Multi-Role Helicopters are an essential part of any modern naval fleet.
They have a critical role in the fleet’s anti-submarine capabilities.
The Indian Navy’s capabilities in the area of anti-submarine warfare is
limited by its lack of modern helicopters to undertake the crucial role.
It’s after more than a decade that we seem to have reached a point
where we can expect the MH 60 R Romeo of Lockheed Martin to be procured.
The author analyses the Navy’s requirements, current holdings and the
MH 60R helicopter’s capabilities.
In
any operation at sea today modern Multi – Role Helicopters (MRH) are
crucial eyes, ears and long arms of the Fleet. The only platform that
can strike fear in a submarine Captain’s mind is the Fleet’s integral
air element of Anti-Submarine Warfare (ASW) helicopters. For India, with
neighbours who are consolidating their Navies with potent submarines,
lack of a capable MRH in adequate numbers is a critical operational
capability gap in the vital area of Indian Ocean Region (IOR), more so
because the Chinese presence in the IOR has risen sharply in terms of
both submarine and surface activity.
This vulnerability was starkly visible at last year’s annual cooperative
naval exercise, ‘Malabar’ where the Indian Navy operated alongside the
US and the Japanese Navies in the Philippine Sea. One of the key
elements of this exercise was the ‘Joint Anti-Submarine Warfare
Work-Up’, where the Indian Navy found itself vastly handicapped. While
the US and Japanese Navies strutted around their modern fleet of ASWs in
terms of the erstwhile Sikorsky, now Lockheed Martin’s MH-60R ‘Romeo’
model and S-70B Seahawks, the Indian Navy had to be content with the
1960 era Chetak helicopters for ‘Search and Rescue’ operations.
The
last attempt to acquire this class of helicopters was thwarted in 2017,
after nine years of deliberate efforts, when negotiations broke off
with US manufacturer Sikorsky over differences in pricing with the
procurement process being finally foreclosed. The helicopter selected
was Sikorsky’s S-70B Seahawk, wherein the proposal was to acquire
sixteen helicopters initially, with an option for eight more.
Under
these circumstances when India’s integral naval ASW capability is at an
all-time low, the recent US approval for the sale of 24 Naval
Multi-Role MH-60 ‘Romeo’ helicopters to India in a Government to
Government deal has come at the right moment and as a great relief to
the Navy, though the actual contract is likely to be inked later this
year.
Present Status: Naval Helicopter Fleet ::
While
the Indian shipyards continue to roll out stealth frigates and guided
missile destroyers with the latest radars, sensors and weapon systems,
their hangars remain bereft of the most crucial component, the
helicopters, especially the ASW category. Helicopters form a key
element of a naval fleet at sea due to its ability to easily operate
from frigate size ships and carry out diverse roles from ASW to
Electronic Warfare, Airborne Early Warning (AEW) and Search and Rescue.
Presently
The Indian Navy operates a helicopter fleet consisting of the Sea
King-42B and Kamov-28 ASW helicopters, the Kamov-31 AEW helicopter and
the modified Chetak-MATCH (Mid Air Torpedo Carrying Helicopter). In
addition, they have a fleet of Chetak helicopters for shipborne
operations. These helicopters are old vintage and in inadequate numbers,
with most of them needing replacement and upgrade.
The HAL
manufactured Dhruv (naval variant) was inducted into the air arm in
March 2002. However, the Navy found the Dhruv unsuitable for its role
as an ASW platform, though they may continue to procure limited numbers
for employment as multi-role utility platforms- 16 Dhruvs are now part
of the naval fleet. The Kamov-31 AEW helicopters acquired from Russia in
the 1990s have proved to be a versatile platform for airborne
operations at sea but their numbers are limited. However, the main
workhorse’s in the ASW category, the British Sea King-42B and Russian
Kamov-28 are old and lack availability of spares to keep them flying and
their much required replacement process has floundered for over a
decade plus.
Presently, the Navy has a highly limited inventory
of 12 Sea King-42B and 10 Kamov-28 ASW helicopters to look after the 150
plus warships, leaving a critical void in this vital segment of ASW. In
fact, the Kamov-28 ASW helicopters held are currently undergoing an
upgrade under a $294 million deal inked with Russian Helicopters in
2017. Some of these helicopters have already been upgraded. The upgrade
involves engine overhaul and fitment with state of art sensors and
avionics. The Navy requires at least 123 Naval MRH and had released a
global request for information in August 2017. As usual, no progress has
been made on this critical project till now, due to bureaucratic
lethargy in failing to finalise the ‘Strategic Partnership Model’ under
the ‘Make in India policy’.
Case for MH-60R ‘Romeo’ MRH ::
Keeping
in mind the dire need and critical requirement of the Navy for
helicopters that can undertake missions ranging from anti-submarine
operations to fire support and early warning at sea, the Defence
Acquisition Council (DAC) cleared the procurement of 24 MH-60R Seahawk
multi-role helicopters in August 2018. Thereafter, in November the
Government made a formal request to the US Government for the purchase
of these helicopters under the ‘Foreign Military Sales’ (FMS) route.
