India planning to upgrade Malabar trilateral to include commerce & trade: Ram Madhav
India is planning to upgrade the tri-lateral Malabar naval exercise, involving the US, Japan and India and include trade & commercial aspects as well, according to Ram Madhav BJP General Secretary and India Foundation Director.

Participating in a panel discussion on 'Towards a new framework for a new free and open Indo-Pacific' on the second day of the third Raisina Dailogue on Wednesday, Madhav said the government is thinking of upgrading it from the naval exercise to commerce and trade as well.

The three-day Dialogue, organised by the Ministry of External Affairs and Observer Research Foundation, was also participated by many ministers of India and from abroad.

"We want to include in it the commerce and trade aspects as well," Madhav said, adding that the government wants it to be for the betterment of the region, and not against any country.

"We don't want it to be seen as a group against China," Madhav said.

He said while the government is sympathetic to the request of including Australia in the group, it is also willing to take more countries of the region into the group, he said.

Japan's embassy representative also said they are agreeable to the request of including Australia in the group, but skirted the question on whether Japan's position on Madhav's suggestion of upgrading it with commercial purposes.

Madhav also felt that there is a need to look at forming new effective laws to ensure free and secure navigation in the seas as the United Nations Convention on Laws of the Seas has failed in its purpose. "I think there is a need to look at this law as well", he said, as the world focus is shifting to the Indo-Pacific Region.

He said while India and European Union is having a good relation, especially in Europe, their relationship is of little use in the region, Madhav said while replying to a question from a participant.

Madhav also felt that economic sanctions against a powerful country would not work. On the other hand, it will have more reverse impacts, he said as one questioner raised the issue of imposing sanctions.

Madhav said while it is difficult to predict the future of the world, it is sure that the future belongs to innovations and technology and whichever country would do well in this, will succeed.

Phuket hosts Thai, Indian navy emergency exercises
The exercises were the 25th such joint efforts the Royal Thai Navy has conducted with the Indian Navy.

Lt Cdr Alongkorn Bootsarasakul led the 61-strong crew on board the HTMS Long Lom through their parts in the exercises, while Cdr Syed Qais Sayat led his 145 crew on board the INS Saryu through theirs.

The INS Saryu is the first Saryu-class patrol vessel of the Indian Navy. The most advanced vessel to be constructed by Goa Shipyard Limited (GSL) in terms of design, performance and quality, the INS Saryu was launched in 2009 to the tune of US$97 million (B3.048 billion),

The Indian Navy contingent will depart Phuket tomorrow (Jan 31) to return to Port Blair, home of Andaman and Nicobar Command.

The Indian Navy joint exercises with the Royal Thai Navy yesterday followed those of the Indian Coast Guard on Jan 23.

The “PASSEX” passing exercise saw ICGS Shaunak and ICGS Rajshree of the Indian Coast Guard, which operates independently from the Indian Navy, arrive at the Phuket Deep Sea Port at Ao Makham on Monday (Jan 22).

The two coast guard vessels conducted similar joint-exercises with the Thai crews on board the HTMS Hua Hin the next day.

Both navies joined the passing exercises with the aim of the exercise to ensure that the navies are able to communicate and cooperate in case both become involved in search and rescue efforts should a real incident arise, noted a Royal Thai Navy release.

“This exercise helps naval officials at all levels to enhance their knowledge, raise proficiency and gain more experience,” the release noted.

“The Royal Thai Navy and the Indian Navy have a great relationship and clear lines of communication in operating with each other,” it added.

NPOL’s torpedo defence system to equip Navy


An artist's impression of how the Maareech advanced torpedo decoy system functions.
Defence council clears purchase worth ₹850 crore

An advanced system developed by a consortium of Indian Defence laboratories led by the Thrikkakara-based Naval Physical and Oceanographic Laboratory (NPOL) to defend naval ships against torpedo attack will now be integrated on as many as 30 ships operated by the Indian Navy.
While 11 ships will be equipped with the full system, named Maareech Advanced Torpedo Decoy System, the remaining will get just the torpedo countermeasure capability that’s part of it.

Acquisition cleared

The Defence Acquisition Council, led by Defence Minister Nirmala Seetharaman, on Tuesday cleared acquisition of the anti-submarine warfare (ASW) and non-ASW variants of the system which will be manufactured by Bharat Electronics. Initially, systems worth ₹850 crore will be acquired to arm warships.
Two systems are already functional on INS Ganga and Gomati which were used for user evaluation trials of the indigenously-developed systems.
“The survival capability of a ship is greater if the attacking torpedo can be detected early and also at a range equal to or more than the escape range of the platform under attack. A fully integrated Maareech system has both torpedo detection and countermeasure capability,’’ said R. Rajesh, NPOL scientist and spokesperson.

Tactical advantage

‘‘Also, the system offers tactical advantage by classification of the torpedo along with localisation and target motion parameters. The escape solutions are then evolved which will advise the crew of the ship on the most appropriate manoeuvre and countermeasure actions necessary to defeat the threat,” said Mr. Rajesh.
Besides the NPOL, Visakhapatnam-based Naval Science and Technological Laboratory was involved in developing the system. The torpedo defence sonar that is part of Maareech was developed by a team led by project director K. Ajith Kumar, NPOL scientist.

Major milestone

S. Kedarnath Shenoy, NPOL director, said that the induction of Maareech would be a major milestone for naval research and development as it would be the first time the indigenously designed towed array sonar system would be arming Indian warships.
With this, the NPOL has now successfully developed multiple configurations of sonars such as hull mounted sonars for ships, submarine sonar systems, towed array sonars and airborne dunking sonar systems for the Navy.

