Reliance arm buys 51.78% stake in Asteria Aerospace.

Reliance Industries on Friday said its wholly-owned subsidiary Reliance Strategic Business Ventures Ltd (RSBVL) has acquired over 51 per cent stake in Asteria Aerospace for Rs 23.12 crore.

"RSBVL has acquired equity shares of Asteria Aerospace for a cash consideration of Rs 23,12,49,584. The said investment represents 51.78 per cent holding in the equity share capital of Asteria," Reliance Industries Ltd (RIL) said in a BSE filing.

The investment will further enable the group's initiatives in emerging technology, it added. RSBVL proposes to make a further investment of up to Rs 125 crore, subject to Asteria achieving agreed milestones, and is expected to be completed by December 2021, it said.

"Post the further investment, the shareholding of RSBVL will increase to 87.3 per cent of the equity share capital of Asteria," it added. On Thursday, RSBVL had said it has picked up 85 per cent stake in NowFloats Technologies for a cash consideration of Rs 141.63 crore.

Asteria, incorporated in India in June 2011, is a full-stack drone technology company with in-house drone manufacturing capabilities, and also offers software solutions to provide actionable insights from aerial data, intending to deliver "drone-as-a-service" digital platform.

There are people who want fully-baked solutions to what the armed forces require, rather than take what can be made at present and get involved in a better iteration, the Navy is the best example of what can be done ( LCA for eg)

Just figured out that OFB does not even list 125/120 MM Sabot rounds under it's products list! Fundamentally no production of sabots..

Looks like an entire unit (HAPP) is sitting on it's backside.. enjoying holidays.

The screw ups done by OFB in sabot production, coupled with our armor boys disinterest has created a royal mess.

All sabots seems to be imports.

Bharat Forge increases stake in defense tech supplier Aeron Systems.

Automotive and defense supplier Bharat Forge on Monday increased its stake in aerospace and defense technology supplier Aeron Systems in its bid to increase its know-how in the defense technology.

Aeron Systems manufactures technology products for sectors like aerospace and defense, automotive, renewable energy and industry 4.0. In May this year, Bharat Forge had announced its interest in the company to gain access to technologies in the defense and aerospace sectors.

The company has so far invested around Rs 8 crore in Aeron to acquire 78,000 shares. It will further invest around Rs 2 crore to acquire an eventual 26% stake.

Bharat Forge has also invested in companies like UK-based Tevva and Pune-based electric motorcycle startup Tork Motors, which is yet to sell its maiden product, to acquire new-age technologies.

In an interview with ET, Baba Kalyani, chairman of Bharat Forge, had said that the company is doing considerable work in the areas of defense, electric vehicles, nanotechnology and composites, including carbon composites.(Indicates plans to get into new areas of military equipment business)

The industry is moving away from being centred around metals towards other materials and electronics, for which the company is gearing up, Kalyani had said.

The armed forces set pretty restrictive standard in 2013 RFP. I read an interview of SMPP owner where one size of their three sizes of jacket failed on 395th round being fired at it. The army cut off was 397 rounds. Most manufacturers couldn't make it past 20 bullets. That process resulted in zero bidders qualifying.

Because we don't have a BPJ that can withstand the 397th bullet,
We will not induct any BPJ, that can withstand 20 bullets,
But I will get on my high horse and proclaim: "We will fight with what we have", while letting my boys die

We had decades like these. Just wow!

PM to dedicate Five DRDO Young Scientists Laboratories to the nation
Posting in fulll...

In a boost to indigenous research capabilities in the defence sector, Prime Minister Shri Narendra Modi will dedicate Five DRDO Young Scientists Laboratories to the nation on Thursday January 2, 2020.

The event shall be organised at the Aeronautical Development Establishment, DRDO at Bengaluru. Prime Minister shall unveil a plaque to mark the dedication, and address the Scientists.

DRDO will also showcase some of its innovative products to the Prime Minister at an Exhibition on the occasion.

