Mahindra Defence Naval Systems has partnered with Ultra Electronics UK for the development of underwater warfare equipment for the Indian Navy.

The new collaboration will build and deliver new-generation advanced systems, including the new torpedo defence system (NTDS), integrated anti-submarine warfare defence suite (IADS), and mine counter-measure (MCM) equipment.

The companies will focus on other programmes, including systems for anti-submarine warfare (ASW) vessels, submarine safety equipment, sonobuoys, and underwater ranges.

Mahindra Defence Naval Systems chairman SP Shukla said: "The Indian Navy has been importing a major part of underwater war fighting equipment from abroad to service its needs.

"We expect to provide cutting edge technology to the Indian Navy in this field in partnership with Ultra Electronics."

The partnership will also address the requirement of specialised radios for the Indian Army's tactical communication systems.

"We expect to provide cutting edge technology to the Indian Navy in this field in partnership with Ultra Electronics."

In a separate development, Ultra Electronics' Staffordshire-based PMES business secured £18m a contract from Rolls-Royce for the design and development of reactor control and cooling systems for the UK Royal Navy submarines.

The new contract will support Rolls-Royce in its delivery of the next-generation propulsion power system for the future submarine fleet.

Recently, Mahindra Defence agreed to collaborate with Airbus Helicopters to manufacture helicopters domestically to meet India's military requirements.

As part of this development, both firms will establish a new joint venture company, which would become the first private Indian helicopter builder under the country's 'Make in India' initiative.

The JV is expected to act as the prime contractor for the country's military helicopter tenders, including the reconnaissance and surveillance helicopter, the naval utility helicopter and the naval multirole helicopter procurement programmes.

It was the army that put the requirement for a rifled gun .

I don't know why would they do that, but it is obviously a mistake. Such guns are obsolete in modern times, almost everybody except British switched to smooth-bore (and even British planed to actually do that before budget cuts) .

untrue , usual nonsense by import lobbyists

Don't know about that, but Arjun MkI is relatively light compared to its size . It is quite possible it has some weak areas, otherwise why would Mk II add almost 10t of new weight ?

there was one more reason the Challenger 2 was not regunned the ammo storage bunker was designed for two piece ammo. Changing the Gun to Nato standard would mean one piece ammo so the tanks ammo storage space would need a redesign.
As to Rifled vs smooth bore. I view it more as a choice based on perceived threat. Rifled guns fire a wider selection of rounds especially antipersonnel types then smooth bore. Well smooth bore are better tank killers.

For the record there is a technology that can compensate for use of Sabot rounds through rifled barrels slip rings which sit between the round and barrel act to seal and lubricating the firing to reduce rotation of the round. Its still a sacrifice though.

its all about where the armor is how it is shaped and what its made of. The Russians new Armada advertisements say best protected tank ever yet for its size its light, to pull that off the Russians use armor modules a unmanned turret and focusing the armor around only the most important things.
Abrams has been accused of being a sham because of perceived weaknesses in its armor from the side or rear, yet Abrams optimized its armor to focus on face to face fighting.
Basically it might be that the MK2 redesign fixed that issue by moving more armor to the perceived soft spot from some other point on the tank.
Still have to watch this and see if its all that's advertized. As I pointed to in the MCAR there is some evidence that preferential treatment is being given in the Indian army.

The indigenously made nuclear submarine – INS Arihant – will fire its first missile, also made in India, this year to formally complete the nuclear triad for India, according to top defence research officials. Arihant will also go for its first deep sea dive soon, giving India the ability to launch a nuclear missile from air, land and sea.

In an exclusive interview to NDTV, the newly appointed Director General of Defence Research & Development Organisation (DRDO,) Dr S Christopher said that India is in the process of building two more Arihant-class-submarines.

The firing of the indigenously made missile is capable of delivering a nuclear pay load, an important milestone for India’s defence production. It signifies the completion nuclear triad. The missile code named B-05 will be India’s first Submarine launched Ballistic Missile (SLBM).

