May be, the t 90 can handle the same ammo without any difficulty. Or may be the plan is to standardise the gun for the whole tank fleet. In order to have a single set of ammunition. Simplifying logistics of the operation.

Re: Artillery Discussion Thread
Karan M, sorry i am just picking 2 points from your posts but unfortunately only these points are relevant to my response. hence..
Army to induct indigenous howitzers in 2013
these are longer rods (in addition to 3BM-42M) which are not compatible with the auto loaders in T-72/90. IMO they are meant for ARMADA and possibly the T-90AM/MS which has a bustle mount on the turret for the same 'but' since there is question mark over both wrt production, it is possible the rounds too are in limbo.The BM46 is clearly not in series production.
i am afraid that is not the case. army asked for 2 versions which are approved. one is 39cal upgraded and the other 45cal reengineered.IA was not interested in 39 cal and asked only for higher cal
Army to induct indigenous howitzers in 2013
Re: Artillery Discussion Thread
The upgraded long rods IMO, at this point, are more of a wishlist than anything else. They are good for internet debates where Russians claim equality with the west, but even the upgraded T-90s are not shown with production series BM-4XX upgraded rounds..
Re: howitzers, this is what I meant.. IA plans to induct only the 45 cal ones or at this point of time only they have orders...

I doubt they'd go for the 39 cal weapons.. they might have asked for a prototype though, but its pretty old in the tooth for todays requirements though a step up from the 155mm.

i guess IA with no howitzers in decades is playing it safe. while 39cal (being a replica) would be easier (!) and would serve as backup as it only involves upgrades in terms of ballistic computers, communication and the like where as the 45cal is wholly reengineered version which might face some issues.Re: howitzers, this is what I meant..

Re: Artillery Discussion Thread
Yeah, but they still havent placed any orders for the 39 cal. Agree with you that they should have just ordered a few hundred 39 cal to at least build up numbers while the mythical 45 cal super howitzers came from "somewhere"..
Re: Artillery Discussion Thread
The 45 cal re-engineerred is not the problem. It tested all right in Dec 2012 and yet in Au 2013 it suffers ignominy.
Its the shell that causes the issues.

Re: Artillery Discussion Thread
Hope you are right. Is there any report that mentions the timeframe for OFB to have completed their enquiry conclusions about the incident?
Re: Artillery Discussion Thread
The first article posted by pragnya above states:
The only difference between the 39 and 45 caliber is extra range--30km vs 40km, unless I'm missing something. The shells are the same. So it's quite perplexing that the army would not first order the lower-risk 39 immediately when it is desperately short of guns and instead order the OFB's experimental 45 with the risk of not getting anything anytime soon. Of course it's preferable to have a longer range weapon but couldn't they first be safe and then task OFB to develop the 45 in the meantime? Something just doesn't add up.
The second states:While one gun has been upgraded with the electronic suite incorporating ballistic computers, servo valves and communication systems to provide automation, the second gun has been upgraded by fitting a new 45 calibre barrel, enabling it to achieve a range of 40 km.
These seem to say that four 39 caliber guns were ordered, two of which were upgrades and two were same as original with no changes, and two 45 caliber.A senior military source said the OFB has now been asked to manufacture two guns of the 155/39 mm caliber, the original make of the Bofors gun bought in the 80s. Two others would be of the same caliber but upgraded with new capabilities. The OFB has also been asked to make two guns of 155/45 mm caliber.