Chief Minister B. S. Yediyurappa and DRDO Chairman Dr. G Satheesh Reddy will be present on the occasion.

It may be recalled that in 2014, addressing a distinguished gathering of senior and eminent defence scientists, and senior officers of the armed forces, after giving away the Defence Research and Development Organization (DRDO) awards, the Prime Minister had suggested that at least five DRDO labs should be identified exclusively for innovation from young scientists upto the age of 35 years.

On that occasion, the Prime Minister had also called for involving youth in defence research related activities in a big way, to ensure that India remained abreast of global technological advancements in the field.


I heard (might be rumors) that NaMo is scheduled to visit Tumkur on Jan 3rd related to some HAL activity. Could get an announcement regarding Ka-226 assy plant...have to wait and see

Defence PSUs have unfair advantage: SIDM

Issues over a level playing field with government-owned enterprises still remain, according to the Society of Indian Defence Manufacturers (SIDM), which has expressed concern over increasing military imports and declining modernisation budget for the armed forces.

SIDM president Jayant D Patil told ETthat it would be impossible for the private industry to compete with public sector units (PSUs), which have access to low interest capital, fixed infrastructure and manpower. He said government investments in PSUs should be taken into account and added to the cost of a product for competitive bids. “The fact is that government-owned assets provided to PSUs have to be at some point taken to book. A sizeable amount of money has gone into creating these enterprises; this has to be measured. The moment it is brought to book, the PSUs will need to provide the extra cost (while bidding),” said Patil, who is also a Larsen and Toubro board member.

He said that unless the costs are accounted for, private industry will not be able to compete against government-owned units like Hindustan Aeronautics Limited that have been getting nominated orders from the forces for decades.

Patil, who recently took over as the SIDM president, raised concern over an increase in imports of defence equipment over the past few years which had reduced the share in the pie for the Indian industry. “We saw that through policy changes, the domination of imports had started reducing.

However, over the last two years or so, imports are increasing again,” said Patil. “The situation we had been getting used to was that 60-70% orders were placed with PSUs and 30-35% with overseas companies. But what we have now seen is that 65%of contracts actually signed were with foreign companies.” He said the actual import percentage could be even higher as the domestic products too could have components and parts that have to be sourced from abroad.

Patil said there has been concern in the industry over a deficient defence modernisation budget that could impact procurement plans. “Earlier, the spending on defence was 2.8% or more of the GDP. Today we are down to 1.6%. We can say that the GDP has grown, but the fact is that the cost of equipment has also gone up,” he said.

The industry has shared its concerns with the parliamentary standing committee on defence, which has expressed shock over a lack of funds being allocated to the forces and said that the international image of the country can come under question if committed liabilities are not paid off due to the inadequate budget.

“The committee finds the shortage baffling, as these are the payments towards procurements already done in previous years. The committee feel that making the country defaulter in payment will not go well in the international markets, therefore, they recommend that allocation as promised should be disbursed for committed liabilities,” said a report of the standing committee tabled in Parliament last month.

Wipro, HAL in pact to make 3D-printed aircraft parts

Bengaluru: Hindustan Aeronautics (HAL) and WiproNSE 1.47 % 3D, the metaladditive manufacturing business of Wipro Infrastructure Engineering, have partnered to develop 3D-printed components that could potentially be used on aircraft manufactured by state-run HALNSE -0.05 %.

Wipro 3D is the first Indian company to locally develop an industry-grade metal-additive 3D-printing machine, jointly with the Indian Institution of Science. As part of the memorandum of understanding, HAL and Wipro 3D will jointly design, develop, prove out, manufacture and repair aerospace components using metal 3D- printing technology.

“This initiative between HAL and Wipro 3D will create a unique synergy of capabilities that can accelerate the adoption of metal additive manufacturing in aerospace in India. Qualification of parts for aerospace is challenging as it would require prove out and extensive testing followed by certification by regulatory authorities which may also include flight testing.

