DRDO Develops Lightweight Bullet-Proof Jacket For Army – Free PDF Download

What has happened?

• India’s Defence Research and Development Organisation (DRDO) has developed a lightweight bullet-proof jacket,
• That weighs nine kilogrammes and meets the qualitative requirements of the Indian Army, the defence ministry said in a statement on Thursday.

Which laboratory?

• Kanpur-based Defence Materials and Stores Research and Development Establishment (DMSRDE),
• Which is one of the laboratories of the government-run Defence Research and Development Organisation (DRDO), has developed this jacket.

Testing

• The front hard armour panel bullet proof jacket
• was tested at Terminal Ballistics Research Lab in Chandigarh and it met relevant standards of the BIS (Bureau of Indian Standards).
• The front hard armour panel technology used for this new jacket reduces the weight of medium sized bullet proof jacket from 10.4 kg to 9 kg.

Why light weight is necessary?

• Each gram reduction is crucial in enhancing the comfort level of the soldier while ensuring survivability, and this
• is where this development stands out.
• For this purpose, very specific materials and processing technologies have been developed in the laboratories.

Export

• India exports bulletproof jackets to 18 countries.
• Industrial licenses have been issued to 15 companies for manufacturing bulletproof jackets,
• Having production capacity in the country of over 10 lakh per annum to meet the domestic and export requirement.

How Do Bulletproof Vests Work?

• A soccer goal’s net absorbs the ball’s energy.
• It spreads the energy out across all the fibersin the net.
• This slows and then stops the ball’s forward movement.
• The tightly-woven, flexible synthetic fibersin a bulletproof vest do the same thing.
• The fibers in the vest “catch” the bullet.
• They bring it to a stop before it can penetrate the body and cause serious injury or even death.
• The fibersin a bulletproof vest must be packed together much tighter.
• They’re so densely packed that you could think of them as thousands of soccer goal nets overlapped and piled on top of each other.
• That’s where the modern technology of synthetic fibers comes into play.
• As early as 1965, the chemical company DuPont made a synthetic fiber known for its high strength, low weight, and resistance to chemicals, cuts, and fire.
• This fiber was called Kevlar.
• It was soon used to make the first generation of flexible, concealable body armor.

But there is an issue

• Today’s bulletproof vests will protect against most common low-caliber handguns.
• But high-powered weapons, especially rifles, can still penetratebulletproof vests.
• The only protection from these types of weapons is usually “hard” bulletproof armor made of rigid ceramics and metals.
• Unfortunately, these types of body armor are usually too bulky and heavy to wear for everyday use.
