed with nuclear tipped under water launched long
range missiles are vehicles for nuclear deterrence called SSBNs.
Submarines with special under water kill torpedoes are also dubbed as
Submerged Submarine Killers (SSKs).
India needs all these types
in numbers as India has two partnering nuclear nations, Pakistan and
China as its neighbors with increasing submarine ORBATs. Submarines pose
threats in being. China also has ambitions to base ships and submarines
in the Indian Ocean Region (IOR) in the long term with captive bases.
A
submariner’s motto, is to ‘run deep and run silent’, and the underwater
service is dubbed as the ‘silent service’. Submarines are referred to
as manmade stealthy ‘sea-monsters’, requiring quality and well trained
manpower, and the Indian Navy’s submarines are based on both coasts with
a submarine training school INS Satavahna at Vishakapatnam and a new
submarine base Varsha is coming up South of it on the East coast near
Rombili.
This will decongest Vishakapatnam where nuclear
submarines are based and constructed at the Ship Building Centre(SBC) in
the Eastern Naval Command.
The Indian Navy’s submarine strength
had risen to a healthy twenty modern boats in early 1990s with seven
Foxtrots, nine new Kilos, two new Shishumars and nuclear powered INS
Chakra which was completing its four year lease (1987-91) from the
Soviet Union with highly trained crews.
But steadily the ORBAT
has been falling with no orders till 2006, and is now down to fourteen
conventional and two nuclear submarines which include the nuclear Akula
INS Chakra on lease since 2012 from Russia and the nuclear powered home-
made INS Arihant with 750-km K-15/B -05 nuclear tipped missiles.
The
second of three home-made larger nuclear submarine Arighat with an
additional plug to accommodate longer ranged 2000km K-4 underwater
launched nuclear missiles is in advanced stage of construction, and
Russian media reports another Akula is likely to be transferred on
lease.
The current Navy’s detailed ORBAT stands at the aging nine
imported Russian 2,400 ton Kilos with Klub missiles and CET-65
torpedoes. Unfortunately, INS Sindhurakshak was lost on 14th August 2013
with eighteen lives in an internal explosion in the Naval Dockyard
Mumbai while she was preparing for a War Patrol.
The Indian Navy
does not have long refit facilities for its 877 EKM Kilos and has to
send them to Russia for the two year long refits where a submarine is
stripped and upgraded at high cost.
INS Sindhukesari arrived at
the Zvezdochka Shipyard in Severodvinsk near where INS Vikramaditya was
refitted in mid June this year aboard the dock ship Rolldock Star, and
it is reported INS Sindhuraj is slated for refit later. INS Sindhukriti
was refitted and upgraded with Klub missiles at the Hindustan Shipyard
Ltd (HSL) but the refit took a decade as support in India and expertise
was lacking. The exercise to refit 877EKM Kilos in India was given up.
The
Navy’s ORBAT also includes four 1,800-tonne SUT-B torpedo firing
HDW-1500 Shishumars, of which two were imported from Germany and two INS
Shalki (S-46) and Shankul(S-47) were built in India at Mazagon Dock
Shipbuilders Ltd (MDSL) Mumbai in 1992 and 1994, respectively, and are
being fitted out with Harpoon missiles.
The first of six
2,000-tonne Scorpene submarine INS Kalvari built by MDSL and DCNS was
commissioned on December 14, 2017 by Prime Minister Narendra Modi and is
fitted with the SUBTICs command and control and SM-39 Exocet missiles
but it’s torpedo has not been selected. The Shishumar’s SUT-B torpedo
was used in the trials.
However, it is of concern that eleven of
the current fourteen conventional boats are over twenty-five years old.
Their quality for war patrols has perforce begun to deteriorate, and
nearly a third remain in refit or SMP.
In recent times Navies are
fitting out plugs of autonomous Air Independent Propulsion (AIP)
systems or Sterling Engines, to remain under water with internal
breathing for longer durations to avoid coming up to charge batteries
and evade detection.
Indian Navy plans to enter the AIP regime
with its next set of submarines called Project 75 (India) for which and
an RFI for six submarines has been issued and replies are expected by
October 16. DRDO’s Naval Metallurgical Research Laboratory (NMRL) at
Ambarnath near Mumbai and Larsen and Toubro (L&T) are currently
holding trials for an AIP system named Marin with foreign help as AIP is
inescapable for modern submarines.
The Defence Acquisition
Council (DAC) has approved eight SSNs to be built in India under a
strategic partnership but progress for even the RFI has been slow,
though it is reported design work is in progress by Navy-DRDO and
L&T in a facility near Gurgaon.
This then is a current
submarine status report and there is a genuine lament that the Indian
Navy’s submarine strength is at its lowest numbers and the reasons for
the decline is because India’s inherent security postures since
Independence have been reactive to threats, and not properly planned,
and funds remain constrained, as there is no combined tri service
appreciation of needs.
Government has set up a Defence Planning
Committee (DPC) with the three Chiefs under National Security Adviser
(NSA) Mr AK Doval to follow up.
Some essential acquisitions in
the past have also been cancelled due to corruption charges, and India’s
submarine plans have been the victims of these policies. The Government
approved a 30-year two line twenty-four submarines plan as early as
1999 but it could only order one line of the six Scorpene submarines in
2006 called Project 75, with option for six more.
Fortunately,
Indian Navy realised the need for nuclear powered submarines in the
1980s as inescapable vessels as they can remain underwater as long as
supplies allow.
DRDO set up the Project Advanced Technological
Vessel (ATV) now called Aakanshka under naval command, which has
delivered INS Arihant as a Made in India submarine for nuclear
deterrence in a Public Private Partnership (PPP) with Larsen &
Toubro Ltd (L&T) which was provided a full shed on lease at SBC.
Navy
also set up a Very Low Frequency (VLF) communication facility in South
India INS Kattaboman for communications with SSNs and SSBNs which carry
the French Neriedes under water antennae, whose role is deterrence and
indicates the importance of nuclear submarines in a nation’s ORBAT
especially for a nation like India which has two nuclear neighbours
Pakistan and China.
The PLA (Navy) has over ten nuclear
submarines with long range missiles and is set to supply Pakistan with
conventional and nuclear propelled submarines to be based at Ormara in
the future.
The Pakistan Navy has operated three French
Agosta-90B/Khalid and two Agosta-70 submarines built and modernized at
Karachi, and refitted in Turkey. Pakistan Navy’s (PN) is set to acquire
6/8 double-hulled 6,000- ton Type Diesel S-041 and S-039 Yuan Hybrid AIP
submarines. Construction of the boats has begun near Shanghai and the
first is expected by 2020 at Ormara at PNS Jinnah where joint work has
started with China as it has a naturally protected bay and inlet.
Ormara is 120 nm from commercial Gwadar, the other port China operates.
Co-operating
with the United States and QUAD partners in ASW in the Indian Ocean
will help enhance India’s ASW capacity as the Indian Ocean is witnessing
China’s increasing activity and ambition in the region.
Submarines
can shape the region’s security environment for deterrence and the
Indian Navy faces a significant under water threat in the years to come
but it is hoped with the speeding up of deliveries of the five Project
75 Scorpene submarines at one a year, and SSBN Arighat and another Akula
joining, the Indian Navy’s silent service will look up.