An old patent for a intense light source.

https://patents.google.com/patent/US862 ... oq=8621999

A version could be used to disrupt laser guided munitions for important target like hangers etc.
A sensor could be programmed to initiate this when it senses a laser from hostile aircraft.
Basically its an anti-laser ERW type defensive measure.

Another missile tracking ship pops up! Spotted a radar frame on the TDV-
Image
Image
With Vikrant getting all the attention, the TDV was conveniently ignored. I received these pics today and I was surprised to see a weird structure (pointed by a red arrow). It's clearly a support structure of a radar array i.e. this is where the antenna of radar goes. It's significantly larger than the two similar structures present on the Vikrant, also visible in both pictures. While it's clear that it's a radar ship, the presence of A-frame indicates that this ship could be stationed downrange to assist debris recovery. Dr.Y.Srinivasa Rao is the project director of 'Ship No. 20', he is scientist-G at Research Centre Immarath, DRDO, Hyderabad. He is also associated with Program AD (PGAD) i.e. Indian BMD.

"All is Not Well ..Not Yet "


From Janes.,


An enduring resource crunch and increasingly complex acquisition procedures have curtailed India’s long-delayed military modernisation as its armed forces face pressure in their immediate neighbourhood. Rahul Bedi reports India’s senior service officers say that acute platform, ordnance and munitions shortages are hurting the military’s operational deployment on counter-insurgency (COIN) operations along the disputed borders with China and Pakistan, as well as hampering preparations for potential conflict
with either or both of those nuclear rivals. Contracts for urgently needed combat, transport, basic trainer, and tanker aircraft; helicopters; submarines; minesweepers; main battle tanks (MBTs); infantry combat vehicles (ICVs); various small arms; and other equipment are either pending or have been scrapped after extended evaluations, trials, and price negotiations. The Indian Ministry of Defence’s (MoD’s) continuing fiscal crisis is also leading to postponed payments to materiel vendors for previously obtained and underacquisition equipment, according to industry sources, and in late December a parliamentary defence committee criticised the government for defaulting on payments.

“Delayed procurement of warfighting equipment has weakened [India] operationally and compromised our strategic independence,” said military analyst Lieutenant General (retd) P R
Shankar. Over the past five years India has prioritised indigenous development and manufacturing of military equipment by involving private manufacturers under its ‘Make in India’ initiative, aiming to reduce materiel imports. However, progress has been dismal, with imports still accounting for 60–65% of all Indian military acquisitions. The MoD informed parliament in November 2019 that India had imported defence equipment and services worth INR1.62 trillion (USD23 billion) in 2014–19. Defence officials said these imports,
primarily from France and the United States, included 22 Apache AH-64E(I) Guardian attack helicopters and 15 Chinook CH-47F heavylift helicopters from Boeing for USD3.12 billion and 36 Rafale fighters for EUR7.9 billion (USD8.8 billion) from Dassault for the Indian Air Force (IAF). Other major imports included four Boeing P-8I Neptune long-range maritime multimission aircraft for USD1.1 billion for the Indian Navy (IN) and 145 BAE Systems M777 155 mm/39 cal lightweight howitzers costing USD737 million for the Indian Army (IA). Several deals were also being signed with Israel and Russia or were in advanced stages of negotiation, officials said. However, senior defence planners contend that a large proportion of these purchases via the US Foreign Military Sales (FMS) process, along with an intergovernmental agreement with France, were “haphazard and ad hoc”. According to Amit Cowshish, a former MoD financial advisor for acquisitions, it was unclear whether the ministry had augmented the country’s defence capability by securing those purchases and guarded against default on future purchases and contractual payments

