If Ukraine war continue for prolonged period, we will be end up with a strong desi weapon industry.
Order Scope: 184 guns (60% L1 share of 307 systems) under the ₹6,900 Cr MoD contract.

Dhanush artillery gun's barrels are made in Metal & Steel factory, Ishapore.
The raw steel is sourced from Alloy Steel Plant (ASP), Durgapur operated by SAIL. The steel is described as Ultra-High strength (Yield- 1750 to 2000 MPa) low carbon steel with Ni-Cr-Mo additives. Exact composition isn't known. The steel is brought in in billet or slab form melted & refined through LF-VD & ESR processes. Then cast on to an octagonal beam shape.
The cooled cast steel is then re-heated uniformly the pressed in a heavy vertical press to obtain the optimal microstructure. Then it is taken to radial forging to obtain a nearly cylindrical structure:
When the external surface start to cool down, but the inner part is still red hot, the cast steel is taken for internal piercing:
Then heat treatment:
Then the cast barrels are machined in lathe & boring machines:
