The recent strengthening of India’s air defence capabilities comes in response to key events surrounding Operation Sindoor, held on May 7, 2025. A Lieutenant Colonel, stationed in Jaisalmer during the operation, recounted the heightened vigilance among forces along the India-Pakistan border. This operation showcased a significant escalation in military action, resulting in India’s targeted strikes on nine terror infrastructure sites in Pakistan, which led to a brief but intense five-day military engagement.

India’s defences were reportedly effective, preventing major damage during incoming drone and missile waves launched by Pakistan in retaliation. The operation highlighted the effectiveness of India’s multi-layered defence strategy, which included the use of systems such as the Russian S-400 and indigenous Akash missiles, as well as a counter-drone grid. No major setbacks occurred on the Indian side of the border, demonstrating the robustness of the defence structures in place.

Although successful, the episode illuminated the evolving nature of warfare, especially the growing reliance on inexpensive drones that can challenge advanced defence mechanisms. Experts believe that layered and adaptable air defence systems are now crucial to counter modern aerial threats effectively, an issue brought to the forefront by the aerial confrontations seen in various global conflicts.

Enhancements to Defence Systems and Structures

In the wake of Operation Sindoor, the Indian government has moved quickly to rectify any vulnerabilities identified during the conflict. Significant strategic decisions have included the expansion of existing air defence systems, notably the addition of five new S-400 Triumf squadrons approved by the Defence Acquisition Council. These new units will complement the initial five contracted in 2018, enhancing India’s ability to monitor and engage potential aerial threats more effectively.

Each S-400 battery is equipped to simultaneously track numerous targets and intercept multiple incoming threats, providing a networked umbrella across the western and eastern borders. Meanwhile, mid-range support systems like the Akash missile are also undergoing rapid enhancement to supplement existing capabilities. These investments aim to create a well-rounded approach to aerial defence that does not rely solely on high-cost solutions.

Additionally, older air defence guns are being modernised for use against drone swarms. As the military pivots toward low-cost, efficient systems, plans are in place to upgrade existing artillery and procure next-generation air defence guns capable of countering modern aerial threats while optimising sustainability and affordability.

Strategic Innovations Incorporating AI and Indigenous Development

Central to India’s future air defence strategy is the launch of Mission Sudarshan Chakra, announced in August 2025. This initiative aims to integrate various military technologies, such as radars and missile systems, into a cohesive, AI-powered framework that enhances situational awareness and command effectiveness across the airspace.

Further contributing to these advancements is Project Kusha, which is focused on developing an indigenous long-range surface-to-air missile system. The project is designed to complement existing S-400 capabilities and aims for deployment by 2030, enhancing India’s strategic capabilities significantly. Together, these initiatives seek to create a comprehensive and economically sustainable air defence architecture, addressing modern warfare challenges effectively.

Amidst these advancements, the armed forces are also investing in counter-drone technology to counteract the increasingly prevalent threat posed by drones. This includes the acquisition of advanced systems capable of neutralising aerial threats rapidly. The evolving landscape necessitates continuous updates, particularly as defence strategies increasingly integrate civilian aviation safety alongside military readiness.
