The Defence Acquisition Council by the Nirmala Sitharaman-led cleared a (NASAM) missile deal with America worth Rs 6,500 crore. India would send a letter of request to the American administration for implementing the government to government deal.
The programme is being undertaken as the threat perception from incoming enemy missiles, drones and aircraft are on the rise because of their increasing use by terrorist organizations such as the Lashkar-e-Taiba. The same anti-missile system is used by the Americans to guard their national capital region in Washington DC and has been in deployment there since 2005
The National Advanced Surface to Air Missile System (NASAMS) is a medium-range, network-centric air defence system designed and developed jointly by Raytheon and Kongsberg Defence & Aerospace, primarily for the Royal Norwegian Air Force.
The system can be deployed to identify, engage and destroy aircraft, helicopters, cruise missiles and unmanned aerial vechile, as well as protect high-value assets and mass population centers against air-to-surface threats.
The NASAMS air defence system features network centric, open architecture that provides increased survivability against electronic countermeasures. The missile system can engage 72 targets simultaneously in active and passive modes. The primary weapon of the system is AIM-120 AMRAAM.
Raytheon MPQ-64F1 Sentinel high-resolution, 3D pencil beam surveillance radar is fitted to the NASAMS to detect and track the targets. The missile system is also fitted with AMRAAM launchers and a passive electron-optic (EO) and infra-red (IR) sensor, hard-real-time communication network and an embedded and stand alone mission planning tool.
The NASAMS is equipped with three multi-mission launchers, each carrying up to six ready-to-fire missiles inside the protective canisters. It can be carried on truck and rail. The system features a 360° defence capability and is suitable for day and night, all-weather operations
The NASAMS is fitted with a fire distribution centre (FDC) command-and-control unit to perform the battle management command, control, communications, computers and intelligence (BMC4I) functions. It is also used for data link management, track identification and correlation, friendly protection, jam strobe triangulation, threat evaluation, weapon allocation and kill assessment.The FDC and radars are connected using Link 16, JRE, Link 11, Link 11B, LLAPI and ATDL-1 data links.
NASAMS is under continuous development and every new program is adapted to the latest available technology. Currently, NASAMS is in use in 6 different nations.
