Recently, Vertical Launch Short Range Surface to Air Missile (VL-SRSAM) was successfully flight-tested by Defence Research & Development Organisation (DRDO) and the Indian Navy from an Indian Naval Ship at Integrated Test Range (ITR), Chandipur off the coast of Odisha.
- VL-SRSAM has been designed and developed jointly by three facilities of the Defence Research and Development Organisation for deployment of Indian Naval warships.
- The missile has the capability of neutralizing various aerial threats at close ranges including sea-skimming targets.
- Sea skimming is a technique many anti-ship missiles and some fighter or strike aircraft use to avoid radar and infrared detection.
- The missile 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 Astra missile which is a Beyond Visual Range Air to Air missile.
- Astra ("weapon") is India's first air-to-air all weather beyond-visual-range active radar homing air-to-air missile, developed by the Defence Research and Development Organization.
- A Beyond-Visual-Range missile (BVR) is an air-to-air missile that is capable of engaging at ranges of 20 nautical miles or beyond.
- Cruciform wings: They are four small wings arranged like a cross on four sides and give the projective a stable aerodynamic posture.
- Thrust Vectoring: It is the ability to change the direction of the thrust from its engine, control the angular velocity and the attitude of the missile.
- Thrust is the force which moves an aircraft through the air.
- Canisterised system: The inside environment is controlled, thus making its transport and storage easier and improving the shelf life of weapons.
- It is a combat in and on the sea, the ocean, or any other battlespace involving a major body of water such as a large lake or wide river.
- Defence Mechanism:
- It is a countermeasure technology used worldwide to protect naval ships from enemy’s radar and Radio Frequency (RF) missile seekers.
- Missiles to counter Anti-Ship missiles:
- These systems have to have a swift detection mechanism and quick response to warships.
