We don't import material for entire system like tank, ship, artillery but for critical section or at least the technology to make such material.
I believe Arjun gun barrel is imported.
Not to forget GTRE GTX-35VS Kaveri failure with respect to HAL Tejas.
We were screwed when Russian denied us ToT for gun barrel for T-90.
The technology to synthesize metal/material used to manufacture combustion or fuel injunction system for Internal Combustion Engine is imported from German companies.
Just compare weight and barrel life METAMORPHOSIS 155 mm GUN vs M777. Our 155mm gun is even more heavy than M198 howitzer.
Our 105mm guns almost weigh same (slightly less) as M777 but range of only 17.4 km compared to range of M777 of 24 km to 40km depending on the round.
Even Bhim T-6 SPH used Denel 155 mm L52 G5 gun.
As for DRDO artillery the PSQRs demand new technology such as barrel coating. So the plan is to first build the barrel using current technologies and then try coating. Once that barrel development technology has matured, we can add new technologies and improve its performance. A number of foreign firms are willing to offer the coating technology. We are in dialogue but nothing has been firmed up yet. In order to cut down on time, we may get the technology from abroad, especially about the barrel coating.
This is what is generally done. We buy technology from foreign firm and then manufacture. This does not make our metallurgy capability good.
Finally we should stop leaving in past. Now days the is a trend has started to develop metallurgy capabilities indigenous.
Get your facts right before making your tall claims boss.
Believe whatever you want to but ARDE L52 of Arjun is developed and produced in India,not imported.
Again we were not screwed because OFB already produces the 2A46M main gun of T 90S.
Do you know even the difference between M777 and OFB L45....Huh??The first one is meant to be an ultra light towed howitzer with very high Ti content and and it's of L39 calibre.It doesn't come equipped with an APU,ammunitions craines and automatic rammers.
On the other hand,Danhush has a longer barrel (thus a much greater range) and it comes equipped with an all terrain chasis powered by an APU,effectively transforming it into a semi self propelled gun.Besides,it has autoloaders and ammunition craines.
And when was the 105mm IFG was designed again??An 155mm gun with a longer barrel will always have a longer reach than a 105mm gun,what's the big fuss about this?? How a "Respected Member" like yourself could even compare both systematic??Even then at least,get your facts correct - the maximum range of IFG is 19 km with old ammo.And M777 doesn't have 40 km range with base bleed rounds,it's more like ~28 km in the plains.
Yes,Bhim SPH did use a Denel gun and turret and why??Have you ever asked that question to yourself??Because DRDO was never asked by Indian Army to develop a 155mm gun....it's as simple as that.
It's not like ARDE can not develop an artillery gun.Infact,they did develop a 185mm heavy arty gun as far back as mid 80's but IA was not interested.But I know you didn't know that.
I will not reply to rest of your post since it's your opinion based on anywhere from half truths to outright fictions of your mind.
