What DRDO needs is restructuring. I beleive that all defence Research and Development (R&D) organisations in India should be privatised, atleast to a certain extent. Scientists in DRDO are not paid a decent package compared to their private sector counterparts. This results in most of the new college graduates going abroad or into the private sectors. If we are to progress in indegenous development, we should allocate more funds to salaries of R&D personnel. When it comes to the defence of the nation, we want the best people working on it.

Su here is the common problem that is existing in thought process we by default assume that public sector does no good thing. You need to understand the foundation stone put by these organizations. Think some 50 years before in what condition our country was. At that time if government has not taken the decision to make such organizations who was having the capacity for such endeavors? Private sector is not some "sanjeevani" for everything. Private organizations are driven out of profit. Lot of technologies developed by DRDO has been transferred to private sector for commercial use. Take an example in 1980's which company was eligible for taking a project like LCA? Do you think any company could have been agreed to take such a project with the amount of funding government was ready to give? The wast amount of infrastructure needed for testing like wind tunnels, engine test facilities, material labs and all. Who could have been ready to invest so much amount with the primary user not even ready to commit the numbers for it. Private sector is continuously encouraged because they are more efficient when it comes to serial production. There entry is happening just look in to Mahindra's Rakshak. Tata is building launchers for Akash system, L&T is involved in production of lot of vessels but still the core technology development is done by DRDO. After 6th pay commission there salary issue is sorted out to a certain extent. Government is taking the initiative the armed forces should cough up some funds from there budget for R&D prjects this will bring in some responsibility from there side also. For UAV's DRDO has taken private companies on board so they can understand from the starting the nitty gritty of manufacturing such complex systems. Lot of initiatives are already taken. Private sector needs lot of help from government to become competitive in international arena.

Because some junior artist at the DRDO decided that making the MCA look like an exact replica of the Raptor would be cool.
IIT develops technology to produce stealth aircraft
Materials scientists at the Indian Institute of Technology in Roorkee (IIT-R) have developed microwave absorbing nanocomposite coatings that could make aircraft almost invisible to radar.
The technology for building invisible, or stealth aircraft, is a closely guarded secret of developed countries and a handful of laboratories in India are doing research in this area.
Radars that emit pulses of microwave radiation identify flying aircraft by detecting the radiation reflected by the aircraft’s metallic body. The nanocomposite coatings developed by Rahul Sharma, R.C. Agarwala and Vijaya Agarwala at IIT-R absorb most of the incident radiation and reflect very little.
Sharma, who revealed his team’s work at an international nanomaterials conference held recently at the Indian Institute of Science in Bangalore, believes their nano-product is a significant step in developing a technology to enable aircraft escape radar surveillance and protect its equipment from electronic “jamming”.
Nanoparticles - so called because of their very small size - are known to exhibit unique physical and chemical properties. The IIT team found that crystals of “barium hexaferrite” with particle size of 10-15 nanometres have the ability to absorb microwaves. (Human hair, for comparison, is 100,000 nanometres thick). They developed special processes for synthesizing the nanopowder and formulating it as a coating.
Sharma said that the nanocomposite coating on the aluminium sheet absorbed 89 percent of incident microwaves at 15 giga hertz - the frequency normally used by radars — reflecting only 11 percent. A stealth aircraft should ideally absorb all the incident radiation and reflect nothing.

Indian Stealth Technology
KOLKATA: India could soon be the third country in the world, after the US and France, to have a stealth bomber fighter aircraft in its armoury.
The Kolkata-based Indian Association for Cultivation of Science (IACS) has developed a technology to convert ordinary light combat aircraft into stealth jets that would go undetected on radar. The first stage of the experiment, which commenced in 1999, has been successfully concluded. The defence ministry has approved the technology and has given the go-ahead for "full-scale production" to begin. It is expected to start in about six months? time.
According to IACS scientists associated with the project, the technology uses a special material to construct a shield on the plexi-glass canopies. It is the glass cover of the pit that usually betrays the presence of an aircraft as it reflects the laser beam that is emitted to catch them on the radar. The shield will cover the pit and deflect the laser beam on the shield in all directions.
"This will make sure the aircraft remains undetected on the radar. We are not sure if the same technology is used in France and the US. It has been developed in our own way and using our own techniques. If it works out well, this would be a big step for defence technology in India," said a scientist.
Defence officials said the advanced combat aircraft made in the US and France have a similar shield on the plexi-glass canopies. "This shield gives the canopies a golden tinge. This special layer scatters the laser beams emitted from a radar site either on the ground or in the air (AWACS). We?ve been trying to develop this technology for some time. The shield developed by IACS will boost our indigenisation efforts," an official said.
During the exercises at Kalaikunda where US F-16s took part, IAF officials got a closer look at the gold-tinted canopies. They also got a chance to test the technique by using ground-based radar. Interestingly, the F-16s from Singapore did not have the shield as the technology has not been transferred.
The defence authorities were so impressed with the new technology that they decided to fast-track the process and start full-scale production of the canopy following a test at Jodhpur recently.
"They had the option of going for a pilot project initially but they chose to skip it," said an IACS official. Fighter jets like Jaguars, MiGs, Mirages and Sukhois will now be fitted with this special canopy to enhance their stealth capabilities

What in the name of great indian defence journalism is a laser that is emitted to catch them on the radar?

The golden tinge thingy is a fact, but the laser.... well, what's this guy doing writing in the papers? He is the next HG Wells. (Maybe he's inspired by the Star Wars

The real problem is the cost cutting, you have a defence story, have a journo who knows a thing or two about it, so many good men from our military forces retire every year, hire one of them.The golden tinge thingy is a fact, but the laser.... well, what's this guy doing writing in the papers? He is the next HG Wells. (Maybe he's inspired by the Star Wars
Instead they have these guys reporting on everything from kids toys to ISROs moon mission, pathetic.
This is the information age.

I guess the jurno is talking about the Pencil Beams emitted by AESA.

Those will still be a cone of EM radiation instead of Light Amplification by Stimulated Emission of Radiation.
The gold tint canopy has been around since the mid 80s.
I do not think he knows anything about the things he is talking about, judging by the way the jorno portrays this new coated canopy to be able to make the aircraft a stealth aircraft instead of just cutting down its radar cross section by a notch.
That is why i said its the information age, how difficult it is to search for topics on google and have a little understanding of what one is writing about before releasing it for a national news paper (or its website).
That’s the same pathetic story about every single field which is reported upon by the media, most of the times the journos are completely alien to the field, just tasked with finishing the article.
If they wanted they could have installed it with ease, here is a exported F-16 with the golden tint.

Sigapore did not want the feature in its F-16s.
