Indian Laser and Directed Energy Weapon (DEW) Thread

[Indx TechStyle]

LASTEC has designed and developed a laser warning and countermeasure system for Armoured Fighting Vehicle (AFVs). A LWS is capable of handling multiple type of laser threats and has an operational range of more than 6 km for laser designator type of laser threat. After detecting the laser threat along with its direction, it also has the capability to generate trigger signal to activate the grenade launcher for firing of smoke grenade in the direction of laser threat to obscure the platform under threat. Technology of the LWS has been transferred to BEL, Pune.

The laser warning sensors detects the laser radiation processes, determine the PRF and edge matching signals. It comprises of opto-electronic front end, signal processing and conditioning, embedded module for PRF decoding, and edge matching signal.

The master controller receive inputs from multiple laser warning sensors, processes the information and feeds the desired commands to the decoy laser. The master controller comprises of hardware and software module to interface with the laser sensor units and the decoy laser.

Decoy laser is a high energy laser source that takes command from laser warning system and generate a pulsed laser radiation synchronised with the PRF generated by the laser warning system. It is used to illuminate a dummy target to misguide the laser guided bomb on to the dummy target.

The homemade helicopter LWS must be at late stages as well.

'Laser walls' activated along India-Pakistan border to plug gaps in vigil

The 'laser walls' are armed with night and fog operability tools
HIGHLIGHTS
• The decision to install 'laser walls' taken by BSF 2 years ago

• They will help guard areas where barbed wire fencing can't be installed due to treacherous terrain

• Satellite-based signal command system used for montoring; these walls armed with fog operability tools

NEW DELHI: A dozen "laser walls" have been made operational along the India-Pakistan international border in Punjab to plug the porous riverine and treacherous terrain and keep an effective vigil against intruders and terrorists exploiting the frontier areas to cross over.

While eight infra-red and laser beam intrusion detection systems are "up and working" along as many vulnerable and sensitive areas of the international border (IB) in Punjab, four more will be operationalised in the next few days, a senior official of the Border Security Force (BSF) said.

The "laser walls" or fence are being monitored by the BSF which guards the Indo-Pak border in Jammu and Kashmir, Punjab, Rajasthan and Gujarat.

The decision to install these laser walls was taken by the BSF two years ago keeping in mind the vulnerability of the border in these areas as barbed wire fencing could not be installed in many infiltration prone areas due to treacherous terrain or marshy riverine topography.

After the Pathankot terror attack, where it was suspected that terrorists crossed over from Pakistan by breaching the border from Bamiyal area in Punjab, Union home ministry and BSF sped up the deployment and activation of these walls along the long and winding border.

A total of 45 such laser walls will be installed in these areas along the international border in Punjab and Jammu, a blueprint prepared in this regard and accessed by PTI said.

According to the blueprint, the BSF along with a team of technical experts will be conducting a pilot project for deploying "technological solutions" for effective border guarding at two "sensitive" riverine stretches in Jammu sector which entails deployment of smart sensors to pick up suspected movements along the international border.

"The laser walls have started working and their functioning is being monitored. Preliminary results in detecting illegal movements are encouraging," the official said.

He said sensors were being monitored through a satellite-based signal command system and armed with night and fog operability tools.

Apart from these, four other pilot projects of similar kind in stretches of 30-40 kms of international border in Jammu and Gujarat and one in West Bengal along Indo-Bangla border have been approved by Home Ministry to secure Indian borders effectively.

"Work on them will begin by next month," he said.
After the Pathankot incident, BSF had deployed an additional battalion (about 1,000 men) in Punjab sector even as it has increased the number of its ambush operations and patrol in the area.

The BSF is also considering deploying at least four more battalions in Punjab and Jammu border areas as a second-tier of defence after withdrawing these units from the Line of Control.

Probably, US has already in operation, China is about to operationlize. By 2025-30, we could match both of them in military aspects(except Air Force).
So, this project can be proved a boon for our AF.

Yup. Operationalized and deployed on all their expeditionary ships.