Accordingly,
a ‘Letter of Request’ was given to the US Government for the
acquisition of these helicopters as an urgent requirement. The US in
April this year has approved the sale of 24 multi-role MH-60 ‘Romeo’
Seahawk helicopters to India at an estimated cost of $2.4 billion, under
the FMS route–these Sirkorsky/Lockheed Martin-built helicopters will
replace India’s ageing fleet of British-Westland Sea King Mk 42B and
Russian Kamov Ka-28 helicopters.
The twin-engine MH-60R is the
world’s most advanced maritime helicopter armed with Hellfire Missiles,
MK-54 Torpedoes and precision kill rockets for potent ASW capabilities
and is currently deployed with the US Navy as the primary anti-submarine
warfare/anti-surface weapon system for open ocean and littoral zones.
According to industry experts, it is the most capable naval helicopter
available today, designed to operate from frigates, destroyers, cruisers
and aircraft carriers, with the capability to handle numerous contacts
in confined spaces, as well as for open-water operations.
MH-60
Romeo Seahawks will add lethal capabilities to the Indian Navy, which
indeed is the need of the hour, given the aggressive behaviour of China
in the Indian Ocean region. According to US Naval Air System Command,
the MH-60R Seahawk missions are anti-submarine warfare, anti-surface
warfare, surveillance, communications relay, combat search and rescue,
naval gunfire support and logistics support.
The helicopter has a
fully integrated mission system which builds complete ‘Situational
Awareness’ and ‘Actionable Knowledge’ enabling target engagement both
close-in and over the horizon. The MH-60R is also fitted with a suitable
‘Cargo Hook’ for vertical replenishment missions. The helicopter has
dual controls and is equipped with a digital integrated glass cockpit.
More than 300 of these helicopters are in operation with the Australian,
Danish, Saudi and Qatar Navies including the US and have accumulated
over 60000 flight hours.
In addition to the helicopters, the
purchase will include a multitude of support and embedded equipment like
engines, multi-mode radars, sonobuoys, weapon systems and other
essential associated equipment. In addition, the US will provide night
vision devices, high-frequency radios and identification friend or foe
transponders as part of the deal. India will also receive personnel and
equipment training, as well as support for engineering, technical and
logistics support services.
MH-60R Seahawk Characteristics ::
The
Seahawk is powered by two General Electric T-700 turbo-shaft engines
with a rating of 1425 kW. It has a maximum speed of 267 km/hour, a range
of 834 km and a service ceiling of 3435 metres. With regards to weapon
systems, the helicopter can be equipped with a range of weapons on the
four weapon stations, with the AGM-114 Hellfire missiles for
anti-surface missions and the ATK MK-54 active/passive lightweight
torpedoes for ASW- it can also be mounted with a 7.62mm machine gun for
self-defence.
The helicopter is fitted with a modern and advanced
Electronic Warfare (EW) suite and state of art sensors. For
anti-submarine operations, it is equipped with a Sonobuoy Launcher and
an advanced Airborne Low-Frequency Dipping Sonar. The MH-60R is also
fitted with a detecting/tracking system which includes a FLIR and laser
rangefinder. The MH-60R Seahawk incorporates all such features which
enhance survivability. It can withstand small arms fire and medium
calibre high explosive projectiles and has a self-sealing fuel tank. The
flight controls have dual redundancy, with the upper controls and hub
being ballistically tolerant. The helicopter is fitted with high energy
absorbing landing gear and its high mass components are retained in case
of a high impact crash. The survivability features of the MH-60R rank
amongst the best in helicopters.
The Navy is inducting four to
five warships every year, in tune with its plan to become a 212 strong
warship force by 2027 and has virtually run out of the MRHs to operate
from their decks to detect, track and kill enemy submarines. Most of the
warships have been operating with a Chetak helicopter instead, for
multi-purpose duties, a helicopter that is even older than the limited
Sea King helicopters held and is itself awaiting replacement for over a
decade.
The critical shortage of helicopters has emerged as the
most alarming operational gap in the Navy today. Given the critical
situation, the US approval for the sale of 24 MH-60R Seahawk under the
FMS route could not have come a day later – the contract for the same
needs to be signed at the earliest. Navy’s requirement is of 123 Naval
Multi-Role Helicopters (NMRH) for which a global Request for Information
(RFI) was released in August 2017. However, despite the critical
operational situation, the NMRH programme has not progressed as fast as
the Navy would have liked and currently runs the risk of getting stuck
in a bureaucratic quagmire if a clear strategy is not evolved.
Under
the circumstances the MH-60R Romeo Seahawk is a suitable NMRH platform.
Going in for 24 of these next-generation submarine hunter and
anti-surface warfare helicopters is an excellent plan. It would be
practical to pursue additional induction of theses helicopters under the
Strategic Partnership Model of the Defence Procurement Procedures.
