Integrated Weapons System Design Centre Opened In Hyderabad.

Vice-President M.Venkaiah Naidu inaugurated the Integrated Weapons System Design Centre at DRDO’s APJ Abdul Kalam Missile Complex here on Monday.

The facility would enhance the capability in design and development of command and control systems for surface-to-air missile (SAM) systems and ballistic missile defence (BMD) systems, said Defence Research and Development Organisation (DRDO).

The DRDO officials explained that the centre would give thrust to the overall system design and evaluation methodology for state-of-the-art missile systems and would help in improving the performance of missiles.

This would play a major role in the realisation of highly complex futuristic aerospace and defence systems.

The DRDO officials briefed Naidu on the various ongoing projects and technological developments of missile complex laboratories — Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI).

He also showcased a range of indigenously developed missile systems and avionics technologies.The Vice-President evinced keen interest in DRDO technologies and various test facilities being used for advanced technology developments.

Addressing the DRDO fraternity, he complimented the scientists for their hard work and dedication even during the nationwide lockdown and said the efforts by DRDO have led to the phenomenal technological advancements in the form of a series of successful missions such as HSTDV, SMART, ATGM, NGARM, HELINA, NAG, BRAHMOS etc.

He mentioned that the DRDO is an epitome and torchbearer of scientific social responsibility and is a place of eternal learning.The role played by the DRDO during the pandemic has set an example for others to emulate.

He said that the development of a range of indigenous defence systems by DRDO has given confidence to the Indian government for banning import of 101 items.

Remembering former President Kalam, Naidu said the scientific institutions of the country should never work in the incremental mode.He praised the scientists for maintaining the legacy of Kalam and encouraged the scientific community to continuously attempt to leapfrog in scientific endeavours.

He said Kalam wanted India to become a superpower and mentioned that the scientists have the calibre to make “Atmanirbhar Bharat”.He said it is important to hold hands of young techno-preneurs, industries, academia, guide them and move together to build a strong and technologically superior country.

We have made commendable achievements in missiles and hoped that by doing so we might become top exporter in the field of missiles, he added.
Naidu also inaugurated a new missile technology exposition and seminar hall in the same campus.

The exposition would display missile technologies and weapon systems and the centre would be the backbone for outreach activities.This hall is a part of knowledge management initiatives taken up by the Missile Complex to provide an interactive platform for continuous learning and fostering technical excellence among the missile community.

It would be a hub for organising scientific expositions, structured training programmes on virtual platforms and technical lectures for the benefit of DRDO community.

The Vice-President commended the work being done by DRDO under the dynamic leadership of G.Satheesh Reddy, Secretary, Department of Defence R&D, and Chairman DRDO.M.S.R.Prasad, Director General, Missiles and Strategic Systems, was also present during the visit and explained about the various missile technologies.

Per a AV on this occasion a new strategic air to ground system was displayed that will be used to target enemy underground facilities as well as command centers and ammunition depo's.

DRDO'S LAND BASED AIP SYSTEM DEMONSTRATES 14 DAYS OF CONTINUOUS OPERATION.

DRDO's Land Based prototype of Air Independent Propulsion System (AIPS) has demonstrated 14 Days of continuous operation as per a media report. Marking the crucial step towards it's usage. AIP plug in Scorpene submarines would boost operational capabilities.

Air-Independent Propulsion (AIP)

A submarine’s Air-independent Propulsion (AIP) system ensures operations of the conventionally powered submarine to operate without the need for outside air. A Kalvari Class submarine when fitted with an AIP system onboard shall be able to run its electric propulsion motor and electrical network with the conventional batteries bypassed. This benefit reduces the need for the submarine to surface often to take in the air for running diesel engines (for battery charging). The Kalvari class submarines are powered by conventional diesel-electric propulsion systems, and as per the original plans, the last two submarines were to be equipped with an indigenously developed AIP technology. This state of the art Fuel-cell based AIP is to be indigenously designed by DRDO since such technology from abroad is expensive.

Despite the commissioning of the first two submarines, DRDO has been unable to meet the timelines of the AIP development, which is still at a land-based laboratory. The rest of the four P75 submarines are scheduled for commissioning by 2022. Presently, the indigenous AIP system is planned to be a retrofit onboard first submarine, as and when it enters a major Refit.

India’s Kalvari Class Submarines

Under the P75 Project, six Kalvari class (Scorpene) diesel-electric attack submarines (SSKs) construction is in progress at Mazagon Dock Limited (MDL), with technical support in terms of technology transfer (ToT) contracted with French Naval Group (former DCNS). Kalvari class are advance conventional propulsion stealth attack submarines designed for longer ranges while being submerged and have advance design features like very low acoustic, electromagnetic and infrared(IR) signatures. Two of these submarines have since been commissioned by Indian Navy.

