In another big boost to the Indian Army's artillery modernisation programme, the first home-built artillery gun will undergo its first user trials today at Pokhran, Rajasthan.

This gun is being manufactured by the Ordnance Factory Board (OFB) on the basis of the design transferred by the Bofors in 1986. The designs have since then been gathering dust owing to the taint on these Swedish gun.

However, as the repeated efforts of the Indian Army hit a naught, the force along with the OFB decided to manufacture the gun at home.

The indigenous gun will be upgraded version of the Bofors. So far the OFB is refusing to call it a Bofors gun. In any case the Indian Army has already placed an order of 114 guns.
 
This seems to be very fast furn of events. Little while ago there was no discussion of indigenous gun, now we have one which is ready for user trial(even though its maid our of 1980's - 90's tech). I am sure OFB must have maid new changes in it.

I just hope IA and Babus take it as initial step towards indigenous and if there is any limitations in the gun let that be taken care in next upgrade and not the import way. Atleast now we have a indigenous gun which can be upgraded and regularly to make it a world class product in coming years. IA should also understand that they can get these gun's in any number where as they will have to go through complex process while importing a little better product.

I wish all the best and hope GOD gives some sense to decision makers.....

:sniper:
 
What if they could have started producing em a decade ago ?? we have designs since long!! wtf!!

But still better late then never! Now OFB should do mass production of these guns!!

These guns still use 80's technology. It is better if they wait and 'update' with the latest techs with the help of BAE or someone.
 
which caliber rounds it'll fire??same like bofors??
 
so few people will shut up their mouths that we cant make a gun . First ICBM then gun ... WOW .
 
why they are not invite kalyani Group

Kalyani Group artillery to be featured

Army chief General V K Singh’s leaked letter to defence minister A K Antony, which flagged the country’s lack of defence preparedness, casts a shadow over Defexpo India 2012, which kicks off in New Delhi tomorrow. However, the silver linings in the four-day event would be the impressive presence of several Indian private companies and newcomers in developing complex weaponry, with capabilities the defence ministry (MoD) can no longer ignore.

Among the most visible would be the Pune-headquartered Kalyani Group, which would emphatically project its ambition to develop artillery systems for the Indian Army. With foreign artillery procurement stalled for two decades, Baba Kalyani — who has shaped his flagship company, Bharat Forge, into the world’s largest forgings manufacturer — has committed the finance, the manpower and the strategic mind space he believes would make the Kalyani Group a full-spectrum developer of artillery systems.

Kalyani intends to start by building a 155 mm, 52-calibre towed howitzer, which the army desperately wants. Several years of user trials of foreign guns have only resulted in vendors being rejected, blacklisted, or withdrawn from the contest. Kalyani is now boldly offering an Indian alternative.

“I will offer to the Indian Army a fully developed artillery gun system, integrating all the command and control elements, before 2015,” he asserts.

To this end, the Kalyani Group has imported from Austrian gun manufacturer Maschinenfabrik Liezen (MFL) a service version of its famous 155 mm, 45-calibre, autonomous gun system, which had impressed Indian gunners when they evaluated it in the mid-1980s (though they bought the Bofors gun instead).

The Kalyani Group has also bought, knocked down and transported to India an entire operational artillery gun factory from Swiss company RUAG. Instead of learning the ropes of manufacturing artillery from scratch, Kalyani’s designers in Pune intend to absorb foreign technology, thereby leapfrogging an extended development process. Unlike many Indian private companies, Baba Kalyani is investing his own money into building capabilities. Given Bharat Forge’s hardcore engineering pedigree, he is confident he has the solution.

Says Kalyani: “There are the DRDO ((Defence Research & Development Organisation), the OFB (Ordnance Factory Board) and other excellent organisations that have design talent and capability. What India lacks is the ability to convert designs into manufactured products. This is where the Kalyani Group comes in. Building an artillery gun system is largely about materials, forgings and manufacturing. We have in our group the capability to be a top-class manufacturer of precision products.”

Kalyani Steel would provide the steel and metallurgy. The drives, engine, transmission, etc would be built by Automotive Axles Ltd, the Rs 2,000-crore Kalyani Group company and the largest manufacturer of axles in the region.

Alongside the engineering bravado, there is realism, too, about the Kalyani Group’s inexperience in creating the sophisticated software that underpins the gun control, fire correction and command and control systems, about 50 per cent of the overall gun system.

“Our strategy is to collaborate with entities that already have capabilities in electronics and guidance. (For this) we are in constant dialogue with the DRDO and the MoD. But we are confident about the precision engineering needed for the mechanical parts of the gun,” says Kalyani.

The only “missing link”, as Kalyani puts it, is the reliance on the MoD for testing facilities. Guns under development must be periodically tested through live firing. In India, this can only be conducted in cooperation with the Army. The MoD, rattled by the repeated failures of artillery gun procurement programmes, has already initiated two projects in the public sector to develop an artillery gun. The OFB has been asked to construct two 155 mm, 39-calibre guns from the engineering drawings that came with the Bofors gun in the mid-1980s. The OFB would then try to upgrade these into longer-range 155 mm, 45-calibre guns.

