The video is not showing for me for some reason!!


Did these armour shell ever tested against western MBTs armour like the Leos or challanger?

IN battlefield Tanks will be mobile at most of the time. For a direct hit, MBTs would be needed to stationed on same ground!!!

The site is going through maintenance, The top attack ammunition is fatal for any tank that is western or eastern..

The top attack munition fires a HEAT projectile towards the roof of a tank, If tank roof is not covered with ERA or APS, It is meant to be knocked out..

Actually Swedish Leopard 2A5s (Strv 122), Spanish and Greek Leopard 2A6s have ~20 cm thick armour at the top of their roof, probably enough to deal even with most types of top-attack ATGMs. The armour coverage is greater than the ERA coverage on T-Xx's roofs, but requires a higher weight. Recently IBD Deisenroth, which is one of the biggest armour manufacturing companies in the world, have displayed AMAP-R composite roof armour on some prototypes, which is rather thin (5 cm or below), but should still offer enough protection against such EFP warheads, which lack the punch for penetrating more than ~13 cm in best case.

It would be Very nice if Provide Pics and Detail Information, 20cm is nearly 200mm, That is frontal Armour of some MBTs..

Leopard 2A5 prototype without hull and roof applique armour.
Swedish Strv 122 with extra roof and hull armour.
The version Spain and Greece bought.

I can see partial part of it armored, Though it will provide some protection from HEAT, But i doubt its composite ?

155mm size Heat round is coming from above, And today most ATGM are tandem HEAT, I doubt it can provide protection from latest Top attack Munition, If ERA is placed over the area it will defeat most of the Heat effect..

It is composite for sure. This is an image from a Greek expo which was held when the first licence-produced tanks were ready. Afaik it is just a model, but it shows the "armour boxes" in which the insert should be placed. Afaik it covers the whole cre compartment, the flat area in front of it is the frontal armour and the flat area behind it are the ammunition compartment and turret drives. The armour was designed to protect against artillery submunitions and top-attack missiles (although the technological advantages of the last decade might mean that it can be penetrated by the latest missiles).

155 mm rounds use submunitions with HEAT or EFP warhead. HEAT is typically used in smaller bomblets and EFP in larger submunitons like SMArt or BONUS. In the end the penetration will be less than ~13 cm, the SMArt 155 system is claimed to penetrate ~10-12 cm RHA.

<- EFP projectile

<- 10 cm steel box

As far as ATGMs are concerned, the Austrian Bundesheer has the RBS BILL ATGM with "overfly top-attack mode". The whole missle has a caliber of 15 cm, but the warhead is smaller than that. According to the bundesheer it can penetrate 600 mm RHA, but given the fact the warhead is aiming in a 30° downward it will turn out to penetrate a flat steel roof of 30 cm thickness. If the composite armour is more effective than RHA of the same thickness, it won't be penetrated by the BILL. The TOW versions with top-attack mode use an EFP warhead and EFP penetrates normally less then shaped charges but can be used facing exactly downward.

<- PAL 2000 "BILL"

The other existing type of top-attack ATGMs are from the "dive"-type. At first they are launched in a flightpath facing slightly upwards and latter turn down - but also with an angle similar to the 30° of BILL. SPIKE-LR is claimed to penetrate 700 mm RHA and might even have an impact angle worse than the BILL warhead - so penetration could be prevented by the roof add-on armour. Only heavy ATGMs which can penetrate more than 1000 mm RHA (which is likely enough to penetrate 500 mm RHAe roof armour or 20 cm composite and 70 mm RHA assuming a TE of 2 for the composite armour) should be a problem. There exist new methods to improve the top-attack ATGMs, like using thrust-vectoring to change the impact angle better, but this is rather uncommon at the moment.

Strike Mortar Rounds do have small rockets to change the path and to correct its trajectory, Not a pure TVC but effective as it is.

Though turret roof is still better than most Eastern counterparts even western counterparts, But still these Rounds are effective if hit other place like Engine compartment, Gun barrel, ect..


Interesting Update, But needed to be updated as per newer threads as top attack tandam HEAT..

Do we have any plan to aqure it

Do we have any plan to aqure it

It is not Known we Purchased it or not..

 

[indian_sukhoi]

Hope we do,.....Would be very useful a defending force well digged in against a advancing MBTs!!

This document from FAS mentions on Chapter 6 - 32: Indian Sensor Fuzed Munition for 120 mm mortars and 155 mm artillery.

Things are getting so easy that one will forget how to read a map!

And if the system fails, then there will be one system to address - GOD!

Kuanl,
Not so far in production in India or is it??

CG-84MM MK3..

are this OFB upgraded or original manufactured by the designer???
