How did you make up you mind that Indian Arjun which is a heavy tank should be bring down to 50 tons. A heavy tank e.g Leapord, Abraham, Merkava are all 60 tons wt category tank. If your requirement of heavy armour, and firepower and 4 man crew, the wt (according to Indian Army ASR)would be 60+ tons period. However, use of better metallugy, 1500HP engine will boost the Arjun Capability.
Indian tanks will have to run in desert, mud around country side in any escalation with Pak. An Indian road and old bridge can barely take load of 50 tons.
Germany have quality infrastructure. We need tank in range of 40-50 tons
Where you get the figure of 80-100 G, pls provide me the source.
It's all comparative. A-Darter is built by Denel dynamics by improving R-Darter which was itself
built with some israeli assistance from Python-4 program.
A-Darter claims to have agility up to 100 G.
Astra official spec says 30 G.
The A-Darter has four major sections: guidance section, warhead, control, and rocket motor.[20] It uses a streamlined design with low aerodynamic drag in a wingless airframe, ensuring ranges beyond those of traditional short-range missiles.[22] It is fitted with a thrust vectoring control (TVC) system[23] to provide agility up to 100 times the force of gravity (100G).[15]

Difference of Astra and Spyder is not the G-level, but the Seeker which is Active as compare to Radar Guided Passive, and the SBR (Software based Radar), and the algorithm, in which israel have a good lead. Trishul SAM is 2 generation old design and technology, and now need to be dumped.
Sypder have fins near the nose which make it more manoeuvrable.
Astra have trapazoidal wing/fins near read mid.
The fins/wings are movable. They are supposed to control the missile.
Leave aside the seeker. Astra without seeker using Command guidance are still no match for Spyder since we lack the software, algorithm expertise as compared to Israel. Even if we put the fins near nose, we dont have the expertise in SW to loop them and juggle with it.
Eventually we need to make those 2/3rd gen basic QRSAM work as They form the base
1. Thrust vector & single rocket engine propulsion
2. Guidance & control system with fins, wings, jet vanes
Israel made these work before they came up with dual pulse rocket engine, advanced control system using seeker tech
