Indian Air Force Starts SDR Upgrade for 36 MiG-29 Aircraft Across Multiple Bases

The Indian Air Force (IAF) has initiated a major communication upgrade programme for its MiG 29 fighter fleet, taking another step towards strengthening its network centric combat capabilities. The latest programme involves integrating Software Defined Radios (SDRs) across 36 MiG 29 aircraft, enabling faster, more secure and reliable communication during operations while supporting future battlefield requirements.

The project will cover 29 MiG 29 fighter aircraft and 7 trainer variants, with the integration work scheduled to be carried out over the next 18 months in multiple phases. The programme forms part of the Indian Air Force's continued efforts to modernise its existing combat fleet while maintaining operational readiness.

The development comes as the Indian Air Force continues to strengthen its combat capabilities through aircraft upgrades, missile acquisitions and advanced defence technologies, supporting India's long term military modernisation plans.

IAF To Upgrade 36 MiG 29 Aircraft

The Indian Air Force has initiated the integration of Software Defined Radios (SDRs) on 36 MiG 29 aircraft, including 29 fighter jets and 7 trainer aircraft. The programme will utilise Netcor 1 and Netcor 2 SDR systems, which will be connected through the MIL 1553 data bus to provide enhanced Network Centric Operations (NCO) capability across the fleet.

Existing Electronic Warfare Systems To Remain Unaffected

The Indian Air Force has specified that the integration of the new communication systems must not affect the aircraft's existing Electronic Warfare (EW) equipment. The D 29RWJ and Talisman NTE 29 systems will continue to operate without any changes after the SDR installation, ensuring that the aircraft's current electronic warfare capability remains fully operational.

Defence Modernisation Continues

The latest MiG 29 upgrade reflects the Indian Air Force's continued focus on improving operational capability through communication and avionics modernisation. Alongside aircraft upgrades, India has accelerated investments in indigenous defence manufacturing, advanced weapons, electronic warfare systems and military communication technologies.

Companies such as HAL, BEL, Bharat Dynamics, Mazagon Dock and Solar Industries continue to remain in focus as India's defence ecosystem expands. Investors are also tracking recent developments such as the ₹150 crore tactical communication equipment order secured by Neueon Corporation and the proposed ₹2,000 crore MALE drone programme involving HAL, Adani Defence, Tata Advanced Systems and Solar Industries.

Investor Takeaways

The integration of Software Defined Radios across 36 MiG 29 aircraft represents another important step in the Indian Air Force's ongoing fleet modernisation programme. The project will enhance communication capability across the MiG 29 fleet while ensuring that existing electronic warfare systems remain unaffected during and after integration.

The programme also highlights India's continued emphasis on strengthening defence preparedness through technology upgrades and indigenous capability development, which remains a long term positive for the country's defence ecosystem.
