Context: The Ordnance Factory Board (OFB) handed over Sharang, the first 130mm M-46 artillery gun upgraded to 155mm to the Indian Army.

What is SHARANG?

Sharang is the 130mm artillery gun ‘up-gunned’ to 155mm, 45 calibre up-gunning based on the Army’s tender.


The gun’s range has now gone from 27 km to over 36 km with the upgrade. It also has more explosive capability and hence and more damage potential. In all, OFB will upgrade 300 130mm guns to 155mm and the contract will be completed in 4 years

This step will reduce the logistic trail of the Army as it does away with the need to carry 130mm shells and support equipment as the mainstay of the Army’s long range artillery is 155mm guns. 


In October 2018Ministry of Defence and the state-owned Ordnance Factory Board signed agreements to upgrade the artillery guns. The Sharang upgrade kit costs less than 7- lakh rupees per gun.


It is an industrial organisation, functioning under the Department of Defence Production of Ministry of Defence, Government of India.  It is engaged in research, development, production, testing, marketing and logistics of a comprehensive product range in the areas of air, land and sea systems.