Simultaneously, the MoD has sanctioned Rs 150 crore for the DRDO to develop a 155 mm, 52-calibre gun. The DRDO’s Armament R&D Establishment (ARDE), Pune, would soon float a tender for an Indian industrial partner, in which the Kalyani Group intends to bid.

Such is the aggressiveness within the Group that it intends to develop its own gun on a parallel track, even if it becomes an industrial partner to the DRDO for the ARDE’s gun. Rajinder Bhatia, who would head this project, says, “We are willing to compete against ourselves. On one track, we will work with the DRDO, funded by the government. On our own track, we will fund ourselves. Baba Kalyani is willing to commit Rs 100 crore for this.”
 
I think same as bofors ? 155mm ?



And i think technology of 2000 and after is still considered as modern technology! No ?
Depends upon what the technology is. You can't call JF-17 a modern technology even though it is closer to 2010.
But if by modern technology, you mean something like this.
Designation: FH-77 B05 L52
Manufactured by: Bofors Defence AB

Type: Weapons & Weapon Systems

Name: Towed gun


The FH 77B05 L52 is a further development of the successful FH 77B02 L39 howitzer system. The system meets or supersedes all requirements for a modern, towed artillery system, which is made possible through a number of improvements.
The longer barrel and larger chamber volume result in extended firing range of more than 40 km and enable firing of the next generation smart ammunition.
Onboard ballistic computer enabling calculating firing data, automatic laying and firing control, automatic input of ammunition data and meteorological data.
The FH 77B05 L52 has its own land navigation system, eliminating the need for surveying and alignment giving the complete system a very low LCC.
BENEFITS
• Integrated navigation, positioning and aligning system and onboard ballistic calculation
• Automatic servo controlled laying
• Intra-howitzer radio communication
• Intra-battery communication > 5 km
• Handles modular charges and bag charges
• Spares and logistics similar to FH77B
• Direct firing capability out to 2 km
• MRSI capability, up to 5 hits in a target momentarely
Mobility
Over long distances, a cross country truck tows the gun.
The towing truck and gun can travel at the speed of 80 km/h. For short periods of time and when road conditions allow, the speed can increase.
For cross-country driving, the gun can be tandem-driven from the towing truck. Maximum speed is about 8 km/h and cross-country mobility is excellent.
Over short distances, the gun can be driven independently at speeds of up to 8 km/h.
For deploy/redeployment the gun uses its own power unit.
Gun in/out of action time (trained crew) is less than 90 seconds.
Firing
One of the most important attributes of the Field Howitzer 77B05 is the high rate of fire, i.e. its ability to fire a great number of rounds in a specified time, and MRSI (Multiple Round Simultaneous Impact).
The gun has an automatic laying system with on-board ballistic calculation.
Howitzer Computer Unit (HCU)
The HCU contains the GUI (Gun Users Interface) software and the software for ballistic calculations. It also handles communication with:
• CCM (Control Computer Module) controlling the system for loading, laying and firing, and also receives data from the INS
• Laser Range Finder
• Muzzle Velocity System
• Barrel Temperature Sensor
• MRR for sending and receiving data messages
HCU
Processor Intel Pentium III 500 MHz
• Ram 256 MB SDRAM
• HDD 10 GB removable
• Power specification 10 - 30 VDC with 5 min UPS
CCM
• Power card Convert 24 V to 5 V
• CPU card
• CPU TMS320C32, 50 MHz, 512 kB EEPROM
• Logic card Signals IN/OUT
Gun laying is carried out hydraulically using variable servo valves. Laying can be carried out using the following modes:
• Normal:
Automatic laying by the HCU. The HCU calculates obtained firing data, prevents laying outside the gun’s laying and firing limitations and automatically lays onto target.
• Direct Fire:
When laying using the joystick, the HCU calculates the ?ring data automatically and aiming takes place with no further action. The HCU prevents laying outside the gun’s laying and ?ring limitations.
• Technician’s mode:
Manual laying using the joystick - will override laying and firing limitations.

Then, yes. It will be considered as modern.
 
In the original Howitzers supply contract, Bofors supplied 410 fully assembled units to India in 1986 and the contract was technology transfer to OFB to manufacture further 1000 guns. Then the scandal broke-out and the whole thing went into a deep freeze. I suppose only now OFB has made use of the technology acquired from Bofors to manufacture the guns.
 
I assume the Bofors taint is from the scandal, from what I know, Bofors has always made good guns.
 
This gun will meet the towed requirement (over 1200 are needed).

The OFB has taken the original 155/39 bofors design and done the following:

replaced the barrel to 45 times the diameter (155/45) which increases the range from 22 to 40 km

Ballistic computers installed

Servo valves

communications gear
