User trials of indigenous artillery gun today at Pokhran 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.
