In a significant advancement for India’s indigenous defence capabilities, the Defence Research and Development Organisation (DRDO) has commenced limited serial production of the Phase-II Ballistic Missile Defence (BMD) interceptor, the AD-1 missile. This long-range interceptor, designed to neutralize both ballistic missiles and aircraft, boasts a large kill altitude bracket, enabling it to engage targets in both low exo-atmospheric and endo-atmospheric environments. The move to limited production is aimed at facilitating more extensive trials, marking a critical step toward operational deployment and enhancing India’s strategic defence against aerial threats.
The AD-1 missile is a cornerstone of India’s Phase-II BMD program, which seeks to develop a robust, multi-layered defence system capable of countering a wide range of ballistic missile threats. Unlike its predecessors in the Phase-I BMD system—such as the Prithvi Air Defence (PAD) and Advanced Air Defence (AAD) missiles—the AD-1 is designed to operate across a broader altitude range, making it a versatile asset for both high-altitude exo-atmospheric intercepts (outside the Earth’s atmosphere) and lower-altitude endo-atmospheric engagements (within the atmosphere). This dual capability positions the AD-1 as a critical tool for intercepting long-range ballistic missiles during their mid-course and terminal phases, as well as engaging hostile aircraft in a theatre air defence role.
Propelled by a two-stage solid motor, the AD-1 is equipped with indigenously developed technologies that set it apart as a cutting-edge system. Its advanced control system, combined with sophisticated navigation and guidance algorithms, ensures precise targeting and high accuracy. The missile’s ability to intercept targets across a large altitude bracket enhances India’s defensive flexibility, allowing it to counter diverse threats—from intermediate-range ballistic missiles (IRBMs) to tactical aircraft—in a single platform.
The first successful flight test of the AD-1 missile was conducted in November 2022 from the Abdul Kalam Island off the coast of Odisha. During the test, the missile demonstrated its ability to intercept a simulated ballistic missile target at a high altitude, validating its propulsion, guidance, and interception capabilities. Subsequent trials have focused on testing the missile against a variety of targets, including those simulating enemy aircraft and missiles with different trajectories and speeds. By moving to limited production, the DRDO aims to conduct more frequent and complex trials, potentially involving salvo launches, intercepts in dense electronic warfare environments, and engagements at varying altitudes.
The development and eventual deployment of the AD-1 missile hold profound implications for India’s national security, particularly in the context of its regional threat environment. With neighbors like China and Pakistan possessing advanced ballistic missile arsenals—ranging from short-range tactical missiles to intercontinental ballistic missiles (ICBMs)—India faces a multifaceted aerial threat. The AD-1, as part of the Phase-II BMD system, enhances India’s ability to protect its key population centers, military installations, and strategic assets from such threats.
The missile’s dual role as both a ballistic missile interceptor and an anti-aircraft system adds significant flexibility to India’s air defence architecture. While the Phase-I BMD system, comprising the PAD and AAD missiles, provided a foundational capability against ballistic missiles with ranges up to 2,000 km, the Phase-II system, with the AD-1, aims to counter longer-range threats (beyond 5,000 km) and more sophisticated missile technologies, such as those with multiple independently targetable reentry vehicles (MIRVs) or hypersonic glide vehicles. Additionally, the AD-1’s ability to engage aircraft complements India’s existing surface-to-air missile systems like the S-400 and Akash, creating a layered defence network capable of addressing diverse aerial challenges.
