Project Kusha is a programme under the Defense Research and Development Organization (DRDO), for developing the Extended Range Air Defence System (ERADS), also referred to as XRSAM [lower-alpha 1] or PGLRSAM [lower-alpha 2] . The goal is to design a transportable, long-range surface-to-air missile system. The missile system will consist of at least three types of interceptors and is expected to be deployed by the Indian Air Force and Indian Navy by 2028–2029. [1] [5] [6]
It will supplement the Indo-Israeli Barak 8, Russian S-400 and Indian Ballistic Missile Defence System in the Indian armed forces.
The missile system might used to bridge the gap between the MR-SAM (80 km) and S-400 (400 km). It is being developed as an area-defence system. The Indian Air Force (IAF) will be the lead agency for this air defence system. [7] [2]
The project was cleared for development by the Cabinet Committee on Security (CCS) in May 2022, and was granted Acceptance of Necessity (AoN) by the Ministry of Defence (MoD) in September 2023 for procuring five of its squadrons for the IAF for ₹ 21,700 crore (US$2.6 billion). [2]
The naval version of the missile might be also developed to supplement the LR-SAM missile in the Indian Navy. [4] [8]
As of August 2024, DRDO is about to start the fabrication process of 5 M1 missiles (range of 150 km). DRDO has also placed order for 20 sets of airframes, 20 sets of rocket motors, 50 sets of kill vehicles (warhead), onboard & ground transceivers for telemetry. The missiles are expected to begin testing in early 2025. [9] [10]
The missile system includes at least three types of interceptor missiles. The missiles will have ranges of 150 km, 250 km and 350 km. This system will also feature advanced long-range surveillance and fire control radars. [5] [2] The air defence system will be capable of detecting and destroying enemy assets like cruise missiles, stealth fighter jets, and drones at around 250 km range and larger aircraft like airborne early warning and control (AEW&CS) at a range of 350 km. [7] The missiles may also possess short or medium range BMD capabilities. It will have a single-shot kill probability more than 80% and not less than 90% probability in salvo launch mode. [1] [2]
The missile batteries will be able to “interact” with the IAF’s integrated air command and control system (IACCS). It is a fully-automated air defence network operated by Indian Air Force which will be built to combine numerous military and civilian radars with each other in Indian airspace to make the Air Defence system more efficient and reliable. [1]
According to a report, the naval variant exceeding 250 km-range missile will be capable of intercepting anti-ship ballistic missile (ASBM) with a speed of Mach 7. [6]

The Integrated Guided Missile Development Programme (IGMDP) was an Indian Ministry of Defence programme for the research and development of the comprehensive range of missiles. The programme was managed by the Defence Research and Development Organisation (DRDO) and Ordnance Factories Board in partnership with other Indian government political organisations. The project started in 1982–83 under the leadership of Abdul Kalam who oversaw its ending in 2008 after these strategic missiles were successfully developed.
Akash is a medium-range mobile surface-to-air missile (SAM) system developed by the Defence Research and Development Organisation (DRDO) and produced by Bharat Dynamics Limited (BDL). Surveillance and Fire control radar, tactical control and command center and missile launcher are developed by Bharat Electronics Limited (BEL), Tata Advanced Systems Limited and Larsen & Toubro. The Akash missile system can target aircraft up to 45 km (28 mi) away. It has the capability to neutralise aerial targets like fighter jets, cruise missiles and air-to-surface missiles. It is in operational service with the Indian Army and the Indian Air Force.
Astra is an Indian family of all weather beyond-visual-range air-to-air missile, developed by the Defence Research and Development Organisation. Different missiles of this family are capable of engaging targets at varying distances of 500 m (0.31 mi) up to 340 km (210 mi). Astra Mk-1 has been integrated with Indian Air Force's Sukhoi Su-30MKI and will be integrated with Dassault Mirage 2000, HAL Tejas and Mikoyan MiG-29 in the future. Limited series production of Astra Mk-1 missiles began in 2017.
The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect India from ballistic missile attacks. It was launched in 2000 after the Kargil War by the Atal Bihari Vajpayee government. Testing was carried out and continuing as of 2006, and the system was expected to be operational within four years according to the head of the country's missiles development programme, Vijay Kumar Saraswat.
The central acquisition radar (3D-CAR) is a 3D radar developed by the Defence Research and Development Organisation (DRDO) for use with Akash Surface-to-air missiles and is capable of tracking 150 targets.
Swordfish is an Indian active electronically scanned array (AESA) long-range tracking radar specifically developed to counter ballistic missile threat. It will be a part of the Indian Ballistic Missile Defense Programme. First testing of this radar was in March 2009. Main aim of the test was to validate the capabilities of the Swordfish Long Range Tracking Radar (LRTR). "The missile to be hit will be fired from a longer distance than it was in the earlier test. DRDO tested whether the radar could track the incoming missile from that distance or not," said a member of the project. This radar is an acknowledged derivative of the Israeli EL/M-2080 Green Pine long range radar, which is the critical component of that country's Arrow missile defense system. However, it differs from the Israeli system as it employs Indian Transmit Receive modules, signal processing, computers and power supplies. It is also more powerful than the base Green Pine system and was developed to meet India's specific BMD needs.
The Indian Air Force has been undergoing a modernization program to replace and upgrade outdated equipment since the late 1990s to meet modern standards. For that reason, it has started procuring and developing aircraft, weapons, associated technologies, and infrastructures. Some of these programs date back to the late 1980s. The primary focus of current modernization and upgrades is to replace aircraft purchased from the Soviet Union that currently form the backbone of the air force.
India has studied, produced and used various strategic and tactical missile systems since its independence. Decades long projects have realised development of all types of missile systems including ballistic, cruise, anti-ship, air-defence, air-to-air and anti-missile systems. India is one of seven countries in the world with intercontinental ballistic missiles (ICBMs) and one of four countries with anti-ballistic missile systems. Since 2016, India has been a member of Missile Technology Control Regime (MTCR).
Missile defense systems are a type of missile defense intended to shield a country against incoming missiles, such as intercontinental ballistic missiles (ICBMs) or other ballistic missiles. The United States, Russia, India, France, Israel, Italy, United Kingdom, China and Iran have all developed missile defense systems.
