Explained: Why India Is Indigenising Parts Used in Tejas, Su-30MKI and T-90 Tanks

New Delhi: Defence indigenisation is becoming a key part of India’s long-term military strategy. The Ministry of Defence has recently added 405 new defence items to its Positive Indigenisation List (PIL), aiming to reduce dependence on foreign suppliers and strengthen domestic manufacturing. While many people focus on fighter jets, tanks and missiles, the latest move targets smaller but critical components that keep major military platforms operational.

What Is the New Defence Indigenisation List

The Ministry of Defence has included 405 defence items in its latest Positive Indigenisation List. These items include line replaceable units, sub-systems, sub-assemblies, spare parts, components and raw materials.

The objective is simple: increase domestic sourcing and reduce India’s reliance on imported defence equipment over time. According to official government policy, these items will gradually be procured from Indian industry instead of foreign suppliers.

Defence Indigenisation: Why Is India Focusing on Small Components

Modern military platforms are made up of thousands of parts. A fighter aircraft, tank, helicopter or warship can become unavailable if even one critical component is not available when needed. By manufacturing these components in India, the armed forces can improve maintenance, repairs and long-term operational readiness.

Experts believe this approach strengthens supply-chain security and reduces vulnerabilities during emergencies or conflicts.

What Does Defence Indigenisation Really Mean

Many people assume indigenisation means an entire military platform is built completely in India.

That is not always true.

Defence indigenisation focuses on increasing the Indian share of manufacturing, technology, components and support systems over time. The government’s strategy is to steadily reduce foreign dependence rather than achieve 100% localisation immediately.

Tejas Fighter Jet: A Good Example

The Light Combat Aircraft (LCA) Tejas has been developed and manufactured in India. Its indigenous content has increased significantly over the years. However, some important systems, including the engine, still originate from foreign suppliers. This shows that indigenisation is a gradual process where more components are replaced by Indian-made alternatives over time.

Why Su-30MKI Is Important

The Su-30MKI remains one of the Indian Air Force’s most important fighter aircraft. Although a large amount of manufacturing and maintenance work takes place in India, the aircraft still depends on several imported components. The latest indigenisation list includes parts and systems linked to the Su-30MKI. This can help improve availability and reduce future dependence on foreign supply chains.

Defence Indigenisation: Focus on the T-90 Battle Tank

The T-90 is one of the Indian Army’s main battle tanks. The new list also includes components associated with the T-90 platform. The aim is not to replace the entire tank but to ensure that more spare parts, maintenance items and support equipment are sourced from Indian companies. This can improve long-term sustainability and operational readiness.

What is the Role of SRIJAN Portal in Defence Indigenisation

The government’s SRIJAN portal plays an important role in the indigenisation programme. It helps identify imported defence items and connects them with Indian manufacturers capable of producing them domestically.

The platform supports collaboration between defence companies, MSMEs, startups and public-sector enterprises. This creates opportunities for a larger domestic defence manufacturing ecosystem.

Defence Indigenisation: Why MSMEs Are Critical

Small and medium enterprises (MSMEs) are expected to play a major role in this initiative. Not every company needs to build a fighter aircraft or tank.

Many businesses can contribute by manufacturing specialised components, electronic systems, sensors, mechanical assemblies and spare parts. This approach expands India’s defence industrial base and creates new business opportunities.

Strategic Importance During Wartime

Supply-chain security becomes extremely important during conflicts. Military operations consume not only missiles and ammunition but also spare parts, electronics and replacement components. If imported parts become unavailable, military readiness can be affected.

Domestic production helps ensure that equipment remains operational even during supply disruptions.

Expert Analysis: A Long-Term Defence Strategy

The latest Positive Indigenisation List is not just about replacing imports.

It reflects a broader strategy to create a strong domestic defence ecosystem capable of supporting India’s military requirements for decades.

The focus on smaller components may appear less dramatic than building a new fighter jet, but it can deliver greater long-term benefits.

By strengthening local supply chains, India can improve military readiness, create industrial opportunities and enhance strategic autonomy.
