CAG reports aren't very reliable according to some so take it with a grain of salt. And it's an incredibly moronic move on CAG's part to actually publicize such supposed shortcomings in the public forum. These kind of matters should be discussed with armed forces and MOD and appropriate actions should be taken

Because we are potentially on a two front war and putting out such moronic reports puts us on a weak spot? Perception matters as much as reality

India's Mareech Anti-Torpedo System Ready For Induction
Source : Our Bureau ~ Dated : Monday, October 26, 2015 @ 06:54 AM

Indian Naval Science and Technological Laboratory has developed an advanced torpedo defense system to divert incoming enemy underwater torpedoes and is ready for induction.

The torpedo defense system, Maareech has completed trials and will soon be inducted into the Indian Navy, Asian Age News daily reported Saturday.

“It’s for the first time that such a decoy system has been developed for surface ships. It’s also an advanced version of the regular decoys. It is ready to be officially inducted. The Navy has accepted the decoy system and it can place the orders for its ships now,” V. Bhujanga Rao, DRDO director-general, naval systems and materials was quoted as saying by the news daily.

The NSTL is awaiting defense minister Manohar Parrikar to visit the lab at Vizag to officially launch and induct the system.


While submarines use decoys as anti-torpedo systems, the system has been developed for surface ship for the first time. After completing trials at various stages, the prototypes of Maareech were tested. The Navy has accepted the system and is ready for formal induction. The NSTL took almost eight years to develop the “complex system.”

Maareech, will be manufactured at, Bharat Electronics Ltd., Bengaluru.

^^^

Is Mareech integrated with RBU-6000? That would provide hard-kill option between 350m to 5.8km. Maybe the front location of RBU-6000 on a 180-degree traverse launcher would keep from launching at the ship's own towed array/decoy.

These Incredible Weapons Are Made In India

Considering the national wealth it commands, India’s hard power shouldn’t be dismissed. As a matter of fact, as early as 1947 India possessed the best trained military in Asia. A strong British core was the rock upon which a professional institution was molded and outfitted with a proper navy and air arm.

In the decades that followed a growing state-owned domestic arms industry improved this state of affairs. There was no realm Indian scientists and engineers ventured that didn’t impact its military advancement. India also cultivated its allies from opposite sides of the Iron Curtain, an approach that remains profitable to this day.

As the 20th century surrendered to the 21st, India emerged as a leading arms importer while its military-industrial complex struggled with the development of cutting-edge weapons.

Glaring shortages in materials and capabilities persist in India’s massive armed forces. But new hardware, from tanks to stealth warships, are rolling out of state-owned factories with alarming frequency. This is a sure sign India is preparing for an active role in global affairs.

Just like China, India is arming itself to fortify its economic advancement and dominate the region. Its current path might be frustrating, but the intent is clear: India is the would-be arsenal of the free world.

Orange to add teeth to India’s gen-next weapon systems

Image
Hyderabad, Oct 27: Future missiles and Unmanned Aerial Vehicles (UAVs) being developed by India will be tested for their Radar Cross Section (RCS) measurements at the recently-opened facility codenamed Project Orange (open range) in Dundigal near Hyderabad.

Orange is a Defence Research and Development Organisation (DRDO) project operated by Dr A P J Abdul Kalam Research Centre Imarat (formerly RCI). It is being developed as a national facility for RCS measurements, which is capable of enhancing the stealth features of India's gen-next weapon systems.

Giving exclusive details to OneIndia, an official said that Orange is capable of measuring RCS over a wide frequency band for various platforms. The facility was recently opened by Defence Minister Manohar Parrikar.

"Orange can be used to test platforms currently in use by defence forces and those futuristic weapon systems under development. The facility presently covers frequency ranges in far field scenario and is capable of providing RCS measurements as well as onboard antenna characteristics," the official, requesting anonymity, said.

Know more about Radar Cross Section (RCS)
RCS is the parameter that determines the detectability of an object by a radar. A larger value indicates that an object can be detected at far distances compared to one with small RCS value.

The RCS of a object is defined in far field, i.e., distances where the electro-magnetic (EM) energy spread out by the emitter has achieved a steady state scenario and antenna pattern does not change with distance.

