As its name suggests, the Aerospace and Defence Industry works in two major sectors: Aerospace, which comprises the production, sale and service of aircrafts, space missiles, aircraft engines, propulsion units and related parts; and Defence, which is dependent on the nation’s need for weapons and military technology designed to operate on land, sea, and in the air. This industry is one of the most strategically important sectors of India and is estimated to reach $70 billion by 2030.
