What It Is

The Dhanush is an indigenous Indian 155mm/45-calibre towed howitzer developed by the Gun Carriage Factory (GCF) Kanpur, part of the Ordnance Factory Board (now Munitions India Limited — MIL). The Dhanush is derived from the Bofors FH-77B design, which India acquired in the 1980s and which became the subject of the Bofors procurement controversy. After decades of legal and political constraints that effectively froze Indian artillery modernisation, the Dhanush represents India's effort to leverage the Bofors design baseline and develop an indigenous production capability. The howitzer features indigenous improvements over the original Bofors, including an improved fire control system, upgraded ammunition handling, and enhanced barrel life. The Indian Army ordered 114 Dhanush guns following cabinet approval in 2020 at an estimated cost of ~₹2,500 crore. The Dhanush has undergone extensive trials in desert, high-altitude, and plains conditions. It is lighter than the Bofors FH-77B (~11.2 tonnes vs ~11.5 tonnes) and offers comparable range with conventional ammunition (~24–30 km) and extended range with ERFB/BB rounds (~36 km).

FAQ

What is the relationship between the Dhanush and the Bofors?

The Dhanush is derived from the Bofors FH-77B 155mm/39-cal howitzer design that India acquired in the 1980s. The Dhanush uses a longer 45-calibre barrel (vs 39-calibre on the Bofors), an improved fire control system, and indigenous production at GCF Kanpur. It retains the Bofors design baseline but incorporates Indian improvements to barrel life, ammunition handling, and fire control.

Sources: [1]

How does the Dhanush compare to the ATAGS?

The Dhanush is a 155mm/45-cal howitzer (~24–30 km range), while the ATAGS is a 155mm/52-cal howitzer (~48 km range). The ATAGS offers significantly longer range, a semi-automatic loader, and computerised fire control, but is heavier (~18.5 tonnes vs ~11.2 tonnes). The Dhanush is lighter and more deployable in mountainous terrain but has shorter range. Both serve different operational niches and are expected to coexist in Indian Army service.

Sources: [1][2]

Why was the Dhanush programme important for India?

The Dhanush represents India's first indigenous artillery production programme since the Bofors controversy of the 1980s effectively froze Indian artillery modernisation for decades. It demonstrated India's capability to leverage acquired design knowledge and develop an indigenous production capability for a critical battlefield system, reducing long-term import dependence.
