ATGM-LWT (Nag variant) trial must be close. Once all good this would be a great force multiplier. Spike alone can not be procured in enough numbers.
So this is what L&T talking about when they said there will be a new Light weight ATGM under development for Zorawar.
If they are able to make a light variant, why not do that in overall manner? Unless all these Vikram VT variant, LWT variants are actually the same, a lighter multi platform Nag can be very useful. There is that mpatgm firing from Archer sruav project too. Wonder what reason is there, except for airborne vs land based version both need to be lightweight anyway ?
What other tests are done before clearing a system as successful for user trials? This seems the most basic one right now.
How will user trials differ from one by DRDO. And are there any redundant trials b/w both DRDOs and army's trials.. can they or should they be clubbed together

There is the IMTAR v2.0 doc by IAF for the airborne stores. It is huge and you have to check out the specific parts, all are listed thereWhat other tests are done before clearing a system as successful for user trials? This seems the most basic one right now.

for instance you can also check out this UAS certification doc for some idea, I think each system has slightly different method.

Describes the procedure for UAV certification as per Indian Military Airworthniss Authority Procedure

Thank you
Need to merge all the atgm projects under this thread, Nag, helina, mpatgm all.

Third Generation Fire & Forget Man Portable Anti-Tank Guided Missile (MPATGM) with top attack capability was flight-tested successfully against a moving target in KK Ranges, Ahilya Nagar, Maharashtra by DRDO’s Defence Research & Development Laboratory, Hyderabad on January 11, 2026.
How many Gazillion trials still left for this national science project.
Depends on where it is in terms of its maturity. You need an active RFQ for it to undergo user trials (If I am wrong someone can correct me here). So, the IA needs to come forward and say I need such a system and the vendors may apply to supply it. This however does not apply to projects that come under Indigenous Development category. They should follow a step process like the one below:
- PSQR (Preliminary Staff Qualitative Requirements): The Army tells DRDO what they want.
- Developmental Trials: DRDO tests the system (Internal).
- User Trials (FET - Field Evaluation Trials): Once DRDO is confident, they hand it over to the Army for testing.
- Indent/Order: If trials are successful, the Army places an indent with the production agency.
A lot depends on process management when it comes to procurement. If the IA wishes to induct it, they can start a user trial and see if it meets its requirement. The will of the user plays a part as well - I can make things harder for you or I can keep it fair and give you a shot. Apples to Oranges - ATAGS went through a 7 odd year trial period (I do not have the details for trial).
I am not tracking the MPATGM and cannot say if it ready for user trials. Someone monitoring the trails can let you the status (if it is user trial ready). The Spike and the Javelin are being ordered so....

Suppose an indigenous system is ready for user trials and something similar exists in the market from another country. Is there a system which mandates the Army at least conduct user trials of the indigenous weapon before considering foreign systems? Or conduct them in parallel with the foreign weapon system to compare reliability performance etc?
Why are the user trials for our indigenous products so long?
My exposure to the whole procurement cycle is not first hand. There are multiple reasons cited for different systems. OSINT will not give you the exact root cause. Folks have commented that there exists a bias and it seems that in some cases things indeed appear like it. I made a post about small arms AR procurement. The whole thing was just designed to fail. The trial parameters will make you laugh. You can read the article regarding it on the relevant thread.
Yes, if we go by DAP (2020), the Indian product should get the user trials before the foreign lot gets evaluated. Priority is applied even before an open RFQ entailing a global participation is sent out.
IIRC there is a categorization that exists. It goes like this:
Buy (Indian - IDDM): Indigenously Designed, Developed and Manufactured (Highest Priority).
Buy (Indian): Manufactured in India, potentially with foreign design.
Buy and Make (Indian): Initial purchase + Transfer of Technology (ToT).
Buy (Global - Manufacture in India).
Buy (Global): Direct import (Lowest Priority).
So, if an Indian product stand ready via say IDDM it has to be given a certain level of priority during system procurement. The version should be acceptable and the user trial can commence if the nod is given. It be can said that a mechanism exists to promote products based on origin.
Also, If the category for procurement is Indian - IDDM, only Indian vendors are trialed. Foreign systems are excluded from the competition entirely. This is an exclusive trial.
Others should feel free to jump in. I am sure someone monitoring procurement for longer can give an even more detailed reply.
A similar product from another country which is available to buy from global market means it has completed all the IVV stages, respective certification and is it active production or has been cleared for production which is past the LSP/LRIP stages (most of the time).
A product offered for user trial by DRDO means it has neither completed any mandatory certification required , nor any final QAP BoM etc finalised, ivv stages completed, ahsp handed over, forget about production clearance stage past LSP batch. User trial is DRDO demonstration of their technology proven prototypes at an advanced stage. These items are mostly full of huge issues, thereby nothing more than glorified proto units that is passing thru the user eye.
How much confusion can persist between the day night difference of the 2 ?

This should answer why available weapon systems already deployed by leading forces are sought after. Folks unfamiliar with the terms can search for them. Also, read the DAP for clarity about procurement management and procedures.