“If all goes well we will show case this capability in the International Fleet Review (IFR) next January. DRDO is working on the next SLBM code named “K-4″ which will have a much longer range,” Dr Christopher said.

Nuclear submarines are strategic assets and typically stay deep inside the sea ready to launch in case of nuclear strike. This is critical since India follows doctrine of no first use of nuclear weapons.

While Dr Christopher refused to disclose the ranges and pay load carrying capability of either of two SLBMs developed by India, information available in the open domain indicate that the B- 05 can carry a one tonne war head.

In comparison China has five nuclear submarines, Shang Class, who fire the Julang -2 missiles which are believed to have a range of 8000 Km.

India is also likely to carry out a third test for Agni- V this December, the missile has a range of over 5500 kilometres. By perfecting this technology, India will join the elite group of countries that have Inter-Continental Ballistics Missiles (ICBM). About 6 countries claim apart from North Korea claim to have ICBM.

According to Dr Christopher, three successive successful test of Agni- V would clear the decks for the induction of the missile into the military.

The final agreement for the joint development and production of a fifth generation fighter aircraft could be signed during Prime Minister Narendra Modi’s visit to Russia in November, diplomatic sources told The Hindu on Thursday.Preparations are under way in both countries for the summit-level meeting to impart a qualitative boost to defence cooperation.

Agreeing that differences exist, sources said without getting into the details that “a workaround has been found and discussions are in an advanced stage” and an agreement could be reached “by autumn”. The final deal is likely to be signed in November.

The agreement on the fighter aircraft has been stuck because of differences in the work share between Sukhoi and Hindustan Aeronautics Ltd. (HAL). As the project is to have equal investment from each side, India has been insisting on parity in the work share. So far, both sides have invested $295 million for the preliminary design. India had some reservations on the engine and stealth characteristics.

India has requested Russia to let its pilots fly the T-50 prototypes currently under testing. A decision by Russia on this is expected shortly. India plans to induct 144 fighters and the entire project is expected to cost over $30 billion. The first batch of aircraft is expected to be handed over to the Russian Air Force in early 2017

India is in talks with Indonesia to export indigenously-made Air Borne Early Warning and Control System (AEWAC), Dr Christopher said. This would first major export of defence systems from India under the PM Modi-led NDA government and the move fits into the government's push to reduce import of weapon systems and increase exports.

Besides, the export of AEWAC - a complex aircraft mounted system - also indicates India's late but sure entry into the weapons market.

"The government has clearly told us that expect technology and system that fall in the strategic we are free to export," Dr Christopher told NDTV.

On being asked how he rated the Indian Private sector and its contribution to defence research and development, Dr Christopher said that for Make in India to be successful in defence systems with the private sector taking the lead "there is need to hand hold" the private companies. Development of defence systems is time consuming and costly. "The government could consider a fund to help out the private sector," he said.

While waiting for the final Sea tests for the new Shtil-1, frigate-launched surface to air missiles, India has expressed interest in purchasing this upgraded SAM for its Navy. It is possible that China, which also owns earlier models of the Shtil, will be interested in buying the SAM for its frigates.

India has shown interest in buying the new Shtil-1 naval surface to air missile (SAM) systems, being installed on frigates 11356 project, Maxim Kuzyuk, Tekhnodinamika General Director, told RIA Novosti.

"Now everyone is waiting for the state testing of the first ship of the ‘Admiral series’ (project 11356) to be complete. That is when the new SAM will be accepted into service with the Russian Navy, after which it will be possible to deliver it overseas. Today India has shown interest in acquiring the new Shtil. We are discussing deliveries as part of the upgrade of old vessels and the construction of new ones,” Kuzyuk said.

India has already received six ships of a similar class to 11356, but they were equipped with an old model of the Shtil, which can launch once every 12 seconds, while the new Shtil-1 can launch once every 1.5-2 seconds.

