The meeting of the Defence Acquisition Council (DAC), headed by Defence Minister A K Antony approved a proposal in this regard.
Under the proposal, the Defence Ministry plans to upgrade the 300 M-46 howitzers from 130 mm to 155 mm guns systems.
Indian private sector companies would be competing with state-owned Ordnance Factory Board for the project.
Indian private sector companies such as Tata and L&T have successfully developed mounted 155 mm howitzers and are planning to offer them for trials to the Army for its requirements for artillery modernisation.
