Strategic autonomy and supply chain resilience in defence manufacturing: a key GS3 and Science & Tech angle.

Why in news

Experts at the SRM Presents The Hindu Semiconductor Summit 2026 warned that India's network-centric weapons, including Sudarshan Chakra and BrahMos, are vulnerable due to a reliance on imported semiconductors.

Background

Experts urged end-to-end domestic manufacturing of 3-nanometre chips by 2030-35. The Semiconductor Laboratory (SCL) currently uses 180-nanometre technology, while the Tata fab in Gujarat will introduce 40-nanometre nodes.

Facts for Prelims

FactThe target for domestic manufacturing of 3-nanometre chips is set for 2030-35.

Prelims practice question

With reference to India's semiconductor manufacturing, consider the following statements:

The target for domestic manufacturing of 3-nanometre chips is set for 2020-25.
The Semiconductor Laboratory (SCL) currently utilizes 40-nanometre technology.
The Tata fab in Gujarat is slated to introduce 40-nanometre nodes.

Which of the statements given above is/are correct?

(a)1 only
(b)3 only
(c)2 and 3 only
(d)1, 2 and 3

Show answer

Answer: (b) 3 only — Statement 3 is correct. Statement 1 is incorrect: The target is set for 2030-35. Statement 2 is incorrect: The SCL currently utilizes 180-nanometre technology.

For Mains

Q. Discuss the strategic implications of India's reliance on imported semiconductors for its defence manufacturing and the necessity of a domestic semiconductor ecosystem.

Dimensions to cover in your answer

Supply chain vulnerability: High dependence on foreign-sourced chips for critical network-centric weapons systems
Technological gap: Disparity between current 180nm/40nm capabilities and the required 3nm nodes for advanced electronics
Strategic autonomy: Risks of geopolitical leverage over India's defence technology through semiconductor supply chains
