Indigenous Vertical Launch Short Range surface-to-air missile

Defence Research and Development Organisation and Indian Navy successfully flight tested Vertical Launch Short Range Surface to Air Missile (VL-SRSAM) recently.

Vertical Launch Short Range Surface to Air Missile (VL-SRSAM):

• VL-SRSAM is a canisterised system, which means it is stored and operated from specially designed compartments.
• In the canister, the inside environment is controlled thus making its transport and storage easier and improving the shelf life of weapons.
• It is jointly designed by three facilities of the DRDO for Indian Naval warships, is meant for neutralising various aerial threats at close ranges including sea-skimming targets.
• The VL-SRSAM system has been designed to strike high-speed airborne targets at the range of 40 to 50 km and at an altitude of around 15 km. 
• Its design is based on the Astra missile, which is a Beyond Visual Range Air to Air missile.
• Two key features of the VL-SRSAM are cruciform wings and thrust vectoring.
• The cruciform wings are four small wings arranged like a cross on four sides and give the projective a stable aerodynamic posture.
• The thrust vectoring is an ability to change the direction of the thrust from its engine controls the angular velocity and the attitude of the missile.