The Shtil-1 may also interest China, whose forces are armed with the old version of the SAM.

"China has six project 956 destroyers which are armed with the Shtil. Russia also has such vessels. Repairing the old SAMs is meaningless. Therefore, in the future, the current upgrade may interest not only the Russian Navy, but also our Chinese partners,” said Kuzyuk.

Launch and ground equipment for the medium range Shtil-1 SAM is produced at the scientific-manufacturing enterprise “Start” (which is part of the Tekhnodinamika holding). The system is designed to engage all the modern means of air attack at medium range and at altitudes from five meters to 15 kilometers. A distinctive feature of the system is the use of the updated surface-to-air missile with a vertical start, and the use of multi-function radar with phased array antennas.

The Project 11356 frigates (being built at the Yantar ship docks in Kaliningrad on the Baltic Sea) are designed to carry out military operations in the ocean against enemy submarines, and to resist aerial attack, both independently and as part of a convoy of ships. At present there are six Project 11356 frigates being built for the Black Sea Fleet, which are to be launched by 2016.

To make up flagging warship numbers, the Indian Navy is initiating the purchase of three Grigorivich-class frigates (Project 1135.6) from Russia. These warships are improved variants of the six Talwar-class (Russian classification: Krivak-III) frigates the navy obtained between 2003-13.

Those earlier vessels were built in Russia, in Yantar Shipyard at Kaliningrad, on the Baltic Sea. Now New Delhi insists the new frigates be built in an Indian shipyard.

Just two Indian shipyards have ever built a frigate --- Mazagon Dock Ltd, Mumbai (MDL) and Garden Reach Shipbuilders & Engineers, Kolkata (GRSE). With these two occupied with building seven stealth frigates under Project 17A, Yantar will partner a private Indian shipyard.

Business Standard learns that Russian experts have evaluated three private yards for their potential to build these frigates: Larsen & Toubro’s Katupalli shipyard, at Ennore, Tamil Nadu; Pipavav Shipyard in Gujarat; and Cochin Shipyard Ltd (CSL) in Kochi, Kerala.

“The Russians will take a commercial decision on which Indian shipyard to partner. We will not interfere”, says a senior Indian naval officer, speaking on condition of anonymity. Once they decide, the navy will formally initiate the procurement, he says.

India paid about $1 billion for the first three Talwar-class frigates, and a similar price for the next batch of three. However, the current trio could be significantly more expensive. This would partly be due to inflation, while building in India would further boost the cost.

Driving the navy’s decision to buy three more Russian frigates is a growing warship shortfall. The maritime capability perspective plan envisages a 198-ship navy by 2027. Against that the navy currently has just 137 vessels.

Short by 61 warships, the navy currently has 48 vessels under construction. In addition, the defence ministry has accorded sanction (termed Acceptance of Necessity, or AoN) for another 44 vessels, including six Project 75I submarines.

Over the coming two decades, while these 92 vessels are built in various Indian warships, large numbers of older warships would be decommissioned at the end of their service lives. While decommissioning can be delayed to some extent, the navy will still be well short of 198 vessels by 2027.

Given this vulnerability, New Delhi listened carefully when Russian President Vladimir Putin offered Prime Minister Narendra Modi three-to-four Project 1135.6 frigates during their summit meeting in New Delhi last December.

Neither Russia nor India publicly acknowledged Putin’s offer, but the joint statement of December 10-11 stated: “President Putin and I discussed a broad range of new defence projects. We also discussed how to align our defence relations to India's own priorities, including Make in India.

This was a familiar convergence of interests between a penurious Moscow and an inefficient New Delhi. Russia’s Yantar Shipyard has six Project 1135.6 frigates under construction, but Moscow can no longer afford them, due to low oil prices and sustained economic sanctions from the West over the Ukraine confrontation.

The Indian Navy is satisfied with its Talwar-class frigates, which is why they may go on to become the largest warship type in the Indian Navy, with nine in service.