Many programmes to design platforms and equipment under the government-run Defence Research and Development Organisation (DRDO) have been jeopardised by budget cuts, delays, technical challenges, and cost overruns. Private-sector involvement in expanding India’s defenceindustrial base has also been limited, with the MoD continuing to favour the country’s nine defence public sector units (DPSUs) and 41 state-run Ordnance Factory Board (OFB) entities in awarding tenders.
The MoD also told parliament in late 2019 that between 2014 and September 2019 its Defence Acquisition Council (DAC) approved 218 acceptances of necessity (AoN) proposals worth more than INR4 trillion to promote domestic manufacturing, without providing further details. Industry officials told Jane’s that over the years almost all these AoN clearances lapsed, since no tenders had been issued for any of them within 6 and 12 months of approval, as stipulated by successive editions of the Defence Procurement Procedure (DPP) manual. “A large proportion of AoNs routinely fade into oblivion, with just a handful being subsequently revived,” said a two-star Indian Army (IA) officer, declining to be identified. Securing AoNs, he said, is no more than a “bureaucratic manoeuvre” by the MoD to show its intent.
Analysts said steadily declining defence budgets have compelled all three services to limit their equipment requirements, rationalise expenditure, and retain platforms such as the MiG-21 and MiG-27 variant fighters and Hindustan Aeronautics Limited (HAL) licence-built Chetak (Aerospatiale Alouette III) and Cheetah (Aerospatiale SA 315B) light utility helicopters (LUHs) in service well beyond their official lifespans.
The situation has also led to India’s Cabinet Committee on Security, which is headed by Prime Minister Narendra Modi, deferring final acquisition and financial authorisations for several MoDapproved procurements in recent months. Military sources said these included the INR135 billion acquisition of 24 Sikorsky MH-60R Seahawk multirole naval helicopters and 30 armed multimission General Atomics Aeronautical Systems Inc (GA-ASI) Guardian unmanned aerial vehicles (UAVs) for about USD2 billion through the FMS process.

Smart bombs, futuristic combat vehicle in pipeline: OFB head.

Ordnance factories were also planning to manufacture `smart bombs' or guided artillery ammunition rounds of 81mm, 51mm, 120mm and 130mm caliber, he informed.


A "Futuristic Infantry Combat Vehicle" for the Indian Army was also in the works, he added.

"OFB started manufacturing Armoured Personal Carriers for the army from 1983-84. But now the OFB has developed its own Futuristic Infantry Combat (FIC) Vehicle for the army," he said.

"It is almost 85 percent ready. In coming months the FIC will be fully ready and exhibited in the next Defence exhibition," Mohan added.

2022, is my guess.

Simple way to figure out the guidance kit stuff is to see if a similar portfolio exists for some Euro or Yahudi or Russkie firm. That's likely the source of TOT. Until and unless I am badly mistaken and they have a tie up with ARDE to make something similar locally.

OFB participating in FICV is such a nonsense. If OFB is in the fray, the private companies cannot get orders. What is the point of participating?

If a private company prototype is chosen, will they allow OFB to built it?

South Korea is to buy two more Green Pine early warning missile defense radar systems from Israel Aerospace Industries Ltd. (IAI) (TASE: ARSP.B1) unit ELTA, the country's Defense Acquisition Program Administration (DAPA) procurement agency has reported. The deal is worth $292 million.

The improved Block C radar systems have a detection range of up to 800 kilometers compared with the 600 kilometer detection range of the systems deployed by the South Korean military back in 2009. Reports from South Korea say that the new systems will be delivered and deployed in the early 2020s.

The new system will be able to, "identify and track ballistic missiles from a remote distance shortly after launch," the DAPA said.


Assuming target RCS is the same as mentioned for the LRTR, this indicates the original desi LRTR variant was roughly equal to the improved Green Pine Block B aka Super Green Pine introduced by Israel only in 2012-13. And the current improved LRTR, is analogous to the Block-C.

Not at all. Completely different classes of systems. LRTR is (relatively) high grade surveillance and fire control, backed up by MFCR for even more precise fire control. OTH is basically going to have far less resolution. It will serve as an initial EW sensor to direct other higher precision sensors towards important targets.