Radars are used worldwide over a wide frequency band starting from VHF to millimeter waves (MM-waves) for various purposes. Low frequency radars have the advantage of transmitting a very high power and are utilized for early detection. However, for tracking purpose (a seeker for example), higher frequencies are used, which have the advantage of higher resolution, though transmitted powers are limited.

Facility can take loads in excess of 75 tonnes. The official said that Orange is being established in an open (outdoor) configuration with a range that's capable of addressing the requirements of a full-scale vehicle.

The Pylon system is capable of lifting payloads up to 35 tonnes by a height of 10 meter above ground, necessary for aerial targets.

"The base rotor of the pylon has the capability of taking loads in excess of 75 tonnes which is to be utilized for RCS and antenna measurements of heavier ground vehicles, including tanks and radars. The pylon has three detachable rotors with varying payload capacity," the official said.

The capacity of the pylon is capable of addressing the requirements of scale models, dummy mockups, operational light aircraft and even heavy fighter such as a Su-30MKI.


Many home-grown technologies incorporated Orange boasts of many home-grown technologies developed with the support of DRDO. The Instrumentation Radar System (capable of measuring low RCS values) at the test range is co-developed by Bose Institute, Kolkata and Sikkim Manipal Institute of Technology (Rangpo), Sikkim.

"The RCS measurement and calibration technique for the test range is based on RCI's two-decades-plus expertise in this domain. In addition to RCS measurements, the RF imaging capability of the range is capable of diagnosing the hot spots (prominent scattering centres) on a platform," he said.

Based on the levels of hot spots, the vehicle can be subjected to a redesign or even put through RCS-reduction materials. "It all depends upon the overall RCS reduction achievement in a defined threat sector of a given vehicle," the official added.

Interesting....How many total GT projects we are having concurrently?? I can count these:
- 3 small engines - HAL/RCI/GTRE
- 2 Kaveri - 90kn class and 110kn class - GTRE
- GT for Tanks based on Kaveri core - GTRE

Also BHEL has developed power turbine module for Kaveri for power production, per what I heard from someone who has lot of chaiwala friends. He also mentioned that Kaveri turned out to be excellent for naval application. But I haven't heard of any Naval version of Kaveri so far.

Seems a lot of use is done of competencies gained by GTRE from Kaveri project.

I am missing any more projects for GT??

Built for air force, Kaveri engine chosen by navy
8th Sept 09

The indigenous Kaveri aircraft engine, soon to make its debut flight, lacks the muscle needed by India’s Tejas light combat aircraft, which the engine was designed to power. In its present form, the Kaveri will never power a modern fighter.

But the engine’s technology --- developed by the Defence R&D Organisation, over two decades, at a cost of Rs 3000 crores --- will not be wasted. The Indian Navy is snapping up the Kaveri for powering its growing fleet of warships.

Business Standard has learnt that the navy has officially informed the Gas Turbine and Research Establishment (the DRDO laboratory that developed the Kaveri) that naval warships will needs 40 Kaveri Marine Gas Turbines (KMGTs) over the next 15 years.

In an important signal of its support, the navy has agreed to fund 25% of the cost of the KMGT project.

GTRE has developed the marine Kaveri by modifying the aero engine with a shaft, through which power can be delivered to a propeller. The navy has extensively tested these engines at Visakhapatnam and found that the marine Kaveri can deliver 12 Megawatts (16,000 Horsepower) of propulsion power.

Typically warships run on regular diesel engines; gas turbines (such as the Kaveri) are added on to provide “boost power”, needed for manoeuvring in battle. Contemporary gas turbines, such as the General Electric LM2500, provide India’s latest 5000-tonne Shivalik class frigates with 22 MW of boost. The Kaveri’s more modest 12 MW is sufficient only for smaller warships.

While the marine Kaveri’s basic performance has been established (even the PM has seen a demonstration in Visakhapatnam), the GTRE Director, Dr Mohana Rao, is not yet satisfied with the basic design.

“So far, the KMGT is just a spin-off from the aero version”, Rao told Business Standard in Bangalore. “I want to give the navy an engine with far greater endurance. An aero engine’s life is just 3000 hours; a marine engine’s life should be 30,000 hours. I must physically test the KMGT for at least 15,000 hours.

GTRE is going ahead with developing 3-4 test engines and beginning trials within three years. The trials will be conducted in a marine environment, which will include high humidity, and prolonged exposure to salt.

