VL SRSAM Vertical Launch Unit (VLU) is to support and launch eight (8) Canisterised Missiles (CMs) from a floating platform. The VL SRSAM VLU is mounted on the ship deck. The VLU houses the eight (8) Canisterised Missiles (CMS), Plume Deflector, and Plenum.

An Integrated VLU was fitted into the VLU supporting structure at ITR, Balasore and was tested for hangfire condition in May 2022. The hangfire test was successful and found no plume leakage through any part of VLU during the 7 seconds of the Hangfire event. Post this hangfire event, the VLU was sent back to LnT for assessing the post-study.

The Hangfire test was successfully conducted at ITR on 21/05/2022. During this test, it was observed that some elements of the Launcher were to be studied and reviewed for its reusability. For this, the following sub-components are to be looked into:

  • Actuator Sub Assembly
  • Control Panel Unit Sub-Assembly
  • Drive Unit Sub Assembly
  • Hydraulic Power Unit Sub Assembly
  • Electrical Control System Sub Assembly
  • Missile Canister Assembly
  • Plume Deflector
  • Plenum

The VLU is a critical component of the VL SRSAM weapon system. It provides the necessary support and launch infrastructure for the missiles. The successful completion of the hangfire test is a significant milestone in the development of the VL SRSAM weapon system.

About the VL SRSAM Weapon System

The VL SRSAM is a quick reaction surface-to-air missile system (QR-SAM) being developed by the Defence Research and Development Organisation (DRDO) for the Indian Navy. The system is designed to intercept and destroy supersonic sea-skimming anti-ship missiles, aircraft, and unmanned aerial vehicles (UAVs) at short ranges.

The VL SRSAM is based on the Astra Mk1 air-to-air missile. It is a canisterised missile that can be launched vertically from a ship deck. The missile has a range of over 40 kilometres and a speed of over Mach 2.5.

The VL SRSAM weapon system is expected to be deployed on Indian Navy warships in the coming years. It will provide the Indian Navy with a much-needed capability to defend against a variety of air threats.
