Swordfish is an Indian long-range tracking radar specifically developed to counter ballistic missile threat. It will be a part of India's ballistic missile program. First testing of this radar was in March 2009. Main aim of the test was to validate the capabilities of the indigenously developed 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.
Swordfish is an acknowledged derivative of the Israeli Green Pine long range radar, which is the critical component of that country's Arrow missile defence 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.
Target acquisition and fire control radar for the BMD system.
Can Guide Exo-atmospheric interceptor missile PAD to hit its target in space at an altitude over 80 km from earth.
The Swordfish LRTR currently has a range of 600 km (370 mi)-800 km (500 mi) km range and can spot objects as small as a cricket ball (3-inches in diameter), which the DRDO is in the process of upgrading it to 1,500 km as of 2012. These may end up as entirely new designs as well.
More tests were conducted in 2009 to enhance the capabilities of AAD endo-atmospheric missile to intercept missiles at altitudes up to 15 km. If no issues crop up, then the tentative date for deployment is 2015.
In March 2009, India DRDO tested long-range capabilities of its indigenously developed Swordfish radar.
