T-14, Leclerc,K2 :shock::crazy:
T-14 is a jumbo...how does it fit into our requirements?
This should be scrapped
Instead give Arjun and Indianised T-90 to TATA, they will make a better from R&D
If really I have to buy anything I shall buy Leo2A7 ret are bye bye

A recent tweet by Saurav Jha says NGMBT can be just 41T ....
How is it even possible ? Unless a very light armour is used
And armour may be light but it not must be lightly armoured
So such armour which despite of being light will be able to give adequate protection
So a breakthrough in armour technology perticularly metallergy ....
So is DRDO already achieved it otherwise how they can be so sure?

Actually if you read this paper published in the January edition of DSJ, it is basically a statsistical simulation study on vehicle configuration based on some existing data on automobile structures and its regression and ANOVA based modelling.

It gives Evolutionary design : 54 tons ;
Revolutionary design : 41 tons.

In reality when DRDO will build the prototype there will be much more. For comparison the evolutionary design seems to be a future iteration of Arjun Mk2 which weighs 68 tons.
So you can add 10-14 tons to the Revolutionary designs safely. This will include add on ERA, NERA and latest Kanchan armour, 120/130 mm smoothbore gun , latest electronics etc. Still it will fall in the 50-55 ton category similar to Armata and will be the perfect candidate for FRCV tender.

Quote from the conclusion of the paper :
A DOE based on regression with ANOVA for evaluating two different configurations namely evolutionary and revolutionary design for GNMBT is presented. This methodology saves considerable time during the configuration stage to arrive at weight estimates for the design. However, it is to be noted that the system weight and volume estimates used for the DOE evaluation are based on 95 per cent confidence level and hence there are always possibilities for the weight to be on the higher side which will still qualify it for a sub 50 t tank. Finally, this paper does agree that many approaches for the problem exists and this paper presents only an alternate approach to choose an acceptable configuration for both the designer and user".
Hence my comments on the paper :
1. This is a Design of experiment based statistical study with a confidence level of 95 %.
2. There are other alternative statistical studies and this is just one of them.
3. Paper takes the gun system to be of 120/125/130 mm as part of this study but still arrives as the same weight of 41 tons and 54 tons for all the above configuration. In contrast. we know not only gun system but weight of ammunition of each caliber will also be different. This point needs clarity.
3. No physical prototypes is actually built. The subsystem themselves are in various stages of developement.
4. The only safe conclusion is the revolutionary design is 10-13 tons less weight than the evolutionary one.
