Speaking at a seminar on the sidelines of Vibrant Gujarat Summit here, he said a USD 20 billion import bill for defence was not affordable.
"Such a huge import bill has undesirable consequences for the economy, development and unemployment in the country," he said, adding that for strategic reasons too the country should not be dependent on defence imports.
In the light of this background, the Minister said, the "government hopes to come up with a document in 2-3 months on a suitable model for defence manufacturing and procurement".
He said defence manufacturing will get a major thrust in line with 'Make in India' policy.
He also stated that his ministry would soon be in a position to decide which items should be manufactured in India and gradually that list would be increased over a period of time.
Later, Parrikar said the Defence Procurement Procedure (DPP) 2015 will have an "industry friendly" approach for defence production.
India has recently taken steps like relaxed foreign direct investment norms to boost local manufacturing.
Observing that there are "some gaps" in the current DPP, he said "since we are the only consumer and the buyer so whenever you deal with anyone there has to be guarantee of purchase from Make in India. Unless, you guarantee a purchase on successful production, there is no chance of anyone coming forward".
Current policies, Parrikar added, are "too cumbersome and bureaucratic nightmare" for the industry and needs to be reviewed.
He hoped that with change in the business climate and setting up of new guidelines and principles, the process of local investment will start.
When asked if government would focus on buying equipment from private sector, he said it is "not just throwing something at private (sector), it should also interest the defence".
"However, after spending crores in curtain projects the goal post suddenly shifts. Therefore, there is a need for total overhaul in conceptualising and thinking with regard to defence manufacturing and procurement," he said.
Once the concepts are clear, Parrikar said "we can then engage the Gujarat Government and involve them in the process of defence production".