With a displacement of just 4,000 tonnes, the Talwar class packs a considerable punch owing to a key Russian design strength: outstanding utilisation of space. The Russian designers even squeezed in torpedo launchers, which are only now being retro-fitted into the larger Indian Shivalik-class frigates, which displace 5,600 tonnes.

Like the Shivalik-class, the three Russian frigates will be multi-role vessels. They will carry the Brahmos surface-to-surface missile for attacking land targets and ships; an improvement over the Klub missile carried by the first six Talwar-class frigates. Like them, they will be fitted with Shtil anti-air missiles, naval guns and rockets, and torpedoes for sinking enemy submarines.

The Shivalik-class’ biggest capability advantage stems from its carriage of two multi-purpose helicopters of the 10-tonne class (currently, the Seaking), while the smaller Talwar-class frigate can only accommodate a single Kamov-31. The embarkation of two helicopters instead of one effectively doubles a frigate’s anti-submarine and airborne early warning capabilities.

However, the greatest advantage the navy sees in buying Russian frigates is they would be delivered far quicker than Indian vessels. Sources say Moscow has offered to provide the first frigate within 2½ years of the order, while an Indian shipyard would take at least 1½ years longer.

History was created at Air Force Station Gwalior on 10 Jul 15 when Hon’ble Raksha Mantri Shri Manohar Parrikar formally handed over to the Indian Air Force (IAF) the indigenously designed, developed and produced Akash Air Defence missile system. A befitting ceremony was held to mark this historic event which saw the presence of the top leadership of not only the Air Force but also of the Secretary Defence (R&D) Dr S Christopher, the Chairman and Managing Director of Bharat Electronics Limited (BEL) SK Sharma and the first Project Director of Akash Missile system Dr Prahalada. It is pertinent to note that Akash is the first made-in-India missile system and is a hallmark of sustained and focused jointmanship between DRDO, BEL, private sector and more importantly the IAF.

Earlier, on his arrival at Air Force Staion Gwalior, Shri Manohar Parrikar was received by Chief of the Air Staff Air Chief Marshal Arup Raha. He then inspected the ceremonial Guard of Honour against the backdrop of two Sukhoi 30 MKI, one MiG-21 and one Mirage 2000 aircraft. Thereafter he witnessed the live demonstration of the missile system wherein ‘live’ tracking of fighter aircraft was carried out by switching on the radars.

The handing over ceremony was marked by a spectacular display of a drill by the operating crew of Akash Pioneers, the first unit in the IAF to induct this system. Speaking at the occasion, the Raksha Mantri lauded the efforts of the DRDO, BEL, public and private industries, inspection agencies and the end user who all worked together to resolve a number of challenges that arose during the production of the Akash Missile system. He added that the benefits of the Make in India programme such as employment generation, financial growth, self sufficiency and better defence preparedness were there for all to see.

Air Chief Marshal Arup Raha, who formally received the ‘key’ of the Akash system from Shri Parrikar said that a total of 27 missiles had been fired after inking of the contract, to ascertain the serviceability of the system in various conditions and a high success rate had been achieved. He also brought out that plans were afoot in the IAF for procurement of additional Akash systems.

Akash is a potent supersonic mobile multi-directional, multi-target point/ area Air Defence system that can simultaneously engage multiple air targets using sophisticated multi-function phased array radars. The advanced ECCM (Electronic Counter Counter Measures) features provide secure communication links with other Air Defence Command and Control networks to handle the counter electronic warfare scenario.

Indigenous development of Akash system has given impetus to the defence industrial base of the country and generated business of more than Rs. 20,000 crore. Akash is the outcome of successful partnership between DRDL, the nodal lab in DRDO, along with 13 other DRDO labs, 19 Public Sector Units (PSUs), 5 Ordinance Factories (OFs), 3 National Laboratories, 6 academic institutions and more than 265 private industries across the country.