Had posted everything got except wiki.
So here's.
Laser Science & Technology Centre (LASTEC)
DRDO is working on a slew of directed energy weapons (DEWs). LASTEC has identified DEWs, along with space security, cyber-security and hypersonic vehicles as focus areas in the next 15 years.[45] The aim is to develop laser-based weapons, deployed on airborne as well as seaborne platforms, which can intercept missiles soon after they are launched towards India in the boost phase itself. These will be part of the ballistic missile defence system being currently developed by DRDO. LASTEC is developing a 25-kilowatt laser system to hit a missile during its terminal phase at a distance of 5–7 km. LASTEC is also working on a vehicle-mounted gas dynamic laser-based DEW system, under project Aditya, which should be ready in three years. Project Aditya is a technology demonstrator to prove beam control technology. Ultimately, solid-state lasers would be used.

LASTEC projects include:


Hand-held laser dazzler.
Non-Lethal systems:

• Hand-held laser dazzler to disorient adversaries, without collateral damage. 50-metre range. Status: Ready.
• Crowd-control dazzlers mounted on vehicles to dispel rioting mobs. 250-metre range. Status: Will take 2 more years.
• Laser-based ordnance disposal system, which can be used to neutralise IEDs and other explosives from a distance. Status: Trials begin in 18 months.

Lethal Systems:

• Air defence dazzlers to take on enemy aircraft and helicopters at range of 10 km. Status: Will take 2 more years.
• 25-kilowatt laser systems to destroy missiles during their terminal phase at range of 5 to 7 km. Status: Will take 5 more years.
• At least 100-kilowatt solid-state laser systems, mounted on aircraft and ships, to destroy missiles in their boost phase itself. Status: Will take a decade.

Indian Navy eyes Directed Energy Weapons (DEW)

Indian Navy plans for its Future warships in next decade or so will see the incorporation of two revolutionary fitments : integrated mast housing L-,S- and X-band active phased-array radars and Directed Energy Weapons (DEW) effectors on warships which are still on drawing boards and on their follow-up designs. DEW effectors primarily to be used as a self-defence weapon system against Uav’s, Incoming sea skimming anti-ship missiles or subsonic cruise missiles.

Research and Development on DEW for warships worldwide has already spawned several solutions that are now undergoing sea-trials and will see the incorporation of DEWs soon in many frontline warships while India is seriously lacking behind in this category but DEWs are one of the priorities projects which DRDO plans to focus next.

DRDO’s Laser Science & Technology Centre (LASTEC) been tasked to build India’s Star Wars-like weapon systems for the Indian Armed forces in the near future have finally begun testing a vehicle-mounted “gas dynamic laser-based DEW system dubbed ” Aditya” which is a technology demonstrator to prove beam control technology.

LASTEC also plans to develop Air-defence variant of DEWs which can be used against UAVs, Helicopters at a range of 5-10kms which can guard airspace of an area of 10 km with a 360° view and a likely spinoff and a Naval variant for warships will also be developed.

In the US for instance, Northrop Grumman has designed and produced a 150kW laser-based DEW weapons system and have plans in place to develop 100W DEW weapons using advanced solid-state lasers in near future and finally move to Megawatt-class designs with electron-injection lasers which will likely make its debut in 2020 which theoretically damage enemy warships.

Europe’s MBDA also has developed gad-dynamic carbon dioxide laser with 50kW power .Rheinmetall of Germany to has developed a 10kW high-energy laser (HEL) . It’s not clear if Indian Navy plans to get DEWs weapons systems from abroad or will be working with India’s DRDO in developing them indigenously since India’s own R&D in DEWs are still in infancy stage which will require few more years to mature as a weapon system.

Though a 2 years old article but found informative.
Directed Energy Weapons, India’s Strategic Game Changer?

South Asia’s strategic scene is currently oscillating between maintaining deterrence stability while at the same time pursuing technology innovation and modernization through the induction of new strategic weapon systems. The defense research and development community in India has often argued that there shall be a perceptible shift over to non-contact wars in the future, and this situation necessitates maintaining India’s credible minimum deterrent, enhancing deterrent survivability, and augmenting its preclusion value. While the importance of technology, both, in strategy and war, cannot be emphasized anymore than it already has been, it is plausible to argue that the use of technology is far more critical than the technology itself.

The future weapon system that is likely to change the course of war is the Directed Energy Weapon (DEW), which is created on electromagnetic pulse effects, in addition to a variety of other means, without a nuclear blast.* DEWs can be termed as the apex in weapons technology innovatory, apt for dealing with all kinds of asymmetric challenges, including unmanned and light aircraft. DEWs are capable of destroying a target by emitting and transferring extreme levels of energy towards the target. The energy emitted by DEWs can be available in the form of electromagnetic radiation, microwaves, lasers and masers, and particles with mass.* DEWs encompass two distinct fields; high-energy lasers and high power microwaves.