We plan to begin delivery in about 6 years”, says the GTRE Director, “We hope to keep the cost below Rs 25-30 crores, which is considerably cheaper than buying imported gas turbines.”

Earlier this year, the US State Department had stopped General Electric from fitting its LM-2500 turbines on the INS Shivalik, apparently because GE had not obtained proper permissions from the US government.

Other than the 40 KMGTs, the Indian Navy has also issued a letter, on 6th April 09, laying out a requirement for 42 Gas Turbine Generators, or GTGs. These are de-rated versions of the marine Kaveri, which will be used for generating electrical power on warships. Each GTG generates 1.2 Megawatts of power.

The Indian Navy, an enthusiastic proponent of indigenisation, proposes to replace the diesel generators fitted on older warships with the Kaveri GTG. If it performs well over a period of time, the new-generation warships will also get electrical power from the Kaveri GTG.

Currently, only the Rajput and Delhi class of destroyers use gas turbines for power generation.

Vietnam upgrading submarine hunting boats Petya protector?


(Knowledge) - Most likely the submarine hunting boats Petya Guardians of Vietnam Navy is going to be equipped with the advanced hydroacoustic developed by India.


Daily News quoted the representative authorities and technical cooperation and defense of India said Bharat Electronics Company Limited (BEL) of India is negotiating the sale of hydroacoustic positioning system BEL HMS-X2 for Vietnam. These systems can be fitted on the ship Petya class submarine hunting squire capital Vietnam Navy is being used.

A senior official of BEL Daily News interview, said the company has conducted performance testing of hydroacoustic positioning system BEL HMS-X2 in the presence of officials in Vietnam a visit to BEL in the recent period.



Currently Navy Vietnam still maintained that the Team 5 underground train hunting squire Petya class Soviet past aid.

And external current Vietnam some other countries are also paying attention to hydroacoustic positioning system HMS-X2 produced by BEL, however it was the Institute for Defense Development and India (DRDO) development and design.

Acoustic Positioning System HMS-X2 design is quite compact and can be easily integrated in many different warships form, as guardian ASW ship, coastal patrol vessels and patrol boats normal. Reportedly the hydroacoustic navigation system produced by BEL are extensively equipped warships Indian Navy.

HMS-X2 BEL mainly used hydroacoustic positioning technology actively combines with passive, earlier last year India also recently announced agreement to supply navigation systems for the Navy's new hydroacoustic Myanmar estimated value over $ 29 million.


Petya class is the NATO designation for class vessels Project 159 submarine hunting squire Soviet production from 1960s ships with 1,150 tons of water, 81,8m long, equipped with anti-submarine sonar systems staging submarine hunting weapons including anti-submarine bomb four launchers RBU-6000 (or two pedestal RBU-1000), five 406mm torpedo tubes.

According to that news report the plan in late 2009 was the following:
  • 2012/3 -> begin trials with 3-4 engines KGMT; need to test for at least 15,000 hours life
  • 2015/6 -> begin deliveries of KGMT (40 ordered)
  • ? -> no date given for 42 K GTG


Someone needs to verify.

This to prove GTRE couldn't deliver hence we have to import.
As they seeing is believing no?

PM Modi for indigenous manufacturing to cut defence budget by 50%

"Today our nation imports defence equipment in large quantity. Is it not possible that our institutions concentrate in the area of defence and research and prepare a human resource development pool which will help in making equipment cheaper to the extent that outside importers use this talent for manufacturing. India can be a global market if we do it.

"If our institutions decide today that we will be able to cut down defence import by 50 per cent in next 10 years, then the amount we save on our defence budget will be pumped into the education sector. Will it not be a big gain? We will be self-reliant," he said.

How is the 50% import reduction going to happen in next 10-years when some $20 billions worth of imports are in the pipeline for French Rafales and Russian weapon systems like S-400? Let's not forget billions of dollars worth of deals with the Americans and Israelis are also in the pipeline.

Scared the hell out of me when I read the headline. It should say "cut the defence import by 50%" instead of "cut the defence budget by 50%". Big difference....

Army gets Bharat Electronics' upgraded L70 guns.

The first two numbers of L70 upgraded guns, designed, developed and manufactured by defence PSU Bharat Electronics Limited (BEL) for the Indian Army have been delivered to the latter.