1. Range is also a function of the type of munition, not just barrel length. If munition development (in a desi effort), or market availability, (foreign purchase), is not in sync, expect more issues like were faced originally with Arjun MK I.
2. Regardless of the barrel length and munition type, as you get into 30-35+ km fire missions, accuracy/dispersion starts to become a major issue. What is "proved" on a range under highly controlled conditions seldom translates into real world performance.
3. Is the OFB "project" track independent of the army's "reported" plans to replace even 105mm with 155mm systems, for which RFIs have been issued yet again? If yes, then the OFB is being sent on a fool's errand with the 45 cal devpt., the 39 cal. should suffice.
What one fears will happen, similar to the HAL HTT40 episode is that OFB, partly led down the garden path by the army, partly by its own institutional ineptitude, will try and project itself on the larger requirement, competing with the global-pvt. desi JVs in the fray. Much recrimination will result, including on BR...
Re: Artillery Discussion Thread
seems like M777 may not be procured. IA/MOD IMO must have consulted and analysed the air portability usp of M777 and must have come to the same conclusions as did RV here who also quoted an artillery officer who substantiated it.
it seems to me they are heavily investing on the OFB variants of Bofors both 39 and 45 cal. it may take a year or a couple to fix the issues before prod begins. OTOH the cost factor wrt M777 seems to be a roadblock for its import!! besides it only equips a few IA regiments of the MSC. DRDO is on record ARDE version of 52 cal gun will be ready for trials in 3 years. so by 2017 it is hoped all towed variety incl 39cal/45cal/52cal guns should be in place. also of note is any gun procurement from abroad at this stage will fructify only around similar timeline if TOT/assembly is part of the deal - which is more than likely.
as for the truck mounted variety - i guess field is open. TATA/L&T will have a head start while Kalyani and ARDE may compete too if they mount their guns on a suitable vehicle.
BHIM with Denel gun 'possibly' may make a comeback with Denel blacklist over now.
fwiw.

Re: Artillery Discussion Thread
If I remember correctly BHEL was awarded Single vendor non tender deal to produce High Power Naval Guns for Rs. 3500 crores in Screw Driver JV with an Italian Company. What was the technology absorbed by BHEL in the said deal and how can it help desi Bofors? The ToT contract should have given theoretical access to metallurgy to BHEL. Some instances of labeling by DPSUs while falsely claiming indigenisation:-
ATGMs
Fuzes
Thermal Sights
Night Sights
AESA radars
Naval Guns
FSAPDS Ammo
TATRA trucks
ARVs
Naval Engines etc

Re: Artillery Discussion Thread
While I am happy that finally indigenous procurement of artillery might be falling into place, we should have procured atleast 10-15 no.s of M-777 just for reverse engineering.
Re: Artillery Discussion Thread
IA artillery acquisition has been the biggest farce. The OFB 45 cal prototype was first displayed around 2005 timeframe.
At the same time as the OFB M46 upgrade was first displayed.
The OFB M46 upgrade also reportedly did well in the initial tests, but a barrel then appears have busted or had some other problems. The upgraded gun was apparently also displayed at some even in the middle east, complete with test firings as well. The results at the time were positive, if I recall.
However, the contract was placed with Soltam for 180 guns. The Soltam upgrade also, got into some trouble initially, with regards to the performance of the upgraded guns. However, the problems were later rectified and 180 upgraded guns are since in use.
Soltam meanwhile got blacklisted and hence no follow up contract was signed.
What is the worrying aspect is that all the while the OFB upgrade package, as well as the OFB version of the bofors with 39 cal and 45 cal versions were always available. These did not material out of thin air, one fine day. The picture of the 45 cal upgraded bofors has existed right here on BR, since 2005-06.
This also did not come about in 1 days effort. OFB has been making the 39 cal barrel of the bofors since many years and many of the old bofors guns are currently serving in IA, with barrels and many other parts made by GCF.
So, IA knew for a long time, that local derived version of the bofors, is a possibility.
The army was just too busy carrying out endless trials of uber cool latest guns from around the world, during this time to take note.
Even now, if they are so desperately short of guns, they could have gone ahead and placed the order for 114 nos. as per the existing 39 cal configuration. The plan was also supposed to be as such. Hence OFB made 2 prototypes of 39 cal guns and 2 of 45 cal.
But instead of getting the game started, IA preferred to go for 45 cal guns only and not waste the effort in first getting a few 39 cal guns and letting OFB production also come upto speed.

What optimism do you find in the Govt's Arty procurement program since Bofors in 1986?
Knowing reality helps aviod depression when the truth is revealed.