A Compromised Silence Underwater

As per the OEM, Naval Group, there are two variants of `Scorpene’, the conventional propulsion system and, another one equipped with AIP. The AIP enabled submarine has a distinctive advantage over conventional propulsion, with these capable of remaining submerged on underwater patrol for three times longer. This is a huge difference when it comes to any underwater sea battle and is a game-changer. The very detection of a submarine which needs to surface even up to snorkelling depth with today’s advanced aerial technology onboard maritime patrol aircraft can be sure given away. Further, the stealth is the primary weapon of any submarine on surveillance or an attack mission.

According to a senior officer who wished to remain anonymous, “An Indian submarine lacking a AIP capability is likely to be at a huge disadvantage over an AIP fitted Chinese or Pakistani submarine. AIP enabled submarines lurking underwater, can make a silent and undetected approach close to a warship or submarine, and launch a torpedo attack with a better probability of kill. This makes protection of capital ships within a Fleet Task Force highly vulnerable simply because of the hostile submarine is already elusive and can approach its torpedo firing range before being detected or engaged by even by the latest P-8I multi-role maritime patrol aircraft.”

Significance of Tracking Other Nations’ Assets

World over, tracking of ships and submarines of non-friendly nations in international waters is a vigorously exercised option for various reasons. Such activities had reached a heightened level during the cold war era. US maritime patrol warships and aircraft regularly dropped sonar buoys to track Soviet submarine. The aim of such manoeuvres usually involves the collection of unique electromagnetic (EM) and acoustic signatures of the ships and submarines so as to update or append the Electronic Warfare (EW) library. And this helps in easy identification of the target in future.

Scorpene submerged range is1020 km @5knots(9.3kmph) i.e, 4.56days.
240t battery weight gives roughly 10MW hr storage capacity.
If DRDO AIP is at full capacity run for 14 days @250 kw per hour then is 84MW hr capacity i.e, 8.4 times the battery capacity.
Total distance traveled on both will be 9588 km and endurance will be 43 days @9.3km per hour.
This is on assumption that AIP capacity is 14 days on full power of 250kw/hr.

In a first, Tata to build military aircraft in India as it acquires IP rights.

In a first for the industry, the Tata Group will develop and manufacture a military aircraft in India, having acquired intellectual property rights for a German-origin platform. The plan, ET has reliably learnt, is to integrate indigenous sensors and payloads to convert it into an intelligence gathering asset.

The high-altitude, twin-engine aircraft, capable of playing multiple roles from signal intelligence to cross-border surveillance, is currently in the final stages of testing in Germany. It is likely to arrive in India in the next three months for further integration.

This would be the first time that an Indian private entity is looking at making a full military-grade aircraft, which until now has been the domain of the state owned Hindustan Aeronautics .

Tata Advanced Systems (TASL) will showcase the capabilities of the aircraft at the Aero India in Bengaluru next week. Though the company has not shared details of the design, the aircraft is likely to be based on the Grob G 180 SPn – a German made jet that never reached serial production due to financial strains.

Image

TASL is yet to get any confirm orders for the aircraft in India, but top executives say the investment has been done keeping in mind future requirements of the armed forces. A manufacturing plant will be set up for serial production in the future, they added.

The company sources said the aircraft it is developing is designed for flying at 41,000 feet altitude with a maximum altitude of 45,000 feet and can be used for intelligence gathering, surveillance and reconnaissance (ISR) purposes. It is designed to land on grass and gravel. The low-wing, twin-engine composite aircraft is expected to have a range of 1800 nautical miles and 6-7 hours endurance with a payload capacity in excess of 1,000 kg.

“We are now focusing on modifying the aircraft to t special payloads so that it can undertake a demonstration of surveillance capabilities. For a country like India, with multiple mountain ranges spread across the country, including on international borders, this capacity is extremely vital. India has been dependent on foreign suppliers to meet this need,” said Sukaran Singh, MD of TASL.

He added that acquiring such technology will enable India to modify and t any payloads it wants within the country, reducing dependence on foreign suppliers. “With TASL bringing this aircraft technology to the table, India will have a cutting edge air-borne surveillance platform, with control over the software, customisation as well as maintenance, based within the country,” he said.

The need for effective border surveillance has been a focus after recent tensions with China in Ladakh.

With nod for 83 LCAs worth RS 47k-cr, HAL readies 3rd plant.

Buoyed by the recent Cabinet Committee on Security (CCS) approval for procurement of 83 Light Combat Aircraft (LCA) Tejas Mark-1A aircraft
worth Rs 47,000 crore, Defence PSU Hindustan Aeronautics Limited is all geared up to make operational a dedicated second LCA plant in Bengaluru.