BEL, which has delivered the upgraded guns within the stipulated nine months, says: "The L70 gun upgrade is a fusion of the latest technologies in the areas of electrical servo drives, electro optical fire control system and video tracking, which only a few global companies have mastered."

BEL had won the Rs 575-crore order in a global open tender issued by the Indian Army, subsequent to clearing all field trials.

"Right from the designing the upgrade to establishing a production line, the project was meticulously executed," BEL said.

Each building block of the gun upgrade — processor and interface boards, power amplifiers, stabilised pedestal, high precision mechanical subsystems, video tracker and fire control solutions — were designed in-house.

A cross functional team of engineers from all disciplines immensely contributed to the success of the project. BEL, with the support of Ordnance Factory Board, is all set to deliver 200 upgraded guns within the stipulated time of three years.

"The L70 gun upgrade is a fusion of the latest technologies in the areas of electrical servo drives, electro optical fire control system and video tracking, which only a few global companies have mastered," says a BEL official. He said the BEL stuck to the order plan right from the beginning, to ensure timely delivery.

Karan M,

though OT for the thread, are we importing the actuators for LCA from MOOG? there is this WIPRO facility in Bengaluru where they are manufacturing the actuators among other things. or has the facility not taken off?

The gestation period of some of these programs is instructive. I found an aero-India photo of this from some years ago - will post. Happy to see it reaching fruition

Also electro-mechanical drives gets rid of the leaky hydraulics and decreases the over all system time constant for response.

So why is there a need to import AD guns again? Couldn't they do more advanced versions of this similar to what they are doing for Bofors 155mm -> Dhanush -> ATAGS? This shows that the capability exists within India.

The L/70 are 1960s vintage. The design is WWII vintage. Used to be called L/60 then.

IISc prof develops system to reduce chopper crashes
Ramzauva Chhakchhuak, Bengaluru: Nov 10, 2015, DHNS:
Experts say the technology will go a long way in achieving the zero-accident vision of the International Helicopter Safety Team. DH FILE PHOTO

An associate professor in the Department of Aerospace Engineering at the Indian Institute of Science (IISc) here has developed a real-time online health monitoring system for tail rotor flexbeams that can “greatly reduce the chances of helicopter accidents.”

“Considering the fact that tail rotor failures have frequently caused fatalities, the potential for taking this research further for the benefit of the worldwide helicopter community is immense,” Dineshkumar Harursampath, the associate professor, said in a statement to Deccan Herald. He developed this system by collaborating with his former students.

In the lead up to the fourth Asian-Australian Rotorcraft Forum, to be held in Bengaluru from November 16 to 18, the Non-linear Multifunctional Composites Analysis and Design (NMCAD) Lab at the IISc hosted a lecture on Friday by James A Viola, an internationally recognised expert on helicopter safety. Viola is a co-chair of the US Helicopter Safety Team and manager of the Federal Aviation Administration’s General Aviation and Commercial Division. He is also a government member of the General Aviation Joint Steering Committee. He showed interest in the system, Prof Harursampath said.

Most of the people who keep reading about helicopter crashes aren’t aware that rotary wing aircraft can be safer in many situations than fixed wing ones. “For example, after an engine failure, an alert helicopter pilot can utilise the momentum in his rotor to safely land through its timely disengagement. In the absence of such autorotation feature, landing an aircraft in a similar situation is much tougher, if not impossible in the case of single engine military aircraft. In this context, James and his International Helicopter Safety Team’s (IHST) long-term vision of ‘zero accidents’ is not just wishful thinking,” said Prof Harursampath. Their short-term goal of eliminating fatal accidents is even easier to visualise, he added.

Another helicopter safety project of the NMCAD Lab that Viola was curious about was improvement in fatigue life and/or performance of main rotor blades through three out-of-the-box ideas, individually and in synergy, said Prof Harursampath.

“According to James, these technologies would go a long way in achieving the zero-accident vision of the International Helicopter Safety Team (IHST) of which India, the US and Canada are integral parts,” he added.

This is just an upgrade - that is existing ones are going to be upgraded rather than junking them. I think there is a huge expansion in the type and variety of air defence artillery we need and there is probably some place for these upgraded guns - in situations that do not call for more modern systems. I suspect that older/upgraded air defence guns will be placed around less vulnerable targets like Sonia Gandhi's house or Governor's bungalow, Bengaluru Kerala. They can also be used against ground targets I think.