Using laser beams and other concentrated sources, DEWs are the future in so far as military laser (acronym for "light amplification by stimulated emission of radiation") technologies are concerned. Of these, laser weapons by far lead the DEWs pack. The precision of a laser beam weapon is unrivalled primarily owing to its speed, akin to that of light. DEWs are fast racing towards being the most sought after option in comparison to conventional projectile weapons including missile systems, given their accuracy as mentioned earlier, and the range of these weapons, which is far greater than any conventional munitions.

The applicability of laser weapons, more specifically against aerial and naval targets is significant, although the range is subject to meeting certain vital variables including atmospheric conditions and availability of power. Laser weapons can produce a series of strikes, which can be limited only by its power supply. From a military application point of view, a laser weapon is required to generate at the least, a 100-Kilowatt beam. More importantly, for targeting anti-ship missiles, the laser device is required to generate at least one Megawatt of power.

The DEWs aim without using a projectile, and are far more cost effective in comparison to the huge cost estimates surrounding a single missile launch. With military technology innovation on fast track mode, laser weapons are the tool of the future, albeit having to overcome certain looming challenges. These include, determining the final potency of the beam, which gets affected considerably by atmospheric conditions such as clouds, rain, and smog. The laser device requires an expedient source of abundant electricity generation, in addition to efficient cooling equipment that would aid in avoiding any damage caused by overheating.

The advanced weapon development roadmap of the Indian Ministry of Defence till 2020-25 places DEWs as a top priority. The Indian Ministry of Defence’s Headquarters Integrated Defence Staff (HQ IDS) – a joint service headquarters of all three services of the Indian Armed Forces, namely the Army, Navy, and Air Force – acts as the point organization for integration of policy, doctrine, war fighting, and procurement. DEWs have been identified by HQ IDS as the key thrust area until 2025 in itsTechnology Perspective and Capability Roadmap, a document that intends to provide to the Indian defense industry, (both public and private sector), an overview of the direction in which the Armed Forces intend to head in terms of capability over the next 15 years, which in turn would drive contemporary and future technologies’ developmental processes. In terms of laser weapons, the ultimate objective set to be achieved by India should be that these weapons be carried by the three services’ platforms including fighters, naval destroyers, and submarines.

India is currently working upon a series of DEWs to improve its anti-ballistic missile capability. According to officials at the Laser Science and Technology Center (LASTEC), a laboratory developing lasers and related technologies, belonging to the Defense Research and Development Organization (DRDO) – an agency under India’s Ministry of Defence working on various areas of military technology while striving to meet cutting edge weapons technology requirements – a laser weapon (one among the DEWs pack) could fire a beam with a potency of 25 kilowatts to intercept and destruct an incoming ballistic missile in its terminal phase within the range of seven kilometers (4.3 miles). The targeting laser beam raises the shell temperature of the ballistic missile to 400+ degrees Fahrenheit, as a consequence of which the ballistic missile would explode.

Work is also in progress for a 100-kilowatt solid-state laser system to eliminate missiles that are in their boost phase. Besides, LASTEC, functioning under the DRDO, with a mandate to develop DEWs for the Indian Armed Forces, announced in 2010 that it was developing a vehicle-mounted gas dynamic laser-based DEW system under its Aditya project, slated for completion by 2013. Having already overshot its time stipulation, this project is still a work in progress. Once ready, the Aditya project will be a technology demonstrator to prove beam control technology. Last, LASTEC will commence developing solid-state lasers, for which no timeline has yet been set, at least in the public domain.

Last, LASTEC will commence developing solid-state lasers, for which no timeline has yet been set, at least in the public domain.

Although the DRDO, the premier arm of the Ministry of Defence, has made ambitious technology announcements, it needs to be underscored that the plans to develop these high-powered laser weapons are still in their nascent stage. India, not surprisingly, is expected to be confronted with DEWs related research and development bottlenecks, beginning with the expected deficient funding. Post overcoming this challenge, perhaps the most mounting test would be to master the laser’s targeting and tracking system.

While the DRDO has identified DEWs as among key thrust technologies for the next decade, the effort to develop and transform superior technology into affordable and critical military capabilities, decisive factors such as affordability, suitability, dual use, technology base, and modular design will be uphill tasks. Perhaps the greatest technical challenge for the DRDO would come in the form of finding reliable and affordable system integration meeting military platform requirements. Presently, India’s DEWs system are in the research and development stage, and the earliest timeline for them to move out from the laboratory to the battlefield for operational testing and subsequent deployment, going by current trends, should likely be around 2025 or even later.

