Baba Kalyani who has said on record said the 7 year procurement cycle is unsustainable for pvt sector players
As for the small procurement cycle, that's only because orders are small today, that will change with indigenous systems
He was talking A 7 year time gap between RfP, trials, commercial bidding, multiple approvals,etc in the context of the IAs artillery acquisition plan. We all know that piecemeal orders kill economies of scale, and affect margins.
That's just dependent on India's increasing funds
When was the last time the armed forces returned unspent acquisition funds to the govt at the close of a given financial year? More money is not the answer. It's all about planning requirements long-term, defining timelines, and assuring minimum order quantities (just like farmers insist on MSP for their produce)
