Very good info for Indian Army, and armoured corps.
It's seems that Arjun will have major changes.
I have a few notes:
And US-based Cummins offering a customised QSK-38 liquid-cooled, direct-injection engine coupled to the ESM-500. In late 2009, a combination of the QSK-38/ESM-500 powerpack was selected as the winner, following which Cummins India began customising this powerpack design
So CVRDE choose engine not integate in power-pack yet, and not used on any tank yet.
Wartisla V8X-1500 was propably rejected due to fuel comsumption like in gas turbine, and Germans never alowed for full transfer technology of MB-883 (whit law to re-export...) Intresting that Perkins CV12 Condor loose - price was to big? More or less QSK-38:
Cummins G-Drive Generator Engines
is not used in tanks yet.
For ensuring MBT survivability, the Defence Metallurgical Research Laboratory (DMRL) — located in Kanchanbagh, Hyderabad — has developed a Mk2 variant of its Kanchan modular armour, which was made by sandwiching composite panels (ceramic, alumina, fibre- glass and nickel-alloy) between rolled homogenous armour (RHA) plates to defeat APFDS or HEAT rounds.
Interesting I will say...very interesting.
developed multi-layered multi-functional fibre-reinforced polymer (FRP) composite hull/turret sub-structures at much lower weights in comparison with metallic counterparts
This solution (as single layerd) was used in Sviet Union in BDD Armour
But intresting infos too.
is co-cured composites integral armour (CIA), which comprises ceramic tiles and rubber sandwiched between two FRP composites layers. While the outer FRP composite layer acts as a cover and provides confinement, the ceramic layer provides primary protection against ballistic impact, and the inner FRP composite layer acts as the structural part as well as secondary energy absorbing mechanism. The rubber layer isolates stiff and brittle ceramic tiles from structural member.
And this really interesting...descriptions is very simmilar to the polisz CAWA-2 amour and one of it's 3 model...
CAWA-2:
Those values for CAWA-2 are given for some LOS. Anone can image how protection may look in mucht thicker Arjun turret.
For protecting the Arjun Mk2 against tandem-charge PRGs and guided anti-tank missiles, the CVRDE and IMI have co-developed a lightweight non-energetic reactive armour (NERA) package, comprising tiles in which two metal plates sandwich an inert liner, such as rubber. When struck by a shaped-charge's metal jet, some of the impact energy is dissipated into the inert liner layer, and the resulting high-pressure causes a localised bending or bulging of the plates in the area of the impact. As the plates bulge, the point of jet impact shifts with the plate-bulging, increasing the effective thickness of the armour.
Finally! NERA from Germany went to Israel and now it will go to the Arjun tank. It's greate info. Protection achived by NERA is able to reduce more then 96% of single SC warhed penetration abilities, or completly stopped precursor in double SC warhed, and reduce main warhed up to 30%. In purest eample NERA is used on Leopard-2A5-A7 turret (those "wedges on turret") on Strv.122, Leo-2A6HEL/E/Ex hull, Leo-2A7 hull, and on Merkava Mk.IV modular armour.
German NERA provide by IBD:
very simple NERA tests:

For ensuring fool-proof protection against new-generation anti-armour guided-missiles, the Arjun Mk2 will incorporate both multi-threat warning sensors and an active protection system (APS). The former, supplied by Elbit Systems, comprises four E-LWS sensors that can detect, categorise and pinpoint laser sources, including rangefinders, designators, beam-riders, and infra-red illuminators. E-LWS also enables direction indication for all threats, as well as audio and visual warnings. It is immune to reflection, gunfire, lightning, fire and self-electro-optical operations. The Iron Fist APS, being supplied by IMI, uses two fixed radar sensors to detect potential threats and measures distance and trajectory for providing the APS' fire-control (...) Unlike other systems, the Iron Fist uses only the blast effect to defeat the threat, crushing the soft components of a shaped-charge or deflecting and destabilising the guided-missile or kinetic rod in their flight. The interceptor is made of combustible material, and is fully consumed in the explosion. Without the risk of shrapnel(...)
Iron Fist can handle multiple targets simultaneously with different intercept methods, including multiple countermeasures fired at two simultaneous threats at the same sector.
Another good news.
Iron Fist was rejected by Isreaeli army (Trophy aka "Windbreaker" was slighty better), but is relativly cheap, and quite good against limited attack. The last part decribe max. ability Iron Fist to protect. This system is not able to deal against Kornet-MR (or other new soltion when more then 2-3 ATGM's can be guided in one salvo) but can be very effective againt RPG, older ATGM's, modern single-fired -ATGMs etc.
Photos form IronFist test in Israel:
. Finally, a mobile camouflage system has been developed and integrated into the Arjun Mk2 in collaboration with Sweden's Barracuda Camouflage Ltd to reduce the vehicle's signature against all known sensors and smart munitions.
Saab Barracuda...well -it's not so bad multispectral cover, it can be placed on first generation cover:
(On left - intermat painting, next NAKIDKA, and on right bottom corner - Saab Barracua).
It's importan to notice that they are newest and mucht better solution then Barracuda (rejected by Australian army after test in Australia) like russian Kontrast/Tarnina, polish Berberys, Israeli (don't remember name) etc.
