This chapter examines defense planning in the Indian military. It begins with a conceptual discussion on the role of civilians in defense planning, mainly by examining the experience of other democracies. Next, it describes the history of defense planning in India, focusing on the formulation and implementation of five-year defense plans. There are three main arguments in this chapter. First, effective defense planning requires a close partnership between civilians and the military. Second, defense planning in India is marked by a lack of civilian guidance and institutional discordance, creating friction in civil–military relations. To an extent, this is because of a lack of expertise, on the part of civilians, and an institutional design that creates strong civil–military silos. Third, notwithstanding the above, there have been periodic attempts at reforming defense-planning structures. Progress has been achieved in some sectors, but much remains to be done.
