    Indian Tank Ammunition Scenario

    Re: Tender for T-90S Tank Ammunition Destroying penetrators is stupidity, especially if they are not faulty. They could had been reused.

    Indian Tank Ammunition Scenario

    Problem with older two piece ammunition for 125mm smoothbore guns is that these older APFSDS rounds use so called ring sabot, such ring sabot as we can see is very short. So even if such ammunition is very fast (~1,700 m/s muzzle velocity), because of large stabilization fins, they also tend to...

    Indian Tank Ammunition Scenario

    Yeah, Russians use only 3BK-29 and 3BK-29M, 3BK-31 was a new round, but there are no sources saying it went in to production.

    Indian Tank Ammunition Scenario

    Lenght of penetrator don't fit to what we can see on photo. And on the last photo there is no lenght of penetrator. So did You just invented these figures earlier?!

    Indian Tank Ammunition Scenario

    This is completely wrong for T-54/55 series. You first provides information that these tanks were rearmed with British L7 105mm rifled gun, and later You says that these tanks are using Soviet/Russian ammunition for 100mm D-10 rifled gun series. :facepalm: Lenght of projectiles is complete...

    Indian Tank Ammunition Scenario

    IMHO CL-20 might be perfect HEAT (High Explosive Anti Tank) shaped charge warhead filler, but propellant charge definetly will be different... not to mention that besides APFSDS all other types of ammunition do not need powerfull propelant charges. The gun service life is messured in EFC...

    Indian Tank Ammunition Scenario

    Indeed, it is widely known fact that shaped charge warheads armor penetration depends on warhead calliber and how powerfull is explosive filler needed to create shaped charge jet.

    Indian Tank Ammunition Scenario

    Hmmm, indeed, it is more than possible. Pressure generated by typical explosive filler is probably much higher than a propellant charge filler. Especially one claimed to be such powerfull. And there is also one more concern, if such explosive can be used as explosive filler for HESH, HESH use...

    Indian Tank Ammunition Scenario

    Hmmm, wonder if this can be used as propelant charge. And how it could interfere with gun barrel service life.

    Indian Tank Ammunition Scenario

    ? As far as I know CL-20 is propellant charge not explosive filler right? And nope, it wound be usefull with HESH, such types of ammunition do not have a need to have more powerfull propelant charges to fly faster. Yes and no. Armor penetration levels depends not only on how fast penetrator is...

    Indian Tank Ammunition Scenario

    ? Both autoloader of older type in T-72's and later type in T-90's also in T-90MS is designed to use two piece ammunition only. In T-90A and T-90MS only modification that was done is to give a bit more space for longer APFSDS penetrators, nothing more, these autoloaders still can't use single...

    Indian Tank Ammunition Scenario

    This autoloader was designed to fire two piece ammunition exactly because lenght and because desire to make it as compact as possible. Even standard one piece HEAT ammunition can't be used in this autoloader. Upgrades to autoloader in T-90A and T-90MS were done for two piece ammunition also...

    Indian Tank Ammunition Scenario

    No, LAHAT can't be used in T-90S because it is one piece ammunition, while T-90S autoloader can use only two piece ammunition, so even 9M119 Invar GLATGM is a two piece ammunition. Besides this 9M119 being a 125mm calliber have higher penetration levels of it's warhead than LAHAT that is 105mm...

    Indian Tank Ammunition Scenario

    T-90S ballistic computer needs a source code for ammunition data update?! In NATO tanks everything is stored on some sort of data cards, if You have different ammo You just swap a data card and choose ammunition in ballistic computer... well at least this is how it looks in M1 series, should...

    Indian Tank Ammunition Scenario

    So maybe India should talk with Germans or Americans, I think that it is possible for them to adapt their KE penetrators and propelant charges for T-72, T-90 and Arjun tanks, Germans can offer DM43, DM53 and DM63 based projectiles while Americans can offer KEW-A1 and KEW-A2 based projectiles...

    It is too much sensitive to weather conditions (too high temperatures)? Or something else?

    Indian Tank Ammunition Scenario

    Why Indian Army use for excercises combat ammunition and not practice ammunition? :confused: BTW, about these accidents, so there were explosions and cook-off of ammunition inside T-72 and possibly T-90 tanks? I heard and seen similiar accidents in Russia, IRCC some crews were dead, not good...
