Dhanush (bow) is a 155 mm towed howitzer manufactured by Advanced Weapons and Equipment India at Gun Carriage Factory Jabalpur, previously a part of Ordnance Factory Board. The gun was approved for service in 2019 and has been inducted into the Indian Army. The Dhanush project was started by OFB to replace the older 105 mm Indian Field Gun, 105 mm Light Field Gun and the Russian 122 mm guns with a modern 155 mm artillery gun.
