Swordfish Long Range Tracking Radar
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. 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. From March 2009, DRDO started validation trials for its own long-range capabilities of Swordfish radar. 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. Variant. Super Swordfish Long Range Tracking Radar / Very Long Range Tracking Radar (VLRTR). A new upgraded 1,500 km range "Super Swordfish Long Range Tracking Radar" is under development by the Electronics and Radar Development Establishment (LRDE) from 2011 in view of multiple independently targetable reentry vehicle (MIRV) development taking place in China and Pakistan. 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. The upgraded Super Swordfish Long Range Tracking Radar was raised in 2017 for Indian Ballistic Missile Defense Programme and is now operational.