Indian Navy to get submarine rescue vehicles in June

A Scotland-based company expects to supply two third-generation deep search and rescue vehicles (DSRVs) to the Indian Navy by June following the successful completion of harbour acceptance trials.

The two complete flyaway submarine rescue vehicles are to be delivered under a £193-million contract awarded to JFD, a leading underwater capability provider, in March 2016.

The systems include launch and recovery systems equipment, “transfer under pressure” systems, and all logistics and support equipment required to operate the DSRVs.

“The initial harbour acceptance trials of the first DSRV, which were undertaken at Glasgow’s King George V dock, are now complete. As part of this process the system has been comprehensively tested in a variety of conditions,” JFD said in a statement this week.

Following the harbour acceptance trials, the DSRV will be fully integrated with the rest of the rescue system at a site in Glasgow, including the offshore handling system, intervention suite and 90-person decompression facilities.

Ben Sharples, India DSRV project director at JFD, said: “The completion of the initial harbour acceptance trials for the first DSRV, to be delivered to the Indian Navy, is an important step in the delivery of this contract.

“This is part of the progressive acceptance of the system designed to drive out risk during the later stages of sea acceptance.”

Sharples added that the third-generation DSRV marked a significant step-change in real world submarine rescue capability with its weight optimised for maximum payload and optimum transportability.

JFD said the system had been developed to maximise the chances of successfully rescuing the crew of a distressed submarine. The full certified systems are due to be delivered to Indian Navy in June, it said.

A total of 72 Indian Navy personnel have also been trained by JFD at a facility in Scotland to operate the vessels. The Indian Navy, which operates a mix of Russian and Western submarines, has for long projected a need for deep sea rescue vessels to cope with possible accidents.

Portable Diver Detection Sonar system (PDDS)
1. Product overview
PDDS is a portable sonar system capable of detecting potential underwater threats like divers and diver delivery vehicles in shallow waters. The system alerts the operator to confirm the type of threat so that effective countermeasures can be initiated in time. The system can be deployed either outboard a ship or at any location in a harbour, typically beside a wall, pier or at the sea bottom. The system consists of units under water and on shore, interconnected by water blocked cable carrying data and power supply lines. The wet-end unit is a sonar head consisting of transducer arrays, transmitter and front-end receiver electronics hardware. The shore units consist of an interface unit, a processing and display units and power supply. As an auto-alert system, PDDS performs detection, tracking and classification of divers or diver-like targets automatically and alerts the operator accordingly. The target information provided by the system includes (i) target position (range and bearing) and (ii) target dynamics (speed and course).

1519239013130.png


3.1. Wet-end Unit
The wet-end unit of PDDS consists of the transducer arrays and the associated electronics for transmitter and receiver, all housed inside a watertight enclosure. The transmitter consists of a projector array and power amplifiers. The input signal to the power amplifier is generated by the processor and fed through a transmitting controller. The transmitter is designed to generate acoustic signals of specific strength, pulse shape and pulse width that can be controlled according to the water conditions prevailing at the location of operation. The receiver consists of a hydrophone array and front-end electronics. The hydrophone array picks up the incoming acoustic signals and transforms into electrical signals. The signal strength is very low of the order of a few microvolts. Therefore, the hydrophone output is amplified using preamplifiers, and then filtered, digitized and passed on to the signal processor.

3.2. Interface Unit
The data from the wet-end unit is transmitted through a watertight cable to an interface unit, which is installed on shore or on-board ship close to the point where the watertight cable comes out of the water. The data is received in the interface unit and further transmitted across to the processor and display unit. The power supply of 220V is fed to the interface unit, from where it is supplied to the wet-end unit.

3.3. Processor & Display Unit
The Processor & Display Unit is a high performance ruggedized computer (with integrated WLAN). It performs advanced acoustic signal processing algorithms, including, Beam former, Automatic Detection, Automatic Track and Automatic classification. The detector and track output are displayed in the display with map overlay.

4. System Features
 High frequency sonar with extended detection range
 Fully automated solution for underwater security
 Detects and classifies underwater intruders with very low target strength
 Automatic alarm on detection of threat
 Capable of detecting multiple targets around 360° in the azimuthal plane

Navy carries out mega war game in Arabian sea

The Indian Navy has carried out a major review of its operational capabilities during a two-month mega war game in the Arabian Sea in which all its frontline warships, submarines and aircraft were deployed.

"This review included both, peacetime operations as well as the training and preparations for war," the Navy said in a statement.

The war game was conducted on both the seaboards of India extending from the northern Arabian sea off the coast of Gujarat to the southern Indian ocean off the Sunda Straits near Indonesia.

The Navy said the war game was the first of its kind to be conducted on both seaboards which is indicative of the Navy's threat perceptions of a two-front war.

The exercise on the eastern seaboard was codenamed 'ENCORE (Eastern Naval Command Operational Readiness Exercise) ' ,while on the Western seaboard its codename was 'Paschim Lehar'.

"In preparation for conflict, the Navy revamped its operational exercise plans to make them more contemporary and realistic. In a two-year cycle promulgated by Naval headquarters, the Indian Navy has literally 'cut the flab' in the various exercises undertaken at sea," the Navy said.

It said greater focus has been accorded to "conflict readiness" across the spectrum as well as realistic scenarios likely to be faced at sea.

"The focus has been on realistic scenarios likely to manifest in the future including terrorist attacks from sea on critical infrastructure and populated areas, defence of the offshore oil resources of the country and protection of the large seaborne trade of India," it said.

A very informative interview of Admiral Sunil Lamba.
He talks about status of security in Indian ocean, Chinese aggression in and out of Indian Ocean and strategy of Indian navy against them.
He talked about Navy response in cases like Doklam and Maldives. He confidently talked about we being able to monitor their deployments and in Indian Ocean it would be chines ball in Indian court.
