We should acquire a few first. Then see if we can build them locally. Which would be a lengthy process even if we can.
MLRS wouldn't be a big deal as we already produce some with low ranges, now it's time to go for some long range rockets. Building indigenous ballistic missiles is the real deal for which we should start the process as soon as possible.
Who will manufacture these locally? Government company or private company?
Government company I suppose, the PM has already declared to build new plants to manufacture modern rockets and missiles.
