Dhanush 155-mm/45-cal Gun Built by Ordnance Factory Board at DefExpo 2014

Ordnance Factory Board (OFB) developed Dhanush 155-mm/45-cal Gun

Dhanush was developed as an Ordnance Factory Board (OFB) - Army initiative using blueprints obtained from Bofors, Sweden in the late 1980s under the TOT clause of the contract to purchase Bofors 155-mm/39-cal guns.

Dhanush is often referred to as upgraded Bofors gun, but OFB says that development of Dhaush was more than an upgrade.

Besides the change in the caliber of the gun, from 39 to 45, a lot else has changed.

The gun features a modified baffle muzzle brake for improved efficiency, a modified loading trough to enable BMCS Z-6 firing, an inertial navigation system for orientation and fixation, an auto laying system, muzzle velocity reader, unified sighting system, ammunition display unit and a communication system.

The gun has a muzzle velocity of 885 m/s and a range of 38-km (ERFB-BB).

OFB told IDP that the problem that caused the barrel of the gun to burst during trials has been resolved and trials of the gun are proceeding.
