Swordfish is an Indian active electronically scanned array (AESA) [1] [2] 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. [3] 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. [4]

Development

Indian Armed Forces acquired two Green Pine long range base variant radar from Israel in July 2002 and August 2005 since USA vetoed the complete sale of Arrow 2 missile defense system in 1999 due to violation of Missile Technology Control Regime (MTCR) which India at that time was not a participating member state. [5] From March 2009, DRDO started validation trials for its own long-range capabilities of Swordfish radar. [3] [6] More tests were conducted in 2009 to enhance the capabilities of Advanced Air Defence (AAD) endo-atmospheric missile to intercept incoming missiles at altitudes up to 15 km. If no issues crop up, then the tentative date for deployment is 2015. As of January 2019, Swordfish was able to detect over 10 successful missile interceptions that includes two exo-atmospheric hit-to-kill missions. [4]

Super Swordfish

A new upgraded 1,500 km range Super Swordfish Long Range Tracking Radar or LRTR-II was developed since 2011 by the Electronics and Radar Development Establishment (LRDE) in view of multiple independently targetable reentry vehicle (MIRV) development taking place in China and Pakistan. [7] [8] [9] [10] [11]

Indian Space Research Organisation (ISRO) is already using an L band AESA radar called Multi Object Tracking Radar (MOTR) which is based on the same technology with fixed horizontal and vertical angle rotating at 360°. It is capable of tracking 0.25 m² object at 1,000 km and 0.09 m² at 800 km of Low Earth Orbit (LEO). Astra Microwave developed the antenna, transmit and receive (T/R) module and DC-to-DC converter. NS Engineering created the cooling system and mechanical structure. Cape Electronics developed the power distribution system. [12] [13] [14]

As per Ministry of Defence (MoD), the system is operationaland deployed as per Ballistic Missile Defence of Delhi NCR. A minimum of two units of LRTR-II were tested in real-world conditions. The radar will be also deployed in Eastern Sector. [15] [16]

VLRTR

The LRTR series of radars has been succeeded by the VLRTR. The VLRTR, or Very Long Range Tracking Radar, has a range exceeding 3,000 km. The GaN-based TRMs may be used by Very Long Range Tracking Radar.

To support ballistic missile defence, the Missile Monitoring System uses VLRTR to identify space-borne threats. After the government approved the installation of two additional Very Long Range Tracking Radars (VLRTR) units under an MOU between the NTRO and the IAF to implement a Missile Monitoring System to identify space-borne threats in support of Ballistic Missile Defence (BMD), the first VLRTR went into service in 2017.

As per Ministry of Defence (MoD), two units of VLRTR systems were accorded by Union Government under memorandum of understanding (MoU) between National Technical Research Organisation (NTRO) and Indian Air Force for Indian Ballistic Missile Defence Programme. First unit was raised in 2017 and the system is operational. [15] [16]

An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles. Ballistic missiles are used to deliver nuclear, chemical, biological, or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" is a generic term for a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs).