South Korea is to buy two more Green Pine early warning missile defense radar systems from Israel Aerospace Industries Ltd. (IAI) (TASE: ARSP.B1) unit ELTA, the country's Defense Acquisition Program Administration (DAPA) procurement agency has reported. The deal is worth $292 million.

The improved Block C radar systems have a detection range of up to 800 kilometers compared with the 600 kilometer detection range of the systems deployed by the South Korean military back in 2009. Reports from South Korea say that the new systems will be delivered and deployed in the early 2020s.

The new system will be able to, "identify and track ballistic missiles from a remote distance shortly after launch," the DAPA said.


Assuming target RCS is the same as mentioned for the LRTR, this indicates the original desi LRTR variant was roughly equal to the improved Green Pine Block B aka Super Green Pine introduced by Israel only in 2012-13. And the current improved LRTR, is analogous to the Block-C.


There were indeed reports of the "Swordfish" radar ranging more than 800 km

Wiki mentions DRDO testing new versions ranging out to 1500 km way back in 2012 , we may not know the exact status of such advanced variants

OTH radar resolutions have been much refined from its beginnings as in Australias Jindalee that ranges out to 3000 km. BAE upgrades to the hardware and software permits much higher resolution and data processing, with exact "new capabilities" classified.

Points to note " JORN uses the Doppler principle to detect objects, it cannot detect objects moving at a tangent to the system, or objects moving at a similar speed to their surroundings"

The JORN network is operated by No. 1 Remote Sensor Unit (1RSU). Data from the JORN sites is fed to the JORN Coordination Centre at RAAF Base Edinburgh where it is passed on to other agencies and military units. Officially the system allows the Australian Defence Force to observe air and sea activity north of Australia to distances up to 4000 km.[26] This encompasses all of Java, Irian Jaya, Papua New Guinea and the Solomon Islands, and may include Singapore.[27] However, in 1997, the prototype was able to detect missile launches by China[28] over 5,500 kilometres (3,400 mi) away.

JORN is so sensitive it is able to track planes as small as a Cessna 172 taking off and landing in East Timor 2600 km away. Current research is anticipated to increase its sensitivity by a factor of ten beyond this level.[citation needed]

It is also reportedly able to detect stealth aircraft, as typically these are designed only to avoid detection by microwave radar.Project DUNDEE was a cooperative research project, with American missile defence research, into using JORN to detect missiles. The JORN was anticipated to play a role in future Missile Defense Agency initiatives, detecting and tracking missile launches in Asia.

As JORN is reliant on the interaction of signals with the ionosphere ('bouncing'), disturbances in the ionosphere adversely affect performance. The most significant factor influencing this is solar changes, which include sunrise, sunset and solar disturbances. The effectiveness of JORN is also reduced by extreme weather, including lightning and rough seas.

As JORN uses the Doppler principle to detect objects, it cannot detect objects moving at a tangent to the system, or objects moving at a similar speed to their surroundings

Kit, nothing in that Wiki excerpt says the range resolution of a JORN type setup can match what we require from a LRTR for a fire control solution. The missiles onboard seeker is for terminal guidance not for doing a wide area search and locating a target in a cell many many kilometers wide.

So, my understanding is that typical OTH radars work by bouncing signals off the ionosphere. This means they necessarily use low frequencies - in the HF range and below (google for "critical frequency" and "maximum usable frequency").

This means it is pretty much unreliable to detect objects in near space - such as ballistic missiles before re-entry and satellites (if you want to do ASAT).
And because ionosphere bounce is pretty unreliable, and reflected signals can also bounce off, I'm also not sure how very good directivity is achieved, unless they use multiple yagi receivers scattered over a huge area. So, it means it is really hard to do tracking.
This also means each antenna element is really big (100 times larger compared to L-band for instance), they need large installations.

Didn't have to wait for this one, the radar was revealed back in 2018 :D
