"The 155 mm ERFB ammunition, developed for Bofors gun, is designed to achieve an extended range of 32 km, which is 25 per cent more than its normal range," PXE director Maj Gen Anup Malhotra said.
The shell weighs about 45 kg and it contains high explosive warheads of around 8 kg.
A host of other ammunition like 120 mm Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) and 105 mm Indian Field Guns (IFG) were also test-fired in a demonstration as part of the celebrations of the golden jubilee year of the DRDO.
Explaining the destructive capability of the ammunition, Malhotra said, "a regiment of 18 guns if fired together can neutralise a target of 300 square metre.
"Testing of this shells are carried out with a sample of 33 rounds drawn out randomly from a production lot of 1000 nos for evaluating its different components.
"Three observation posts at approximately 20 km range have been occupied today for observing the fall of shot for assessing consistency," he said.
Similarly, in a successful recovery proof of indigenously developed 130 mm high explosive shells used in 130 mm gun system of Russian origin were conducted for demonstration from the test range.
"This weapon can fire and destroy targets upto a range of 27.5 Km. A 130 mm shell weighs around 32 kg with 6.5 kg of high explosive filling," said Malhotra.
