DRDO's Directed Energy Weapon (DEW) Program & LASTEC's Aditya Project



DRDO's CHESS (Center for High Energy Systems and Science), Hyderabad is developing Directed Energy Weapon (DEW) systems for use by the Indian Armed Forces (AFs).

Laser Science and Technology Center (LASTEC) is developing laser source technologies for Directed Energy Weapon (DEW), as also for dazzling and imaging applications.

LASTEC Capability Development

LASTEC has developed core technologies including Gas Dynamic Laser (GDL) and Chemical Oxygen Iodine Lasers (COIL) and demonstrated 100 kW (multi mode) GDL and 20 kW (single mode) COIL sources.

LASTEC's Aditya Gas Dynamic High Power Laser based Directed Energy System

LASTEC's Aditya project was an experimental test bed to seed the critical DEW technologies. The Gas Dynamic High Power laser based Directed Energy System can be broadly divided into two major subsystems:


  1. Laser Power Source
  2. Beam Delivery System






The Laser beam used in a DEW is subject to attenuation (loss of intensity) due to atmospheric air and jitter due to the turbulence within the atmospheric air. The damage caused by the beam progressively reduces with target distance.

In order to cause the stipulated damages at 0.8 km and 2.5 km distance using a 0.7 m aperture telescope, laser power of the order of 100 kW is required . The beam delivery system has to simultaneously perform several roles. It acquires and tracks the distant static and moving target in real time and points and focuses the laser beam on the target. The adaptive optical system has to compensate for the jitter and wave front distortion of the laser beam from the source.



The technology related to laser source, beam delivery and issues related to system integration on mobile platforms were addressed during the execution of the Aditya project which will provide useful input to future laser weapon programs of DRDO

DEW for Use Against UAVs

One of the DEW weapon systems being developed would target UAV's.

Project Progress

In July 2015, CHESS invited tenders for 3 radio control (RC) aero models with minimum wingspan of 1600-mm, min. wing area of 800 sq in., and min fuselage length of 1200-mm. The aero-models should be able to fly at altitudes in excess of 400-m.

It's likely that the procurement is aimed at field testing the IIR sight CHESS has developed for its anti UAV weapon. Typically battlefield mini UAVs fly at around 1000-ft AGL in order to stay clear of small arm fire.


Earlier on March 2, 2015 CHESS invited tenders for Off-axis concave and convex parabolic mirrors.

The concave mirror is required to have a parent focal length of 2000mm and mirror diameter of 150mm, while the convex mirror is required to have a parent focal length of 200mm and a mirror diameter of 25mm.

In early July 2015, DRDO's IRDE (Instruments Research & Development Establishment), Dehradun invited tenders for supply of High Resolution thermal imager for CHESS platform.

The IRDE tender seeks a Thermal Imager based on Pelican-D 640x512 MWIR IDDCA with 14.5X zoom capability. The Imager is required to have recognition range capability of 5-km against a 1.5m x 3m UAV target.

IDDCA (Interleaved Double Dynamical Clustering Analysis) is a sampling algorithm based on clustering.

It appears that the imager being sought by IRDE would be used to aim a DEW developed by CHESS for use against UAVs.

Indian Navy's Interest in DEW

An HT report dated July 20, 2015 quoted a senior navy officer as saying that the Navy plans to develop and deploy high-energy lasers and high-power microwave weapons on Navy ships.

"The navy’s policy and plans wing has identified directed-energy weapons as a key long-term development project. We are sharpening focus on it,” said another officer familiar with the plan.

LASTEC has developed 1 kW fi ber laser through collaboration and development
work of 5 kW and 9 kW fi ber laser sources utilizing complex beam combining technologies has also been initiated.



If someone wonder what a fiber laser system can do
Here is a 30 kw fiber laser from Lockheed Martin






Turning Up The Heat: Latest Evolution Of Lockheed Martin Laser Weapon System Stops Truck In Field Test
laser weapon system successfully disabled the engine of a small truck during a recent field test, demonstrating the rapidly evolving precision capability to protect military forces and critical infrastructure.

