Even that would be unfortunately not enough. For the stereotypical "comparative trial," it only consists of a fire control test and an engine run. However, it would require an actual combat to prove the worthiness of this tank so it won't be soon the Arjun becomes a world class tank.
The trial is more complicated then just that. Its not about what tank is better.
But which tank best fulfills the army's retirements.
For example the IA has overheating problems with both the Arjun and T-90 in the rajastan desert.
While DRDO made specialized cooling systems for effected systems.
the Russians installed an Air conditioners in the T-90 and said that would do the trick.
Now the Russians are known for their simple solutions, so there system may very well be effective.
But that's what these trials are to find out.
Which on of these tanks can best fit the requirements of the army.
The Indian military total failure to support indengious Arjun & LCA is a joke.
Both the Arjun & the LCA are modern on paper then the russian counterparts ie T90 & MIG21/MIG29.
Yet the Army & the Air force want Russian or other imported hardware.
TAKE A LEAF OUT OF PAKISTANS book.
JF17 THUNDER is clearly inferior to F16/52 and certainly no match for SU30MKI yet the PAF are stil happy to induct it appears and steadily improve.
LOOK AT THE INDIAN NAVY building frigates destroyers and now nuke subs and a new 40k tonne carrier.
THE ARMY & AIR FORCE are letting india,s indengious efforts down.
Don't drag the IAF down to the corrupt hole of the IA.
They have neglected in the past. But they fully support domestic industry today. taking an active participation in development programs.
Even supporting RnD in ISRO.
Once they get rid of the old mig fleets, they can focus more in Domestic.
Arjun vs. T-90, that's the guts of it isn't it? Obviously, paper specs only, nothing rock solid.
It's not about what is better.
Its about which tank suits the Indian Army's requirements best.
It may be T-90 vs Arjun but the battle is not for, I am better title.
But which tank works better for IA.
And have you put your simulators to good use? Put them up against much foes and proved decisive victories as of late?
That's what this trial is to decide the IA needs a tank that meets its requirements best. Which is that T-90 or Arjun
