The procurement process is part of the Army plan for Mediumisation with indigenous guns and is likely to be completed by the year 2042. In the last decade, four contracts have been concluded for the procurement of a 155 mm howitzer. These Gun Systems have already been inducted and more Regiments are being equipped with these guns. These gun systems include Dhanush, Sharang, Ultra Light Howitzer (ULH) and K-9 Vajra Self Propelled Guns. Dhanush Guns are an electronic upgrade of Bofors Guns, while the Sharang Guns have been up-gunned from 130mm to 155mm calibre.
