As geopolitical tensions simmer along its borders, India has fortified its skies with a formidable array of air defense systems, blending cutting-edge indigenous technology with advanced foreign acquisitions. From countering Pakistan’s drones to neutralizing China’s ballistic missiles, India’s multi-layered air defense architecture is designed to protect its vast 3.287 million sq km territory and 1.4 billion citizens. Here’s an in-depth look at the systems safeguarding India’s airspace.
A Robust Multi-Layered Defense
India’s air defense strategy integrates long-, medium-, short-, and very short-range systems, operated by the Indian Army, Air Force, and Navy. These systems, supported by sophisticated command-and-control networks, are tailored to tackle a spectrum of threats, including fighter jets, cruise missiles, ballistic missiles, and drones.

Long-Range Protection: S-400 and BMD
At the apex of India’s air defense is the S-400 Triumf, a Russian-supplied system capable of engaging targets up to 400 km away. Renamed “Sudarshan” in Indian service, the S-400 can neutralize aircraft, missiles, and drones at speeds up to Mach 14, tracking 300 targets simultaneously with its advanced AESA radar. Three of the five regiments ordered in a $5.43 billion deal have been delivered, bolstering defenses along the China and Pakistan borders.
Complementing the S-400 is India’s indigenous Ballistic Missile Defence (BMD) program, a two-tiered system to intercept ballistic missiles launched from up to 5,000 km away. The Prithvi Air Defence (PAD) operates at 50–80 km altitudes, while the Advanced Air Defence (AAD) engages threats at 15–30 km. Successfully tested since 2006, the BMD is poised for deployment around Delhi, with Phase 2 aiming to counter longer-range missiles by 2028.
Medium-Range Backbone: Akash and Barak-8
The Akash SAM system, developed by DRDO, is India’s answer to versatile medium-range defense. With a range of 45 km (Akash-1S) and up to 80 km (Akash-NG), it neutralizes fighter jets, cruise missiles, and ballistic missiles. Two regiments are operational, protecting vital areas, with Akash-NG’s 2021 trials showcasing enhanced agility against agile threats.
The Indo-Israeli Barak-8 system, with a 70–100 km range, is a cornerstone for both the Air Force and Navy. Deployed aboard INS Vikrant and at airbases, its EL/M-2084 AESA radar provides 360-degree coverage, making it ideal against subsonic cruise missiles like Pakistan’s Babur.
Short-Range and Tactical Defense: QRSAM and SPYDER
For rapid-response defense, the Quick Reaction Surface-to-Air Missile (QRSAM), with a 25–30 km range, counters drones and low-flying aircraft. Successfully tested in 2022, it is being inducted to protect forward positions along the Line of Control. The Israeli SPYDER system, with Python-5 and Derby missiles, enhances short-range defense for airbases, engaging targets up to 35 km away.
Last Line of Defense: VSHORADS and CIWS
The Very Short-Range Air Defence System (VSHORADS), an indigenous man-portable system, has emerged as a game-changer. Recent trials in 2024–2025 demonstrated its “hit-to-kill” capability against drones and helicopters at 6–8 km ranges. Meanwhile, the Russian Igla-S, procured in 2024, serves as a stopgap, with some units assembled locally by Adani Defence.
Naval assets rely on the AK-630, a close-in weapon system (CIWS) firing 5,000 rounds per minute to counter missiles within 4 km, and the indigenous SRSAM, protecting carriers like INS Vikrant.
Emerging Technologies and Indigenization
India’s push for self-reliance is evident in projects like Project Kusha, a DRDO-developed long-range SAM system akin to the S-400, targeted for 2028–29. The Akashteer system, inducted in 2024, automates air defense coordination, while high-power radars (HPR) worth ₹5,700 crore enhance detection of stealthy targets.
The Integrated Air Command and Control System (IACCS), managed by the Air Force, provides a real-time picture of India’s airspace, reducing response times. Future systems, including laser-based weapons, aim to intercept missiles in their boost phase, though deployment is a decade away.
Strategic Context and Recent Successes
India’s air defense faces unique challenges due to its scale and dual-front threats from Pakistan and China. Recent tensions, including the Pahalgam attack, underscored the need for robust systems. In May 2025, the S-400 and Integrated Counter UAS Grid successfully neutralized Pakistani drones and missiles during a retaliatory strike, proving their operational prowess.
Unlike Israel’s Iron Dome, which focuses on short-range rockets, India’s systems address a broader threat spectrum. The Akash is often compared to Iron Dome, but systems like the S-400 and BMD provide strategic depth, tailored to India’s vast geography.
Challenges and the Road Ahead
Despite progress, India faces gaps in system numbers and integration. Delays in indigenous projects like VSHORADS-NG prompted emergency procurements, and seamless connectivity between Air Force, Army, and Navy systems remains a priority. The proposed NASAMS-II from the U.S., with a 40 km range, could bolster Delhi’s defenses if negotiations conclude.
With a mix of proven systems and ambitious indigenous programs, India’s air defense is a testament to its strategic foresight. As DRDO and private players like Larsen & Toubro ramp up production, the nation is poised to secure its skies against evolving threats, ensuring a resilient shield for the future..