TATA SED/DRDOs new Ballistic Computer for the T-90. Form and fit for a drop in replacement of T-90 BC, but based on the Arjun Ballistic Computer with its software/internal hardware.
Significance lies in the ammunition types mentioned for compatibility.
http://3.bp.blogspot.com/-kV7lH7QT4O0/T ... 0S+MBT.jpg
AMK-339 is nothing else but 3BM42.
AMK-340A is IMI CL3254M
(AMK-340 was the dropped local round - supplanted by AMK-340A).
Also shows (under APDS) the Russian rounds prior to BM42 are also supported (till BM26). BM32 was DU and not available for export.

Re: Artillery Discussion Thread
Posted for your viewing pleasure. Tests of the Excalibur GPS guided 155mm artillery with an "Average Miss Distance" of ~2m. For something thats shot out of a cannon, having to withstand 1000's of Gs, the accuracy is mind boggling.
Re: Artillery Discussion Thread
Some very powerful lobby, influenced by big corporations is behind this mess .
Not taking a decision in a definite time frame that effects national interest,is not only a case of incompetence but also is a crime.
Feels like Lokpal is essential, at least for artillery procurement.

Re: Artillery Discussion Thread
How no one has asked anything about IA putting 600+ crore to buy BM-21 GRAD system?
The report was hazy and spoke only about IA buying the extended range BM-21 rockets. We also know that Hinduja has won contract to provide 100 trucks for mounting BM-21 system - which we've presumed involves replacing the original trucks which came from Russia. And given the fact that we have 5 x BM-21 Regiments, the 100 number for trucks fits pretty well.
By any chance - is it possible that IA is looking to introduce these 122mm 40 rocket monsters into wider service? We know that DRDO had worked on the rockets and extended the range; may be we also have some smart munition and guidance stuff going.
It would be awesome to have 1 x BM-21 battery of 6 x launchers per infantry division.

Because no one has seen the news. Having said so, if the desire is to have additional Grads, then does it mean that some thing is wrong with the Pinaka?
As the Grad is an old system, that has a longer reload time and a smaller warhead, when compared to the Pinaka.
An addition to the range can be in 2 cases,
1) Reduce the warhead size and add more propellent to the basic rocket.
2) Change the chemical composition of the rocket fuel , where by its thrust is increased.
Having said so, I would be a lot more impressed, if we were increasing the Pinaka launcher buy, and at the same time designing different types of rocket packs for the launcher. Eg 122 MM or 300 MM, as it is a modular system and the rocket packs can be changed, while retaining the same basic launcher.

From looks of it, the system relies on M46 elevation control (which i think is manual). Hopefully, at least the turret rotates 360 degrees.
Will be a good system if they up-gun the M46 to 155mm.
On a positive note, extra engines for this contraption should help drive the MBT engines costs down (If they get enough overall orders for license production).

From wiki:
From wiki:
The turret-less vehicle has an open area in the centre for the gun and crew but retains the driver's position and includes a horizontal metal shield for overhead protection.
To withstand higher firing stresses and to cater for longer recoil the Vijayanta tank's hull has been elongated with seven bogie wheel stations on either side. The stability to the vehicle during firing is provided by unique hydraulic suspension locking system. The self-propelled medium artillery gun can fire both HE and AP ammunition and has a maximum range of 27km. The gun has a limited static traverse 12½% on either side and an elevation of +45% to -2%. The system can stow 30 rounds of separate loading ammunition. A total of 100 M-46 Catapult systems were built and are now being phased out from active service may be replaced by an unspecified number and type of 155mm self-propelled howitzers.

It says that the internal trials of the Desi bofors 'Dhanush' are complete. More than 100 rounds were fired in balasore range.hit targets 38 km away.
The fifth prototype manufactured by the GCF was tested for two weeks, ending first week of Dec. issues relating to auto loading in previous prototypes were resolved in this gun, also in view of the bursting of barrel of the fourth prototype, proper care was taken. the gun is on to winter trials with IA.
