    Nope. One major advance of K-4 missile over the Agni series was replacement of maraging steel by composite materials for the casing. Polaris already had an all-composite casing 40-50 years ago. Missile guidance tech has improved leaps and bounds, but propulsion, not that much. It has improved...

    I think K-4 is already 1.8-2 meter dia. Can't really get fatter than that for SLBM, I think. But yeah, there is a lot of misinformation surrounding this stuff.

    I remember that the jump from 3500km range of K4 to the 6000 km range of K6 was supposed to be accomplished by increasing height of missile to 13 meters from 10 meters of K4. This is why K5/6 can only fit in a larger SSBN and hence S-5 class was conceived. But even that 3 meter increase in...

    Impossible. This is K5 or K6 IMHO, not K4. K4 goes in Arihant while K5 and K6 will go in S-5 class SSBN. This image has been shared on DFI before. @porky_kicker or @NeXoft007 can confirm.

    I mean they do work rather well in Abrams:-

    This from the hull or turret?

    Turns out we are wrong. Abrams does have hull blow off panels. One is on the top as shown:- The video also says Abrams has two more panels in the belly. I'd imagine it compromises mine resistance, yet they decided to go forward with it anyway. Sauce:- Now do we know if Arjun has this...

    You can either have blow off panel or you can have armour. You put it below and it compromises mine resistance. I don't think its possible to put blow off panels on hull stowage.

    Ok, lets stop here gentlemen. How about you both forget that argument and tell me your take on this new Armata concept of unprotected turret and a separate armoured crew compartment. Should we go down that route in the FMBT/NGMBT/FRCV/<whatever replaces the T-72>? Those are in the turret...

    See, there is stuff that is good in Arjun. Its not all doom and gloom. But the point here is that it could have been much better. The biggest problem I see is DGMF not taking ownership of either Arjun or a new tank program to succeed Arjun. All I see are useless RFIs like the FRCV. That Pakis...

    The existence of the 120mm DRDO MkII round for Arjun was established in the previous pic you posted itself. I am talking about the figure of 600mm. Its not mentioned in the previous pic you posted nor is it mentioned in this document you posted.

    Trishul Trident is that Sengupta blog na? That is less reliable than IDRW news beat. And trace back your BRF source, its got to be that same photoshopped poster that was the source of misinformation on BRF as well. Its important we cut through the clutter here. If there is no official poster...

    Saw this thing years ago and I remember thinking about how its possible but then I gave them the benefit of the doubt thinking there is no autoloader limitation in Arjun and since the round is integral, maybe its got a longer penetrator that can explain why its 600mm. But its 300mm :doh:

    No. There was a separate poster showing DoP of Arjun round as 600mm. Arjun APFSDS is different because its one-piece, unlike the two-piece T-90 DRDO Mk2. The confusion arises because they are both named DRDO FSAPDS Mk2. But that is the only poster ever to have stated Arjun APFSDS as 600mm...

    That 530mm DoP won't defeat frontal of a T-90S or a Chinese Type-99. To say nothing about the Western behemoths. I do agree about the autoloader limitations being a b!tch, but DRDO FSAPDS round for Arjun is not much better. SAMHO CLGM is also good, but only against tanks without Active...

    Its been clarified enough times that the armour is there behind the gunner sight but its not thick enough. I think it was around 450mm? Not sure. But I'd reccomend you speak to an expert like @Blood+ about the whole Arjun gun sight thingy. He has the most experience in that debate.

    Because that is what the Arjun's armour could and should have been like. Its a massive tank and tanks of that size already exist with much better armour distribution. Its a showcase of how bad the Arjun turret design is. They just wasted a massive potential advantage.

    Looking at the timelines for that 650mm APFSDS project, seems like the original timelines for 2019-20 were pushed back. And its 2022 now, still no progress.
