I still have a hard time believing 16x vlsrsam vls would be that huge
This should not faze you now, VLS packaging in IN ships had always been very bad. If they are truly 16 missiles than yeah that's pretty bad and well atleast one of the reason is they are using single VLS for each missile and not quadpacking, the extra space needed for each VLS adds a lot in single VLS system.
I am expecting vlsrsam to match the performance of camm missile. If needed not only vlsrsam but Barak lrsam can be quadpacked as it's dimensions match more or less that of ESSM missile. There is a universal VLS being developed by drdo which will house all indian developed missiles, I don't know if it will also include current brahmos or there will be another bigger strike VLS from them.
Anyway, I wouldn't be surprised if we see some 32 vlsrsam or even 16 on ships. See the difference between vl mica VLS and mk41 VLS, you'll understand the size difference.

Defence ministry to allow private companies to develop military helicopters
The Defence Ministry has decided to amend the DAP rules to allow private defence companies to collaborate with Indian Defence PSUs with a majority stake and produce required weapon systems.

New Delhi: In a major push to “Atmanirbhar Bharat” in military hardware sector, the Defence Ministry has decided to amend the Defence Acquisition Procedure (DAP) manual to allow private sector to collaborate with an Indian Defence PSUs with a majority stake and manufacture the required weapon system.

According to South Block officials, this collaboration will be tested in the development and manufacture of Indian Multi-Role Helicopter (IMRH), which will ultimately replace all Russian built Mi-17 and Mi-8 helicopters in the Indian military’s present inventory. The IMRH will have a 13 tons take-off weight and will perform with the Indian armed forces in air assault, air attack, anti-submarine, anti-ship, military transport and VVIP roles.

It is understood that Indian private sector companies have already shown their eagerness to participate in the project with the Defence Ministry telling them to start manufacturing in the next seven years. The French Safran has already signed an MoU with Indian HAL on July 8, 2022, to form a new joint venture company to develop, produce and support the IMRH engine including the naval variant.

From what i know that is not true and booster and main engines are not same.
But doubts about that vls remain ..i remember there were drawings from tenders would be great to get vls dimensions from it
VL-SRSAM is fielding Single staged solid fueled rocket motor.
Once this motor ignites, the missile is launched out of VLS cell, missile achieve the requested altitude and finally stirs the missile towards the target. During flight (interception path) towards target the fuel will run out at some time and the missiles finally glides towards the target on the stored energy it has.
Hence the term booster can be use synonymously with main engine.

You are thinking in lines of ramjet engines (Brahmos, Akash SAM) or turbofan engine (Nirbhay/ITCM) where their is one dedicated (separate) single stage solid fuel rocket motor to give the missile desired speed and altitude whereby the main engine can kick in.

Single staged solid fueled rocket motor based VL-SRSRAM doesn't need this. Its main engine does both roles hence used synonymously .

The thing is...other than GE winning it, i find no other evidence to prove that a contract has been signed,the delivery has been made and hal produces it locally.
Same, no evidence, to support the claim[read somewhere the deal is signed], but GE start supplying MWF[2019, I think] engines, and said[2022], next step, local production with hal.

Ok, a very basic question.
Astra Mk1, a single pulse solid propellant rocket has max range of 110 km with Max interception speed of Mach 4.5
Meteor, has a max range of 200 km and Max interception speed of Mach 4.0+
SFDR, meteor category missile has max range of 340 km and according to DRDO poster has max interception speed of Mach 3.6.
So my question is, are we compromising with speed to achieve greater range, or there is some other engineering limitations coming to play?

It is not just a question dimension.
We use hot launch VLS.
Heavier the missile bigger the booster, bigger the booster more powerful the exhaust, more powerful the exhaust more reinforced your VLS needs to be.
Compare it with Barak-8 VLS, then we can get some clarity

Its preliminary specification.
Lets things settle down before making things concrete.
Ramjet engines needs to be properly designed and manufactured to a very high tolerance else they will have issues sustaining combustion at higher Mach speed.
This is even more true with solid fueled systems.

Do we have any systems like HIMARS or PHL-16 under development?

Yes. Pinaka MRLS is the system.
Based on information on HIMARS and PHL-16.
PHL-16 uses BRE rockets
Range is from 40 km to 360km.
Himars 40 km to 380 km.
'Meanwhile current Pinaka - 40 km to 90 Km with 120 km under testing. Unfortunately we don't have further development on this project. But we have another solution in the form.

Basically from 120 to 200 km. We have Prahaar, Pragati, Pranash. (150,170,200).

Status : Not inducted.

Improved version - Pralay (Range : 150 - 500 Km)


Status : Under going testing. Not inducted.


We have the rocket force required. But out of 3 we have only commissioned Pinaka. Other 2 should be inducted soon, this will basically level the field.
