India’s first indigenous Air Dropped Container ‘SAHAYAK-NG’ tested successfully by DRDO


  • The SAHAYAK-NG, an air droppable container was tested successfully by the Defence Ministry. 
  • It is the first indigenously developed air droppable container.
  • The SAHAYAK-NG can carry payload up to fifty kilograms.
  • GPS enabled  droppable container can be dropped from heavy aircraft.
  • It is an advanced version of SHAYAK Mk I.
  • The SAHAYAK-NG containers are completely water tight.
  • They are designed to withstand water entry shocks.
  • The rate of descent of SAHAYAK-NG container is controlled by a parachute system.
  • The SHAYAK-NG was designed by Defence Research Development Organization (DRDO) and Avantel, a private company. 
  • The other entities involved in the development of SAHAYAK-NG are NTSL, Visakhapatnam and ARDE, Agra.
  • The test trials of SAHAYAK-NG were conducted by the Indian Navy and DRDO.
  • The SAHAYAK-NG will help to provide critical engineering stores to ships that are deployed more than two thousand kilo metres from the coast.
  • It reduces the requirement of ships to come close to the coast to collect spares and stores.
  • The three major types of air drop are low-velocity airdrop, high-velocity air drop and free fall air drop.
  • In a low-velocity airdrop, the parachutes are designed to slow down the air droppable container as much as possible before it hits the ground.
  • What is high-velocity air drop?
  • This type is meant to stabilize the fall. 
  • The parachute will slow the air droppable container but not the extent of low-velocity airdrop. 
  • The method is used in delivering military ready to eat meals. LAPES is a high velocity airdrop system. LAPES is Low Altitude Parachute Extraction System. 
  • It is currently the most advanced air drop system. It uses touch and go type pattern where the load is ejected in extremely low altitude.
  • Free Fall Airdrop is a type where no parachute is used and the load is allowed to fall under gravity is called free fall airdrop.
