Back to basics: Make in India and Defence Indigenisation
Make in India is a government initiative to encourage domestic manufacturing, including defence production, to reduce reliance on imports. Defence indigenisation involves designing, developing, and producing military equipment within the country, enhancing self-reliance and strategic autonomy. Indigenous warship construction strengthens maritime security by enabling tailored capabilities suited to India's strategic needs.
Practice: MCQ, Mains and revision