Known as ATHENA, for Advanced Test High Energy Asset, the ground-based prototype system burned through the engine manifold in a matter of seconds from more than a mile away. The truck was mounted on a test platform with its engine and drive train running to simulate an operationally-relevant test scenario.

“Fiber-optic lasers are revolutionizing directed energy systems,” said Keoki Jackson, Lockheed Martin chief technology officer. “We are investing in every component of the system – from the optics and beam control to the laser itself – to drive size, weight and power efficiencies. This test represents the next step to providing lightweight and rugged laser weapon systems for military aircraft, helicopters, ships and trucks.”

The demonstration marked the first field testing of an integrated 30-kilowatt, single-mode fiber laser weapon system prototype. Through a technique called spectral beam combining, multiple fiber laser modules form a single, powerful, high-quality beam that provides greater efficiency and lethality than multiple individual 10-kilowatt lasers used in other systems.

ATHENA is based on the Area Defense Anti-Munitions (ADAM) laser weapon system developed by Lockheed Martin in Sunnyvale, California, which has been proven in demonstrations against small airborne and sea-based targets. It incorporates the 30-kilowatt Accelerated Laser Demonstration Initiative (ALADIN) fiber laser developed by the company in Bothell, Washington.

Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 112,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation’s net sales for 2014 were $45.6 billion.

India as a country is poorer than Sub Saharan Africa. How long will you all use the much needed funds for weapons instead of improving sanitation for eg. Pakistan is richer than you all(per capita) but still wisely use funds for better purpose.

Jo log sheeshy kay ghar main rahtey hain woh doosro pain pathar nahi pheka kartey.

You troll about sanitation here, you'll get hit with a "shit storm" of your own making.

Now shoo

Prisoners of Poverty: A Flip Side of Pakistan
Struck with one of the highest inflation rates in the world along with scarce job opportunities, extreme levels of poverty and an endless wave of terrorism that has blanketed the city, residents of Karachi, the industrial hub of Pakistan are certainly going through turbulent times.

According to World Development Indicators (WDI) 60 percent of Pakistan's population lives below the poverty line and 21 percent of the people are earning less than $1.25 a day.



A small population comprises of elites residing in the country. Members of this set of the society have absolutely no idea about the problems that a 'common' man of the metropolis faces.

This individual is not even sure if he will have his mundane needs fulfilled once he returns home from work. With severe power outages, shortage of clean water and food, access to these basic facilities are unavailable most of the time.

However, on the other side, a totally different picture has been painted by the top notch members of the society.

With easy access to internet and other media platforms, these upper class individuals have infused chunks of exuberant practices that could not have been fathomable, let's say five years previously.

To get an idea of their ways, a visit to a wedding of this upscale class is necessary.

Bridal showers that were once entirely unknown to Pakistan's public are now a growing trend. From wedding cakes to the heavy sums of money given to event management companies for opulent stages and flower decorations, this is where the artificial side of Pakistan is seen.

The spendings do not just end here, another trend seen is the 'Mehendi' ceremony where dances are held by the bride and groom's friends and family members. In most cases, choreographers are hired to make this 4-5 hours event a memorable one.

The grandiose wedding features a five to eight course meal followed by sumptuous desserts which makes ones heart ache to see the quantity of food that goes to waste on such occasions.

What is missed out by these spendthrifts is the fact that so many families out there are forced to sleep without having to eat their day's probably one and only meal.

Not only is the wedding extravaganza reaching heights, but birthdays are not in any way losing out on the glamour.

With the class divide increasing at a rate that was never witnessed before, those who are trying hard to survive, develop high levels of frustration within themselves.

The rich need to realize that spending extravagant sums of money over these unnecessary ceremonies will not help the country progress in any way. At this crucial point, investment is necessary in the education and industrial sector.

Once the multitude is well educated with job opportunities for them, the society on an overall basis can progress which will eventually bring about stability
