The Defence Research and Development Organisation of India has conducted a successful maiden flight test of the Kusha Long-Range Surface-to-Air Missile, marking a significant milestone in the nation’s indigenous defence capabilities.
On July 23, 2026, India’s Defence Research and Development Organisation (DRDO) executed the first flight-test of the Kusha Long-Range Surface-to-Air Missile (LRSAM) from the Integrated Test Range (ITR) located at Dr APJ Abdul Kalam Island, off the coast of Odisha. The missile successfully intercepted a high-speed electronic target that simulated a next-generation aerial threat, underscoring India’s growing prowess in indigenous defence technology.
The successful trial not only demonstrates India’s advanced capabilities in missile technology but also signifies its entry into a select group of nations capable of designing and deploying long-range air defence systems independently. Union Defence Minister Rajnath Singh emphasized the importance of this test, stating, “The capability to develop long-range surface-to-air missile systems is possessed only by a handful of nations. This test eliminates foreign import dependency for such critical strategic systems and signifies a giant leap in the nation’s air defence posture.”
Details of the Maiden Test
The Kusha missile was developed under Project Kusha, also known as the Extended Range Air Defence System (ERADS). The initiative aims to establish a comprehensive, multi-layered air defence shield across Indian airspace by the end of the decade, thereby reducing reliance on foreign systems. Official statements from the Ministry of Defence confirmed that all mission objectives were met during the test.
Key details from the flight test include:
- Target Profile: An advanced electronic target simulating a low-radar-cross-section stealth jet or high-altitude cruise missile traveling at supersonic speeds.
- Tracking and Engagement: Multi-Function Fire Control Radars and 3D Long-Range Observation Radars continuously tracked the target, providing mid-course guidance updates via secure datalink to the missile.
- Kill Mechanism: The test validated the hybrid radio-frequency and infrared terminal seeker performance, alongside the optical proximity fuse and pre-fragmented warhead.
Project Kusha’s Strategic Importance
Project Kusha was formally sanctioned by the Cabinet Committee on Security (CCS) in May 2022, receiving an Acceptance of Necessity (AoN) from the Defence Acquisition Council (DAC) in September 2023, with a budget allocation of Rs 21,700 crore (approximately $2.6 billion) for the procurement of five squadrons for the Indian Air Force (IAF).
The Kusha system is designed to include three distinct interceptor missiles (M1, M2, and M3) operated from common, mobile Transporter Erector Launchers (TELs), providing a layered defence approach:
- M1 Interceptor: Range of 120-150 km, optimized for medium-to-long-range engagements against tactical strike aircraft and low-flying cruise missiles.
- M2 Interceptor: Range of 250 km, designed to counter high-altitude jammers and strategic bombers.
- M3 Interceptor: Range of 350-400 km, capable of targeting airborne early warning systems and ballistic threats.
The Kusha missile system features advanced propulsion and guidance technologies, achieving speeds exceeding Mach 5.5 and incorporating a sophisticated guidance suite that integrates inertial navigation and satellite-assisted corrections for enhanced accuracy.
Integration into India’s Air Defence Framework
Project Kusha is intended to serve as the outer layer of India’s multi-tiered air defence grid, complementing existing systems such as the S-400 Triumf and various short-range air defence systems. The Kusha system operates within the Indian Air Force’s Integrated Air Command and Control System (IACCS), which connects civilian and military radars for improved coordination and effectiveness.
By bridging the gap between medium-range systems and strategic anti-ballistic missile interceptors, Kusha aims to enhance the overall defensive posture against aerial threats. The initiative is part of the broader Mission Sudarshan Chakra, which integrates different layers of air defence to create a robust shield over strategic installations and border regions.
Comparison with Global Systems
In evaluating Kusha’s capabilities, it is essential to compare it with other leading air defence systems globally, including Russia’s S-400 Triumf, the United States’ MIM-104 Patriot, and China’s HQ-9B. Notably, Kusha’s M3 variant boasts a range of 400 km, exceeding the capabilities of many contemporary systems.
Key advantages of the Kusha system include:
- Superior radar technologies that enhance target detection against stealth threats.
- A comprehensive multi-function radar system providing 360-degree coverage.
- Independence from foreign supply chains, ensuring consistent domestic maintenance and upgrades.
Future Developments
Looking ahead, Project Kusha represents a collaborative effort between government research organizations and the private sector, with significant participation from companies like Bharat Electronics Limited (BEL) and Bharat Dynamics Limited (BDL). As production ramps up, the initiative aims to produce between 300 to 400 interceptor missiles annually by 2032, which will further solidify India’s air defence capabilities.
The successful test of the Kusha missile is expected to shift the balance of air power in South Asia, compelling adversarial aircraft to operate at greater distances from Indian borders and enhancing national security. Additionally, there are plans to develop a naval version of the Kusha missile for deployment on future naval platforms, further expanding its strategic reach.
With the Kusha missile system poised for operational deployment, India aims to position itself as an exporter of advanced surface-to-air missile systems, catering to nations seeking alternatives to existing Western and Russian technologies.
