'Dhanush', India;s indigenous towed artillery gun


New Delhi[/URL]: If all goes well over the next few days, the Indian Army's prayers for a towed artillery gun looks set to be answered soon.

The summer trials of 'Dhanush', a 155-mm, 45 calibre gun built by the Ordnance Factory Board (OFB), a defence public sector unit, are slated to begin at the Pokhran firing ranges from Friday, highly placed sources have told NDTV. The winter trials, a prerequisite along with summer tests, was carried out in the high altitude areas of Sikkim in the winter of 2013.

If the gun, based on the design and manufacturing technology provided by Swedish gun maker Bofors AG in the late 1980s, passes the test in the week-long trials in the heat of Rajasthan's desert, the OFB is likely to get the final clearance for manufacturing the desi but improved version of the original Bofors gun (the earlier version was of 39 caliber and, hence, had a shorter barrel) and fill a critical gap in India's artillery arsenal.

For more than 15 years, the Army's artillery modernisation plan has suffered one way or the other, the tendering process getting embroiled in allegations of manipulation and corruption at various stages. At least two foreign manufacturers have been blacklisted in the process. The Army, which needs over 1,500 towed artillery guns at an estimated cost of over Rs. 10,000 crore, is desperate to get new guns since no new guns have been inducted after the Bofors joined the Indian Army in the late 1980s.

The Army has given an initial indent of 116 guns to the OFB, with an option to increase the order to 416 pieces of artillery. The OFB gun, with its electronic sighting and laying system (Ballistic Control System or BCS) for aiming the gun at the target, will be a major improvement over the Bofors' manual system. More importantly, the Dhanush is likely to be priced at Rs. 14 crore a piece, less than half of a similar gun manufactured abroad.

While the original Bofors gun has a maximum effective range of 27 kilometres, 'Dhanush' can fire a salvo up to 38 kilometres in the plains, those involved with the gun's manufacturing said.

If the trials go off smoothly and the Army then gives the final clearance, the OFB has plans to double its manufacturing capacity from the current 18 guns a year.

I pray that the Army inducts hundreds of these. It will virtually eliminate the need to import artillery guns of one category at least. If all goes well, we could as well further research on this technology to modernize our future artillery gun tech.

If I am not wrong,so far we had to import Arty guns of one calliber only,the 155mms.All other catagories were filled by Indian guns.

Kalyani Group on the other hand, few months back had informed, that they are working on a Indigenius Ultra light Long Range Howitzer, Baba Kalyani owner of the Kalyani Groups had even infact questioned Purchase of Expensive M777 ultra-light howitzers artillery guns and had informed to the media outlet, that they are working on 155 millimetre (mm)/39 calibre ultra-light howitzers with effective range of 22 km , Gun will be built with Technical collaboration with US based Mandus Group and will be ready Next Year .
