The Defence Procurement Board (DPB) has cleared a proposal by the Indian Air Force (IAF) to acquire five additional S-400 Triumf air defence systems from Russia, according to officials familiar with the development. The decision comes at a time when evolving conflicts in West Asia are increasingly characterised by the use of ballistic missiles and kamikaze drones.
The board, chaired by Defence Secretary Rajesh Kumar Singh, approved the IAF’s proposal and forwarded it to the Defence Acquisition Council (DAC), headed by Defence Minister Rajnath Singh, for Acceptance of Necessity (AoN). Once the DAC grants AoN, a cost negotiation committee will be constituted to determine the financial terms of the acquisition. The proposal will subsequently require final approval from the Cabinet Committee on Security (CCS) following examination by the finance ministry.
India currently operates three S-400 systems, with two more expected to be inducted later this year. The system’s operational effectiveness was highlighted during Operation Sindoor, where it played a key role in maintaining air dominance. On May 10, 2025, India launched a precision strike using the BrahMos missile system, targeting the Northern Command and Control network of the Pakistan Air Force at Chaklala Airbase in Rawalpindi. The S-400 shield ensured that adversarial fighter aircraft, airborne early warning platforms and electronic intelligence assets were unable to challenge Indian operations during the engagement.
In parallel, the defence ministry is awaiting proposals from the IAF and the Indian Army to procure 13 units of the Pantsir-S1 self-propelled air defence system. Of these, 10 are intended to provide layered protection for the S-400 assets, while three will be deployed by the Army to counter cruise missiles, attack helicopters, armed drones, loitering munitions and short-range rockets along sensitive borders.
While negotiations for the additional S-400 units are yet to begin, officials indicate that all five systems are likely to be acquired through outright purchase. Maintenance, overhaul and repair responsibilities are expected to be entrusted to Indian private sector entities, enhancing domestic participation in sustainment.
The procurement model for the Pantsir-S1 systems is expected to differ. An initial batch will be acquired under the fast-track route to address urgent operational requirements, followed by phased domestic production by Indian private firms. The Pantsir system is currently operated by the United Arab Emirates and has demonstrated effectiveness against Iranian-origin kamikaze drones in recent conflict scenarios.
India’s expansive geography — including an 11,000-km coastline and active western and northern borders — necessitates a robust, multi-layered air defence architecture. The growing proliferation of long-range missiles in the Indian subcontinent and West Asia, along with the increasing deployment of low-cost loitering munitions and kamikaze drones, has reinforced the urgency of strengthening anti-ballistic and air defence capabilities.
Recent geopolitical developments, including tensions involving Iran and the United States, have further underscored the strategic value of advanced missile defence systems.
Additionally, the export of affordable unmanned aerial systems by regional players has introduced new dimensions of saturation warfare, prompting India to accelerate efforts to fortify its aerial shield against emerging threats.
