Indian Missiles and Munitions Discussion

Compiling what we know about the VL-ASTRA/VL-SRSAM so far with info from the tenders and some of our speculations :

There have been two tenders of the VL-SRSAM put out so far. Both of the tenders are now closed. One was for the supply of Vertical Launch System & Cannisters which included :

  • 3 units of Vertical Launch Systems
  • 10 unit of cannisters
  • 2 units of dummy missiles
  • 10 units of Pyro bolts
  • 3 units of RF splitters
  • 16 units of MIL-STD-1553 data bus couplers

It seems the launch module will have 16 missiles in individual cannisters.

The missiles will be hot launched. The hot gases from the missile's exhaust will be let off by a central uptake vent :

More than a year back I found a CFD study of plume management system. The document said it was for a naval AD launch system. The design is very similar to that shown in the tenders. This is probably it :

As with all new missiles nowadays, this one will also be hermetically sealed. The sealing extends the shelf life of the missile and makes is relatively safer to store.

The missile will be very snug fit inside the cannister. If you look though the clutter in the image below, you will see that the missile has 4 long chord wings(2 are visible). The wings runs along almost the entire length of the rocket motor :

@hellbent found that a private company is preparing to produce the airframe shown below. It looks similar to the early version of the ASTRA. But we know the ASTRA missile was re-designed and the long chord wings were replaced by cropped delta wings :

@hellbent speculated then this was the airframe of the VL-ASTRA/VL-SRSAM. It seems he was right. He also made a picture comparing the 3 missiles : Initial ASTRA, current ASTRA & the VL-ASTRA :

The comparison is on point. Just one little thing is missing. Look at the tender pic above the VL-SRSAM missile has jet vane control(JVC). A JVC is needed for making rapid changes in direction. Air defence missiles need that, even the AAD missile has JVCs.

Another tender called in for making missile integration jigs. For a complex missile all the different components can't be made in the same facility. Rather components from different facilities come into one place for final assembly and testing. This is where the jigs come in, they hold components in alignment as they get assembled.

Given VL-SRSAM's lineage from the ASTRA, jigs for one missile should work for the other too. IAF & IN ordered 248 ASTRA missiles recently, once that production line hits max production capacity VL-SRSAM can be made there too. That would save us a lot of money. Most our corvettes, frigates & destroyers are lightly armed. We need the VL-SRSAM ASAP.

I wonder if the SRSAM's VLS is compatible with the Barak-8. Else the will be adding another new VLS in service. When will we standardize naval VLS ? 😒

It should be able to do this.

The pic you posted regarding Astra old , Astra new , VL Astra was done when pic of VL SRSAM ( VL Astra ) was not available and hence was speculative and limited by the scant information available then .

Later when pic's of VL SRSAM became available I posted this new one , which is upto date and answers all your queries.

Previously I had speculated it was RUDRAM 2 air to surface missile , but later I realised it is not , it is a new surface to surface missile. Possibly the new version of shourya which was reported to be tested on 3 October was this missile.

As of now all I can say this missile shares much of its features with SMART , hence both could be part of a new ( or follow on shaurya ) family of surface to surface missiles. Since the pic is a wind tunnel model hence it looks small but in real its dimensions could be more or less same as shourya ( and a tad smaller than SMART )
