Opening

The recent conflict with Pakistan has demonstrated the immense utility of missile defence systems both in defensive (S-400) and offensive (Agni-Prithvi etc.) standpoints.

India has a multi-pronged missile defence system based on principles of proximity, tiered response, distance of reach, range and nature of warhead.

Body · points and prose

Diagram
India's progress → Procurement through missile diplomacy: e.g. Barak from Israel → Indigenous R&D by DRDO → Long range multi-tiered defence → Agni: Short range, surface to air → Trishul → Prithvi: ICBM → Nag → anti-tank missile

Limitations

→ Dependence on forgn actrs. Eg. S-400 obtained from Russia. → Lack of defence indigenization → Lack of cohesive national security doctrine of on missile use

Close · a way forward

Hence, while India has made an initial foray into missile defense systems, a lot more needs to be done to gain self-sufficiency and multi-modal competency.