Laser weapons at LoC may be part of future response to Pakistan challenge

Laser technology has attracted plenty of defence research in the West, with military planners noting virtues such as precision targeting and low cost of usage.

NEW DELHI: As India’s security and diplomatic establishments examine a range of possible current responses to terror-exporting Pakistan, official think tank Niti Aayog is looking at the future options. And no-contact counter offensives that use technology such as laser is high on this list.

Niti Aayog officials told ET off the record that disruptive defence and security technologies will prominently feature in the think tank’s 15-year “vision document,” which will replace five-year plans as the cornerstone of policy thinking. The 12th plan ends in 2016-17.

Niti Aayog member VK Saraswat, who was earlier secretary in Defence Research and Development Organisation, is working on identifying disruptive technologies. The idea is to adopt technologies that radically transform government services, from defence to Swachh Bharat Abhiyan.

Laser technology has attracted plenty of defence research in the West, with military planners noting virtues such as precision targeting and low cost of usage.

Laser weapons systems operate on the basic principle that laser beams are impossible to avoid or detect. They can target both enemy personnel and enemy communications and installations. The US army and navy are most advanced in laser weapons or directed energy weapons research.

There are technological challenges for developing such systems that can be mobile, rugged, cost-effective and functional under a variety of weather conditions.

Niti Aayog’s plans are to get India to adopt laser technology for use in a variety of defence settings, including guarding India’s borders against Pakistan. Such a weapons systems in, say, LoC can be a game-changer, experts say. But development and adoption is a long haul as well.

DRDO developing high energy beam weapons;

project likely to be completed by 2017


In what is being dubbed as Star Wars-like weapons, India's premier defence research lab Defence

Research and Development Organisation (DRDO) is said to be developing Directed Energy

Weapons (DEW). This could include the use of high-energy lasers and high-powered microwaves

as weapons of the future.

Countries like the U.S., Russia, China and others are far ahead of India in the research and

development of DEW, and India too is "trying to make some headway towards such futuristic

weapons," the Times of India reported.

DRDO is currently working on a 10-kilowatt DEW that will enable the armed forces to take down

targets like UAV (unmanned aerial vehicle). It is also working on the "establishment of critical

technologies of precision tracking/pointing and laser beam combination," the report said.

DRDO has already tested the "system" for a range of 800 meters at its Hyderabad-based Centre for

High Energy Systems and Sciences (CHESS). It was reportedly shown to the armed forces at

Ramgarh, Haryana, based Terminal Ballistics Research Laboratory in 2015.

DRDO has also developed smaller systems like laser-based ordnance disposal of IEDs and mines,

hand-held laser dazzlers for use against terrorist and vehicle-mounted laser dazzlers to control

mobs.

The New Delhi-based Laser Science and Technology Centre, a DRDO lab, is said to be working on

a variety of weapon systems ranging from "chemical oxygen iodine lasers" to "high-power fiber

lasers" for strategic applications. One of the projects in development is a 25-kilowatt laser that is

being designed to target a "terminal phase" ballistic missile, at a range of 5 to 7 kms.

The government released Rs 115 crore in February 2014 to CHESS in order to develop

"experimental technology modules for directed energy laser systems," and this added impetus to the

project, which is scheduled to be completed by July 2017.

The DEW is not new to the defence ministry's planners, since the development of DEWs and

electromagnetic pulse (EMP) weapons was classified as "top-priority area" in the 15-year

"technology perspective and capability roadmap" that was prepared by the ministry.

The TOI report also noted the operational significance of such weapon systems -- cost-effective and

flexible, can engage multiple targets, silent and stealthy, no limitation on stock or magazine

capacity and has pinpoint accuracy.

However, one of the challenges for the DRDO scientists is to have a solid-state laser DEWs that can

be used from aircraft and warships, and which can destroy enemy ballistic missiles in their "boost

phase" itself and not wait until the "terminal phase."

Hand held laser weapons are in the realms of science fiction at present where we are concerned. It will take a couple decades to operationalize them. The static DEW, KALI that we are developing requires massive amount of energy and it's huge and cumbersome to transport.

So, we still have a pretty long way to go till we develop small compact and mobile Laser weapon systems along the LoC!
