Russia has proposed a transfer of technology (ToT) to India for the S-400 air defence system, alongside an offer for local manufacturing of system components. This offer comes as Russia faces delays in delivering the final two squadrons of the S-400 system to the Indian Air Force (IAF).
The proposal is intended to allow India to produce S-400 parts domestically, facilitating both replenishment of existing systems and potential future expansion of its inventory.
In 2018, India contracted to purchase five squadrons of the S-400 system from Russia for approximately $5.43 billion. Three of these squadrons have been delivered and are currently operational, strategically positioned along India's northern and eastern borders.
These deployed systems have been integrated into India's air defence network and have been utilized in training exercises, significantly improving the country's ability to defend against aerial threats.
However, the delivery schedule for the remaining two squadrons is unclear, with ongoing geopolitical and logistical difficulties related to the conflict in Ukraine cited as contributing factors.
In an effort to address India's increasing focus on defence self-sufficiency, Russia has put forward the ToT proposal. This would enable the local production of crucial components for the S-400 system.
This approach supports India's broader "Make in India" initiative, which aims to boost domestic defence production capabilities and lessen the country's dependence on international arms suppliers.
The successful implementation of this offer could lead to the establishment of an Indian production line for S-400 components, bolstering air defence readiness and ensuring a consistent supply of vital missile parts.
The S-400, known in NATO reporting as the SA-21 Growler, is a mobile, surface-to-air missile (SAM) system capable of engaging aircraft, UAVs, cruise missiles, and even ballistic missiles.
The potential acceptance of Russia's ToT offer would present several complex considerations. These include the effective integration of the transferred technology, the establishment of localized supply chains for necessary materials, and the negotiation of intellectual property rights.
Additionally, the wider geopolitical landscape, including sanctions imposed on Russia by Western nations, could pose challenges to the sourcing of essential components directly from Russian manufacturers. These factors will likely be a key part of the discussion and approval process.
While evaluating the Russian proposal, India continues to develop its own indigenous long-range air defence system, known as Project Kusha, managed by the Defence Research and Development Organisation (DRDO).
Project Kusha seeks to create a system with performance characteristics similar to the S-400. The DRDO project envisions a multi-layered missile defence architecture, fully integrated with India's existing air defence infrastructure, ultimately reducing the nation's reliance on imported defence systems. The system, with an expected range exceeding 350 km, is anticipated to be deployable by 2028-29.
