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.
Q) Which among the following statements are correct?
- INS Khukri was the first missile boat of India.
- INS Vinash was the first frigate naval ship in India.
- 1 only
- 2 only
- Both 1 & 2
- None of the above
