HESH is a legacy system, hang over of 70s British tank.
The tank itself is a British "legacy" system since 1915 or so!
That in nutshell is the set of facts.
Added later >> HESH is also not going to cut it in the evolving warfare world. It's bunker busting capacities are of much limited type and are restricted only to spalling
The new shell system has three features -- available is a single shell. Lets see how HESH stacks up.
Air burst --> Impossible and meaningless in HESH context.
Cracking a gap in the reinforced structure for infantry to use the gap --> HESH can not do it.
Piercing a concrete or light armor --> HESH does not pierce at all.
What HESH does is, stick to the surface of armor or concrete and explode, and the shock waves inside the structure kill.
This is a very limited type of application, for example useless against walls, bunds or ditches, it will work only for enclosed structures like Tank or Pill boxes.
Ah.. Sanku Maharaj Ji , has spoken facts NOT
, but rather imagined make believe.
In fact, HESH
was INVENTED specifically "originally as an anti-fortification "wallbuster" munition for use against concrete." .. In fact, specialized combat demolition vehicles like this M728 Combat Engineering Vehicle
, use guess what .. a HESH round!
Oh well, ever since it was invented, it has been used for demolition,bunker busting and stuff against structures, specifically reinforced concrete, especially in specialized demolition roles, but Sanku Maharaj Ji in all his imagined wisdom dismisses that as "useless" against walls, bunds and ditches (it is perfect in busting such stuff, like the M728 was deployed in Iraq to do, to breach the Iraqi sand berms) and is of course highly effective against exposed infantry (HESH rounds contain a large amount of explosive)
I really dont get the love Vina has for HESH; it has practically been obsoleted for nearly 20 years, if not more.
. HESH round works only when it is fired from a rifled gun! It was never "obsolete", it is just that when the American and German and Russian tanks switched to smooth bore , the ability to fire this round was lost /given up, and those tanks became a primarily tank vs tank at 2km weapon !
Now with the Isreali's recent combat experience in Lebanon, when they faced asymmetrical warfare from Hizbollah and it's fortifications, and hand held anti armor weapons, the limitations of the smooth bore and it's optimization for anti tank becomes crystal clear to them and the need for a HESH like capability is felt by them and they develop a similar capability given the limitations they have via electronics and other gee whiz stuff!
The Arjun rifled cannon already is designed with that in mind and the Indian army's GSQR was prescient in noting that they might have to fight in urban /built up areas and we already have that capability!
Note, the tanks that DON'T have that capability are the smooth bore 125mm equipped Russian tanks in IA service! And so, pronto, run to the Isrealis and buy the round and the associated tank electronics if you want the capability!
It really is the capability of an all round flexible gun was one optimized for tank vs tank at 2 Km. Now that the tank vs tank has taken a firm back seat and you need more capabilities, the weakness of that smooth bore design choice becomes obvious. And oh, HEAT is a dead duck. No one will use that against armored vehicles and is useless in anything else. So out of the two weapons that a smooth bore has, one is totally useless (HEAT) against modern armor, the other (APFSDS) is useless against anything other than armor!