The new plant at Doddanekundi here, according to sources in HAL, will be inaugurated by defence minister Rajnath Singh on Tuesday. “The plant,
when commissioned fully, will be able to produce 16 LCAs per year. We’ll make the Tejas Mark-1A and the trainers here,” one source said.

At present, HAL has the capacity to manufacture eight LCAs per year. The first dedicated LCA plant and HAL’s Aircraft IAF's Light Combat Aircraft
Division are both producing them. “The plant that will be inaugurated by the defence minister will technically be the third, given that the Aircraft Division also make LCAs now,” the source said.

(so 16 a year in new plant + 8 in the old plant. HAL is also planning for a capacity of 8 a year in Nashik plant to cater to likely export orders , Total comes to 32 in a year :shock: and I am not even counting the make shift assembly capacity at old Kiran Hangar).


The Tejas Mark-1A aircraft worth Rs 46,898 crore - 73 fighters and 10 trainers - cleared by the CCS on January 13, will have 43 “improvements” over the Tejas Mark-1 jets which the IAF has already placed orders for earlier.

The order/contract for the new 83 aircraft is expected to be placed during the upcoming Aero India show. “From the date of the signing of the contract, HAL will have 36 months to start delivering the rst batch of aircraft,” the source said.

There was no immediate conrmation on the investment that has gone into the second plant, or when it is expected to be commissioned fully. “The rst phase of the operations will start in a few months after Tuesday’s inauguration and we’ll subsequently commission the rest of the plant,” another source said, adding that existing manpower will be used to operate the plant.

Soon after the CCS nod, HAL had said: “Tejas would have the highest level indigenisation in comparison to any programme of this scale with progressive indigenisation of critical technologies, thereby making India a technologically self-reliant nation. The programme would look at developing technologies indigenously.”

The Tejas programme, the PSU said, has created a national aerospace ecosystem with participation of approximately 560 companies. “It is estimated that as the LCA Mark-1A programme kicks-o, it will generate primary jobs to a tune of 5,000 across the country. The programme will foster local industry and drive skill development of young Indian workforce,” HAL said.

As per the PSUs estimates, the LCA programme, till date has produced 50,000 primary and secondary jobs across the nation. “For the first time in India’s aerospace history, the program enabled partnership with Indian private players to manufacture aircraft fuselage and wings. Some of the major companies contributing in the programme from the private sector are VEM technologies, L&T, DTL, Alpha Toccol, TAML, Data Patterns, Pendios, Compupower and many others,” HAL added

We should have created air launched CM using PTA engine long while back. It is only now IAF seems to be waking up for the need of longer range standoff weapon.

Otherwise it was only Spice and TFTA dreams of Scalp. The obsession with Rafale or nothing has blocked every program..

It would be wise to focus on the medium range (500-800 km) capability with the subsonic-ALCM and then look to go into longer ranges. Particularly with the diversity of platforms ranging from the LCA on one end of the spectrum and the MKI on the other.

Looking at all the tech development happening., it is rather stupid for any country to offer legacy platforms to India hoping that would sell !!
Really hope to see such tech evolution happen in case of the Navy too, embracing startups and new tech !
The Army seems to be getting it hope we see more in the case for APCs and innovative Tank/missile platforms !

HAL and MIDHANI sign MoU to develop composite raw materials.

Hindustan Aeronautics Limited (HAL) and Mishra Dhatu Nigam Limited (MIDHANI) have signed a Memorandum of Understanding (MoU) for development and production of composite raw materials during the Aero India 2021 in Bengaluru on February 04, 2021. This is the first time that such an MoU has been signed for composite raw materials. The MoU was signed by Chairman and Managing Director, HAL Shri R Madhavan and Chairman and Managing Director, MIDHANI Dr S K Jha in the presence of other senior officials.

Mr R Madhavan said composites are one area where HAL will collaborate. Composites raw materials, mainly in the form of prepregs used in platforms like Light Combat Aircraft (LCA), Advanced Light Helicopter (ALH), Light Combat Helicopter (LCH) and Light Utility Helicopter (LUH) are currently imported.

The CMD of MIDHANI Shri S K Jha said this is the major step forward in the area of composite materials. The HAL is not only taking care of frontline aircraft production but also raw materials. There is no equivalent proven Indian approved/qualified supplier for various types of prepregs (carbon, aramid, glass types, etc) for the aircraft applications. This creates a dependency on foreign Original Equipment Manufacturers (OEMs). Aligned with "Atmanirbhar Bharat" initiative, efforts need to be made to develop and manufacture such prepregs in India through collaboration, he added.

The usage of composites in the aerospace is going to exist and increase, particularly for fighter aircraft/helicopter because of its inherent advantages over metallic raw materials. In addition, a similar requirement exists for other aerospace and defence programmes, including those of Indian Space Research Organisation (ISRO), Defence Research Development Organisation (DRDO) and National Aerospace Laboratories (NAL).
